Bring a couple of changes from NetBSD:
queue.c (CVS Rev. 1.4. 1.5)
Fix memory leaks.
NULL does not need a cast.
grep.c (CVS Rev. 1.6)
Use the more portable getline.

code. The consensus on arch@ is that this feature might have been useful
in the distant past, but is now just unnecessary bloat.
The int_rman_activate_resource() and int_rman_deactivate_resource()
functions become trivial, so manually inline them.
The special deferred handling of RF_ACTIVE is no longer needed in
reserve_resource_bound(), so eliminate the associated code at the
end of the function.
These changes reduce the object file size by more than 500 bytes on i386.
Update the rman.9 man page to reflect the removal of the RF_TIMESHARE
feature.

code duplication with dev/fb/fbd.c, which will fixed later on.
Also improve performance of vt_blank() by making it not read from the
framebuffer unnecessarily.
This allows to clone VMs and move them between LUNs inside one storage
host without generating extra network traffic to the initiator and back,
and without being limited by network bandwidth.
LUNs participating in copy operation should have UNIQUE NAA or EUI IDs set.
For LUNs without these IDs VMWare will use traditional copy operations.
Beware: the above LUN IDs explicitly set to values non-unique from the VM
cluster point of view may cause data corruption if wrong LUN is addressed!

Improve extreme rewind import.
When doing an "extreme rewind" import ("zpool import -XF"), we attempt
to verify all data in the pool, essentially scrubbing the entire pool.
The problem is that spa_load_verify_cb() issues an unbounded number of
concurrent scrub i/os. This can lead to all of memory being used for
these zio's, wedging the system. Like normal scrub, we need to put a
cap on the number of outstanding i/os, and have the traverse thread
block when we reach this cap.
For this purpose the cap can be very large (10,000) to optimize the
elevator algorithm. Three kernel tunables have been added:
vfs.zfs.spa_load_verify_maxinflight
vfs.zfs.spa_load_verify_metadata
vfs.zfs.spa_load_verify_data
The latter two tunables controls whether metadata and/or user data
when doing extreme rewind.
Make 'zpool import -T' imply scrub.
Make zpool import -T <txg> accept hexadecimal values for the txg when
prefixed with 0x.
Skip txg's for which there is no uberblock when doing extreme rewind.
Skip reading all user data twice by skipping prefetches when doing
extreme rewinds as we do not access via the ARC.
Illumos issues:
4970 need controls on i/o issued by zpool import -XF
4971 zpool import -T should accept hex values
4972 zpool import -T implies extreme rewind, and thus a scrub
4973 spa_load_retry retries the same txg
4974 spa_load_verify() reads all data twice

- Move the code to calculate resident count into separate function.
It reduces the indent level and makes the operation of
vmmap_skip_res_cnt tunable more clear.
- Optimize the calculation of the resident page count for map entry.
Skip directly to the next lowest available index and page among the

- Restore the use of pmap_incore(9), only to verify that current
mapping is indeed superpage.
- Note the issue with the invalid pages.

instruction emulation [1].
Fix bug in emulation of opcode 0x8A where the destination is a legacy high
byte register and the guest vcpu is in 32-bit mode. Prior to this change
instead of modifying %ah, %bh, %ch or %dh the emulation would end up
modifying %spl, %bpl, %sil or %dil instead.
Add support for moffsets by treating it as a 2, 4 or 8 byte immediate value
during instruction decoding.
Fix bug in verify_gla() where the linear address computed after decoding
the instruction was not being truncated to the effective address size [2].

Previously, the "no execute" bit was being set directly in the PTE, instead
of the local variable in which the new PTE value is being constructed. So,
when the local variable was finally assigned to the PTE, the "no execute"
bit setting was lost.
