distinction between signalling NaNs and quiet NaNs back into the
machine-dependent headers; treat the implementation of __nanf in the
same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.
in inline asm and include turning the DMMU off and back on. This
prevents the compiler (especially gcc -O0) from inserting accesses to
locations in virtual address space when such accesses would fail.
- don't use managed mappings/backing objects for wired memory allocations.
save some resources like pv_entry. also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.
to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz
supplied to bus_dmamap_create). dm_maxsegsz is reset to the value supplied to
bus_dmamap_create when the dmamap is unloaded.
(1) in pmap_enter_pv(), we would always mark the header entry wired, even if
the new entry wasn't put there. noticed by Juergen Hannken-Illjes.
(2) in pmap_unwire(), we would never examine the header entry.
noticed by me.
while I'm here, move the counter increment in the pmap_enter() path to be
next to the corresponding PV_WIRE() call so it's more obvious they match.
Rename consinit() to obs405_consinit() at evbppc/obs405/consinit.c.
Set md_consinit to obs405_consinit() at initppc().
Consinit fuction calls a function stored at md_consinit pointer.
Idle call that. Add a ci_idlespin function pointer to cpu_info.
Update INIT_CPUINFO to initialize it to a naked 'blr' instruction.
In oea/cpu_subr.c, add cpu_idlespin and make ci_idlespin point to it.
