d626f62b11 [SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}
To clearly state the intent of copying from linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

53077944f1 [PATCH] wireless: More WE-21 potential overflows...
After the Orinoco issue, I did an audit of other drivers for the same
issue.  Three drivers were NULL terminating the ESSID, which could cause an
overflow in WE-21 when the ESSID has maximum size.

7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

7345137930 [PATCH] wireless/atmel: fix Open System authentication process bugs
This patch fixes a number of bugs in the authentication process:

1) When falling back to Shared Key authentication mode from Open System,
a missing 'return' would cause the auth request to be sent, but would
drop the card into Management Error state.  When falling back, the
driver should also indicate that it is switching to Shared Key mode by
setting exclude_unencrypted.

2) Initial authentication modes were apparently wrong in some cases,
causing the driver to attempt Shared Key authentication mode when in
fact the access point didn't support that mode or even had WEP disabled.
The driver should set the correct initial authentication mode based on
wep_is_on and exclude_unencrypted.

3) Authentication response packets from the access point in Open System
mode were getting ignored because the driver was expecting the sequence
number of a Shared Key mode response.  The patch separates the OS and SK
mode handling to provide the correct behavior.

d6a13a24b7 [PATCH] drivers/net/wireless: correct reported ssid lengths
ESSIDs can technically include NULL characters.  Drivers should not be
adjusting the length of the ESSID before reporting it in their

problem.

9a6301c114 [PATCH] wireless/atmel: add IWENCODEEXT, IWAUTH, and association event support
This patch allows the Atmel driver to work correctly with wpa_supplicant
and other programs that require some conformance with WEXT-18.  It
should not affect current behavior of the driver.  The patch does four
things:

1) Implements SIOCSIWENCODEEXT, SIOCGIWENCODEEXT, SIOCSIWAUTH, and
SIOCGIWAUTH calls for unencrypted and WEP operation

2) Accepts zero-filled addresses for SIOCSIWAP, which are legal and
should turn off any previous forced WAP address

3) Sends association and de-association events to userspace at most of
the appropriate times

4) Fixes erroneous order of CIPHER_SUITE_WEP_* arguments in one location
which are actually unused anyway

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
