While I'm here make sure established link is IFM_10_T or
IFM_100_TX as bfe(4) just supports 10/100Mbps media.

This fixes potential out-of-bound accesses when testing ciphers with block size

During the import of the MPSAFE TTY layer (r181905), I changed
acct_process() to lock proctree_lock instead of SESS_LOCK, because
s_ttyp is now locked using proctree_lock. One of the things I forgot,
was to lock it before we PROC_LOCK.
Commit this patch, written by kib@. To ensure we hold proctree_lock as
short as possible, obtaining `ac_tty' has now been made the first step
of filling `acct'.

This is easy to confuse with the actual exit status of the program.
Instead exit with EX_SOFTWARE if the command doesn't exit normally.

I would like to provide a way to preview the effects of pathname edits,
but pattern selection has to happen against the unedited path, so it
seems that we have to show people the unedited path to help in
designing selection patterns.
o Removed unneeded header files.
o bus_dma(9) fix:
- created parent tag with 1GB dma address limit with no
alignment restrictions.
- set 4096 alignment limit for Tx/Rx descriptor rings.
- separate Rx buffer tag from Tx buffer tag such that Tx tag
allows up-to 16 segments while Rx buffer tag only allows
single segment.
- it seems the controller has no alignment restrictions on Tx/Rx
buffers. Remove ETHER_ALIGN alignment restriction in Tx/Rx
buffers.
- created a spare Rx dma map which would be used to cope with
failure of loading a dma map.
- make sure to load full Tx/Rx descriptor size for Tx/Rx
descriptor dma maps, previously bfe(4) used to load single
descriptor size for each descriptor rings. I have no idea how
it could be run without problems.
- don't blindly cast bus_addr_t type to 32bits in bfe_dma_map().
- created bfe_dma_free() to free allocated dma memory/tags.
- make sure to invoke bus_dmamap_sync(9) before/after processing
descriptor rings/buffers. Because the hardware has severe dma
address space limitation, bounce-buffers would be always used
on systems with more than 1GB memory during
descriptors/buffers access.
- added Tx descriptor ring initialization function,
bfe_list_tx_init().
- moved producer/consumer index initialization to
bfe_list_tx_init() and bfe_list_rx_init() from
bfe_chip_reset().
- added bfe_discard_buf() which will update loaded descriptors
without unloading/reloading the dma map to speed up error
recovery.
- implemented Tx side bus_dmamap_load_mbuf_sg(9). The number of
segments allowed was chosen to be 16 which should be enough for
non-TSO capable hardwares. Setting SOF bit of Tx descriptor is
done in the last to avoid potential race.
- don't give up sending frames in bfe_start() until the hardware
lacks free descriptors.
- added XXX comment to second kick command and possible workaround.
- implemented Rx side bus_dmamap_load_mbuf_sg(9).
- removed bfe_dma_map_desc() as it's not needed anymore after
the conversion to bus_dmamap_load_mbuf_sg(9).
- added endianness support. With this change bfe(4) should work
on any architectures that can create bounce buffers within 1GB
address range.
- add missing bus_dmamap_sync() in bfe_tx_eof()/bfe_rx_eof().
o Use PCI_BAR instead of hardcoded value to set BARs.
Simplified register access with bus_write_4(9)/bus_read_4(9) and
removed bfe_btag, bfe_bhandle, bfe_vhandle in softc as it's not
used anymore.
o Reorder device detach logic such that bfe_detach() is also used
for handling driver attach failure case.
o Remove unnecessary KASSERT in bfe_detach().
o Remove bfe_rx_cnt, bfe_up, bfe_vpd_prodname, bfe_vpd_readonly in
softc. It's not used at all.
o Remove BFE_RX_RING_SIZE/BFE_RX_RING_SIZE/BFE_LINK_DOWN.

These man pages refer to drivers that I'm aware that work on amd64. Most
likely there are more, but I'll deal with them later.

memory area's base and limit are optional. The low 4-bits of the "low"
prefetchable registers indicates whether or not a 32-bit or 64-bit
region is supported. The PCI-PCI driver had been assuming that all bridges
supported a 64-bit region (and thus the two upper 32-bit registers). Fix
the driver to only use those registers if the low 4-bits of the "low"
registers indicate that a 64-bit region is supported. The PCI-PCI bridge
in the XBox happens to be a bridge that only supports a 32-bit region.

complains about "Malformed numbers" while unpacking the dists and
what winds up on the disk isn't correct. Use this as an opportunity
to switch over to bsdcpio since at this point we don't even build
and install the gnu cpio by default. Note sysinstall needed to be
tweaked a bit (dropping tape block size setting) because it seems
bsdcpio doesn't do anything with block sizes, at least as far as
reading from archives goes. That wasn't really a problem since
installations from tape have been broken for a while and the rest
of sysinstall's tape support code will be removed shortly.
tape have been broken for quite a while, and I'll be removing the rest
of sysinstall's knowledge of tapes shortly. I'm doing this piece now
because I want to switch from gnu's cpio to bsdcpio being integrated

block sizes at all.

This may contain multibyte characters (e.g. when using UTF-8).
This string is then aligned on byte-length rathern than char-length,
resulting in misalignment and unfinished multibyte characters.

We used to have a single wait channel inside the kernel which could be
used by threads that just wanted to sleep for some time (the next
second). The old TTY layer was the only piece of code that still used
lbolt, because I already removed the use of lbolt from the NFS clients
and the VFS syncer.

The routines in grantpt.c have been moved to ptsname.c in the MPSAFE TTY
layer, because grantpt() is now effectively a no-op. I forgot to remove
the corresponding source file from libc.
I initially didn't want to integrate the Xen console driver, because it
did not receive any testing. Kip Macy suggested that I'd better check it
in right now, because this is the easiest way for him to test it while
he is working on the Xen import.

For some reason, sys/sys/tty.h was only half patched. This went by

The previous commit also included changes to all the system call lists,
but it is a tradition to update these lists in a second commit, so rerun
make sysent to update the $FreeBSD$ tags inside these files to refer to
