Having them 'hlt' is a good thing, especially
where thermal management (acpi, etc) is concerned.
They wake up lots due to local tick timer anyhow.

- provide proper dtoa locks
- use the real strtof implementation
- add strtold, __hdtoa, __hldtoa
- add %a/%A support
- don't lose precision in printf, don't round to double anymore
- implement extended-precision versions of libc functions: fpclassify,
isnan, isinf, signbit, isnormal, isfinite, now that the ieee.h is
fixed
- separate vax versions of strtof, and __hdtoa
- add complex math support. added functions: cacos, casin, catan,
ccos, csin, ctan, cacosh, casinh, catanh, ccosh, csinh, ctanh, cexp,
clog, cabs, cpow, csqrt, carg, cimag, conj, cproj, creal, cacosf,
casinf, catanf, ccosf, csinf, ctanf, cacoshf, casinhf, catanhf,
ccoshf, csinhf, ctanhf, cexpf, clogf, cabsf, cpowf, csqrtf, cargf,
cimagf, conjf, cprojf, crealf
- add fdim, fmax, fmin
- add log2. (adapted implementation e_log.c. could be more acruate
& faster, but it's good enough for now)
- remove wrappers & cruft in libm, supposed to work-around mistakes
in SVID, etc.; use ieee versions. fixes issues in python 2.6 for
djm@
- make _digittoint static
- proper definitions for i386, and amd64 in ieee.h
- sh, powerpc don't really have extended-precision
- add missing definitions for mips64 (quad), m{6,8}k (96-bit) float.h
for LDBL_*
- merge lead to frac for m{6,8}k, for gdtoa to work properly
- add FRAC*BITS & EXT_TO_ARRAY32 definitions in ieee.h, for hdtoa&ldtoa
to use
- add EXT_IMPLICIT_NBIT definition, which indicates implicit
normalization bit
- add regression tests for libc: fpclassify and printf
- arith.h & gd_qnan.h definitions
- update ieee.h: hppa doesn't have quad-precision, hppa64 does
- add missing prototypes to gdtoaimp
- on 64-bit platforms make sure gdtoa doesn't use a long when it
really wants an int
- etc., what i may have forgotten...
- bump libm major, due to removed&changed symbols
- no libc bump, since this is riding on djm's libc major crank from
a day ago

This requires that structures defined within __packed structures must
independently request that they themselves become __packed, too.

This "power saving" disables the apic when both cpu cores hit the hlt

we depended on the pageability of the kernel_map to map them which worked
most of the time, until we hit the most improbable case - when cpu_switchto
wanted to fault in the missing gdt page, which at this moment is Verboten.

- math.h shouldn't define FLT_EVAL_METHOD, but float.h should (per
C99). remove from math.h, and add proper definitions in float.h

Right now when mi_switch picks up the same proc, we didn't clear the
flag which would mean that every time we service an AST we would attempt
a context switch. For some architectures, amd64 being probably the
most extreme, that meant attempting to context switch for every
trap and interrupt.
Now we clear_resched explicitly after every context switch, even if it
didn't do anything. Which also allows us to remove some more code
in cpu_switchto (not done yet).

parameter and returns an aligned random load address for position
independent executables to use. This also adds three new vmparam.h
defines to specify the maximum address, minimum address and minimum
allowed alignment for uvm_map_pie() to use. The PIE address range
for i386 was carefully selected to work well within the i386 W^X
framework.
With much help and feedback from weingart@.

For now, only one such flag is defined, PCKBC_CANT_TRANSLATE. It hints
pckbc that the device does not behave correctly to the ``set translation''
commands.
Set this flag if we are running on a Tadpole Ultrabook machine, which needs it.
This makes the built-in keyboard work correctly on this laptop (with the
help of the software translation pckbd diff).

* For amd64, remove pcibios traces.
* make RBUS_IO_START, RBUS_IO_SIZE, RBUS_MIN_START and RBUS_MEM_SIZE
(on i386) configurable via kernel options.
* Remove unneeded headers.
* Some cleanups.

kettenis@ and miod@ agrees that although not perfect, this is the right
direction.

k8pnow_transition handles the actual transition, this change is
necessitated by some of the ACPI work which can involve dynamic changes
in the available states in response to endogenous events such as removing
the AC power. This new code is designed to cope with the current operating
point not being among the newly available states in which case we
recalculate what the current desired performance level coresponds to among
the new states.
Also fix a screw up with the acpi_states function (fix originally by
Markus Hennecke in a diff to tech@ thanks) which resolves PR 5854. Diff
tested by numerous people thanks!

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

(EDD) is found and OK. it will also fix chainloading into OpenBSD from
grub in a few scenarios where grub doesn't report the CHS correctly
but the LBA. and we don't need CHS if there is LBA.

extended DOS partition. the concept of extended partitions is very
simple, it is just another mbr at the partition offset (well, the
standard "EBR" is a linked list with a few limitations, but this diff
works with both variants).

track of where it was up to when building dmamaps. that lastaddr variable
is not initialised every time you start to load a dmamap, so it was using
random stack garbage as state when first writing the sg list.
fortunately the way it was used meant it was extremely unlikely to cause a
problem, but why allow even that possibility? this inits lastaddr to 0 in
all the callers of load_buffer.
