the CPU roles to compile on !MULTIPROCESSOR kernels and make the
top part of cpu_attach() which deals with processor setup depending
on the CPU role look much closer to the equivalent code for amd64.

which are uniform for the profclock on each cpu in a SMP system (but using
a different seed for each cpu). on all cpus, avoid seeding with a value out
of the [0, 2^31-1] range (since that is not stable)

It would be nice if someone with a "pci0 at mainbus0 bus 0: configuration 2"
system would double check this and mail us back.

- 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

512) bytes; ffs is inextricably tied to using b_blkno and disklabel
always uses sectorsize units.
Thus use DEV_BSIZE units for all fields describing ffs filesystems
and convert to/from sectors where required. This enables the creation
and use of ffs filesystems on non-512 byte sectorsize devices.
This diff allows i386 and sgi (the two test platforms) to find
disklabels that are not on a sectorsize boundary. Same change to
further archs coming.
This is a no-op on 512-byte sectorsize devices.
This work triggered by jsing@'s need to create ffs filesystems on
sgi cdroms so we can create cdrom install media for sgi.

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).

Intel don't publish the EST voltage tables, and they don't
even publish the MSRs for a shipping processor so we
can figure out how to do this in the backwards highest/lowest
way cleanly.
The mapping might look like the Core * one, but who really knows
for sure outside of a few guys at Intel. Other machines with
Atom processors and a different bus clock will have to be added
one by one until this stupidity changes.

* 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.

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!
