This will enable uvm_map to behave intelligently when allocating.
Prodded by deraadt to commit this.

and display the symbol name if there is an exact match. The optimizer likes
to store addresses into `d' registers, then copy them to `a' registers and
invoke the function indirectly; previously we'd only get symbol lookup for
`lea' instructions (when storing to an `a' register).

change. It seems to have unexpected side effects, especially on MP systems,
and drahn@ disagrees with the way this change has been done and think there
is a better way to solve the original problem of msleep() fiddling with
mutex internals.

until they're zombies and then send them signals (for intr mounts). Until
that is untangled, the sigacts change is unsafe. sthen@ was the victim

be shared (p_sigignore, p_sigcatch, P_NOCLDSTOP, P_NOCLDWAIT) moves
to struct sigacts, wihle stuff that should be per rthread (ps_oldmask,
SAS_OLDMASK, ps_sigstk) moves to struct proc. Treat the coredumping
state bits (ps_sig, ps_code, ps_type, ps_sigval) as per-rthread
until our locking around coredumping is better.
Oh, and remove the old SunOS-compat ps_usertramp member.

always gaining anything, and msleep() implementation depends upon mtx_leave()

a vforked child behave correctly. Have the parent in a vfork()
wait on a (different) flag in *its* process instead of the child
to prevent a possible use-after-free. When ktracing the child
return from a fork, call it rfork if an rthread was created.

Okay guenther@, millert@.

a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument].
This allows MI drivers to implement mmap() routines without having to know
about the pmap_phys_address() implementation and #ifdef obfuscation.

for it. This makes the netisr a real C function which will help further
development. No noticable performance change on i386 and amd64.

vaddr_t PMAP_PREFER(..., vaddr_t). This allows better compiler optimization

it defines. In some cases, this means pulling in uvm.h or pcb.h
instead, but most of the inclusions were just noise. Tested on
alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax,
mostly by krw and naddy.

This is a noop on all arches but hp300, where this fixes (at least) IPL_BIO
mutexes.

landisk, and the sparc implementation is obviously wrong. That's where I
stopped looking, so who knows what else was broken. A simple comparison of
the existing mtx_enter with the new mtx_enter_try would have told anybody.

map to real hardware interrupt levels to have soft ipl values overlapping
hard ipl values without breaking spl asserts.

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)

anything special to prod a cpu to leave the idle loop in signotify.
powerpc, i386, amd64 and sparc64 will follow soon so that everyone has
the same interface to wake an idling cpu.
|
|
For now, sparc64 is arbitrarily set to 256 (only architecture that didn't have
a practical limit in the code on the number of cpus).

- 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@
