something snuck in here that wasn't supposed to be.

- Move the code that drops a ptp into a function and use that
in both pmap_do_remove and pmap_page_remove.
- In pmap_do_remove, instead of flushing the whole range from the tlb
at the same time, shoot one PDE at a time. It will allow us to skip
empty PDEs and reduces the amount of work one IPI has to do (although
we'll get more IPIs).

i.e. a similar scheme to audio(4) where the interface attaches on top of
the wildly different drivers. This helps to clean up the code a lot
(more is coming) and help me start to move drm to being essentially bus
independent, which will help in the future.

the policy for the mlock(2) on this architecture: all users are allowed
to call mlock, while the limit is imposed by the current RLIMIT_MEMLOCK
value.
"makes sense" art, ok hshoexer (who was running with the same change for
about 10 months).

In short, make cpu_unidle do what signotify used to do and
make signotify use cpu_unidle.
Also, include a cpu_unidle in need_resched, it won't change much right now
but will be needed in the future.

defines into real functions. since machdep.c is cluttered as it is move them
into bus_space.c (like amd64). a later commit will move the stuff from machdep
across too. since machdep.c is cluttered as it is move them into bus_space.c

previously, we had a static list of pcidevs and which agp driver would
be interanlly attached. Instead, split the agp drivers so they work like
audio(4), where we attach a driver, which sets up some callbacks and
initial state, then attaches the interface (agp(4)). Since this allows
us to attach different drivers in different places, and give them
/proper/ probe functions move most of the drivers back to attaching at
pchb, where they should, and intagp (formerly agp_i810) stays attaching
at vga, since it's part of the intel integrated graphics chips.
Diff shrinks the kernel slightly, gets rid of the annoying "no integrated
graphics" warning, and allows more cleanup later.
Tested by many. fix for alpha build (the only other vga_pci.c consumer)
suggested by miod.

values of the audio_params structure during AUDIO_SETINFO if the
hardware cannot be set to exactly the requested mode.
some drivers do this sometimes. others always return EINVAL if there
isn't an exact match.
be more consistent. only return EINVAL if an absurd parameter was
requested, otherwise return a supported set of parameters, as close
as possible to what was requested.

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.

and puts some backpressure on this process. come on, someone get mad...
and do something about it!
|

- 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
discussed with / requested by / testing theo, sthen@, djm@, jsg@,
merdely@, jsing@, tedu@, brad@, jakemsr@, and others.
looks good to millert@
