Fix lc_lock/lc_unlock() support for rmlocks held in shared mode. With
current lock classes KPI it was really difficult because there was no
way to pass an rmtracker object to the lock/unlock routines. In order
to accomplish the task, modify the aforementioned functions so that
they can return (or pass as argument) an uinptr_t, which is in the rm
case used to hold a pointer to struct rm_priotracker for current

When updating the map of dirty extents, most recently used extents are
kept dirty to reduce the number of on-disk metadata updates. The
sequence of operations is:
1) acquire the activemap lock;
2) update in-memory map;
3) if the list of keepdirty extents is changed, update on-disk metadata;
4) release the lock.
On-disk updates are not frequent in comparison with in-memory updates,
while require much more time. So situations are possible when one
thread is updating on-disk metadata and another one is waiting for the
activemap lock just to update the in-memory map.
Improve this by introducing additional, on-disk map lock: when
in-memory map is updated and it is detected that the on-disk map needs
update too, the on-disk map lock is acquired and the on-memory lock is
released before flushing the map.

send the signal, but before it sends the second thread inserts
too. When the first sends the signal only one of the waiting threads

Disallow cap_enter() in freebsd32 compatibility mode.

call sys_exit()). Affected binaries include dhclient and uniq. The latter's
crashes cause obscure build failures.
This commit makes freebsd32 cap_enter() fail with [ENOSYS], as if capability
mode was not compiled in. Applications deal with this by doing their work

share/i18n: Fix installworld with read-only obj.
Since iconv was enabled (r254273, August 13), it has been impossible to
installworld using a read-only obj tree. This is common with NFS. Parts of
share/i18n unconditionally rebuild files like mapper.dir during
installation.
This patch ensures the files like mapper.dir are not rewritten with the same
contents.

Merge in support for PAPR-compliant (Power Architecture Platform
