Modified files:
sys/uvm : uvm_extern.h uvm_page.c uvm_pmemrange.c
uvmexp.h
Log message:
Turn uvm_pagealloc() mp-safe by checking uvmexp global with pageqlock held.
Use a new flag, UVM_PLA_USERESERVE, to tell uvm_pmr_getpages() that using
kernel reserved pages is allowed.
Merge duplicated checks waking the pagedaemon to uvm_pmr_getpages().
Add two more pages to the amount reserved for the kernel to compensate the
fact that the pagedaemon may now consume an additional page.
Document locking of some uvmexp fields.
