e780324662 Remove redundant critical_enter/exit() calls. The block of code delimited
by these calls is now protected by a spin mutex (obscured within the

428cdf0280 Move some code around and rename a couple variables; no functional changes.
The static atrtc_set() function was called only from clock_settime(), so
just move its contents entirely into clock_settime() and delete atrtc_set().

Rename the struct bcd_clocktime variables from 'ct' to 'bct'.  I had
originally wanted to emphasize how identical the clocktime and bcd_clocktime
structs were, but things evolved to the point where the structs are not at
all identical anymore, so now emphasizing the difference seems better.

e9a3a1b13c Fix a bug related to fast retransmissions.
When processing a SACK advancing the cumtsn-ack in fast recovery,
increment the miss-indications for all TSN's reported as missing.

Thanks to Fabian Ising for finding the bug and to Timo Voelker
for provinding a fix.

This fix moves also CMT related initialisation of some variables

I need these tools in order to install the crossbuilt FreeBSD and create a
disk image. Linux does not have a st_flags in struct stat so unfortunately
I need a bunch of ugly ifdefs. The resulting binaries allow me to
sucessfully install a MIPS64 world and create a disk-image that boots.

da67e6e62c kldxref: handle modules with md_cval at the end of allocated sections
Attempting to retrieve an md_cval string from a kernel module with
kldxref would throw a offset error for modules created using lld, since
this value would be placed at the end of all allocated sections.

Add an ef_read_seg_string method to the ef interface, to allow reading
strings of varying size without attempting to read beyond the segment's
bounds.

469759f8e4 Exit fsck_ffs with non-zero status when file system is not repaired.
When the fsck_ffs program cannot fully repair a file system, it will
output the message PLEASE RERUN FSCK. However, it does not exit with a
non-zero status in this case (contradicting the man page claim that it
"exits with 0 on success, and >0 if an error occurs."  The fsck
rc-script (when running "fsck -y") tests the status from fsck (which
passes along the exit status from fsck_ffs) and issues a "stop_boot"
if the status fails. However, this is not effective since fsck_ffs can
return zero even on (some) errors. Effectively, it is left to a later
step in the boot process when the file systems are mounted to detect
the still-unclean file system and stop the boot.

This change modifies fsck_ffs so that when it cannot fully repair the
file system and issues the PLEASE RERUN FSCK message it also exits
with a non-zero status.

While here, the fsck_ffs man page has also been updated to document
the failing exit status codes used by fsck_ffs. Previously, only exit
status 7 was documented. Some of these exit statuses are tested for in
the fsck rc-script, so they are clearly depended upon and deserve
documentation.
