device_register() function -- even if it does nothing. reduces the
cpp-based blather different between architectures
idea ok'd by miod; tested on all architectures (except a few miod will
need to cleanup because he has them)

it's a good idea to use atomic.h operations on it. This mechanic
change updates all bit operations on p_flag to atomic_{set,clear}bits_int.
Only exception is that P_OWEUPC is set by MI code before calling
need_proftick and it's automatically cleared by ADDUPC. There's
no reason for MD handling of that flag since everyone handles it the
same way.

- reset the drive and fetch its identification strings during probe, and do
not attach if they don't look good.
- do not store synchronous command blocks (used by hdreset) in the softc,
since they are not processed asynchronously. The stack will do.
- cleanup the disklabel retrieval code.
- use disk_{,un}lock instead of rolling our own equivalent.
- use bounds_check_with_label() in hdstrategy() instead of a stripped-down
inline version of it.
Tested on 7957A.

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''

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

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).

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@

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.
