mutexes, which offers lower overhead on both UP and SMP. When allocating
from or freeing to the per-cpu cache, without INVARIANTS enabled, we now
no longer perform any mutex operations, which offers a 1%-3% performance
improvement in a variety of micro-benchmarks. We rely on critical
sections to prevent (a) preemption resulting in reentrant access to UMA on
a single CPU, and (b) migration of the thread during access. In the event
we need to go back to the zone for a new bucket, we release the critical
section to acquire the global zone mutex, and must re-acquire the critical
section and re-evaluate which cache we are accessing in case migration has
occured, or circumstances have changed in the current cache.
Per-CPU cache statistics are now gathered lock-free by the sysctl, which
can result in small races in statistics reporting for caches.

sys.mk which does not switch on these warnings, so make will be silent.
They can be switch on on the command line with the -x option to make.
This has been tested by building RELENG_5_4 on CURRENT.

Use getgrouplist(3) for the case when an user was specified,
and getgroups(2) when no user was given.
That reverts to the expected behaviour and makes it easy to
implement an option later to force using getgrouplist(3).

ranges decoded by the bridge. When allocation for VGA addresses is
attempted, check that the bridge has the VGA Enable bit set before
allowing it.
As such, newbusified VGA drivers can allocate their resources when
the VGA adapter is behind a PCI-to-PCI bridge.

NGROUPS groups. getgrouplist(3) may put a duplicate group
id into the passed array (it sets [0] and [1] to the value
of the gid argument), but id_print() sorts them out.
Showing the ids of both an user given by an argument to `id',
and the current user, is now handled in a single function.
Displaying the current user's ids was inaccurate because
getgroups(2) had been used. getgroups(2) returns the current
kernel state of a user's groups, which may not always be
correct if /etc/group was recently changed.
