commit 3919ced024a76c74c494480a2ec2188cce7c06aa
Author: Matthew Dillon <dillon@apollo.backplane.com>
Date: Sun Dec 13 12:19:30 2009 -0800
kernel - Move MP lock inward, plus misc other stuff
* Remove the MPSAFE flag from the syscalls.master file. All system calls
are now called without the MP lock held and will acquire the MP lock if
necessary.
* Shift the MP lock inward. Try to leave most copyin/copyout operations
outside the MP lock. Reorder some of the copyouts in the linux emulation
code to suit.
Kernel resource operations are MP safe.
Process ucred access is now outside the MP lock but not quite MP safe
yet (will be fixed in a followup).
* Remove unnecessary KKASSERT(p) calls left over from the time before
system calls where prefixed with sys_*
* Fix a bunch of cases in the linux emulation code when setting groups
where the ngrp range check is incorrect.
