the NFS subsystems use five of the rpcsec_gss/kgssapi entry points,
but since it was not obvious which others might be useful, all
nineteen were included. Basically the nineteen entry points are
set in a structure called rpc_gss_entries and inline functions
defined in sys/rpc/rpcsec_gss.h check for the entry points being
non-NULL and then call them. A default value is returned otherwise.

(Saying that the lock on the object that the page belongs to must be held
only represents one aspect of the rules.)
Eliminate the use of the page queues lock for atomically performing read-
modify-write operations on the dirty field when the underlying architecture
supports atomic operations on char and short types.
Document the fact that 32KB pages aren't really supported.

to be created. The support is based on mtree version 2.0, as used
in libarchive, but adds new features on top of it.
The current implementation is fully functional, but is envisioned
to grow at least the following additional features over time:
o Add support for the /include special command so that manifest
files can be constructed using includable fragments.
o Add support specifying a search path to locate content files.
o Content file filters: commands that provide file contents on
stdout.
The manifest file eliminates the need to first construct a tree
as root in order to create an image and allows images (releases)
to be created directly from object trees and/or source trees.

Some of loader filesystems are very ill equipped to handle seeking

restarted from the start of the file every time we go backwards.

This is just a bandaid until somebody can fix this correctly. The code
is just a broken as it was before r223262 - now buildworld just doesn't

POSIX requires a -h option to sh and set, to locate and remember utilities
invoked by functions as they are defined. Given that this
locate-and-remember process is optional elsewhere, it seems safe enough to
make this option do nothing.
POSIX does not specify a long name for this option. Follow ksh in calling it
"trackall".
cloned from the old NFS client, plus additions for NFSv4. A
review of this code is in progress, however it was felt by the
reviewer that it could go in now, before code slush. Any changes
required by the review can be committed as bug fixes later.
If a file is mapped with with MAP_PRIVATE, no write permission is required
and changes do not end up in the file. Therefore, tools like fuser and fstat
should not show the file as open for writing.
The protection as displayed by procstat -v still includes write in this
case, and shows 'C' for copy-on-write.
The code did !strncasecmp(str, "sig", 4) which is not useful.
Also change "sig" to "SIG" matching the uppercase signal names as of
r218285. This has little effect because fuser does not enable locale.
interrupts. Bringup on additional machine models repeatedly reveals
firmware that enables interrupts behind our back, causing the console
to be flooded otherwise.
- As with the regular interrupt counters using uint16_t instead of
u_long for counting the stray vector interrupts should be more than
sufficient.
- Cache the interrupt vector in intr_stray_vector().
o Set TP using inline assembly to avoid dead code elimination.
o Eliminate _tcb.

Stylize: avoid using a global register variable.
Merge from r157461:
Simplify _get_curthread() and _tcb_ctor because libc and rtld now
already allocate thread pointer space in tls block for initial thread.
Merge from r177853:
Replace function _umtx_op with _umtx_op_err, the later function directly
returns errno, because errno can be mucked by user's signal handler and
most of pthread api heavily depends on errno to be correct, this change
should improve stability of the thread library.

With the current sh, placing eval in a command substitution always results
in a fork(), even if it is the only command and only executes a single
simple command. Therefore, avoid it where it can be avoided easily.
Side effect: values starting with a hyphen and all whitespace are preserved.
The values are defaults and names for rc.conf variables and messages to be
given about obsolete ones.

On MP systems this is not a usable solution anymore and could easily
lead to false positives triggering enough logging that even using
the console was no longer usable (multiple parallel ping -f can do).
Switch to the suggested solution of using mbuf tags to carry per
packet state between gre_output() invocations. Contrary to the
proposed solution modelled after gif(4) only allocate one mbuf tag
per packet rather than per packet and per gre_output() pass through.
As the sysctl to control the possible valid (gre in gre) nestings does
no sanity checks, make sure to always allocate space in the mbuf tag
for at least one, and at most 255 possible gre interfaces to detect
loops in addition to the counter.

On boot, some laptops with certain cards in them sometimes fail on
boot, but if the card is inserted after boot it works. Experiments
show that small delays here makes things more reliable. It is
believed that some combinations need a little more time before the
power on the card is really stable enough to be reliable once the
power is stable in the bridge.
some times compiler inserts redundant instructions to preserve unused upper

the problem becomes more serious when it is shifted, especially on amd64.
