PIO4 is a maximum PIO mode supported by a driver. Using "255" as a max_mode
argument to ide_get_best_pio_mode() could result in wrong timings being used
by a driver (for "pio" equal to 5) or OOPS (for "pio" values > 5 && < 255).

The SiS966 has one additional PCI-ID 1180.
If the chipset is using this PCI-ID, the primary channel is connected to the
first PATA-port. The secondary channel is connected to SATA-ports in IDE
emulation mode. The legacy IO-ports are used.
The including of the PCI-ID into pata_sis is not sufficient, because the legacy
driver in drivers/ide is initialized before pata_sis.

In 7d12e780e0 David Howells performed
this evolution:
"IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"
He correctly updated many of the function definitions that were using this
extra regs pointer parameter but forgot to update some caller sites of
those functions. The reason the modifications was not properly done on all
drivers is that some drivers were rarely compiled because they are for
AMIGA, or that some code sites were inside #ifdefs where the option is not
set or inside #if 0.
Here is the semantic patch that found the occurences
and fixed the problem.

When we enable the SMCf010 IR device, the Toshiba Portege 4000 BIOS claims
the device is working, but it really isn't configured correctly. The BIOS
*will* configure it, but only if we call _SRS after (1) reversing the order
of the SIR and FIR I/O port regions and (2) changing the IRQ from
active-high to active-low.
This patch addresses the 2.6.22 regression:
"no irda0 interface (2.6.21 was OK), smsc does not find chip"
I tested this on a Portege 4000. The smsc-ircc2 driver correctly detects
the device, and "irattach irda0 -s && irdadump" shows transmitted and
received packets.

cinergyT2.c does cancel_delayed_work() + flush_scheduled_work() while

needs the same mutex to complete. Another bug is that this code in fact

Convert this code to use cancel_rearming_delayed_work() and move it
out of ->sem. Another mutex, ->wq_sem, was added to protect against the
concurrent open/resume.

If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as
the first user after the driver is loaded, the driver wedges itself and will
never capture properly. Even if one uses a V4L2 application later, it still
won't work.
If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2
driver, then the driver will be ok. One can then run a V4L1 application, and
it will work.
It turns out the problem is with norm changing and the crop support that was
added in 2.6.21. The driver defaults to PAL, and keeps the last norm it was
set too across opens. If one changes the norm via V4L1, the cropping
parameters are not reset like they should be, and they'll remain broken across
device opens.
This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl
VIDIOCSCHAN handler. The norm is set via the existing call to set_input(),
which calls set_tvnorm(), which will reset the cropping values now that it is
able to detect the norm change.

If asus_acpi_init doesn't find any device it knows about, it mistakenly
returns a "success" error code even though it cleans up after itself. Later
when trying to rmmod asus_acpi, the module_exit routine would try to clean up
one more time and we would end up calling
acpi_bus_unregister_driver(&asus_hotk_driver) twice. This patch addresses
this first problem by returning -ENODEV when no appropriate device is found.
Then there was also another bug with the code handling the return value of
backlight_device_register. If this function ever failed, the driver would
cleanup by calling the module_exit routine from module_init, but it would
still return "success". So any attempt to rmmod this module would result in
asus_acpi_exit being called twice but it's not ready to handle it (I haven't
hit this bug, just found it by code inspection). This patch fixes that by
inserting a return -ENODEV; at the end of this error handling path.

The interrupt clearing code in mpsc_sdma_intr_ack() mistakenly clears the
interrupt for both controllers instead of just the one its supposed to.
This can result in the other controller appearing to hang because its
interrupt was effectively lost.
So, don't clear the interrupt cause bits for both MPSC controllers when
clearing the interrupt for one of them. Just clear the one that is
supposed to be cleared.

This patch changes the test for the thread pid from >= 0 to > 0.
When the saa8134 driver initialization fails after a certain point, it goes
through the complete shutdown process for the driver. Part of shutting it
down includes tearing down the thread for tv audio.
The test for tearing down the thread tests for >= 0. Since the dev
structure is kzalloc'd, the test will always be true if we haven't tried to
start the thread yet. We end up waiting on pid 0 to complete, which will
never happen, so we lock up.

If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set
y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool
promotes the tristate from m to y.
This ends up causing a problem with several menuconfigs that look like:
menuconfig BAR
bool
depends on BAZ [tristate]
if BAR
config FOO
tristate
endif
The solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ. This is how it would work if a menu
was used instead of an if block.

