be used to index tables of counters.
Remove intr_dispatch() inline, it is implemented directly in tl*_intr now.
Count stray interrupts in a table of counters like intrcnt.
Disable interrupts briefly when setting up the interrupt vector table.
We must disable interrupts completely, not just raise the pil.
Pass pointers to the intr_vector structures rather than a vector number
to sched_ithd and intr_stray.
to kern_synch.c in preparation for adding some jitter to the
inter-sample time.
Note that the "vm.loadavg" sysctl still lives in vm_meter.c which
isn't the right place, but it is appropriate for the current (bad)
name of that sysctl.

off to witness_init() making the check for double intializating a lock by
testing the LO_INITIALIZED flag moot. Workaround this by checking the
LO_INITIALIZED flag ourself before we bzero the lock structure.
Add some missing break statements in the socket ioctl switch.
Check the return value from copyin() / copyout().
Fix some disorderings and misindentations.
Support a couple more socket ioctls.
Add missing break statements.
be so dangerous it isn't funny. eg: if you panic inside NFS or softdep,
and then try and sync you run into held locks and cause either deadlocks,
recursive panics or other interesting chaos. Default is unchanged.
- Change LOCK_DEBUG so that it is always on if KTR is compiled in
regardless of the state of KTR_COMPILE. This means that we no longer
need to include sys/ktr.h before sys/lock.h to ensure a valid setting
for LOCK_DEBUG.
- Change the use of LOCK_DEBUG so that it is now always defined and its
value is used instead of merely its definition. That is, instead of
#ifdef LOCK_DEBUG, code should now use #if LOCK_DEBUG > 0.
- Use this latest to #error out in sys/mutex.h if sys/lock.h isn't
included before sys/mutex.h to ensure that the proper versions of the
mutex operations are used.
- As a result of (2) sys/mutex.h no longer includes sys/ktr.h in the
KERNEL case.

This solves the problems with having to deal with howmany and which
devices are open.
For hysterical reasons ONLY, make a link to both the acdNa & acdNc devices.
structure. This makes it possible to pre-allocate PTEs for the kernel,
which is necessary for a reliable implementation of pmap_kenter(). This
also avoids wasting space (about 48 bytes per page) for kernel mappings
and user mappings of memory-mapped devices.
This also fixes a bug with the previous version where the implementation
required the pv_entry structure to be physically contiguous but did not
enforce this (the structure size was not a power of two). This meant
that the pv_entry free list was quickly corrupted as soon as the system
was even mildly loaded.
that appeared to be very different from the MI version. These
differences were mostly bogus and caused by copying octal
definitions and write them as hexadecimal values without doing
any base conversion (ie 010 was copied to 0x10). After filtering
out these differences, any remaining (real) incompatibilities
have been merged into the MI header file to make them more visible.
While here, fix the termios <-> termio conversion WRT to the c_cc
field for Alpha. The termios values do not match the termio values
and thus prevents us from copying.
By eliminating the Alpha MD copy of linux_ioctl.h we also fixed
the recent build breakage caused by putting new bits in the MI
header and not in the MD header.
