PAGE_SIZE isn't even always defined at this point,
which makes us test undefined preprocessor symbols.

It so happens that the test works in that case,
but since the test is a bit pointless in the first
place...

some rather subtle C type expansion rules.

This makes sparse happier.

This helps reduce sparse noise.

When trying to spddelete individual entries using setkey, spddelete always 
fails.  The culprit is in net/af_key.c; spdadd sets the family field of the 
selector when creating an entry, but spddelete doesn't when building a 
selector to match for xfrm_policy_bysel.  Trivial fix is to have spddelete 
set the family field in the selector in same way spdadd does.

helper function to write-back the dirty and accessed bits from
ptep_establish().

Right now this defaults to the same old "set_pte()" that we've
always done, except for x86 where we now fix the (unlikely)
race in updating accessed bits and dropping a concurrent dirty
bit.

preparation for pte update race fix.

This does not actually use the information yet, but
the next few patches will start to put it to some
good use.

Fix over long nodemask clearing in get_mem_policy() by using the
right size for the node mask.

In xfrm_state_find, the larval state never actually matures with
Openswan so it only ever gets deleted by the timer which means
that the time crash can't happen :)  It becomes a (possible) memory
leak instead.

Even with a 16kB stack, we have been seeing stack overflows on PPC64
under stress.  This patch implements separate per-cpu stacks for
processing interrupts and softirqs, along the lines of the
CONFIG_4KSTACKS stuff on x86.  At the moment the stacks are still 16kB
but I hope we can reduce that to 8kB in future.  (Gcc is capable of
adding instructions to the function prolog to check the stack pointer
whenever it moves it downwards, and I want to use that when I try
using 8kB stacks so I can be confident that we aren't overflowing the
stack.)

This patch, from Venkatesh Pallipadi, changes x86 IO-APICs to use fixed
interrupt delivery instead of lowest priority to support larger number
of CPUs.  Only bigsmp is affected by this cleanup.

We can avoid the local_irq_enable() in sched_yield() because schedule()

Currently the ACPI binding script in the Laptop Mode doc always says "20
seconds" and "2 hours" for the timeouts it uses.  This is incorrect if the
user changed the config values, so we print something more general.

PMD_SIZE is not a compile-time constant on sparc.  Use min() in there so
that the cluster size will be evaluated at runtime if the architecture
insists on doing that.

It's initialising slot 24 in two places.  Gerd Knorr <kraxel@bytesex.org> says
"This one should be 23.".
