c573e654b7 Add OS layer ACPI mutex and threading support.
- Temporary fix a bug of Intel ACPI CA core code.
 - Add OS layer ACPI mutex support.  This can be disabled by
   specifying option ACPI_NO_SEMAPHORES.
 - Add ACPI threading support.  Now that we have a dedicate taskqueue for
   ACPI tasks and more ACPI task threads can be created by specifying option
   ACPI_MAX_THREADS.
 - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
   caller's buffer unless AE_BUFFER_OVERFLOW occurs.  Also CM battery's
   evaluations were changed to use acpi_EvaluateIntoBuffer().
 - Add new utility function acpi_ConvertBufferToInteger().
 - Add simple locking for CM battery and temperature updating.
 - Fix a minor problem on EC locking.
 - Make the thermal zone polling rate to be changeable.
 - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
   entering Debugger is easier to investigate the problem rather than panic.

1611ea8727 Add S4BIOS sleep (BIOS hibernation) and DSDT overriding support.
- Add S4BIOS sleep implementation.  This will works well if MIB
   hw.acpi.s4bios is set (and of course BIOS supports it and hibernation
   is enabled correctly).
 - Add DSDT overriding support which is submitted by takawata originally.
   If loader tunable acpi_dsdt_load="YES" and DSDT file is set to
   acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml),
   ACPI CA core loads DSDT from given file rather than BIOS memory block.
   DSDT file can be generated by iasl in ports/devel/acpicatools/.
 - Add new files so that we can add our proposed additional code to Intel
   ACPI CA into these files temporary.  They will be removed when
   similar code is added into ACPI CA officially.

683212b993 Some AML code assumes that a function without an explicit ReturnOp will
return the last value returned by a nested method call.  This violates
the ACPI spec, but is implemented by the Microsoft interpreter, and thus
vendors can (and do) get away with it.

Intel's stance is that this is illegal and should not be supported.
As they put it, however, we have to live in the real world.  So go ahead
and implement it.

d3abb52714 Some additional performance improvements. When freeing an inode
check to see if it has been committed to disk. If it has never
been written, it can be freed immediately. For short lived files
this change allows the same inode to be reused repeatedly.
Similarly, when upgrading a fragment to a larger size, if it
has never been claimed by an inode on disk, it too can be freed
immediately making it available for reuse often in the next slowly
growing block of the same file.

9626b608de Separate the struct bio related stuff out of <sys/buf.h> into
<sys/bio.h>.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.

Still a few bogus uses of struct buf to track down.

a64ed08955 Introduce extended attribute support for FFS, allowing arbitrary
(name, value) pairs to be associated with inodes.  This support is
used for ACLs, MAC labels, and Capabilities in the TrustedBSD
security extensions, which are currently under development.

In this implementation, attributes are backed to data vnodes in the
style of the quota support in FFS.  Support for FFS extended
attributes may be enabled using the FFS_EXTATTR kernel option
(disabled by default).  Userland utilities and man pages will be
committed in the next batch.  VFS interfaces and man pages have
been in the repo since 4.0-RELEASE and are unchanged.

o ufs/ufs/extattr.h: UFS-specific extattr defines
o ufs/ufs/ufs_extattr.c: bulk of support routines
o ufs/{ufs,ffs,mfs}/*.[ch]: hooks and extattr.h includes
o contrib/softupdates/ffs_softdep.c: extattr.h includes
o conf/options, conf/files, i386/conf/LINT: added FFS_EXTATTR

o coda/coda_vfsops.c: XXX required extattr.h due to ufsmount.h
(This should not be the case, and will be fixed in a future commit)

Currently attributes are not supported in MFS.  This will be fixed.

21144e3bf1 Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new
field in struct buf: b_iocmd.  The b_iocmd is enforced to have
exactly one bit set.

B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.

Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.

Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue.  It is likely to write on your disk
where it should have been reading.

This change is a step in the direction towards a stackable BIO capability.

A lot of this patch were machine generated (Thanks to style(9) compliance!)

