create demand-paging mapping in case of MAP_SHARED
...
On current McKernel, only mappings for demand paging can be shared.
Therefore, if MAP_SHARED and MAP_ANONYMOUS are specified and
anon_on_demand is disabled, then mmap(2) should create a mapping which
is for demand paging and is entirely populated with physical pages.

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.
