Use page->lru.next to implement the singly linked list of pages rather than

When on_each_cpu() runs the callback on other CPUs, it runs with local
interrupts disabled.  So we should run the function with local interrupts
disabled on this CPU, too.

And do the same for UP, so the callback is run in the same environment on both
UP and SMP.  (strictly it should do preempt_disable() too, but I think
local_irq_disable is sufficiently equivalent).

Also uninlines on_each_cpu().  softirq.c was the most appropriate file I could
find, but it doesn't seem to justify creating a new file.

Oh, and fix up that comment over (under?) x86's smp_call_function().  It
drives me nuts.

Have an explicit mm call to split higher order pages into individual pages.

- Don't return uninitialised stack values in case of allocation failure

- Don't bother clearing PageCompound because __GFP_COMP wasn't specified
  Increment over the pte page rather than one pte entry in
  pte_alloc_one_kernel

- Actually increment the page pointer in pte_alloc_one

Sam's tree includes a new check, which found that we're exporting strpbrk()
multiple times.

It seems that the convention is that this is exported from the arch files, so
reove the lib/string.c export.

The AES setkey routine writes 64 bytes to the E_KEY area even though
there are only 60 bytes there.  It is in fact safe since E_KEY is
immediately follwed by D_KEY which is initialised afterwards.  However,
doing this may trigger undefined behaviour and makes Coverity unhappy.

So by combining E_KEY and D_KEY into one array we sidestep this issue
altogether.

This problem was reported by Adrian Bunk.

The i386 defconfig wasn't updated for ages.

Instead of running "make oldconfig" on the old defconfig and trying to
give reasonable answers at all new options, this patch replaces it with
the one I'm using in 2.6.16-rc1.

This way, it's a .config that is confirmed to work on at least one
computer in the world.  ;-)

We only need to write an invalid tag every 16 bytes,
so taking advantage of this can save many instructions
compared to the simple memset() call we make now.

A prefetching implementation is implemented for sun4u
and a block-init store version if implemented for Niagara.

The next trick is to be able to perform an init and
a copy_tsb() in parallel when growing a TSB table.

If a grow fails, we are under memory pressure, so do not try
to grow the TSB for this address space any more.
