Some laptops don't like jumping from (for eg) 800MHz->1200MHz, but
will happily go from 800->1000->1200. The problem is caused by us
changing the FID and the VID at the same time. The spec says we have
to change them seperately. This actually buys us something extra anyway,
as we can now set the FID lazily as well as the VID.

This fixes a mismatch in declaration between "irport_interrupt" in the
header files (returning void) and in the definition (returning
irqreturn_t).

request_irq requires a handler that returns irqreturn_t,
so mm_interrupt now returns the appropriate value

This fixes a problem with drivers that have request on the stack for
some operations, like IDE.  If we wake before releasing the request, the
stack may have already disappeared beneath us when the rest of
end_that_request_last() is run.

Fix by making sure the completion is done _last_.

# pci-io-mem-size-defines

# Rename the IOP321_PCI_WINDOW_SIZE #defines to use

of Intel CPU optimizations. From Andi Kleen.

This implements automatic code patching of memory barriers based
on the CPU capabilities. Normally lock ; addl $0,(%esp) barriers
are used, but these are a bit slow on the Pentium 4.

Linus proposed this a few weeks ago after the support for SSE1/SSE2
barriers was introduced. I now got around to implement it.

The main advantage is that it allows distributors to ship less binary
kernels but still get fast kernels. In particular it avoids the
need of a special Pentium 4 kernel.

The patching code is quite generic and could be used to patch
other instructions (like prefetches or specific other critical
instructions) too.
Thanks to Rusty's in kernel loader it also works seamlessly for modules.

The patching is done before other CPUs start to avoid potential
erratas with self modifying code on SMP systems. It makes no
attempt to automatically handle assymetric systems (an secondary
CPU having less capabilities than the boot CPU). In this
case just boot with "noreplacement"

The VMA merging code can merge vmas which have a ->vm_ops->close() handler.
But this means that per-VMA resources in one of the merged VMAs will not be
freed.

Fix that up by just refusing to merge any VMA's which look "complex": they
have special flags set or they have a ->close handler.

Here is a trivial fix for task_prio() in the case MAX_RT_PRIO !=
MAX_USER_RT_PRIO.  In this case, all priorities are skewed by
(MAX_RT_PRIO - MAX_USER_RT_PRIO).

The fix is to subtract the full MAX_RT_PRIO value from p->prio, not just
MAX_USER_RT_PRIO.  This makes sense, as the full priority range is
unrelated to the maximum user value.  Only the real maximum RT value
matters.

This has been in Andrew's tree for awhile, with no issue.  Also, Ingo
acked it.

Ok, now that most drivers have been converted to the new
irqreturn_t, we can remove the fascist type-checks and just
use a regular integer type which has a simpler calling
convention.
