instruction cache, also purge TLB entries. The PA-RISC 2.0
architecture says that cache lines may be moved in when a translation
exists even if no access is done. This might have been hurting us
badly since we create illegal aliases in pmap_zero_page() and
pmap_copy_page().
Probably not perfect yet, and perhaps a bit of a sledgehammer, but it
makes PA-RISC 2.0 machines stable again.

- 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

address space. The space between PAGE_SIZE and the non-pie fixed link
address creates no mmap pressure so use that space for PIE. However on
hppa the non-pie fixed link address is PAGE_SIZE so just use a small range
for PIE to minimize mmap pressure.

dino_intr_map(); rather than adding the missing cast, make the intent of
the code clearer by explicitenly testing for PCI_INTERRUPT_LINE being ff.
While there, enable the out-of-extent-range checks in dino_memmap() and
dino_memalloc() even if no option DEBUG, but return failure instead of
panicing.

after it was published. In particular, they changed the maximum cache
aliasing boundary from 1MB to 16MB.
It turns that on the PA-8700 the aliasing boundary is actually 4MB
(reported as such by the firmware at least). There are some comments
in the Linux code that suggest that HP never actually built PA-RISC
CPUs with an 8MB or 16MB aliasing boundary.
So raise the aliasing boundary to 4MB. This fixes the weird ps(1) problem
where it didn't print its own arguments correctly.

- 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).

gsckbd; the former will cause a proper translation page to be selected by
the keyboard.
Because of this, we no longer depend on the page the keyboard is left in
by the PDC (page 2 for all machines but the PrecisionBook, which is in
page 3), and there is no longer any need to use separate keyboard maps.

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.

alignment construct in the ld script, but it's too hot and too late to
do this correctly and I need a kernel that links (containing stuff to
reach a cvs tree near you reasonably soon).

file copies to nfsv2 causes the system to eventually peg the console.
On the console ^T indicates that the load is increasing rapidly, ddb
indicates many calls to getbuf, there is some very slow nfs traffic
making none (or extremely slow) progress. Eventually some machines
seize up entirely.

biowait() reads that do *not* come from the buffer cache - we use the
B_RAW flag to identify these at art's suggestion - since it makes sense
and the flag was not being used. this just flags all these buffers with
B_RAW - biodone already ignores returned buffers marked B_RAW.

reduce the footprint of the bsd.rd by shrinking the ramdisk filesystem
because it is way too large. tested by sthen and kettenis
