are in the filesystem from the locate database. By default, exclude
".zfs" directories, as users who who have set snapdir=visible and are
taking frequent snapshots most likely do not want the snapshots
included in the locate database.
concurrency bug. Since all SLB/SR entries were invalidated during an
exception, a decrementer exception could cause the user segment to be
invalidated during a copyin()/copyout() without a thread switch that
would cause it to be restored from the PCB, potentially causing the
operation to continue on invalid memory. This is now handled by explicit
restoration of segment 12 from the PCB on 32-bit systems and a check in
the Data Segment Exception handler on 64-bit.
While here, cause copyin()/copyout() to check whether the requested
user segment is already installed, saving some pipeline flushes, and
fix the synchronization primitives around the mtsr and slbmte
instructions to prevent accessing stale segments.

This will help to run-time detect and conditionally handle specific
optionas of either feature in user space (i.e. in libipsec).

not able to trigger the issue with sample boards, some users seems
to suffer from freeze/lockup when system is booted without UTP cable
plugged in. I'm not sure whether this is BIOS issue or controller
bug. This change fixes AR8132 lockup issue seen on EEE PC.

These do something else in ksh: name=(...) is an array or compound variable
assignment and the others are extended patterns.
This is the last patch of the ones tested in the exp run.

Apart from detecting breakage earlier or at all, this also fixes a segfault
in the testsuite. The "handling" of the breakage left an invalid internal
representation in some cases.
Examples:
echo a; do echo b
echo `) echo a`
echo `date; do do do`

was incorrect as further down the road cons_probe() calls malloc() so the
former can't be called before init_heap() has succeed. Instead just exit
to the firmware in case init_heap() fails like OF_init() does when hitting
a problem as we're then likely running in a very broken environment where
hardly anything can be trusted to work.
subevalvar() incorrectly assumed that CTLESC bytes were present iff the
expansion was quoted. However, they are present iff various processing such
as word splitting is to be done later on.
Example:
v=@$e@$e@$e@
y="${v##*"$e"}"
echo "$y"
failed if $e contained the magic CTLESC byte.

extra MACHINE_ARCH symlink for certain platforms (such as pc98). The
support for creating these symlinks was added to sys/conf/kern.post.mk in

from config(8), but config(8) was never updated.

The code is inspired by NetBSD sh somewhat, but different because we
preserve the old Almquist/Bourne/Korn ability to have an unquoted part in a
quoted ${v+word}. For example, "${v-"*"}" expands to $v as a single field if
v is set, but generates filenames otherwise.
Note that this is the only place where we split text literally from the
script (the similar ${v=word} assigns to v and then expands $v). The parser
must now add additional markers to allow the expansion code to know whether
arbitrary characters in substitutions are quoted.
Example:
for i in ${$+a b c}; do echo $i; done
