- Remove the ifdef'ed out SBus interrupt priority code and the hook for
ncr53c9x_reset(), remove the unused SBus interrupt priority member from
esp_softc. On FreeBSD setting the SBus interrupt priority is entirely done
in sbus(4) and the reset function isn't even really used in NetBSD.

- Remove dv_name from the lsi64854_softc and use device_printf() instead.
- Use __func__ instead of hardcoded function names in error messages.
- Use ulmin() instead of min() for comparing the DMA sizes as the values
involved actually are represented by 64bit unsigned instead of 32bit
unsigned. As far as I can't tell this doesn't make a difference in
practice though.

- Remove unnecessary braces.

to see if additional write requests will arrive that can be coalesced and
clustered with earlier ones. When doing so, it must determine whether
the two requests are made by credentials with the same access writes, so
as not to coalesce improperly. NFSW_SAMECRED() implements a test of two
credentials using a binary compare.
Replace NFSW_SAMECRED() macro with nfsrv_samecred() function, which is
aware of the contents and layout of a struct ucred, rather than a simple
binary compare. While the binary compare works when ucred is simply a
zero'd and embedded 'struct ucred' in the NFS descriptor, it will work
less well when the ucred associated with an NFS descriptor is "real", so
has defined and populated reference count, mutex, etc.

- In the bus probe nomatch function print the resources of the children

- For the clock frequency IVAR use the per-child values and fall back to
the bus default in case a child doesn't have the respective property
instead of always using the bus default so a child driver doesn't need
to obtain the per-child value itself (see also the commit message of

sbus_alloc_resource() wasn't quite correct, we need to support pass-

Since the name cache is case-sensitive and msdosfs isn't,
creating a file 'foo' won't invalidate a negative entry for 'FOO'.
There are similar problems related to 8.3 filenames.
A better solution is to override VOP_LOOKUP with a method that
canonicalizes the name, then calls vfs_cache_lookup(). Unfortunately,
it's not quite that simple because vfs_cache_lookup() will call
msdosfs_lookup() on a cache miss, and msdosfs_lookup() needs a way to
get at the original component name.

Don't use atomic ops to increment interrupt stats.
On sparc64 this reduces delay until tick interrupts are service by 1/10th
on average. In turn this reduces the clock drift caused by these delays
so there's less drift which has to be compensated in tick_hardclock().
This includes switching from atomically incrementing the global cnt.v_intr
to the asm equivalent of PCPU_LAZY_INC(cnt.v_intr) in exception.S
- Correct some comments to match the registers actually used.
- Correct some format specifiers, interrupt levels passed in are u_int.

- Fix NULL pointer dereferences caused when an ithread or a handler is
NULL which happens when a stray interrupt triggers after the respective
device interrupt was torn down.
- Remove the critical section around INTR_FAST handlers which actually
was a nested critical section. Both tl0_intr() and tl1_intr() already
enter a critical section for calling intr_execute_handlers().

- In tick_start() don't reset the tick counter of the boot processor to
zero. It's initially reset in _start() and afterwards but _before_
tick_start() is called on the BSP the APs synchronise with the tick
counter of the BSP in mp_startup(). Resetting the tick counter of the
BSP in tick_start() probably also was the cause of problems seen when
using the CPU tick counter as timecounter on SMP machines.
Not resetting the tick counter of the BSP in mp_startup() makes the
tick counters and tick interrupts between the BSP and APs be pretty
much in sync as it's supposed to be. This also means there's no longer
a real reason to have separate tick_start() and tick_start_ap() so
merge them and zap tick_start_ap(). This is also a first step in
simplifying the interface to the tick counters in preparation to use
alternate clock hardware where available.
- Switch to the algorithm used on FreeBSD/ia64 for updating the tick
interrupt register and which compensates the clock drift caused by
varying delays between when the tick interrupts actually trigger and
when they are serviced. Not compensating the clock drift mainly hurts
interactive performance especially when using WITNESS. [2]
For further information about the algorithm also see the commit log
of sys/ia64/ia64/interrupt.c rev. 1.38.
On sparc64 the sysctls for monitoring the behaviour of the tick
interrupts are machdep.tick.adjust_edges, machdep.tick.adjust_excess,
machdep.tick.adjust_missed and machdep.tick.adjust_ticks.
- In tick_init() just use tick_stop() for stopping the tick interrupts
until a proper handler is set up later. This also stops the system
tick interrupt on USIII systems earlier.
- In tick_start() check for a rough upper limit of HZ.
- Some minor changes, e.g. use FBSDID, remove unused headers, etc.
