[PATCH] Update cyblafb driver
This is a major update to the cyblafb framebuffer driver. Most
of the stuff has been tested in the mm tree.
Main advantages:
============
- vxres > xres support
- ywrap and xpan support
- much faster for almost all modes (e.g. 1280x1024-16bpp
draws more than 41 full screens of text instead of about 25
full screens of text per second on authors Epia 5000)
- module init/exit code fixed
- bugs triggered by console rotation fixed
- lots of minor improvements
- startup modes suitable for high performance scrolling
in all directions
This diff also contains a lot of white space fixes.
No side effects are possible, only one single graphics core is affected.

[PATCH] sata_nv, spurious interrupts at system startup with MAXTOR 6H500F0 drive
This patch works around a problem with spurious interrupts seen at boot time when
a MAXTOR 6H500F0 drive is present. An ATA interrupt condition is mysteriously
present at start of day. If we took too long in issuing the first command,
the kernel would basically get tired of the spurious interrupts and turn the interrupt
off. Issuing the first command essentially causes the interrupt condition to
get acknowledged.
I haven't seen this happen with any other drives.
What I basically do is ack ATA status by reading it regardless of whether we're
expecting to have to handle an interrupt. This clears the start-of-day anomalous
interrupt condition, and keeps the kernel from disabling that interrupt due to
too many spurious interrupts.
Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled
in the ISR. This was not the cause of the spurious interrupts, but it's the right
thing to do anyway.

Previously, the host_build_iv flag couldn't be used at all for WEP, and
not alone (with both host_decrypt and host_encrypt disabled) because the

devices for which a backend is provided). This should replace the clock
spreading hacks properly. It might also have an impact on all sort of
machines since some of the scripts marked "at init" will now be executed
on boot (or some other on sleep/wakeup), those will possibly do things
that the kernel didn't do at all, like setting some values into some i2c
devices (changing thermal sensor calibration or conversion rate) etc...
Thus regression testing is MUCH welcome. Also loook for errors in dmesg.
That's also why I've left rather verbose debugging enabled in this
version of the patch.
(I do expect some Windtunnel G4s to show some errors as they have an i2c
clock chip on the PMU bus that uses some primitives that the i2c backend
doesn't implement yet. I really need users that have one of those
machine to come back to me so we can get that done right, though the
errors themselves should be harmless, I suspect the machine might not

[PATCH] ppc64: fix time syscall
ppc64 has its own version of sys_time. It looks pretty scary, touching
a whole bunch of variables without any locking or memory ordering.
In fact, a recent bugreport has shown it can actually go backwards. Time
to remove it and just use the generic sys_time, which is implemented on
top of do_gettimeofday.

[PATCH] ppc32: Put cache flush routines back into .relocate_code section
In 2.6.14, we had the following definition of _GLOBAL() in
include/asm-ppc/processor.h:
#define _GLOBAL(n)\
.stabs __stringify(n:F-1),N_FUN,0,0,n;\
.globl n;\
n:
In 2.6.15, as part of the great powerpc merge, we moved this definition to
include/asm-powerpc/ppc_asm.h, where it appears (to 32-bit code) as:
#define _GLOBAL(n) \
.text; \
.stabs __stringify(n:F-1),N_FUN,0,0,n;\
.globl n; \
n:
Mostly, this is fine. However, we also have the following, in
arch/ppc/boot/common/util.S:
.section ".relocate_code","xa"
[...]
_GLOBAL(flush_instruction_cache)
[...]
_GLOBAL(flush_data_cache)
[...]
The addition of the .text section definition in the definition of
_GLOBAL overrides the .relocate_code section definition. As a result,
these two functions don't end up in .relocate_code, so they don't get
relocated correctly, and the boot fails.
There's another suspicious-looking usage at kernel/swsusp.S:37 that
someone should look into. I did not exhaustively search the source
tree, though.
The following is the minimal patch that fixes the immediate problem.
I could easily be convinced that the _GLOBAL definition should be
modified to remove the ".text;" line either instead of, or in addition
to, this fix.

[PATCH] spufs: set irq affinity for running threads
For far, all SPU triggered interrupts always end up on

This patch implements setting the affinity to the

In a hypervisor based setup, direct access to the first

As suggested by Masato Noguchi, let's abstract the register
access trough a number of function calls. Since there is

makes it easier to hook into.

[PATCH] fix workqueue oops during cpu offline
Use first_cpu(cpu_possible_map) for the single-thread workqueue case. We
used to hardcode 0, but that broke on systems where !cpu_possible(0) when
workqueue_struct->cpu_workqueue_struct was changed from a static array to
alloc_percpu.
Commit id
bce61dd49d6ba7799be2de17c772e4c701558f14 ("Fix hardcoded cpu=0 in
workqueue for per_cpu_ptr() calls") fixed that for Ben's funky sparc64
system, but it regressed my Power5. Offlining cpu 0 oopses upon the next
call to queue_work for a single-thread workqueue, because now we try to
manipulate per_cpu_ptr(wq->cpu_wq, 1), which is uninitialized.
So we need to establish an unchanging "slot" for single-thread workqueues
which will have a valid percpu allocation. Since alloc_percpu keys off of
cpu_possible_map, which must not change after initialization, make this
slot == first_cpu(cpu_possible_map).

Since version 4.1 the gcc is warning about ignored attributes. This patch is
using the equivalent attribute on the struct instead of on each of the

GCC Manual:
"Specifying Attributes of Types
packed
This attribute, attached to struct or union type definition, specifies
that
each member of the structure or union is placed to minimize the memory
required. When attached to an enum definition, it indicates that the
smallest integral type should be used.
