I am not sure if this is absolutely necessary on all systems. Yet,
there certainly are motherboards and notebook systems which require
this, although there are other systems which just don't. I hope we
shall know when to do this on which systems, as the development of our
ACPI subsystem progresses... (I know we didn't need this for the APM
resume.)
all the debugging code into the function versions of the mutex operations
in kern_mutex.c. This reduced the __mtx_* macros to simply wrappers of
the _{get,rel}_lock_* macros, so the __mtx_* macros were also abolished in
favor of just calling the _{get,rel}_lock_* macros. The tangled hairy mass
of macros calling macros is at least a bit more sane now.
* Don't get confused when memory regions don't lie on page boundaries -
remember our page size is typically larger than the firmware's page size.
* Add a function ia64_running_in_simulator() which is intended to detect
whether the kernel is running in SKI or on real hardware.

was locked by the proc lock and td_flags is locked by the sched_lock.
The places that read, set, and cleared TDF_SELECT weren't updated, so they
read and modified td_flags w/o holding the sched_lock, meaning that they
could corrupt the per-thread flags field. As an immediate band-aid,
grab sched_lock while reading and manipulating td_flags in relation to
TDF_SELECT. This will probably be cleaned up some later on.
credentials rather than the real credentials. This is useful for
implementing GUI's which need to modify icons based on access rights,
but where use of open(2) is too expensive, use of stat(2) doesn't
reflect the file system's real protection model, and use of
access() suffers from real/effective credential confusion. This
implementation provides the same semantics as the call of the same
name on SCO OpenServer. Note: using this call improperly can
leave you subject to some of the same races present in the
access(2) call.
o To implement this, break out the basic logic of access(2) into
vpaccess(), which accepts a passed credential to perform the
invocation of VOP_ACCESS(). Add eaccess(2) to invoke vpaccess(),
and modify access(2) to use vpaccess().

- SC_CUT_SPACES2TABS - when copying text into the cut buffer convert leading
spaces into the tabs;
- SC_CUT_SEPCHARS="XYZ" - treat supplied characters as possible words
separators when the driver searches for words boundaries when doing cut
operation.
Also unify cut code a bit to decrease amount of duplicated code. This fixes
line cut mode, so that it is no longer pads line with useless spaces.

as a physical atomic operation. That would require the code to use the
atomic API, which it does not. Instead, the operation is made psuedo
atomic (hence the quotes) by use of the lock to protect clearing all of the
flags in question.
NAT in extended passive mode if the server's public IP address was
different from the main NAT address. This caused a wrong aliasing
link to be created that did not route the incoming packets back to
the original IP address of the server.
natd -v -n pub0 -redirect_address localFTP publicFTP
Note that even if localFTP == publicFTP, one still needs to supply
the -redirect_address directive. It is needed as a helper because
extended passive mode's 229 reply does not contain the IP address.

BUGFIX: fix a problem in old code which prevented reallocation of
the hash table for dynamic rules (there is a PR on this).
OTHER CHANGES: minor changes to the internal struct for static and dynamic rules.
Requires rebuild of ipfw binary.
Add comments to show how data structures are linked together.
(It probably makes no sense to keep the chain pointers separate
from actual rule descriptors. They will be hopefully merged soon.

can set timeouts for closing connections to much shorter times.
merge zero_entry() and resetlog_entry(), they use basically the
same code.
clean up and reduce replication of code for removing rules,
both for readability and code size.
introduce a separate lifetime for dynamic UDP rules.
fix a problem in old code which prevented reallocation of

restructure dynamic rule descriptors
introduce some local variables to avoid multiple dereferencing of
pointer chains (reduces code size and hopefully increases speed).
seems to set up memory spaces correctly. This change actually did work for
me using -STABLE, XFree86 4.0.3 ~ some snapshot of DRI awhile back. I sent
mail to dfr to no avail, perhaps someone else would like to test it with
DRI.
Anyway, people have been nagging me about this change for awhile, so here's
the commit.

Also increase the size of the RX ring to 128 descriptors (was 64).

abstract the securelevel implementation details from the checking

generally speaking, there are few instances of this, and they should
be fixed.

Please note, that due to limit on the amount of memory available to the
loader(8), it is possible to load modules/kernels compressed with the smallest
block size supported by the bzip2 - 100k (`-1' bzip2(1) option), however
even in this mode bzip2(1) usually provides better compression ratio than
gzip(1) in its best compression mode.
