From current testsuite results, the optimizer bugs don't appear to exist
anymore. RTH@cygnus.com did a lot of work on the Alpha ELF code generator
for GCC 3.2[.0]. A recent FreeBSD/AXP GCC bootstrap is at
http://gcc.gnu.org/ml/gcc-testresults/2002-09/msg00604.html
In this bootstraps, all gcc libraries are built with -O2 and c-torture
gives -O2 a real workout. None of the remaining failures have anything
to do with -O2 optimizer bugs.

ALQ (Asynch. Logging Queues). ALQ supports many seperate queues with
different record and buffer sizes. It opens and logs to any vnode so
it can be used with character devices as well as regular files.

According to the MII specification, the delay produced by our
reads alone are sufficient for correct operation.
This reduces the time mii_tick takes from 10ms to ~1ms here. That's
still a lot, but much better than before.

so that it is MI. Allow nfs_mountroot to return an error if the nfs_diskless
struct is not valid, rather than panicing later on. Call nfs_setup_diskless()
from nfs_mountroot if NFS_ROOT is defined, like bootpc_init(). Removed legacy
root mount support for sparc64, and enabled NFS_ROOT by default.
- Sort local variable declarations.
- Protect a hand-formatted comment from indent(1).
- Use portable casts, even though this is machine-dependant code.
- Remove extraneous blank lines.
- Remove trailing newline.
- Use sigdelset(3), not SIGDELSET(9).

constants VM_MIN_ADDRESS, VM_MAXUSER_ADDRESS, USRSTACK and PS_STRINGS.
This is mainly so that they can be variable even for the native abi, based
on different machine types. Get stack protections from the sysentvec too.
This makes it trivial to map the stack non-executable for certain abis, on
machines that support it.
TrustedBSD MAC Perforce tree. Remove unused functions
mac_biba_equal_range and mac_mls_equal_range, which determined if the
ranges in two range-enabled labels were equal.

Fix them by fixing variable names. It would be really nice if
opt_global.h was used when building modules as part of a buildkernel.