57a91f6fb0 During fastpath processing for removal of a short-lived inode, the
set of restrictions for cancelling an inode dependency (inodedep)
is somewhat stronger than originally coded. Since this check appears
in two places, we codify it into the function check_inode_unwritten
which we then call from the two sites, one freeing blocks and the
other freeing directory entries.

4c6adb0622 Need to reorganize the flushing of directory entry (pagedep) dependencies
so that they never try to lock an inode corresponding to ".." as this
can lead to deadlock. We observe that any inode with an updated link count
is always pushed into its buffer at the time of the link count change, so
we do not need to do a VOP_UPDATE, but merely find its buffer and write it.
The only time we need to get the inode itself is from the result of a
mkdir whose name will never be ".." and hence locking such an inode will
never request a lock above us in the filesystem tree. Thanks to Brian
Fundakowski Feldman for providing the test program that tickled soft updates
into hanging in "inode" sleep.

7f473504e6 Free the global softupdates lock prior to tsleep() in getdirtybuf().
This seems to be responsible for a bunch of panics where the process
sleeps and something else finds softupdates "locked" when it shouldn't
be.  This commit is unreviewed, but has been a big help here.
Previously my boxes would panic pretty much on the first fsync() that
wrote something to disk.

1c2ceb2880 Because cylinder group blocks are now written in background,
it is no longer sufficient to get a lock on a buffer to know
that its write has been completed. We have to first get the
lock on the buffer, then check to see if it is doing a
background write. If it is doing background write, we have
to wait for the background write to finish, then check to see
if that fullfilled our dependency, and if not to start another
write. Luckily the explanation is longer than the fix.

94313add1f A panic occurs during an fsync when a dirty block associated with
a vnode has not been written (which would clear certain of its
dependencies). The problems arises because fsync with MNT_NOWAIT
no longer pushes all the dirty blocks associated with a vnode. It
skips those that require rollbacks, since they will just get instantly
dirty again. Such skipped blocks are marked so that they will not be
skipped a second time (otherwise circular dependencies would never
clear). So, we fsync twice to ensure that everything will be written
at least once.

cf60e8e4bf Several performance improvements for soft updates have been added:
1) Fastpath deletions. When a file is being deleted, check to see if it
   was so recently created that its inode has not yet been written to
   disk. If so, the delete can proceed to immediately free the inode.
2) Background writes: No file or block allocations can be done while the
   bitmap is being written to disk. To avoid these stalls, the bitmap is
   copied to another buffer which is written thus leaving the original
   available for futher allocations.
3) Link count tracking. Constantly track the difference in i_effnlink and
   i_nlink so that inodes that have had no change other than i_effnlink
   need not be written.
4) Identify buffers with rollback dependencies so that the buffer flushing
   daemon can choose to skip over them.

3f5b28bc07 Reorganize softdep_fsync so that it only does the inode-is-flushed
check before the inode is unlocked while grabbing its parent directory.
Once it is unlocked, other operations may slip in that could make
the inode-is-flushed check fail. Allowing other writes to the inode
before returning from fsync does not break the semantics of fsync
since we have flushed everything that was dirty at the time of the
fsync call.

6a4152243f The function request_cleanup() had a tsleep() with PCATCH. It is
quite dangerous, since the process may hold locks at the point,
and if it is stopped in that tsleep the machine may hang. Because
the sleep is so short, the PCATCH is not required here, so it has
been removed. For the future, the FreeBSD team needs to decide
whether it is still reasonable to stop a process in tsleep, as that
may affect any other code that uses PCATCH while holding kernel locks.

86b2c8466d Revamp the devstat priority system. All disks now have the same priority.
The same goes for CD drivers and tape drivers.  In systems with mixed IDE
and SCSI, devices in the same priority class will be sorted in attach
order.

Also, the 'CCD' priority is now the 'ARRAY' priority, and a number of
drivers have been modified to use that priority.

This includes the necessary changes to all drivers, except the ATA drivers.
Soren will modify those separately.

This does not include and does not require any change in the devstat
version number, since no known userland applications use the priority
enumerations.
