cc3d8c35f5 There are several code sequences like 
vfs_busy(mp);
      vfs_write_suspend(mp);
which are problematic if other thread starts unmount between two
calls.  The unmount starts a write, while vfs_write_suspend() drain
writers.  On the other hand, unmount drains busy references, causing
the deadlock.

Add a flag argument to vfs_write_suspend and require the callers of it
to specify VS_SKIP_UNMOUNT flag, when the call is performed not in the
mount path, i.e. the covered vnode is not locked.  The suspension is
not attempted if VS_SKIP_UNMOUNT is specified and unmount is in
progress.

5163701c22 Nearly a complete rewrite of elf.h. 
Start with NetBSD's sys/arch/mips/include/elf_machdep.h 1.18. Remove the NetBSD
specific glue pieces (leaving mostly just relocation types).

Add in FreeBSD specific glue pieces from older versions of this file, and
move to the top of the file:

as closely as I can tell, the projects/mips branch merge was disruptive
to good history.

This should make merges easier in the future from NetBSD and vice versa.

d6fc869ebd should_yield: protect from td_swvoltick being uninitialized or too stale 
The distance between ticks and td_swvoltick should be calculated as
an unsigned number.  Previously we could end up comparing a negative
number with hogticks in which case should_yield() would give incorrect
answer.

We should probably ensure that td_swvoltick is properly initialized.

bf3c9330ba Enhancement when writing an entire block of a file. 
Merge from UFS r231313:

This change first attempts the uiomove() to the newly allocated
(and dirty) buffer and only zeros it if the uiomove() fails. The
effect is to eliminate the gratuitous zeroing of the buffer in
the usual case where the uiomove() successfully fills it.
