o For traps, the cr.iip register points to the next instruction to
execute on interrupt return (modulo slot). Since we need to get
the bundle of the instruction that caused the FP fault/trap, make
sure we fetch the previous bundle if the next instruction is in
fact the first in a bundle.
o When we call the FPSWA handler, we need to tell it whether it's
a trap or a fault (first argument). This was hardcoded to mean a
fault.
Also, for FP faults, when a fault is converted to a trap, adjust the
cr.iip and cr.ipsr registers to point to the next instruction. This
makes sure that the SIGFPE handler gets a consistent state.
This results in no functional change, aside from fixing a data
corruption bug on LP64 platforms. The code here could still use a
significant amount of cleanup.

to renew a lease, contact the dhcp-server directly instead of using
INADDR_BROADCAST all the time. This should fix some brain-dead dhcp
server implementations which give you all the time a new IP if the
lease has not yet expired.
Instead of using ICMP to check if the server is alive, we just check
the return value of sendto() and additionally have a timeout there.
o Simplify the logic by removing a lot of unnecesary nesting
o Reduce the amount of local variables
o Zero-out the allocated structure and get rid of
all the unnecessary setting to 0 and NULL;
Refactor _pthread_mutex_destroy
o Simplify the logic by removing a lot of unnecesary nesting
o No need to check pointer that the mutex attributes points
to. Checking passed in pointer is enough.
a list in the thread structure to keep track of the locks and
how many times they have been locked. This list is checked
on every lock and unlock. The traversal through the list is
O(n). Most applications don't hold so many locks at once that
this will become a problem. However, if it does become a problem
it might be a good idea to review this once libthr is
off probation and in the optimization cycle.
This fixes:
o deadlock when a thread tries to recursively acquire a
read lock when a writer is waiting on the lock.
o a thread could previously successfully unlock a lock it did not own
o deadlock when a thread tries to acquire a write lock on
a lock it already owns for reading or writing [ this is admittedly
not required by POSIX, but is nice to have ]
It is required to check /etc/rc.d/ldconfig before use, because
${CHROOT} sandbox is sometimes 4.x world. If /etc/rc.d/ldconfig
is not there, run ldconfig(8) directly.

- Update and improve the documentation for %[aA]
o Like %[eE], %[aA] may round the result if a precision is specified.
o Grammar police: Fix a split infinitive.
o The FreeBSD implementation does better than the minimum required
by C99 (literal translation of the mantissa). The digit before
the hexadecimal-point is never 0 unless the number itself is 0.
o Clarify that the exponent field represents a decimal exponent of 2.
o Discuss the fact that multiple valid representations are possible.
o Remove the entry in the BUGS section claiming that %[aA] is not
implemented.
- Remove the entry in the BUGS section claiming that the ' flag for
printing thousands separators is unimplemented for floating-point.
- Remove the entry in the BUGS section claiming that the L modifier
reduces the precision to "double" before conversion.
While here, disable some of the long double tests on i386, since
FreeBSD/i386 is the only port that doesn't evaluate long doubles in
their full precision (due to constant folding bugs in gcc).

rev.1.1040. It is a miscellaneous isa+pci driver, but came back
described as a pci-only driver and placed in an i4b pci subsection
after its migration to /sys/conf/NOTES. Put it back where it used to
be, fully unsorted in the `Miscellaneous hardware' section. Reduced
nearby disorder in this section by moving configuration of the digi
driver to where it was for the old digiboard drivers, so that the
order at least matches the order in the table of contents.
- references to removed math emulators for NPX_DEBUG
- header for the null set of mandatory devices
- reference to the removed (and bogus when it existed) sysctl
kern.timecounter.method.
FIxed some nearby disorder (descriptions of CPU_BLUELIGHTNING_3X,
CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_CMPXCHG, CPU_DISABLE_SSE,
CPU_ELAN_XTAL and CPU_SOEKRIS, and options for all of these except
CPU_DIRECT_MAPPED_CACHE).

This includes specifying field types, starting descriptions
with a capital letter, and ending them with a full stop.
Improve the language a bit, as well.
problem with using taskqueue_swi is that some of the things we defer
into threads might block for up to several seconds. This is an unfriendly
thing to do to taskqueue_swi, since it is assumed the taskqueue threads
will execute fairly quickly once a task is submitted. Reorganized the
locking in if_ndis.c in the process.
Cleaned up ndis_write_cfg() and ndis_decode_parm() a little.
about the location of each program's source.
This update optimizes the build a bit by giving that
information to crunchgen rather than asking crunchgen
to do a directory search to locate sources.

GCC 3.3 -O2 produces correct code on Alpha. However, note that FreeBSD
has alias bugs that make -O2 produce bad code on all(most?) platforms.
Also don't tell people we don't want -O2 related bug reports, we do -- if
they contain patches.
a new function dup_shell() to replace ok_shell() and make it unconditionnally
strdup() its result to make the caller's code simplier. Change ok_shell() to
just return an integer value suitable for tests (it was used mainly for that
purpose). Do not use strdup() in the caller's code but rely on dup_shell()
that will do the job for us.
