but serves to work around some uncleanliness whereby the ISA bus is not
found on Alpha systems with PCI:EISA bridges due to the lack of EISA code
for the Alpha.
no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.
be safely held across an eventhandler function call.
- Fix an instance of the head of an eventhandler list being read without
the lock being held.
- Break down and use a SYSINIT at the new SI_SUB_EVENTHANDLER to initialize
the eventhandler global mutex and the eventhandler list of lists rather
than using a non-MP safe initialization during the first call to
eventhandler_register().
- Add in a KASSERT() to eventhandler_register() to ensure that we don't try
to register an eventhandler before things have been initialized.
the witness code is compiled in. Without this, the witness code doesn't
notice that sched_lock is released by fork_trampoline() and thus gets all
confused about spin lock order later on.
macros, the mutex KTR log entries don't actually have the useful filename
and line numbers in the KTR_EXTEND case, so remove a comment claiming this
and go back to one set of KTR strings.
the ISA bus.
- Don't expect that a PCI:ISA bridge will have a correct class value;
if we're checking PCI IDs, only depend on these.
This should fix the loss of ISA on machines with PCI:EISA bridges like the
AS4100.

previously, only ev4 AS1000s and ev5 AS1000a's would have worked.

held and panic if so (conditional on witness).
- Change witness_list to return the number of locks held so this is easier.
- Add kern/syscalls.c to the kernel build if witness is defined so that the
panic message can contain the name of the offending system call.
- Add assertions that Giant and sched_lock are not held when returning from
a system call, which were missing for alpha and ia64.
can lead to further panics.
- Call getnanotime() instead of nanotime() for the timestamp. nanotime()
is more precise, but it also calls into the timer code, which results
in mutex operations on the i386 arch. If KTR_LOCK is turned on, then
ktr_tracepoint() recurses on itself until it exhausts the kernel stack.
Eventually this should change to use get_cyclecount() instead, but that
can't happen if get_cyclecount() is calling nanotime() instead of
getnanotime().
for a hung `daily' run to keep a `weekly' run from happening.
Same for `monthly'. We have always run `weekly' and `monthly' reguardless
of the execution status of `daily'. Until there is some consensus we should
not change the behavior.

carry this list of device IDs around.
cases with file fragments and read-write mmap's can lead to a situation
where a VM page has odd dirty bits, e.g. 0xFC - due to being dirtied by
an mmap and only the fragment (representing a non-page-aligned end of
file) synced via a filesystem buffer. A correct solution that
guarentees consistent m->dirty for the file EOF case is being
worked on. In the mean time we can't be so conservative in the
KASSERT.
