60794e0478 Centralize the devstat handling for all GEOM disk device drivers
in geom_disk.c.

As a side effect this makes a lot of #include <sys/devicestat.h>
lines not needed and some biofinish() calls can be reduced to
biodone() again.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

17661e5ac4 - Add an interlock argument to BUF_LOCK and BUF_TIMELOCK.
- Remove the buftimelock mutex and acquire the buf's interlock to protect
   these fields instead.
 - Hold the vnode interlock while locking bufs on the clean/dirty queues.
   This reduces some cases from one BUF_LOCK with a LK_NOWAIT and another
   BUF_LOCK with a LK_TIMEFAIL to a single lock.

e1df235292 Finally make vinum ready for the root filesystem in FreeBSD 5.x. (A
similar patch has been in 4.x for a while, but is more hacky there.)

For this to work, vinum has to be loaded early (e. g. from
boot/loader), for obvious reasons.  If the kernel env variable
(aka. loader variable) "vinum.autostart" is set, vinum then asks the
sysctl kern.disks for all available disks in the system, and scans
them for possible vinum headers.

For statically compiled kernels, this behaviour can be obtained even
without boot/loader by using "options VINUM_AUTOSTART" (though this is
not the recommended way).

Alternatively, the 4.x way to specify "vinum.drives" is also supported.

No further hacks (like the 4.x "vinum.root" variable) are needed,
since in 5.x, mountroot() asks back at the drivers to have them
resolve the name of the root FS into a dev_t (using the dev_clone
eventhandler).

(The MFC reminder below is for a partial MFC for vinum.autostart, the
rest is already there in 4.x.)

50be24a116 Explicitly cast daddr_t's to long long's when printing them since daddr_t
is not long long on all archs.  (They happen to be long's on 64-bit arch's
and gcc considers that significant enough to warn about it.)  These should
probably be uintmax_t but I didn't feel like adding all the extra includes.

6d4d944e33 Get Vinum up and running with GEOM:
(1) Use namei() and devfs to discover devices rather than a hard-coded
    MAKEDEV implementation.  Once rootfs is in place, this will allow
    Vinum to be used for the root file system partition.

(2) Pass FREAD to device opens so that GEOM will return sector size
    rather than an error on attempts to read label data.

(3) Avoid clobbering return values from close_drive() and masking this
    failure, resulting in a later divide by zero due to not having
    updated the Vinum-cached sector size.

(4) Ignore failures from DIOCWLABEL as that appears not to be required
    in the GEOM environment.

We've done testing in simple Vinum environments, but those with more
complex environments might want to give this a spin in DP2 and make
sure everything is up to speed.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

0d2af52141 Introduce the new 64-bit size disk block, daddr64_t. Change
the bio and buffer structures to have daddr64_t bio_pblkno,
b_blkno, and b_lblkno fields which allows access to disks
larger than a Terabyte in size. This change also requires
that the VOP_BMAP vnode operation accept and return daddr64_t
blocks. This delta should not affect system operation in
any way. It merely sets up the necessary interfaces to allow
the development of disk drivers that work with these larger
disk block addresses. It also allows for the development of
UFS2 which will use 64-bit block addresses.
