Only if __HAVE_GENERIC_SOFT_INTERRUPTS is then splusb == splsoftnet
(because we register the interrupt with IPL_SOFTNET). However, if
we're using a callout, then splusb == splsoftclock (because the
callouts happen from the softclock interrupt).
Note that splsoftnet blocks softclock interrupts, but this is
meant to better describe what's going on.
constructs an ELF image, consisting of the ELF header, for
each memory region a program header, followed by the memory
contents for each region. It does blocked I/O for the headers
as they are typically smaller than DEV_BSIZE.

Change the operation of the USB event thread. Before it only
performed USB device discovery, now it can also perform (short)
tasks for device drivers that need a process context, but don't
have one. This is not pretty, but better than using busy-wait
in an interrupt context.
Rename memlock to sysctllock, and MEMLOCK()/MEMUNLOCK() to SYSCTL_LOCK()/
SYSCTL_UNLOCK() and related changes to make the lock names make more
sense.

following sysctl variables:
debug.mutex.prof.enable enable / disable profiling
debug.mutex.prof.acquisitions number of mutex acquisitions recorded
debug.mutex.prof.records number of acquisition points recorded
debug.mutex.prof.maxrecords max number of acquisition points
debug.mutex.prof.rejected number of rejections (due to full table)
debug.mutex.prof.hashsize hash size
debug.mutex.prof.collisions number of hash collisions
debug.mutex.prof.stats profiling statistics
The code records four numbers for each acquisition point (identified by
source file name and line number): longest time held, total time held,
number of non-recursive acquisitions, average time held. The measurements
are in clock cycles (as returned by get_cyclecount(9)); this may cause
measurements on some SMP systems to be unreliable. This can probably be
worked around by replacing get_cyclecount(9) by some incarnation of
nanotime(9).
This work was derived from initial patches by eivind.
and cpu_critical_exit() and moves associated critical prototypes into their
own header file, <arch>/<arch>/critical.h, which is only included by the
three MI source files that need it.
Backout and re-apply improperly comitted syntactical cleanups made to files
that were still under active development. Backout improperly comitted program
structure changes that moved localized declarations to the top of two
procedures. Partially re-apply one of the program structure changes to
move 'mask' into an intermediate block rather then in three separate
sub-blocks to make the code more readable. Re-integrate bug fixes that Jake
made to the sparc64 code.
Note: In general, developers should not gratuitously move declarations out
of sub-blocks. They are where they are for reasons of structure, grouping,
readability, compiler-localizability, and to avoid developer-introduced bugs
similar to several found in recent years in the VFS and VM code.

code can use it. This takes a single constant argument and fails to compile
if it is 0 (false). The main application of this is to make assertions about
structure sizes at compile time, in order to validate assumptions made in
other code. Examples:
CTASSERT(sizeof(struct foo) == FOO_SIZEOF);
CTASSERT(sizeof(struct foo) == (1 << FOO_SHIFT));

Add code to use soft interrupt to handle USB interrupt processing.
Don't enable the code since it doesn't work with the kludgy Ethernet
drivers.
general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

In uhci_intr(), only warn about power state confusion if the
interrupt was actually for us.
