Also remove some TSO related cruft.
Add some watchdog_time setting that was missing, thanks
to Mikolaj Golub for pointing that out.
subsequently in pmap_pinit() with the following signature:

This bug was uncovered by the changes made to vm_map.c in r206140.
This causes a panic in vm_thread_dispose() when it tries to add this kstack
to the kstack cache. This happens only when 'td_kstack' is not (PAGE_SIZE * 2)
bytes aligned and we have unmapped the page at that address in cpu_thread_alloc.

The sequence number is used as the name of a sysctl node,
under which we add the MCA records using the CPU id as the
leaf name.
Add the hw.mca.inject sysctl to provide a way to inject
MC errors and trigger machine checks.

useful it will be, but we really need to be keying off something other
than MACHINE for this anyway since on arm and mips we have lots of
these running around (one for each SoC family)...
instead of causing erratic behavior. Currently make_dev(9) can't fail, so
there is no way to report an error to make_dev(9) callers.
- Disallow using "." and ".." in device path names. It didn't work previously
but now it is reported rather than panicing.
- Treat multiple sequential slashes as single in device path names.

DTYPE_VNODE.
Only acquire locks for O_EXLOCK/O_SHLOCK if file type is still vnode,
since we allow for fcntl(2) to process with advisory locks for
DTYPE_VNODE only. Another reason is that all fo_close() routines need to
check and release locks otherwise.
For O_TRUNC, call fo_truncate() instead of truncating the vnode.

scheduler, gsched_rr, which gives very nice performance improvements
in presence of competing random access patterns.

and presented at BSDCan 2009. You can find details in the

Current versions pass this test trivially by never importing PWD, but I plan
to change sh to import PWD if it is an absolute pathname for the current
directory, possibly containing symlinks.
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases tininess is detected
before rounding therefore rounding up to the smallest normalized number
should set the underflow flag. This change is needed for using SoftFloat
on sparc64 for reference purposes.

Previously, this would always report an error because the
exclusion prevented the entry from matching the inclusion.
Also, tar is now more reluctant to report unmatched inclusions.
Previously, "tar x file1 'file*'" against an archive that contained a
single entry "file1" would match file1 and then report an error for
the second pattern because it wasn't matched. It now considers both
inclusions to be matched and reports no error.
