sys/i386/i386 pmap.c
sys/vm uma_int.h
Log:
- Significantly reduce the number of preallocated pv entries in
pmap_init(). Such a large preallocation is unnecessary and wastes
nearly eight megabytes of kernel virtual address space per gigabyte
of managed physical memory.
- Increase UMA_BOOT_PAGES by two. This enables the removal of
pmap_pv_allocf(). (Note: this function was only used during
initialization, specifically, after pmap_init() but before
pmap_init2(). During pmap_init2(), a new allocator is installed.)
