2c55431721 Add a VIS-based block copy function for SPARC64 V and later, which
additionally takes advantage of the prefetch cache of these CPUs.
Unlike the uncommitted US-III version, which provide no measurable
speedup or even resulted in a slight slowdown on certain CPUs models
compared to using the US-I version with these, the SPARC64 version
actually results in a slight improvement.

Note there is still no information about 'partcode' being written to disk
(gpart bootcode -p <partcode> <disk>).

Maybe in the future all the messages printed by gpart(8) on success could be
hidden under -v?

198ec86bf9 - Update the comment in swi_vm() regarding busdma bounce buffers; it's
unlikely that support for these ever will be implemented on sparc64 as
  the IOMMUs are able to translate to up to the maximum physical address
  supported by the respective machine, bypassing the IOMMU is affected
  by hardware errata and being able to support DMA engines which cannot
  do at least 32-bit DMA does not justify the costs.
- The page zeroing in uma_small_alloc() may use the VIS-based block zero
  function so take advantage of it.

89d10571db Remove empty devfs directories automatically.
devfs_delete() now recursively removes empty parent directories unless
the DEVFS_DEL_NORECURSE flag is specified. devfs_delete() can't be
called anymore with a parent directory vnode lock held because the
possible parent directory deletion needs to lock the vnode. Thus we
unlock the parent directory vnode in devfs_remove() before calling
devfs_delete().

Call devfs_populate_vp() from devfs_symlink() and devfs_vptocnp() as now
directories can get removed.

Add a check for DE_DOOMED flag to devfs_populate_vp() because
devfs_delete() drops dm_lock before the VI_DOOMED vnode flag gets set.
This ensures that devfs_populate_vp() returns an error for directories
which are in progress of deletion.

8a3883cfb7 zfs vn_has_cached_data: take into account v_object->cache != NULL
This mirrors code in tmpfs.
This changge shouldn't affect much read path, it may cause unnecessary
vm_page_lookup calls in the case where v_object has no active or inactive
pages but has some cache pages.  I believe this situation to be non-essential.

In write path this change should allow us to properly detect the above
case and free a cache page when we write to a range that corresponds to it.
If this situation is undetected then we could have a discrepancy between
data in page cache and in ARC or on disk.

This change allows us to re-enable vn_has_cached_data() check in zfs_write.

NOTE: strictly speaking resident_page_count and cache fields of v_object
should be exmined under VM_OBJECT_LOCK, but for this particular usage
we may get away with it.

c183b9c683 Change the default MSS for IPv4 and IPv6 TCP connections from an
artificial power-of-2 rounded number to their real values specified
in RFC879 and RFC2460.

From the history and existing comments it appears that the rounded
numbers were intended to be advantageous for the kernel and mbuf
system.  However this hasn't been the case at for at least a long
time.  The mbuf clusters used in tcp_output() have enough space
to hold the larger real value for the default MSS for both IPv4 and
IPv6.  Note that the default MSS is only used when path MTU discovery
is disabled.

Update and expand related comments.

d948155465 sys/pcpu.h: remove a workaround for a fixed ld bug
The workaround was incorrectly documented as having something to do with
set_pcpu section's progbits, but in fact it was for incorrect placement
of __start_set_pcpu because of the bug in ld.
The bug was fixed in r210245, see commit message for details.

A side-effect of the workaround was that a zero-size set_pcpu section was
produced for modules, source code of which included pcpu.h but didn't
actually define any dynamic per-cpu variables.
This commit should remove the side-effect.

The same workaround is present sys/net/vnet.h, has an analogous side-effect
and can be removed as well.

An UPDATING entry that warns about a need for recent ld is following.

c895b6e6ee Port r212559 to mips.
Do not explicitly enable interrupts in smp_init_secondary() because it
renders any spinlock protected code after that point to run with
interrupts enabled. This is because the processor is executing in the
context of idlethread whose 'md_spinlock_count' is already set to 1.

Instead just let sched_throw() re-enable interrupts when it releases
the spinlock.
