The new layout almost precisely matches FreeBSD, and should make
future imports much easier.
At the same time, import the current 0.9.16.16 HAL from FreeBSD. According
to sam@, this is the proper version we should be using.
modifies machine/db_machdep.h: BKPT_SET(inst) to BKPT_SET(inst, addr) for all archs ie; passess the
breakpoint address as well.
Patch from cherry@mahiti.org
arch/i386/conf/GENERIC, arch/i386/conf/files.i386 and dev/pci/files.pci which
can simply be uncommented to compile NDIS into the kernel. I'll write some
documentation on this soon.
Note that NDIS is still somewhat experimental. It is currently tested and
functions relatively well on on two cards:
1. Dell (Broadcom) TrueMobile 1400 Dual Band WLAN Mini-PCI
2. Intel EtherExpress Pro/100
ones and those for specific machines of developers. PR 32304.
OK'ed by rpaulo.
N.B. stf is a cloning device, so it still must be enabled by
"ifconfig stf0 create".

a shot at enabling thermal monitoring. On a Dell MP Xeon here, the
BIOS leaves the CPU out of spec. by not enabling thermal monitoring
at all. It looks like this code is not properly handling TM2 for
P-4 systems. Pentium-D and Pentium-4 systems enable TM2 differently.
I'm not sufficiently clued-up to deal with that at the moment.
To fix lingering problems with the LV/ULV Pentium Ms that run with a 400 MHz
FSB (738, et al), change ENTRY() yet again to directly include the FSB
multiplier - CPUID isn't enough to determine what it should be.
While I'm at it, add more values for the 750, and fix values for the 730
and 770 to jibe with what the 'prescribed' values (via ACPI) are.
Fixes PR/33080 and PR/33081.
Move the voltage-level check into the cpu ID loop, since it seems that
CPUs with the same ID string and the same CPUID can have different voltage
levels. Thank you, Intel.
FROMBCD()/TOBCD() macros into wrappers around it, resulting in both
smaller code footprint and elimination of possible issues due to
multiple evaluation of macro arguments.
Suggested by Simon Burge and Anders Gavare on tech-kern.
I had duplicated them. Improve the macros' names. Simplify their
implementation.
A brief description of each macro is below.
BIT(n): Return a bitmask with bit m set, where the least
significant bit is bit 0.
BITS(m, n): Return a bitmask with bits m through n, inclusive,
set. It does not matter whether m>n or m<=n.
The least significant bit is bit 0.
A "bitfield" is a span of consecutive bits defined by a
bitmask, where 1s select the bits in the bitfield. SHIFTIN,
SHIFTOUT, and SHIFTOUT_MASK help read and write bitfields
from device registers.
SHIFTIN(v, mask): Left-shift bits `v' into the bitfield
defined by `mask', and return them. No
side-effects.
SHIFTOUT(v, mask): Extract and return the bitfield selected
by `mask' from `v', right-shifting the
bits so that the rightmost selected bit
is at bit 0. No side-effects.
SHIFTOUT_MASK(mask): Right-shift the bits in `mask' so that
the rightmost non-zero bit is at bit
0. This is useful for finding the
greatest unsigned value that a bitfield
can hold. No side-effects. Note that
SHIFTOUT_MASK(m) = SHIFTOUT(m, m).

trace_is_enabled() to return TRUE if SYSCALL_DEBUG is defined, and g/c
all of the SYSCALL_DEBUG handling from individual system call dispatch
routines.
- proc_is_traced_p() -> trace_is_enabled(), to match trace_enter() and
trace_exit().
- trace_is_enabled() becomes a real function.
- Remove unnecessary include files from various files that used to care
about KTRACE and SYSTRACE, but do no more.
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
