9f152ec7d2 aic7xxx.c:
Correct an off by one in our critical section handling.
		SEQADDR always reads the next instruction to execute,
		so we must subtract one from its value before making
		comparisons with entries in the critical section table.

		Print a few additional registers whenever we dump
		card state.

		Show the SCB_CONTROL and SCB_TAG values for all pending
		SCBs in card SCB ram when dumping card state.

	aic7xxx.seq:
		Fix a bug introduced while optimizing the SDPTR path.
		We would ack the SDPTR message twice on Ultra2 or better
		chips if it occurred after all data had been transferred
		for a transaction.

		Change our workaround for the PCI2.1 retry bug on some
		chips.  Although the previous workaround was logically
		correct, its faster method of draining the FIFO seemed
		to occassionally confuse the FIFO state.  We now drain
		the FIFO at half the speed which avoids the problem.

	aic7xxx_pci.c:
		Chips with the PCI 2.1 retry bug can't handle a 16byte
		cachesize.  If the cachesize is set to 16bytes, drop
		it to 0.

eade81c941 o Move APNIC flag from -p to -A. Since, -p is usually associated
with specifying a port.
o Add the -p flag for specifying a port.  (PR: 28790)  This is
  useful for querying rwhois servers.  Example:
    whois -h rwhois.exodus.net -p rwhois 216.136.180.0
o Add the -c flag which allows one to get the same whois server
  that would normally be determined if no arguments were specified.
  (Concept based on work by phantom, requested by ache)  Example:
    whois -c ru TCNET-MNT-RIPN
o Deprecate -R flag in favour of -c ru.

6369218752 Fix a number of bugs and annoyances in fdisk, many of which were
pointed out by bde:
- Ask for user confirmation before adjusting to a head/cylinder
  boundary (only when running interactively), and separate this
  adjustment from the automatic calculation of c/h/s parameters.
- In sanitize_partition, don't change any values in the slice until
  we know that the automatic adjustment will succeed.
- When auto-adjusting, ignore unused slices and give an appropriate
  error for other zero-size slices depending on the cause.
- Change dos() to do all of the c/h/s calculations for a whole slice;
  this fixes a bug where the ending c/h/s of an unused slice was set
  incorrectly.
- When changing the active slice, detect the currently active slice
  number instead of always defaulting to slice 4.
- Call fflush(stdout) before calling fgets().
- Test for fgets() returning NULL so we don't loop on EOF.

3d04a9d7e3 Once again throw out the calculation of si_iosize_max and set it to 64K.
Although it can go higher, it is not safe to so do on arrays with many
members.  Compromise by adding a tunable, "hw.aac.iosize_max" that can be
set at boottime.  Also document in the aac(4) manpage.

0d3576d9bc Now that we are setting a bit in the PCIC_INT_GEN (0x3) register, we
can't blindly write zero into it to disable the card.  We must
preserve this bit.  This changes pcic_disable to only clear the bits
we know we need to clear on card disable, thus preserving the magic
bit for many TI bridges.

This appears to have fixed the problems that people are reporting
about the system failing to recognize cards being inserted or removed
(or both).  Greg: This may fix your problem too :-).

f6c4dd3f48 Bugfixes. Close a race and logic bug in the timeout handling, don't call the
interrupt handler from the upper half, etc.  This fixes some serious stability
problems that we were seeing on our production server.  These patches have
been tested for almost 6 months and are a highly recommended MFC candidate.

c4a5ef6ef3 Add some features to libdevstat, and overhaul the interface a bit:
1.) prefix all functions in the library with devstat_ (compatability
    functions are available for all functions that were chaned in an
    incompatible way, but are deprecated).
2.) Add a pointer to a kvm_t as the first argument to functions that
    used to get their information via sysctl; they behave the same
    as before when NULL is passed as this argument, otherwise, the
    information is obtained via libkvm using the supplied handle.
3.) Add a new function, devstat_compute_statistics(), that is intended
    to replace the old compute_stats() function. It offers more
    statistics data, and has a more flexible interface.

libdevstat does now require libkvm; a library depedency is added, so
that libkvm only needs to be explicitely specified for statically linked
programs.
The library major version number is bumped.
