AMD's ELAN documentation says that you write to the SYS_RST register
in the Memory Mapped Configuration Region (MMCR) to reset the CPU.
If CPU_ELAN is set, try this first to reset the CPU before the
traditional way.

On 4.X it was possible for an application to initialise a local FILE
structure and call stdio functions. In 5.X this was broken when FILE
locking was introduced into libc.
This change makes most (relevant) stdio functions work again when the
_extra file in FILE isn't initialised (and can't be without a libc
function to do it since the __sFILEX structure is private to libc).

Link pf to the build and install:

the proxy user. Make sure to run mergemaster -p in oder to complete make

This also provides the passive OS fingerprints from OpenBSD (pf.os) and an

For those who want to go without pf; it provides a NO_PF knob to make.conf.
__FreeBSD_version will be bumped soon to reflect this and to be able to
change ports accordingly.

Shift file locking to source file instead of temp file. This fixes
data buffering issue that corrupts files if two pw(8)'s run at the
same time as well as changing pw(8) so it uses the same locking
mechanism as PAM, vipw(8), pwd_mkdb(8), etc.
Add a check for wtmp records which have invalid values for ut_time. Wtmp
records with time==0 get "the time of the last valid record", while records
where time goes backwards (compared to the previous record) are skipped.
Also prints a message saying how many records were changed or skipped due
to these checks. Check was inspired by a simpler check in OpenBSD's version.
This is all meant to sidestep problems that Tillman Hodgson noticed with 'ac'
when running sparc64 with 64-bit time_t's. The real problem is whatever is
creating wtmp records with ut_time==0, of course, but I have not yet figured
out what is doing that.

Move a vref call outside of proc locks and Giant. By virtue of the fact
that we (p1) are currently running, we hold a reference on p_textvp which

Retire pmap_pinit2(). Alpha was the last platform that used it. However,
ever since alpha/alpha/pmap.c revision 1.81 introduced the list allpmaps,
there has been no reason for having this function on Alpha. Briefly,
when pmap_growkernel() relied upon the list of all processes to find and
update the various pmaps to reflect a growth in the kernel's valid
address space, pmap_init2() served to avoid a race between pmap
initialization and pmap_growkernel(). Specifically, pmap_pinit2() was
responsible for initializing the kernel portions of the pmap and
pmap_pinit2() was called after the process structure contained a pointer
to the new pmap for use by pmap_growkernel(). Thus, an update to the
kernel's address space might be applied to the new pmap unnecessarily,
but an update would never be lost.
Use one bus_dma_tag_t for all pSRB instead of creating one for each.

Add preliminary support for PCMCIA devices in addition to PCI/cardbus.

The ndiscvt(8) utility should be able to parse device info for PCMCIA
devices now. The ndis_alloc_amem() has moved from kern_ndis.c to
if_ndis_pccard.c so that kern_ndis.c no longer depends on pccard.
NOTE: this stuff is not guaranteed to work 100% correctly yet. So
far I have been able to load/init my PCMCIA Cisco Aironet 340 card,

PCI/cardbus devices should still work as before.

Recognize hardlinks when reading cpio files.
This doesn't yet address the issue of selective restore
of hardlinked files. With cpio format, it's possible to correctly
restore any linked file; the API doesn't yet fully support this.
(There's no way for the library to inform a client whether or not
there's a file body associated with this entry. The assumption
right now is that "hardlink" entries have no file body.)
Tim Kientzle [Sat, 6 Mar 2004 05:44:13 +0000 (05:44 +0000)]
Minor API tweak: The format-specific write_header function now sets
the size in the archive_entry object to zero if that format doesn't
store a body for that file type. This allows the client to determine
whether or not it should feed the file body to the archive. In
particular, cpio stores the file body for hardlinks, tar and shar
don't. With this change, bsdtar now correctly archives hardlinks in all
supported formats.
While I'm here, make shar output be more aggressive about creating directories.
Before this, commands such as:
bsdtar -cv -F shar some/explicit/path/to/a/file
wouldn't create the directory. Some simple logic to remember the last
directory creation helps reduce unnecessary mkdirs here.
At this point, I think the only flaw in libarchive's cpio support is
the failure to recognize hardlinks when reading.
Always call vn_finished_write after vn_start_write was called. All
occurences of 'goto done' after vn_start_write invocation were cleaning
up incompletely.