Some HP firmware leaves the SMCf010 IRDA device incompletely configured, or
reports the wrong resources in _CRS. As a workaround, when we find such a
device, try to auto-configure the device.
This ignores the _CRS data, picks a config from _PRS, and runs _SRS to
configure the device. This makes smsc-ircc2 work correctly with PNP
resources (with no preconfiguration!) on all the machines I tested.
I think Windows does something like this by default for all devices,
so we should consider doing the same thing in Linux.
This patch addresses part of the 2.6.22 regression:
"no irda0 interface (2.6.21 was OK), smsc does not find chip"
It fixes smsc-ircc2 PNP device detection on HP nc6000, nc6220, nw8000,

Recently my console UTF-8 patch went mainline. Here is an additional patch
that fixes two nasty issues and improves a third one, namely:
1. My patch changed the behavior if a glyph is not found in the Unicode
mapping table. Previously for Unicode values less than 256 or 512 the
kernel tried to display the glyph from that position of the glyph table,
which could lead to a different accented letter being displayed. I
removed this fallback possibility and changed it to display the
replacement symbol.
As Behdad pointed out, some fonts (e.g. sun12x22 from the kbd package)
lack Unicode mapping information, hence all you get is lots of question
marks. Though theoretically it's actually a user-space bug (the font
should be fixed), Behdad and I both believe that it'd be good to work
around in the kernel by re-introducing the fallback solution for ASCII
characters only. This sounds a quite reasonable decision, since all fonts
ship the ASCII characters in the first 128 positions. This way users
won't be surprised by lots of question marks just because s/he issued a
not-so-perfectly parameterized setfont command. As this fallback is only
re-introduced for code points below 128, you still won't see an accented
letter replaced by another, but at least you'll always get the English
letters right.
2. My patch introduced "question mark with inverted color attributes" as a
last resort fallback glyph. Though it perfectly works on VGA console, on
framebuffer you may end up with question marks that are highlighed but
shouldn't be, and normal characters that are accidentally highlighed.
This is caused by missing FLUSHes when changing the color attribute.
3. I've updated the table of double-width character based on Markus's
updated version. Only ten new code poings (one interval) is added.

Code intended to check DMA status was checking DMA command register.
Moreover firmware seems to "forget" to set DMA capable bit for the
slave device (at least in RAID mode but without ITE RAID volumes) so
check device ID for DMA capable bit when deciding whether to use DMA
and remove DMA status check completely.
Thanks to Pavol Simo for the bugreport and testing the initial fix.
This change unfortunately still doesn't fix DMA in RAID mode (which
works fine with IDE it821x) but Alan is working on the missing pieces

This patch fixes a rare deadlock that can occur when the kernel
is not able to empty out the RX ring quickly enough. Below follows
a detailed description of the bug and the fix.
As long as the OS can empty out the RX buffers at a rate faster than
the hardware can fill them, there is no problem. If, for some reason,
the OS fails to empty the RX ring fast enough, the hardware GDACTDPA
pointer will catch up to the head, notice the not-empty condition,
ad stop. However, RX packets may still continue arriving on the wire.
The spidernet chip can save some limited number of these in local RAM.
When this local ram fills up, the spider chip will issue an interrupt
indicating this (GHIINT0STS will show ERRINT, and the GRMFLLINT bit
will be set in GHIINT1STS). When te RX ram full condition occurs,
a certain bug/feature is triggered that has to be specially handled.
This section describes the special handling for this condition.
When the OS finally has a chance to run, it will empty out the RX ring.
In particular, it will clear the descriptor on which the hardware had
stopped. However, once the hardware has decided that a certain
descriptor is invalid, it will not restart at that descriptor; instead
it will restart at the next descr. This potentially will lead to a
deadlock condition, as the tail pointer will be pointing at this descr,
which, from the OS point of view, is empty; the OS will be waiting for
this descr to be filled. However, the hardware has skipped this descr,
and is filling the next descrs. Since the OS doesn't see this, there
is a potential deadlock, with the OS waiting for one descr to fill,
while the hardware is waiting for a differen set of descrs to become
empty.
A call to show_rx_chain() at this point indicates the nature of the
problem. A typical print when the network is hung shows the following:
net eth1: Spider RX RAM full, incoming packets might be discarded!
net eth1: Total number of descrs=256
net eth1: Chain tail located at descr=255
net eth1: Chain head is at 255
net eth1: HW curr desc (GDACTDPA) is at 0
net eth1: Have 1 descrs with stat=xa0800000
net eth1: HW next desc (GDACNEXTDA) is at 1
net eth1: Have 127 descrs with stat=x40800101
net eth1: Have 1 descrs with stat=x40800001
net eth1: Have 126 descrs with stat=x40800101
net eth1: Last 1 descrs with stat=xa0800000
Both the tail and head pointers are pointing at descr 255, which is
marked xa... which is "empty". Thus, from the OS point of view, there
is nothing to be done. In particular, there is the implicit assumption
that everything in front of the "empty" descr must surely also be empty,
as explained in the last section. The OS is waiting for descr 255 to
become non-empty, which, in this case, will never happen.
The HW pointer is at descr 0. This descr is marked 0x4.. or "full".
Since its already full, the hardware can do nothing more, and thus has
halted processing. Notice that descrs 0 through 254 are all marked
"full", while descr 254 and 255 are empty. (The "Last 1 descrs" is
descr 254, since tail was at 255.) Thus, the system is deadlocked,
and there can be no forward progress; the OS thinks there's nothing
to do, and the hardware has nowhere to put incoming data.
This bug/feature is worked around with the spider_net_resync_head_ptr()
routine. When the driver receives RX interrupts, but an examination
of the RX chain seems to show it is empty, then it is probable that
the hardware has skipped a descr or two (sometimes dozens under heavy
network conditions). The spider_net_resync_head_ptr() subroutine will
search the ring for the next full descr, and the driver will resume
operations there. Since this will leave "holes" in the ring, there
is also a spider_net_resync_tail_ptr() that will skip over such holes.

