Accomplish this by allocating space for it in __svc_xports and allowing
it to be registered. The failure to allocate space was causing an
out-of-bounds read in svc_getreq_common(). The failure to register
caused PR 211804.
The bug was found with CHERI bounds checking.

camcontrol timestamp -s would somtimes fail due to stack garbage. Zero out
the timestamp parameters to fix it.
Fix another nearby bug, and update the man page.
sbin/camcontrol/timestamp.c:
In set_timestamp(), bzero ts_p prior to creating the timestamp.
Previously stack garbage could cause some tape drives to reject the
timestamp.
In set_timestamp(), check for failures from strptime().
sbin/camcontrol/camcontrol.8:
Add the time argument to the -T option to camcontrol timestamp -s
in the long description.
Change the time/date format used in the camcontrol timestamp
example to RFC 2822 format. This fixes a time zone issue with the
original example by specifying the time zone as -0600. Otherwise,
the time zone seems to default to standard time in the current
locale, which makes the time, when reported back from the drive,
1 hour off from the intended setting. This also fixes a duplicate
day of the week ("Wednesday Wed") in the previous example.

The current reboot command in efi/loader/main.c is passing extra data with
ResetSystem, however, UEFI spec 2.6, page 265 does state:
"ResetData is only valid if ResetStatus is something other than EFI_SUCCESS
unless the ResetType is EfiResetPlatformSpecific where a minimum amount of
ResetData is always required."
Therefore we should use DataSize 0 and ResetData NULL - those are two last
arguments for the call.

Do not retest for the found semaphore after the loop to look it up.
Instead, handle both cases of last and non-last close simultaneously,
which allows to consolidate the list unlock and successful return.

r316647 corrected the build of tblgen and libllvm as dependencies for
LLD so undo the temporary seat-belt.
We still want to extend the build infrastructure to automatically detect
the case where the host LLD can be used instead of building a bootstrap
LLD, and likely extend libllvmminimal to meet LLD's needs for cases
where the build includes LLD but not Clang.

cannot access the GLOBAL2 register directly.
Despite the comment in code (which was misleading), the indirect access is
only used to read the switch CONFIG data from the scrap register and not
for the GLOBAL2 access.
Use the dsa data to define when the switch is in the Multi Chip Addressing
Mode (a even address different than zero).
While here fix a typo.

Long ago, sh used to have its own optimized and restricted string formatting
implementation, which the printf builtin had to bypass via asprintf() to a
temporary buffer. Since sh has used libc's string formatting implementation
for a long time, remove the workaround.
Add a check to keep printf %c '' working the same way (output nothing);
POSIX allows both outputting nothing and outputting a NUL byte.
Also, this change avoids silently discarding format directives for whose
output asprintf() cannot allocate memory.
This patch allows the MTU stored in the hostcache to be used as an
initial value for SCTP paths. When an ICMP PTB message is received,
store the MTU in the hostcache.

The code specified the length of a layout as INT64_MAX instead of
UINT64_MAX. This could result in getting a layout for less than the
full file for extremely large files. Although having little practical
effect, this patch corrects this in the code.

In exceptional circumstances, an MCA exception will trigger when the
freelist is exhausted. In such a case, no error will be logged on the list
and 'mca_count' will not be incremented.
Prior to this patch, all CPUs that received the exception would spin
forever.
With this change, the CPU that detects the error but finds the freelist
empty will proceed to panic the machine, ending the deadlock.
A follow-up to r260457.
