Stefan Richter 5d59a6f1ba firewire: remove bogus check in fw_core_handle_request
This check is bogus:
  - Maximum asynchronous payload size for S800...S3200 is 4096.
  - The p->payload_length is totally uninteresting.  Only the
    request->length of the subsequently allocated and initialized
    struct fw_request is of significance.

Roland Dreier 43509d1fec IB/mthca: Simplify use of size0 in work request posting
Current code sets size0 to 0 at the start of work request posting
functions and then handles size0 == 0 specially within the loop over
work requests.  Change this so size0 is set along with f0 the first
time through the loop (when nreq == 0).  This makes the code easier to
understand by making it clearer that f0 and size0 are always
initialized if nreq != 0 without having to know that size0 == 0
implies nreq == 0.

Also annotate size0 with uninitialized_var() so that this doesn't
introduce a new compiler warning.

Haavard Skinnemoen 3da86ee4f1 [AVR32] Fix atomic_add_unless() and atomic_sub_unless()
These functions depend on "result" being initalized to 0, but "result"
is not included as an input constraint to the inline assembly block
following its initialization, only as an output constraint. Thus gcc
thinks it doesn't need to initialize it, so result ends up undefined
if the "unless" condition is true.

This fixes an oops in sunrpc where the faulty atomics caused
rpciod_up() to not start the workqueue as it should.

Haavard Skinnemoen e122eaf694 [AVR32] Remove optimization of unaligned word loads
If we let unaligned word loads bypass the generic unaligned handling,
gcc may combine it with a swap.b instruction and turn it into a ldwsp
instruction, which does not work with unaligned addresses.

Revert the optimization to prevent the RNDIS driver from crashing.
Hopefully we'll figure something out later (it may be better to do the
optimization in gcc.)

This adds some STK1002-specific config options covering the jumper settings,
so the kernel can automatically be configured to include the relevant devices.

One of them replaces the previous internal SW2_DEFAULT setting; SPI config
is affected by two of the jumpers; and a fourth one switches between LCD and
the second Ethernet connector.  (There's more that to be done.)

Hans-Christian Egtvedt 9e58e1855c [AVR32] CPU frequency scaling for AT32AP
This patch enables CPU frequency scaling for AT32AP devices. This will
enable the CPU to scale between the speed of the high speed bus and
the master clock and thus save some power.

The patch also adds a parent to cpu_clk and a cpu_clk_set_rate to
enable changing the CPU clock divider in a sane way.

The driver does not check if the given rate is 0, thus resulting in a
div by 0.  I think this check should be go into the clk_set_rate
framework, and not here.

Tested on AT32AP7000/ATSTK1000.

Hardware documentation can be found in the AT32AP7000 datasheet.

The result is always faster and smaller for 8, 16, and 32 bit values.
For 64 bit quantities, it's presumably larger.

H. Peter Anvin 8c027ae2dc [x86 setup] Save/restore DS around invocations of INT 10h
There exists at least one card, Trident TVGA8900CL (BIOS dated 1992/9/8)
which clobbers DS when "scrolling in an SVGA text mode of more than
800x600 pixels."  Although we are extremely unlikely to run into that
situation, it is cheap insurance to save and restore DS, and it only adds
a grand total of 50 bytes to the total output.

H. Peter Anvin 7ad37df02c [x86 setup] VGA: Clear the Protect bit before setting the vertical height
If the user has asked for the vertical height registers to be recomputed
by setting bit 15 in the video mode number, we do so without clearing the
Protect bit in the Vertical Retrace Register before setting the Overflow
register.  As a result, if the VGA BIOS had set the Protect bit, the
write to the Overflow register will be dropped, and bits [9:8] of the
vertical height will be left unchanged.

This is a bug imported from the assembly version of this code.  It was
pointed out by Etienne Lorrain.

H. Peter Anvin 5593eaa854 [x86 setup] Fix assembly constraints
Fix incorrect assembly constraints.  In particular, fix memory
constraints used inside push..pop, which can cause invalid operation
since gcc may generate %esp-relative references.

Additionally:

outl() should have "dN" not "dn".

query_mca() shouldn't listen 16/32-bit registers in an 8-bit only
context.

has_eflag(): the "mask" is only used well after both the stack pointer
and the output registers have been touched; this requires the output
registers to be earlyclobbers (=&) and the input to exclude memory (so
"ri", not "g").

Mauro Carvalho Chehab 3ea9661538 V4L/DVB (5840): fix dst and cx24123: tune() callback changed signess for delay
tune() dvb_frontend callback changed delay signess:
        int (*tune)(struct dvb_frontend* fe,
                    struct dvb_frontend_parameters* params,
                    unsigned int mode_flags,
-                   int *delay,
+                   unsigned int *delay,

This change caused warnings on cx24123 and dst modules:

/home/v4l/master/v4l/cx24123.c:1034: warning: initialization from incompatible pointer type
/home/v4l/master/v4l/dst.c:1782: warning: initialization from incompatible pointer type
/home/v4l/master/v4l/dst.c:1808: warning: initialization from incompatible pointer type
/home/v4l/master/v4l/dst.c:1837: warning: initialization from incompatible pointer type
/home/v4l/master/v4l/dst.c:1860: warning: initialization from incompatible pointer type

This patch corrects the function prototype on both modules to follow the
core change.

Trent Piepho 372280d2a3 V4L/DVB (5834): dvb-core: fix signedness warnings and const stripping
Make some pointers const, and then delete some now unnecessary casts,
which were the wrong signedness anyway, being used to strip the const
from another pointer.

New code is simpler, shorter, compiles to about half the size, and is 2
to 4 times faster depending on how many bits in the mask are set.
