Branch: sys/i386/include RELENG_2_2
sys/miscfs/procfs RELENG_2_2
sys/vm RELENG_2_2
Modified: sys/i386/include vmparam.h
sys/miscfs/procfs procfs_map.c
sys/vm vm_extern.h vm_fault.c vm_glue.c vm_kern.c
vm_map.c vm_map.h vm_meter.c vm_mmap.c vm_object.c
vm_page.c vm_pageout.c vm_pageout.h vnode_pager.c
Log:
1. Fix the vm_page_zero_count accounting. This should improve the
performance of the pre-zero loop.
2. Fix madvise. It had a myriad of bugs, including the potential
for system crashes.
3. Improve vm_map handling. This is a result of work done by both
<alc@cs.rice.edu> (Alan Cox) and me. Earlier versions of the
map handling code was very unintelligent about map coalescing.
4. Support a working and closer to POSIX mlock.
5. A couple of performance enhancements that came along for the ride,
including changing certain bitfields to flags in vm_map.
6. Bring procfs up to date with respect to the changes.
This code has been carefully extracted from -current.
