sys/vm vm_map.c uma_core.c uma_int.h uma.h
sys/i386/i386 pmap.c
Log:
- Introduce the new M_NOVM option which tells uma to only check the currently
allocated slabs and bucket caches for free items. It will not go ask the vm
for pages. This differs from M_NOWAIT in that it not only doesn't block, it
doesn't even ask.
- Add a new zcreate option ZONE_VM, that sets the BUCKETCACHE zflag. This
tells uma that it should only allocate buckets out of the bucket cache, and
not from the VM. It does this by using the M_NOVM option to zalloc when
getting a new bucket. This is so that the VM doesn't recursively enter
itself while trying to allocate buckets for vm_map_entry zones. If there
are already allocated buckets when we get here we'll still use them but
otherwise we'll skip it.
- Use the ZONE_VM flag on vm map entries and pv entries on x86.
