CPU_ENABLE_TCC enables Thermal Control Circuitry (TCC) found in some
Pentium(tm) 4 and (possibly) later CPUs. When enabled and detected,
TCC allows to restrict power consumption by using machdep.cpuperf*
sysctls. This operates independently of SpeedStep and is useful on
systems where other mechanisms such as apm(4) or acpi(4) don't work.
Given the fact that many, even modern, notebooks don't work properly
with Intel ACPI, this is indeed very useful option for notebook owners.

Fix some typos in the comment as well.
ubd_devinfo_vp() is getting an empty string from its usbd_get_string()
call on the vendor, instead of NULL. This means usb_knowndevs in not
consulted.
Add lines between grabbing those char *s and the USBVERBOSE ifdef to
set vendor to NULL if it is the empty string (similarly for product).
This causes vendor to be filled-out, although the product name read
overrules usb_knowndevs (this appears to be a conscience decision made
by the NetBSD folks):

This is a band-aide until the issues are better understood and the
issues with the lazy allocation patches are resolved.
Makes it possible to have multiple packet aliasing instances in a
single process by moving all static and global variables into an
instance structure called "struct libalias".
Redefine a new API based on s/PacketAlias/LibAlias/g
Add new "instance" argument to all functions in the new API.
Implement old API in terms of the new API.
This takes us a lot closer to refcounting dev_t.
This patch originally by cg@ with a few minor changes by me.
It is largely untested, but has been HEADSUP'ed twice, so presumably

file has been removed, it should be purged from the cache, but it need
not be removed from the directory stack causing corruption; instead,
it will simply be removed once the last references and holds on it
are dropped at the end of the unlink/rmdir system calls, and the
normal !UN_CACHED VOP_INACTIVE() handler for unionfs finishes it off.
This is easily reproduced by repeated "echo >file; rm file" on a
unionfs mount. Strangely, "echo -n >file; rm file" didn't make
it happen.
- Unify the conditional assignments section so that architectural
exclusions come first, sorted, then options and !options, sorted
by the option name, also in directory order, then architecture
specific sections, sorted by the architecture name, with i386
being a traditional exception.

According to the Windows DDK header files, KSPIN_LOCK is defined like this:
typedef ULONG_PTR KSPIN_LOCK;
From basetsd.h (SDK, Feb. 2003):
typedef [public] unsigned __int3264 ULONG_PTR, *PULONG_PTR;
typedef unsigned __int64 ULONG_PTR, *PULONG_PTR;
typedef _W64 unsigned long ULONG_PTR, *PULONG_PTR;
The keyword __int3264 specifies an integral type that has the following
properties:
+ It is 32-bit on 32-bit platforms
+ It is 64-bit on 64-bit platforms
+ It is 32-bit on the wire for backward compatibility.
It gets truncated on the sending side and extended appropriately
(signed or unsigned) on the receiving side.
Thus register_t seems the proper mapping onto FreeBSD for spin locks.
the definitions for NDIS_BUS_SPACE_IO and NDIS_BUS_SPACE_MEM logically
belong in hal_var.h. At least, that's my story, and I'm sticking to it.
Also, remove definition of __stdcall from if_ndis.c now that it's pulled
in from pe_var.h.
in OpenBSD by Niels Provos. The patch introduces a bitmap of allocated
file descriptors which is used to locate available descriptors when a new
one is needed. It also moves the task of growing the file descriptor table
out of fdalloc(), reducing complexity in both fdalloc() and do_dup().
Debts of gratitude are owed to tjr@ (who provided the original patch on
which this work is based), grog@ (for the gdb(4) man page) and rwatson@

of adding the code to lock and unlock the vnodes and taking care
to avoid deadlock, simplify linux_emul_convpath() by comparing the
vnode pointers directly instead of comparing their va_fsid and
va_fileid attributes. This allows the removal of the calls to
VOP_GETATTR().
This gives +10% performance on simple tests, so definitly worth it.
A few percent more could be had by not using M_ZERO'd alloc's, but
we then need to clear fields all over the place to be safe, and
that was deemed not worth the trouble (and it makes life dangerous).
be sure to increment the refcount of the argument so it is not

of the functions in libkern. Without this, parts of the kernel would
reference a non-existent (undeclared and undefined) ffs() function; the
only reason this didn't break the kernel build is that gcc happens to
have a built-in ffs() and incorrectly fails to warn about the lack of
prototypes for built-in functions.
ithread_remove_handler() may fail to remove the interrupt handler if
it decides to let the ithread do the removal. The problem is that during
boot "cold" is set, which causes msleep() to return immediately. This
will cause ithread_remove_handler() to fail to wait for the ithread
to do the removal from the handler TAILQ before freeing the handler
back to the heap. Bad things will happen when some other user of the
TAILQ, such as ithread_add_handler() or the actual ithread attempts to use
the freed handler. Fix the problem by forcing ithread_remove_handler()
to do the actual removal itself if the "cold" flag is set.

Add a reset function for host-end of the ATA channel. This is needed
for the SiI3112 in order to whack it back to reality if a device
locks up the SATA interface (thereby preventing that we can reset the
device). The result is that ATA now recovers from the timeouts that
happens with the SiI3112A and more or less all disks based on old
PATA electronics with a Marvell PATA->SATA converter. This includes
lots of the popular SATA dongles and the WDC Raptor disks..
