right now that are supposed to be atomic with respect to interrupts and
SMP: atomic_setbits_int and atomic_clearbits_int.
All architectures other than i386 and amd64 get dummy implementations
since at first we'll be replacing operations that are done with
"a |= bit" and "a &= ~bit" today. More proper implementations will follow

use of MD spl code bowels. No functional change.

- it can really only be invoked from trap(), not from other userret() callers,
so it is safe to hardcode its docachepush parameter to 1.
- use pmap_kenter_pa()/pmap_kremove() for the temporary mapping instead of
pmap_enter()/pmap_remove().
optimize m68k userret():
- define PROC_PC for m68k systems.
- only check want_resched when processing T_ASTFLT traps.
- provide two version of userret(), one which will also invoke writeback()
on 68040 if required, which is only invoked from trap(), and regular
userret(). This speeds up system call returns.

to attach isabr if it really exists. This gets rid of ``isabr0 not configured''
messages on 425e.

Everything works well but interrupts, where no two devices causes the frodo
chip to behave in the same way... (polling will work nicely)

pointers, to be used for the various bus_space operations.
intio devices no longer need to pass an intiobase-relative address to
bus_space_map.

than having them build their own. No functional change.

instead of using the rom mapping for region #0 and the device mapping for
region #1. This will allow sti devices on which regions may be relative to
different origins to attach (to be used very soon).

existing alloc_attr function. This allows rasops_unpack_attr to be kept
private to rasops, yet available to the screen drivers.

driver to be able to tell how many wscons screens to attach to it,
instead of WSDISPLAY_DEFAULTSCREENS which is a global setting.

confusing when trying to attach scsibus to a hba, since it is really meant
for attaching scsi devices to scsibus.

them return 'invalid geometry' when d_secpercyl == 0. While there move
the check to a consistant location (after the check of d_secperunit)
and use a consistant idiom (i.e. some readdisklabel()'s have no 'done'
label).
prodded by thib@ after a bad macppc experience. ok deraadt@

writethrough on 68040.

removal of unused hil stuff, oversimplification of the stand ite code
(including dio frame buffer common code factorization), and sgc frame
buffer console support, at last.
This shaves ~1800 bytes off SYS_UBOOT and ~500 bytes of SYS_CDBOOT
despite the addition of the sgc code.
Tested on dca, hyper, topcat and sti.

setting RAW_PART's p_size to d_secperunit * (d_secsize / DEV_BSIZE) is
a waste of a few ops. And p_size should be in sectors anyway.
Just set RAW_PART's p_size to d_secperunit to make usage consistant
across the tree.
Should be a no-op.

or not, so that we can always feed them the complex operations before falling
back to rasops; and then topcat can perform coloured solid fills in
erase{cols,rows}.

no international keyboards to check I parse the right part of the string,
at least domestic keyboards are not affected; hinted at by the old X11R5
server.

days, simplify and inline more of it, to avoid doing unnecessary dest and/or
source loads. A copy of the old maskbits.h is moved to stand/ as the ite code
there needs the complete RR_ code.

this was inherited from sparc but this is not necessary on these platforms.

which bites the dust.

with the dummy wscons cngetc() which immediately returns zero. Since
a cngetc() call is the only difference between halt and reboot, this caused
the former to behave as the later. Fix this by spinning until cngetc() returns
a non-zero value.

- [DI]C{FL,PL,PP} and DCFA are only called on 680[46]0 systems and are
identical on these platforms, so don't bother checking for the MMU type.
- TBIAS is on 68060 codepath only.
- DCIAS, PCIA and TBIA are specific to some platforms and do not need to be
implemented everywhere.
