for overwriting the disklabel. Reorder some checks so all copies of
bounds_check_with_label do the checks in the same order. Order picked
by using the currently most popular one. Should be no functional
change.

convert version 0 to version 1 disklabels.

subsystems were enabled. others used a *md_diskconf -> diskconf() method to
make sure init_main could "do late setroot". Change all architectures to
have diskconf(), use it directly & late. tested by todd and myself on most
architectures, ok miod too

1) Use local variable 'labelsector' not 'labelsect' to be consistant (hp300,
mac68k, mvme68k, mvme88k, vax).
2) Having checked for sz == 0, the next check needs only be sz < 0, not <= 0.
(mac68k, mvme68k, mvme88k)
3) Use lp->d_partitions + DISKPART(dev), rather than
lp->d_partitions[DISKPART(dev)] (hp300).
Assuming no typos there should be no functional change.

bounds_check_with_label() routines as identical as possible without
changing any code. Code nits and adjustments to come.

This changes nothing on legacy architectures, but is a bit faster (and simpler)
on the interesting ones.

free room in struct partition by packing fragment size and
fragments/block more tighlty and use the resulting space to make
offset and size 48 bits. For the disk part we use spare fields in
struct disklabel. Kernel converts in-mem copy of the on-disk
label if needed, disklabel(8) writes new version.
We are careful to only change fields not used by bootloaders.
Conception of basic scheme by deraadt.

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.

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.

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).
