Allow initializing fans on systems where BIOS does not do that by
default.
- define f75375s_platform_data in new file f75375s.h
- if platform_data was provided, set fans accordingly in f75375_init()
- split set_pwm_enable() to a sysfs callback and directly usable
set_pwm_enable_direct()

This patch reverts Eric's commit 2b008b0a8e96b726c603c5e1a5a7a509b5f61e35
It diets .text & .data section of the kernel if CONFIG_NET_NS is not set.
This is safe after list operations cleanup.

SCTP-AUTH and future ADD-IP updates have a requirement to

ABORT the association if verification fails. So, introduce
additional return code so that we can clear signal a required

This patch adds a tunable that will allow ADD_IP to work without
AUTH for backward compatibility. The default value is off since
the default value for ADD_IP is off as well. People who need
to use ADD-IP with older implementations take risks of connection
hijacking and should consider upgrading or turning this tunable on.

After learning more about rcu, it looks like the ADD-IP hadling
doesn't need to call call_rcu_bh. All the rcu critical sections
use rcu_read_lock, so using call_rcu_bh is wrong here.
Now, restore the local_bh_disable() code blocks and use normal
call_rcu() calls. Also restore the missing return statement.

Commit d0ce92910bc04e107b2f3f2048f07e94f570035d broke several retransmit
cases including fast retransmit. The reason is that we should
only delay by rto while doing retranmists as a result of a timeout.
Retransmit as a result of path mtu discover, fast retransmit, or
other evernts that should trigger immidiate retransmissions got broken.
Also, since rto is doubled prior to marking of packets elegable for
retransmission, we never marked correct chunks anyway.
The fix is provide a reason for a given retransmission so that we
can mark chunks appropriately and to save the old rto value to do
comparisons against.
All regressions tests passed with this code.

...and fix a couple of bugs in the NBD, CIFS and OCFS2 socket handlers.
Looking at the sock->op->shutdown() handlers, it looks as if all of them
take a SHUT_RD/SHUT_WR/SHUT_RDWR argument instead of the
RCV_SHUTDOWN/SEND_SHUTDOWN arguments.
Add a helper, and then define the SHUT_* enum to ensure that kernel users
of shutdown() don't get confused.

The context switch code in the kernel issues a dummy stwcx. to clear the
reservation, as recommended by the architecture. However, some processors
can have issues if this stwcx to address A occurs while the reservation
is already held to a different address B. To avoid this problem, the dummy
stwcx. needs to be paired with a dummy lwarx to the same address.
This adds the dummy lwarx, and creates a cpu feature bit to indicate
which cpus are affected. Tested on mpc8641_hpcn_defconfig in
arch/powerpc; build tested in arch/ppc.

git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-virtio
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-virtio:
virtio: Force use of power-of-two for descriptor ring sizes
lguest: Fix lguest virtio-blk backend size computation
virtio: Fix used_idx wrap-around
virtio: more fallout from scatterlist changes.
virtio: fix vring_init for 64 bits

The virtio descriptor rings of size N-1 were nicely set up to be
aligned to an N-byte boundary. But as Anthony Liguori points out, the
free-running indices used by virtio require that the sizes be a power
of 2, otherwise we get problems on wrap (demonstrated with lguest).
So we replace the clever "2^n-1" scheme with a simple "align to page
boundary" scheme: this means that all virtio rings take at least two
pages, but it's safer than guessing cache alignment.

This patch fixes a typo in vring_init(). This happens to work today in lguest
because the sizeof(struct vring_desc) is 16 and struct vring contains 3
pointers and an unsigned int so on 32-bit
sizeof(struct vring_desc) == sizeof(struct vring). However, this is no longer
true on 64-bit where the bug is exposed.

This patch fixes a small memory leak. Default fib rules can be deleted by
the user if the rule does not carry FIB_RULE_PERMANENT flag, f.e. by
ip rule flush
Such a rule will not be freed as the ref-counter has 2 on start and becomes
clearly unreachable after removal.

The intent of the assertion in skb_truesize_check() is to check
for skb->truesize being decremented too much by other code,
resulting in a wraparound below zero.
The type of the right side of the comparison causes the compiler to
promote the left side to an unsigned type, despite the presence of an
explicit type cast. This defeats the check for negativity.
Ensure both sides of the comparison are a signed type to prevent the
implicit type conversion.

restore sigcontext is taking a DNA exception while restoring FP context
from the user stack, during the sigreturn. Appended patch fixes it by
doing clts() if the app doesn't touch FP during the signal handler
execution. This will stop generating a DNA, during the fxrstor in the
sigreturn.
This improves 64-bit lat_sig numbers by ~30% on my core2 platform.

This patch adds a proper prototype for migration_init() in
include/linux/sched.h
Since there's no point in always returning 0 to a caller that doesn't check
the return value it also changes the function to return void.

SMP balancing is done with IRQs disabled and can iterate the full rq.
When rqs are large this can cause large irq-latencies. Limit the nr of
iterations on each run.
This fixes a scheduling latency regression reported by the -rt folks.

Since powerpc started using CONFIG_GENERIC_CLOCKEVENTS, the
deterministic CPU accounting (CONFIG_VIRT_CPU_ACCOUNTING) has been
broken on powerpc, because we end up counting user time twice: once in
timer_interrupt() and once in update_process_times().
This fixes the problem by pulling the code in update_process_times
that updates utime and stime into a separate function called
account_process_tick. If CONFIG_VIRT_CPU_ACCOUNTING is not defined,
there is a version of account_process_tick in kernel/timer.c that
simply accounts a whole tick to either utime or stime as before. If
CONFIG_VIRT_CPU_ACCOUNTING is defined, then arch code gets to
implement account_process_tick.
This also lets us simplify the s390 code a bit; it means that the s390
timer interrupt can now call update_process_times even when
CONFIG_VIRT_CPU_ACCOUNTING is turned on, and can just implement a
suitable account_process_tick().
account_process_tick() now takes the task_struct * as an argument.
Tested both with and without CONFIG_VIRT_CPU_ACCOUNTING.

we lost the sched_min_granularity tunable to a clever optimization
that uses the sched_latency/min_granularity ratio - but the ratio
is quite unintuitive to users and can also crash the kernel if the
ratio is set to 0. So reintroduce the min_granularity tunable,
while keeping the ratio maintained internally.
no functionality changed.

Now that copy_to_user_page()/copy_from_user_page() are wired up, we
can drop the old __copy_xxx() implementations. Now that the page
colouring scheme has changed via kmap_coherent(), we can avoid the
flush in these specific helpers.

This moves copy_{to,from}_user_page() out-of-line on SH-4 and
converts for the kmap_coherent() API. Based on the MIPS
implementation.

With the kmap_coherent() API in place, this is trivial to implement,
and lets us avoid the cache flush in certain cases.

We have nothing to do here, but there are continually drivers that
fail to build without it. Stub it in.
