kernel thread of its own. the api has changed (which will be fixed in the
manpage shortly) so all the users of sensor tasks that i can find have
been fixed too.
noone tested, so its going in to force people to run with it.

cpu_disklabel can go away, since nothing anymore needs to use it; ok miod

Even if the latter would end up removing the mappings by itself, it would
do so using pmap_remove() because phys_map is not intrsafe; but some
platforms use pmap_kenter_pa() in vmapbuf(). By removing the mappings
ourselves, we can ensure the remove function used matches the enter function
which has been used.

to support hotplug media on most architectures. disklabel setup and
verification done using new helper functions. Disklabels must *always*
have a correct checksum now. Same code paths are used to learn on-disk
location disklabels, to avoid new errors sneaking in. Tested on almost all
cases, testing help from todd, kettenis, krw, otto, dlg, robert, gwk, drahn

routines (alpha, vax) prove to be not worth keeping. Move
bounds_check_with_label() into the MI world. Eliminate unreliable and
almost certainly useless checks for overwriting a disklabel.
After discussion with deraadt@
|
|
implimentations were simply either missing code, or spacing and such.
setdisklabel() can become MI now.

- always store our new fatty 16-partitions-with-full-cpg-info style
sun disklabels on the disk.
- correct an error in matching old-style 16-partition matching code;
the checksum spanned a different region

not to what some bogus disklabel from the past may say (some of which
may have been caused by older openbsd disklabel programs). resolves
issues seen by myself and Markus Lude on sparc/sparc64 machines

type of all variables to daddr64_t. this includes the APIs for XXsize()
and XXdump(), all range checks inside bio drivers, internal variables
for disklabel handling, and even uvm's swap offsets. re-read numerous
times by otto, miod, krw, thib to look for errors

accuracy so that the variious disksubr.c's can be compared easier.
setdisklabel() starts taking an int for openmask.

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.

next comes the type handling surrounding these values

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
|
|
readdisklabel(), since all readdisklabel()'s do that already.

bounds_check_with_label() routines as identical as possible without
changing any code. Code nits and adjustments to come.
|
|
|
|
disksort, not b_resid. b_cylinder is defined to be 'b_resid' so no
functional change.

store the information fsck needs. this allows us to create raid
partitions, nicely, of course.

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.
