gadgets (hotkeys, lcd, ...) on Asus laptops. I aim to closely track the
acpi4asus project which implements these features in the Linux kernel.
If this breaks your laptop, please let me know how it does it :-)

like "the foo(4) manual page" to "foo(4)". Uniformized the remaining
instances of "manual page" and "manpage" to "man page". Uniformized
some nearby sentence breaks. Reformatted the whole paragraph containing
these changes only for DUMMYNET.
The VIA Nehemias is so obviously specific to i386 that it should not
be compiled on non-i386 platforms. The obviousness is in the fact that
all functions in nehemias.c are purely i386 inline assembly, guarded
by #ifdef __i386__
can more easily be used INSTEAD OF the hard-working Yarrow.
The only hardware source used at this point is the one inside
the VIA C3 Nehemiah (Stepping 3 and above) CPU. More sources will
be added in due course. Contributions welcome!
to awaken all waiters when a contested mutex is released instead of just
the highest priority waiter. If the various threads are awakened in
sequence then each thread may acquire and release the lock in question
without contention resulting in fewer expensive unlock and lock
operations. This old behavior of waking just the highest priority is
still used if this option is specified. Making the algorithm conditional
on a kernel option will allows us to benchmark both cases later and
determine which one should be used by default.

stuff was here (NFS) was fixed by Alfred in November. The only remaining
consumer of the stub functions was umapfs, which is horribly horribly
broken. It has missed out on about the last 5 years worth of maintenence
that was done on nullfs (from which umapfs is derived). It needs major
work to bring it up to date with the vnode locking protocol. umapfs really
needs to find a caretaker to bring it into the 21st century.
Functions GC'ed:
vop_noislocked, vop_nolock, vop_nounlock, vop_sharedlock.
was not present in what I originally tested when checking to see if
the kernel built/ran with the -O2 change. Recent instability in
sparc64 kernel was tracked to this. A reproducible kernel stack
traceback followed by hard hang during the call to msleep() at the
point the kernel waits 15 seconds for the SCSI bus to settle crept in
to recent kernel builds and it seems to go away with this patch.

extra entry for if_ndis_pci.c that depends on cardbus, just to cover
all the bases. (I don't think you can have cardbus without PCI, but
just in case...)
implementation could be characterized as a hybrid of the amd64 and i386
implementations. Specifically, the direct virtual-to-physical mapping is
used if possible and sf_buf_alloc() is used if the direct map cannot.
to select a serial console and debug port (resp). On ia64 these replace
the use of hints completely and take precedence over hints on alpha,
amd64 and i386. On sparc64 these variables are not yet recognised.
The reasons for introducing these variables are:
1. Hints have side-effects. They reserve the unit number for use by
isa or acpi devices and therefore cannot be used to select a pci
device. Also, the use of a unit number to select a device prior
to bus enumeration is nonsense. The new variables have no side-
effects and are not based on unit numbers.
2. Hints don't have the expression power to allow the sysadmin to
select UARTs that are not legacy PC devices and need the support
of compile-time constants to give the sysadmin some level of
flexibility.
The hw.uart.console and hw.uart.dbgport variables specify a list of
attributes. An attribute is a tag-value pair, seperated by a colon.
Attributes are seperated by a comma. Where possible, tags are the
same as those in /etc/remote (only br and pa in practice). Details
can be found in the manpage (not part of this commit).
Not tested on: amd64, pc98
