fs, kmemtrace: fix fs.h's PAGE_SIZE dependency

Impact: build fix

ARM does not build due to fs.h using PAGE_SIZE but not including
asm/page.h.

(This was masked before by rcupreempt.h including percpu.h which
brought in asm/page.h indirectly.)

( A future enhancement would be to split out the simple_transaction
  facility (only two usage sites) from fs.h, into a separate
  linux/simple_transaction.h header. )
