	sys/arch/x68k/x68k/disksubr.c: revision 1.36

Use a sane default for size of partition a: rather than odd 0x1fffffff.

The latter one seems derived from 386BSD (and 4.4BSD),
but it could confuse sysinst as noted in PR/55187.

Sync with most other modern ports that use secperunit
as well as RAW_PART.

	sys/arch/x68k/x68k/disksubr.c: revision 1.34
Fix buffer overrun in readdisklabel(9) (and writedisklabel(9))
that causes unexpected panic during installation and
DIAGNOSTIC pool assertions.
Also fix bp->b_flags in writedisklabel(9) error path.
The problem was reported from Y.Sugahara during XM6i development,
and this fix is confirmed on both X68030 (by me) and XM6i (by Sugahara).
XXX: broken dkbad support (which makes struct cpu_disklabel larger
XXX: than 512 bytes) should be removed...

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

Replace the myriad copies of bounds_check_with_label() with a single MI
version.

Add disk_blocksize(9) so that disk drivers can record the physical
block size of a disk if it is different to DEV_BSIZE. Right now this
simply initialises dk_blkshift and dk_byteshift according to the
supplied block size. This information is used in the MI version of
bounds_check_with_label().

Change bounds_check_with_label() to take a pointer to the disk structure,
rather than the label itself.  This paves the way for some future changes.

Change return type of readdisklabel() to const char *
I hope I've found all the correct places!

Nake return values from bounds_check_with_label() conform to the man
page: -1 for error, 0 for EOF, 1 otherwise. Inspired by an OpenBSD commit
message, pointed out by Miod Vallat in private mail.
vax/mba/hp.c: check return value <= 0, not < 0 to be concistent with how
other places handle return values from bounds_check_with_label().

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

rationalize the use of b_flags for geteblk() buffers.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

A foolish consistency; most parts of the kernel use bp->b_data, so
change these from bp->b_un.b_addr to bp->b_data, as well.  This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.

Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc.  Those
platforms should be changed to use device_register().  In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.

Mark LFS partitions as "BSD lfs ".
Now, swap partition should be "BSD swap" unless COMPAT_14.

Use b_cylinder as defined in sys/buf.h

Initial commit of recent changes to make DEV_BSIZE go away.

Runs on i386, needs work on other arch's. Main kernel routines should be
fine, but a number of the stand programs need help.

cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512
byte block devices. vnd, raidframe, and lfs need work.

Non 2**n block support is automatic for LKM's and conditional for kernels
on "options NON_PO2_BLOCKS".
