153344e7d3 On amd64 and i386, force assembler to mark objects compiled from the
assembler source for libcompiler_rt as not needed executable stack. This
is done with a hammer instead of properly marking each assembly file
with section .note.GNU-stack to avoid modifying contributed source.

fd05807822 - Properly initialize the base priority (td_base_pri) of thread0 to PVM
to match the desired priority in td_priority.  Otherwise the first time
  thread0 used a borrowed priority it would drop down to PUSER instead of
  PVM.
- Explicitly initialize the starting priority of new kprocs to PVM to
  avoid inheriting some random priority from thread0.

22d19207e9 - Move sched_fork() later in fork() after the various sections of the new
thread and proc have been copied and zeroed from the old thread and
  proc.  Otherwise attempts to modify thread or process data in sched_fork()
  could be undone.
- Don't copy td_{base,}_user_pri from the old thread to the new thread in
  sched_fork_thread() in ULE.  This is already done courtesy the bcopy()
  of the thread copy region.
- Always initialize the real priority (td_priority) of new threads to the
  new thread's base priority (td_base_pri) to avoid bogusly inheriting a
  borrowed priority from the parent thread.

a8f4344f08 - Restore dropping the priority of syncer down to PPAUSE when it is idle.
This was lost when it was converted to using a condition variable instead
  of lbolt.
- Drop the priority of flowtable down to PPAUSE when it is idle as well
  since it is a similar background task.

574fe75809 tests: sort & fix includes, remove -include from CFLAGS of acct tests
- Sort the includes of pack.c, moving sys/*.h files near the top.
- Add a couple of missing #include lines, and remove the need for
  custom -include options in the CFLAGS of the test Makefile.
- Remove the ad-hoc 'all' target, but keep its 'regress' bits for
  testing.
- Convert the ad-hoc 'clean' target to proper CLEANFILES stuff,
  so that the normal bsd.prog.mk machinery can clean up.
- Use `make -V .OBJDIR' to detect the place where 'pack' lives,
  so that regress.t works both with and without 'make obj'.

8974bc2f3a Since the VFS_LOCK_GIANT() code in the experimental NFS
server is broken and the major file systems are now all
mpsafe, modify the server so that it will only export
mpsafe file systems. This was discussed on freebsd-fs@
and removes a fair bit of crufty code.

03479763b2 Import support for the Sony Playstation 3 using the OtherOS feature
available on firmwares 3.15 and earlier.

Caveats: Support for the internal SATA controller is currently missing,
as is support for framebuffer resolutions other than 720x480. These
deficiencies will be remedied soon.

Special thanks to Peter Grehan for providing the hardware that made this
port possible, and thanks to Geoff Levand of Sony Computer Entertainment
for advice on the LV1 hypervisor.
