traffic.
* Create sc_mgmt_txbuf and sc_mgmt_txdesc, initialise/free them appropriately.
* Create an enum to represent buffer types in the API.
* Extend ath_getbuf() and _ath_getbuf_locked() to take the above enum.
* Right now anything sent via ic_raw_xmit() allocates via ATH_BUFTYPE_MGMT.
This may not be very useful.
* Add ATH_BUF_MGMT flag (ath_buf.bf_flags) which indicates the current buffer
is a mgmt buffer and should go back onto the mgmt free list.
* Extend 'txagg' to include debugging output for both normal and mgmt txbufs.
* When checking/clearing ATH_BUF_BUSY, do it on both TX pools.
Tested:
* STA mode, with heavy UDP injection via iperf. This filled the TX queue
however BARs were still going out successfully.
TODO:
* Initialise the mgmt buffers with ATH_BUF_MGMT and then ensure the right
type is being allocated and freed on the appropriate list. That'd save
a write operation (to bf->bf_flags) on each buffer alloc/free.
* Test on AP mode, ensure that BAR TX and probe responses go out nicely
when the main TX queue is filled (eg with paused traffic to a TID,
awaiting a BAR to complete.)

must be recalculated. The blk_check pass of suj checker explicitely marks
inodes which owned such blocks as needing block count adjustment. But
ino_adjblks() is only called by cg_trunc pass, which is performed before
blk_check. As result, the block use count for such inodes is left wrong.
This causes full fsck run after journaled run to still find inconsistencies
like 'INCORRECT BLOCK COUNT I=14557 (328 should be 0)' in phase 1.
Fix this issue by running additional adj_blk pass after blk_check, which
updates the field.

which was inadvertently caused by r236185: if SHLIBDIR is set using the
?= operator, it must be done *before* bsd.own.mk is included, otherwise
the default value is still used.
Note, bsd.lib.mk will take care of removing the copy in /usr/lib upon
installation, so no addition to ObsoleteFiles.inc is needed.

thing it was still used for was to set the "global default" password
hash. Since the stock auth.conf contained nothing but comments, the
global default was actually the first algorithm in crypt(3)'s list,
which happens to be DES; I take the fact that nobody noticed as proof
that it was not used outside of crypt(3).
The only other use in our tree was in the Kerberos support code in
in tinyware's passwd(1). I removed that code in an earlier commit;
it would not have compiled anyway, as it only supported Kerberos IV.
The auth_getval() function is now a stub that always returns NULL,
which has the same effect as a functional auth_getval() with an
empty auth.conf.

Initial support for the AMD barcelona chipsets has been available in the
gcc43 branch under GPLv2 but was not included when the Core 2 support
was brought to the system gcc.
AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10
support and made them available. Unfortunately this is still experimental
and while it can improve performance, enabling the CPUTYPE may break some
C++ ports (like clang).
Special care was taken to make sure that the patches predate the GPLv3
switch upstream.

and bmsafemap dependency structures in inodedep_lookup() and
bmsafemap_lookup() respectively. The setup of these structures must
be done while holding the soft-dependency mutex. If the inodedep is
allocated first, it may be freed in the I/O completion callback when
the mutex is released to allocate the bmsafemap. If the bmsafemap is
allocated first, it may be freed in the I/O completion callback when
the mutex is released to allocate the inodedep.
To resolve this problem, bmsafemap_lookup has had a parameter added
that allows a pre-malloc'ed bmsafemap to be passed in so that it does
not need to release the mutex to create a new bmsafemap. The
softdep_setup_inomapdep() routine pre-malloc's a bmsafemap dependency
before acquiring the mutex and starting to build the inodedep with a
call to inodedep_lookup(). The subsequent call to bmsafemap_lookup()
is passed this pre-allocated bmsafemap entry so that it need not
release the mutex if it needs to create a new one.
