3e087b5754 [BLOCK] update IDE to use new blk_ordered for barriers
Update IDE to use new blk_ordered.  This change makes the
following behavior changes.

* Partial completion of the barrier request is handled as
  failure of the whole ordered sequence.  No more partial
  completion for barrier requests.

* Any failure of pre or post flush request results in failure
  of the whole ordered sequence.

So, successfully completed ordered sequence guarantees that
all requests prior to the barrier made to physical medium and,
then, the while barrier request made to the physical medium.

All ordered request related stuff delegated to HLD.  Midlayer

8ffdc6550c [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()
add @uptodate argument to end_that_request_last() and @error
to rq_end_io_fn().  there's no generic way to pass error code
to request completion function, making generic error handling
of non-fs request difficult (rq->errors is driver-specific and
each driver uses it differently).  this patch adds @uptodate
to end_that_request_last() and @error to rq_end_io_fn().

for fs requests, this doesn't really matter, so just using the
same uptodate argument used in the last call to
end_that_request_first() should suffice.  imho, this can also
help the generic command-carrying request jens is working on.

9f155b9802 [PATCH] i386: PTRACE_POKEUSR: allow changing RF bit in EFLAGS register.
Setting RF (resume flag) allows a debugger to resume execution after a
code breakpoint without tripping the breakpoint again.  It is reset by
the CPU after execution of one instruction.

Requested by Stephane Eranian:
  "I am trying to the user HW debug registers on i386 and I am running
   into a problem with ptrace() not allowing access to EFLAGS_RF for
   POKEUSER (see FLAG_MASK).  [ ...  ] It avoids the need to remove the
   breakpoint, single step, and reinstall.  The equivalent functionality
   exists on IA-64 and is allowed by ptrace()"

3b27e9421a [PATCH] pcmcia: properly handle static mem, but dynamic io sockets
Some PCMCIA sockets have statically mapped memory windows, but dynamically
mapped IO windows. Using the "nonstatic" socket library is inpractical for
them, as they do neither need a resource database (as we can trust the
kernel resource database on m68k and ppc) nor lots of other features of that
library. Let them get a small "iodyn" socket library (105 lines of code)
instead.

f8cfa618dc [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback
Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:

        int (*probe)            (struct pcmcia_device *dev);
        void (*remove)          (struct pcmcia_device *dev);

        int (*suspend)          (struct pcmcia_device *dev);
        int (*resume)           (struct pcmcia_device *dev);

5b373e10ae [ATYFB]: Fix onboard video on SPARC Blade 100 for 2.6.{13,14,15}
I have recently been switching from using 2.4.32 on my trusty
old Sparc Blade 100 to using 2.6.15 .  Some of the problems I ran into
were distorted video when the console was active (missing first
character, skipped dots) and when running X windows (colored snow,
stripes, missing pixels).  A quick examination of the 2.6 versus 2.4
source for the ATY driver revealed alot of changes.

         A closer look at the code/data for the 64GR/XL chip revealed
two minor "typos" that the rewriter(s) of the code made.  The first is
a incorrect clock value (230 .vs. 235) and the second is a missing
flag (M64F_SDRAM_MAGIC_PLL).  Making both these changes seems to have
fixed my problem.  I tend to think the 235 value is the correct one,
as there is a 29.4 Mhz clock crystal close to the video chip and 235.2
(29.4*8) is too close to 235 to make it a coincidence.

	The flag for M64F_SDRAM_MAGIC_PLL was dropped during the
changes made by adaplas in file revision 1.72 on the old bitkeeper
repository.

	The change relating to the clock rate has been there forever,
at least in the 2.6 tree.  I'm not sure where to look for the old 2.5
tree or if anyone cares when it happened.

On SPARC Blades 100's, which use the ATY MACH64GR video chipset, the
clock crystal frequency is 235.2 Mhz, not 230 Mhz.  The chipset also
requires the use of M64F_SDRAM_MAGIC_PLL in order to setup the PLL
properly for the DRAM.
