thread0 used a borrowed priority it would drop down to PUSER instead of
PVM.

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.

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.

as is support for framebuffer resolutions other than 720x480. These

find the correct mount point mp and use that mp for the
subsequent vn_finished_write() call. Also, it should fail
without crashing if the mount point is being forced dismounted
because vn_start_write() will set the mp NULL via VOP_GETWRITEMOUNT().

the dependency of which was preloaded, but failed to initialize. Previously,
kernel dereferenced NULL pointer returned by modlist_lookup2(); now, when this
happens, we unload the dependent module. Since the depended_files list is
sorted in dependency order, this properly propagates, unloading modules that
depend on failed ones.
From the user point of view, this prevents the kernel from panicing when
trying to boot kernel compiled without KDTRACE_HOOKS with dtraceall_load="YES"

The macros here for generating coprocessor 0 accessors are named like:
MIPS_RDRW32_COP0
That macro would produce mips_rd_<register>() and mips_wr_<register>()
inlines to access the specified register by name from C. The problem is that
the R and the W were swapped in the macros originally; it was meant to be named
RDWR because it generated mips_rd_* and mips_wr_* functions, but was instead
spelled RDRW, which nobody should be expected to get right by anything other
than copy and paste.
It's too many consonants in a row to keep straight anyway, so just prefer e.g.:
MIPS_RW32_COP0
While here, add a missing #undef.
