86d99b6884 Remove EISA bus support for add-in cards. Remove related kernel and
compile options. Remove doxygen pointers to now deleted files. Remove
EISA and VME as examples in bus_space.9.

Retained EISA mode code for IO PIC and MPTABLES because that's not
EISA bus, per se, and some people have abused EISA to mean "EISA-like
behavior as opposed to ISA" rather than using it for EISA add-in
cards.

a4e4cebf17 Remove EISA support from ahc driver. The AIC-7770 chip can be on ISA,
VesaLocalBus or EISA. Internally, EISA and ISA are handled the same,
with VL being handled slightly differently. To avoid too much code
churn, retain the EISA name, despite it being used only for ISA
bus. When it is on the ISA bus, weird gymnastics are required with
EISA-space address accesses as well. Remove known models from the ahc
man page. Remove ahc_eisa module.

643faabe0d pf: use inet_ntoa_r() instead of inet_ntoa(); maybe fix IPv6 OS fingerprinting
inet_ntoa() cannot be used safely in a multithreaded environment
because it uses a static local buffer. Instead, use inet_ntoa_r()
with a buffer on the caller's stack.

This code had an INET6 conditional before this commit, but opt_inet6.h
was not included, so INET6 was never defined.  Apparently, pf's OS
fingerprinting hasn't worked with IPv6 for quite some time.
This commit might fix it, but I didn't test that.

3600f4ba35 Fix a typo in my previous commit
Somehow in the late stages of testing my sched_ule patch, a character was
accidentally deleted from the file.  Correct this.

While I'm committing anyway, the previous commit message requires some
clarification: in the normal case of unlending priority after releasing
a mutex, the thread that was doing the lending will be woken up and
immediately become the highest-priority thread, and in that case no
priority inversion would take place.  However, if that thread is pinned
to a different CPU, then the currently running thread that just had its
priority lowered will not be preempted and then priority inversion can
occur.

09ae7c4814 Check for preemption after lowering a thread's priority
When a high-priority thread is waiting for a mutex held by a
low-priority thread, it temporarily lends its priority to the
low-priority thread to prevent priority inversion.  When the mutex
is released, the lent priority is revoked and the low-priority
thread goes back to its original priority.

When the priority of that thread is lowered (through a call to
sched_priority()), the schedule was not checking whether
there is now a high-priority thread in the run queue.  This can
cause threads with real-time priority to be starved in the run
queue while the low-priority thread finishes its quantum.

Fix this by explicitly checking whether preemption is necessary
when a thread's priority is lowered.

While a new bit was added and thread alignment got shifted to accomodate it,
RW_READERS_SHIFT was not modified accordingly and clashed with the new flag.

This was surprisingly harmless. If the lock was taken for writing, other flags
were tested. If the lock was taken for reading, it would correctly work for
readers > 1 and this was the only relevant test performed.
