part of the structure was a hack to maintain binary compatibility with
Sun binaries, and my understanding is that it's not needed generally
on sparc systems running other operating systems. Therefore, hide this
code behind the same set of tests as in lib/bind/include/netdb.h.
This file is being imported on the vendor branch because a similar change
(or change with similar effect) will be in the next version of BIND 9.
This change will not affect other platforms in any way.
- Remove a conditional in the AMD cache detection, it's always false. [2]
- Don't try to detect a cache if only compiled for i386.

that a file's atime and mtime are only set to correct fractional
second values (0-999999000ns with the current interface).
Prior to this change users could create files with values outside
that range. Moreover, on 32-bit machines tv_usec offsets larger than
4.3s would result in an unnormalized AND wrong timestamp value,
due to overflow.

success instead of EOPNOTSUPP when being loaded. Secondly, if there are no
ibcs2 processes running when a MOD_UNLOAD request is made, break out to
return success instead of falling through into the default case which
returns EOPNOTSUPP. With these fixes, I can now kldload and subsequently
kldunload the ibcs2 module.

- Change the 'ident' paramters to 'wchan' to match <sys/systm.h>.
- Use 'otherwise' in place of 'else' in one place so that this reads like
English rather than C.
- Document the new msleep_spin() function.
- Add history notes for msleep() and msleep_spin().
functions in the child after a fork() from a threaded process,
use __sys_setprocmask() rather than setprocmask() to keep our
signal handling sane. Without this fix, signals are essentially
ignored in said child and things such as protection violations
result in an endless busy loop.

where su is executing (t)csh. csh's job handling is a little more
special than that of (a)sh, bash and even zsh and blows up a little
more spectacularly. This modification restores the original mucking
about with the tty pgrp, but is careful to only do it when su (or
su's child) is the foreground process.

requiried to keep consistent softc state before/after callback function
invocation and supposed to be sligntly faster than previous one as it
wouldn't incur callback overhead. With this change callback function

- Decrease TI_MAXTXSEGS to 32 from 128. It seems that most mbuf chain
length is less than 32 and it would be re-packed with m_defrag(9) if
its chain length is larger than TI_MAXTXSEGS. This would protect ti(4)
against possible kernel stack overflow when txsegs[] is put on stack.
Alternatively, we can embed the txsegs[] into softc. However, that
would waste memory and make Tx/Rx speration hard when we want to
sperate Tx/Rx handlers to optimize locking.
- Fix dma map tracking used in Tx path. Previously it used the dma map
of the last mbuf chain in ti_txeof() which was incorrect as ti(4)
used dma map of the first mbuf chain when it loads a mbuf chain with
bus_dmamap_load_mbuf(9). Correct the bug by introducing queues that
keep track of active/inactive dma maps/mbuf chain.
- Use ti_txcnt to check whether driver need to set watchdog timer instead
of blidnly clearing the timer in ti_txeof().
- Remove the 3rd arg. of ti_encap(). Since ti(4) now caches the last
descriptor index(ti_tx_saved_prodidx) used in Tx there is no need to
pass it as a fuction arg.
- Change data type of producer/consumer index to int from u_int16_t in
order to remove implicit type conversions in Tx/Rx handlers.
- Check interface queue before getting a mbuf chain to reduce locking
overhead.
- Check number of available Tx descriptores to be 16 or higher in
ti_start(). This wouldn't protect Tx descriptor shortage but it would
reduce number of bus_dmamap_unload(9) calls in ti_encap() when we are
about to running out of Tx descriptors.
- Command NIC to send packets ony when the driver really has packets
enqueued. Previously it always set TI_MB_SENDPROD_IDX which would
command NIC to DMA Tx descriptors into NIC local memory regardless
of Tx descriptor changes.
