For -l, upset everyone by breaking it. Specifically, -l now produces
a lengthy error message that suggests --check-links (POSIX -l) or
--one-file-system (GNU -l) instead. However, if POSIXLY_CORRECT is set,
use the POSIX interpretation.
For -o, please everyone by making it work both ways:
* -xo uses POSIX behavior
* -co uses "almost GNU" behavior (as close as we can get until
libarchive implements a true V7 tar format)
Cleanup to prepare for locking commit. Add comments, clarify printfs,
remove old unused locking macros. Additional changes:
* Remove an old workaround for the bug in AcpiEnterSleepState() that
caused it to return with the hardware mutex still held. It no longer
can fail this way.
* Remove ACPI_DEBUGGER checkpoints in the probe. We have a reasonably
stable probe/attach process now.
* Use an sbuf instead of sprintf/strcat for a sysctl. Also, use strlcpy
instead of a bzero/strncpy.
* Simplify acpi_name, acpi_Enable, and acpi_Disable.
* Don't bzero the softc
and setting MSR. This was most evident with the idle proc running
with interrupts disabled and causing a lockup. Switch over to the
i386 style which does things in the right order.

pipelock(), not via a mixture of mutexes and pipelock(). Additionally,
add a few KASSERTS, and change some statements that should have been
KASSERTS into KASSERTS.
As a result of these cleanups, some segments of code have become
significantly shorter and/or easier to read.
unconditionally, stop after the first one (system board) if no EISA hardware
is detected. This fixes a boot hang (i.e. Thinkpad) when ACPI is disabled.
Also, split the probe code into a separate function and do some style cleanup.
Note that the Adaptec 2842 VLB controller probe is broken by this change
and will fail to probe. It should be fixed separately.

that actually need it. This makes it easier for a platform porter to
find the files that may need tweaking to support whatever MD specific
partitioning is needed. It also helps to prevent that the libdisk API
gets exposed and/or used where it's not needed.
While here:
o Make the UUIDs static to avoid runtime initialization,
o Rename ext to mslinux,
o Replace the use of memcmp() with uuid_equal(),
o Various style(9) improvements,
o Order the comparisons based on importance,
o Remove the word partition from all the descriptions,
o Other description improvements.

some debug support turned on. It turns out the sections in this driver
binary had relative virtual addresses (RVAs) that were different
from the raw addresses, and it had a .data section where the virtual size
was much larger than the raw size. (Most production binaries produced
with the Microsoft DDK have RVA == PA.)
There's code in the ndiscvt(8) utility that's supposed to handle
the vsize != rsize case, but it turns out it was slightly broken,
and it failed to handle the RVA != RA case at all. Hopefully, this
commit will fix all that.
UFS2 was here. It so happened that UFS2 did not need a seperate
partition type. Keep the definition as a comment for documentation
purposes. If there is a benefit for UFS2 file systems to have a
seperate partition type under GPT, then this definition should be
restored as that was the intention of the definition.
Currently one cannot load the mem.ko module without panicing if mem is
compiled into the kernel and one cannot build a kernel w/o "device mem"
right now either. Thus it is too dangerous to install mem.ko right now
because if one puts 'mem_load="YES"' in /etc/loader.conf they cannot
boot an "old" kernel (at the time that a kernel doesn't have to be built
with "device mem).
pic_eoi_source() into one call. This halves the number of spinlock operations
and indirect function calls in the normal case of handling a normal (ithread)
interrupt. Optimize the atpic and ioapic drivers to use inlines where
appropriate in supporting the intr_execute_handlers() change.
This knocks 900ns, or roughly 1350 cycles, off of the time spent servicing an
interrupt in the common case on my 1.5GHz P4 uniprocessor system. SMP systems
likely won't see as much of a gain due to the ioapic being more efficient than
the atpic. I'll investigate porting this to amd64 soon.

avoids some cases of extremely inefficient memory use that can occur
when large (e.g. 64k) blocks on the free list get used when allocating
a 4k chunk of 64-byte fragments. Because fragments have their own
free list, the 60k difference got lost forever every time.
