328175547f Revert "fix REQ-37: remap_one_page: remove to check page size" 
This reverts commit 6790126a23.

- reverted commit should remove a 'pgsize' check in remap_one_page()
  instead of a 'pgsize' check in pte_make_fileoff().
- In IA-32e, PTE format varies with page size. Therefore 'pgsize'
  parameter of pte_make_fileoff() is preferable.

9ba40dc0ff schedule(): hold runq lock for the entire duration of context switching 
releasing the runq lock after loading page tables but before the actual
context switch can leave execution in an inconsistent if the current
process is descheduled from an IRQ between these two steps.
this patch holds the runq lock with IRQs disabled and makes the context
switch a single atomic operation.