The calculation of max_inline_data in set_kernel_sq_size() is bogus,
since it doesn't take into account the fact that inline segments may
not cross a 64-byte boundary, and hence multiple inline segments will
probably need to be used to post large inline sends.
We don't support inline sends for kernel QPs anyway, so there's no
point in doing this calculation anyway, since the field is just zeroed
out a little later. So just delete the bogus calculation.

New ConnectX firmware introduces FW command interface revision 2,
which requires that for each QP, a chunk of send queue entries (the
"headroom") is kept marked as invalid, so that the HCA doesn't get
confused if it prefetches entries that haven't been posted yet. Add
code to the driver to do this, and also update the user ABI so that
userspace can request that the prefetcher be turned off for userspace
QPs (we just leave the prefetcher on for all kernel QPs).
Unfortunately, marking send queue entries this way is confuses older
firmware, so we change the driver to allow only FW command interface
revisions 2. This means that users will have to update their firmware
to work with the new driver, but the firmware is changing quickly and
the old firmware has lots of other bugs anyway, so this shouldn't be too
big a deal.

Commit 9b01bd5b28 introduced a
compat_ioctl handler for RADEON_SETPARAM, the sole purpose of which was
to handle the fact that on i386, alignof(uint64_t)==4.
Unfortunately, this handler was installed for _all_ 64-bit
architectures, instead of only x86_64 and ia64. And thus it breaks
32-bit compatibility on every other arch, where 64-bit integers are
aligned to 8 bytes in 32-bit mode just the same as in 64-bit mode.
Arnd has a cunning plan to use 'compat_u64' with appropriate alignment
attributes according to the 32-bit ABI, but for now let's just make the
compat_radeon_cp_setparam routine entirely disappear on 64-bit machines
whose 32-bit compat support isn't for i386. It would be a no-op with
compat_u64 anyway.

This patch trys to fix device probe in two cases. First we should
correctly detect device if integrated graphics device is not enabled
or exists, like an add-in card is plugged. Second on some type of intel
GMCH, it might have multiple graphic chip models, like 945GME case, so
we should be sure the detect works through the whole table.

This reverts commit d52df4a35a.
This patch attempted to fix e100 for non-cache coherent memory
architectures by using the cb style code that eepro100 had and using
the EL and s bits from the RFD list. Unfortunately the hardware
doesn't work exactly like this and therefore this patch actually
breaks e100. Reverting the change brings it back to the previously
known good state for 2.6.22. The pending rewrite in progress to this
code can then be safely merged later.

With firmware 5.220.11.p5, this allows to specify the anycast addresses the
device will listen to.
The anycast address range is C0:27:C0:27:C0:XX where XX goes from 00 to 1F (or
0 to 31 in dec). The value to write on anycast_mask will specify which
addresses the device listens to. Bits in a 32 bit int are numbered from 0
(least significative bit) to 31. A specific address ending in YY will be
listened to if bit YY in the value is set to one.
Examples:
0x00000000 : do not listen to any anycast address
0xFFFFFFFF : listen to every anycast address from :00 to :1F
0x00000013 : listen to anycast addresses :00, :01 and :04

The BSS to associate with (in either Infrastructure or IBSS join
operations) is now stored in _one_ place in the association request (the
bss member), not two places as before (pattemptedbss and
curbssparams->bssdescriptor).
Association requests are passed to the necessary association functions
to (a) give them access to the bss member and (b) ensure that
association/join/start setup uses settings from the request, not the
current adapter settings (which may not be valid for the requested
settings).
Because the 'bss' member of the association request is used now, the
command return functions from associate and adhoc join/start need access
to the in-progress association request to update curbssparams when
everything is done. The association worker moves the request from
pending to in-progress for the duration of the association attempt.

