calendar(1) can have input in various encoding, specifying
LANG=<locale_name> to enable calendar(1) to determine which one to use.
The problem is the content of the calendar itself is exposed as is making it
unreadable in many cases. For example french calendar which is encoded
ISO8859-1 is rendered badly in a fr_FR.UTF-8 environment.
Using iconv allows to solve this issue.
This will also allow to keep only 1 encoding in base for those files without
breaking user existing setup

When I added support for the standard loader(8) disk0s2a: type formats,
the parsing of legacy format was broken because it also contains a colon,
but it comes before the slice and partition. That would cause disk_parsedev()
to return success with the slice and partition set to wildcard values.
This change examines the string first, and if it contains spaces, dots, or
a colon at any position other than the end, it must be a legacy-format
string and we don't even try to use disk_parsedev() on it.

Take a pass through fixing some of the most egregious whitespace issues in
fs/fuse. Also fix some style(9) warts while here. Not 100% cleaned up, but
somewhat less painful to look at and edit.
No functional change.
idle_td is dereferenced without thread-locking it to make its contents is
invariant, and was accessed without telling the compiler that its contents
is invariant. Some compilers optimized accesses to the supposedly invariant
contents by moving the critical checks for changes outside of the loop that
waits for changes. Fix this using atomic ops.
This bug only showed up for the following configuration: a Turion2
system, amd64 kernels, compiled by gcc, and SCHED_4BSD. clang fails
to do the optimization with all CFLAGS that I tried, because it doesn't
fully optimize the '__asm __volatile' for cpu_spinwait() although this
asm has no memory clobber. gcc only does the optimization with most
CFLAGS. I mostly used -Os with all compilers. i386 works because gcc
-m32 -Os only moves 1 or the 2 accesses outside of the loop.
Non-Turion2 systems and SCHED_ULE worked due to different timing (when
all APs start before the BP checks them outside of the loop).

The flag for the driver capability of supporting the fix is independent

I forget to preserve it when resetting the terminal.
a vdev that has the same name as the one stored in metadata and that has
all VDEV labels in place. If it cannot find a GEOM provider with the given
name and all VDEV labels it will scan all GEOM providers for the best match
(the most VDEV labels available), but here the name is ignored.
In case the ZFS pool is created, eg. using GPT partition label:
# zpool create tank /dev/gpt/tank
everything works, and on every import ZFS will pick /dev/gpt/tank and
not /dev/da0p4.
The problem occurs when da0p4 is extended and ZFS is unable to find all
VDEV labels in /dev/gpt/tank anymore (the VDEV labels stored at the end
of the partition are now somewhere else). In this case it will scan all
GEOM providers and will pick the first one with the best match, ie. da0p4.
Fix this problem by checking the VDEV/provider name even if we get the same
match. If the name is the same as the one we have in pool's metadata, prefer
this GEOM provider.

In short, the prior code was far too simplistic when it came to calling recv(2)
and failed intermittently (or in the case of Jenkins, deterministically).
Handle short recv(2)s by checking the return code and incrementing the window
into the buffer by the number of received bytes. If the number of received
bytes <= 0, then bail out of the loop, and test the total number of received
bytes vs the expected number of bytes sent for equality, and base whether or
not the test passes/fails on that fact.
Remove the expected failure, now that the hdtr testcases deterministically pass
on my host after this change [1].

Right now it's possible to invoke the REP escape sequence with a maximum
of tens of millions of iterations. In practice, there is never any need
to do this. Calling it more frequently than the number of cells in the
terminal hardly makes any sense. By placing a limit on it, we can
prevent users from exhausting resources in inside the terminal emulator.
As support for this escape sequence is not present in any of the stable
branches, there is no need to MFC.

The DIOCGETZONE ioctl can be used to fetch the zone list of an SMR
drive, and the caller specifies the number of entries it wants to fetch.
Clamp the caller's request to a sane limit so that a user cannot attempt
large allocations. Callers already need to invoke the ioctl multiple
times to fetch the full list in general, so there's no harm in limiting
the number of entries returned.
Fix style while here.

EVFILT_WRITE knotes for pipes live on the knlist for the other end of the
pipe. Since they do not hold a reference on the corresponding file
structure, they may be removed from the knlist by pipeclose() while still
remaining active. In this case, there is no knlist lock acquired before
filt_pipewrite() is called, so the assertion fails.
Fix the problem by first checking whether that end of the pipe has been
closed. These checks are memory safe since the knote holds a reference
on one end of the pipe, and the pipe structure is not freed until both
ends are closed. The checks are not racy since PIPE_EOF is never cleared
after being set, and pipe_present is never set back to PIPE_ACTIVE after
pipeclose() has been called.

The code first tries to parse the variable in this format using the

legacy format that has been supported by ubldr for years.
In addition to 'disk', all the valid uboot device names can also be used:
mmc, sata, usb, ide, scsi. The 'disk' device serves as an alias for all
