This patch cleans up needless includes of asm/pgalloc.h from the arch/i386/
subtree.  Compile tested on x86_pc SMP.

[I also tried VISWS + SMP without PM doesn't build in smpboot.c,
 though I don't believe its caused by this patch.  With PM, fails
 to link complaining maxcpus is undefined.  Therefore, I presume
 VISWS + SMP is an invalid configuration.]

This patch is part of a larger patch aiming towards getting the include of
asm/pgtable.h out of linux/mm.h, so that asm/pgtable.h can sanely get at
things like mm_struct and friends.

I suggest testing in -mm for a while to ensure there aren't any hidden arch
issues.