After SRST, libata used to wait for nsect/lbal to be set to 1/1 for
the slave device. However, some ATAPI devices don't set nsect/lbal
after SRST and the wait itself isn't too useful as we're gonna wait
for !BSY right after that anyway.
Before reset-seq update, nsect/lbal wait failure used to be ignored
and caused 30sec delay during detection. After reset-seq, all
timeouts are considered error conditions making libata fail to detect
such ATAPI devices.
This patch limits nsect/lbal wait to around 100ms. This should give
acceptable behavior to such ATAPI devices while not disturbing the
heavily used code path too much.

The ata IRQ ack functions are only used when debugging. Unfortunately
almost every controller that calls them can cause crashes in some
configurations as there are missing checks for bmdma presence.
In addition ata_port_start insists of installing DMA buffers and pad
buffers for controllers regardless. The SFF controllers actually need to
make that decision dynamically at controller setup time and all need the
same helper - so we add ata_sff_port_start. Future patches will switch
the SFF drivers to use this.

Most drivers don't seem to fill out the host->irq field, resulting in the
wrong (no) irq being reported at probe time. For example, sil24 on my system:
ata1: SATA max UDMA/100 cmd 0xd00008009001f000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0

NetXen: Fix initialization and subsequent ping issue on 3.4.19 firmware
This patch fixes the ping problem seen X/PBlades after the adapter's
firmware was moved to 3.4.19. After configured interface up, ping
failed.
NetXen adapter couldn't accept ARP broadcast packet. Manual addition of
MAC address in the ARP table, made ping work.
NetXen adapter should finish initilization after system boot. But looks
NetXen adapter didn't initilization correctly after system boot up.
So have to re-load the firmware again in probe routine.
Also re-initilization netxen_config_0 and netxen_config_1 registers.

sata_promise uses two different command modes - packet and TF. Packet mode
is intelligent low-overhead mode while TF is the same old taskfile
interface. As with other advanced interface (ahci/sil24),
ATA_TFLAG_POLLING has no effect in packet mode. However, PIO commands are
issued using TF interface in polling mode, so pdc_interrupt() considers
interrupts spurious if ATA_TFLAG_POLLING is set.
This is broken for polling NODATA commands because command is issued using
packet mode but the interrupt handler ignores it due to ATA_TFLAG_POLLING.
Fix pdc_qc_issue_prot() such that ATA/ATAPI NODATA commands are issued
using TF interface if ATA_TFLAG_POLLING is set.
This patch fixes detection failure introduced by polling SETXFERMODE.

The sysfs adsl_status attribute ignores (aside from returning -EIO to the
user) any error sending a START/STOP command to the device and there is at
least one firmware which never sends a response but appears to work
regardless. Therefore atm_start should also continue if an error is received
so that such firmware is usable.
The official Conexant driver doesn't expect a reply either but this is for
another device (E2 router) and a commonly used firmware does respond.
Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing
ever checks for either of these values.

Since usbatm doesn't set the usb_interface driver data until after calling
bind and heavy_init, it would be NULL when the sysfs attributes are read.
Reading the MAC address from atm_dev before atm_dev exists would have been
be possible too.
Calling create_device_file in atm_start will avoid this problem, and the
data is useless until the first status poll runs. However, it must be
ready before a status poll does a printk on line status change otherwise
userspace could react before the files exist.
For completeness I've moved remove_device_file to atm_stop so it's not
called in unbind when it's not needed. There's no point starting ADSL if
atm_start could still fail either.

It turns out that le16_to_cpup() and le32_to_cpup() aren't always safe
to call with pointers into packed structures, since those are inlined
functions and GCC may lose the "packed" attribute. So those references
can become unaligned kernel accesses, which are evil on some hardware.
This patch updates uses of those routines in the gadget stack. The
references into packed structures can just use leXX_to_cpu(*x), which
in most cases is more natural. Some other uses in RNDIS, mostly in
debug code, were wrong in the first place; those use get_unaligned().
