Mixing putchar() and write() hvcalls does not work %100

We need to make sure the MD update occurs before we try to
process dr-cpu configure requests. MD update and dr-cpu
were being processed by seperate threads so that did not
happen occaisionally.
Fix this by executing all domain services data packets from
a single thread, in order.
This will help simplify some other things as well.

The SCSI code can be compiled modular, but BLK_DEV_BSG currently cannot,
and depends on the SCSI layer. So make sure that it depends on the SCSI
layer being compiled in, not just available as a module.

This reverts commit 29578624e354f56143d92510fff33a8b2aaa2c03.
Ingo Molnar reports complete breakage with his e1000 card (no
networking, card reports transmit timeouts), and bisected it down to
this commit. Let's figure out what went wrong, but not keep breaking

Teach LDM about a new field encountered with Windows Vista.
This fixes LDM for people using Vista who have disabled drive letter
assignment from one or more volumes. Doing this introduces a so far
unknown field in the LDM database in the VOL5 VBLK structure which
causes the LDM driver to fail to parse the VBLK structure and hence LDM
fails to parse the disk altogether. This patch teaches the driver about
this field.
Thanks got to Ashton Mills <amills@iinet.com.au> for reporting the
problem and working with me on getting it fixed. It is now working for
him.

FAT12 entry is 12bits, so it needs 2 phase to update the value. And
writer and reader access it without any lock, so reader can get the
half updated value.
This fixes the long standing race condition by adding a global
spinlock to only FAT12 for avoiding any impact against FAT16/32.

This is a patch that speeds up statfs. It is very simple - the "overhead"
calculation, which takes a huge amount of time for large filesystems, never
changes unless the size of the filesystem itself changes. That means we can
store it in memory and only recalculate if the filesystem has been resized
(almost never).
It also fixes a minor problem that we never update the on-disk superblock free
blocks/inodes counts until the filesystem is unmounted. While not fatal, we
may as well update that on disk when we have the information, and it makes
things like debugfs and dumpe2fs report a bit more accurate info.

Optimize integer-to-string conversion in vsprintf.c for base 10. This is
by far the most used conversion, and in some use cases it impacts
performance. For example, top reads /proc/$PID/stat for every process, and
with 4000 processes decimal conversion alone takes noticeable time.
Using code from
http://www.cs.uiowa.edu/~jones/bcd/decimal.html
(with permission from the author, Douglas W. Jones)
binary-to-decimal-string conversion is done in groups of five digits at
once, using only additions/subtractions/shifts (with -O2; -Os throws in
some multiply instructions).
On i386 arch gcc 4.1.2 -O2 generates ~500 bytes of code.
This patch is run tested. Userspace benchmark/test is also attached.
I tested it on PIII and AMD64 and new code is generally ~2.5 times
faster. On AMD64:
# ./vsprintf_verify-O2
Original decimal conv: .......... 151 ns per iteration
Patched decimal conv: .......... 62 ns per iteration
Testing correctness
12895992590592 ok... [Ctrl-C]
# ./vsprintf_verify-O2
Original decimal conv: .......... 151 ns per iteration
Patched decimal conv: .......... 62 ns per iteration
Testing correctness
26025406464 ok... [Ctrl-C]
More realistic test: top from busybox project was modified to
report how many us it took to scan /proc (this does not account
any processing done after that, like sorting process list),
and then I test it with 4000 processes:
#!/bin/sh
i=4000
while test $i != 0; do
sleep 30 &
let i--
done
busybox top -b -n3 >/dev/null
on unpatched kernel:
top: 4120 processes took 102864 microseconds to scan
top: 4120 processes took 91757 microseconds to scan
top: 4120 processes took 92517 microseconds to scan
top: 4120 processes took 92581 microseconds to scan
on patched kernel:
top: 4120 processes took 75460 microseconds to scan
top: 4120 processes took 66451 microseconds to scan
top: 4120 processes took 67267 microseconds to scan
top: 4120 processes took 67618 microseconds to scan
The speedup comes from much faster generation of /proc/PID/stat
by sprintf() calls inside the kernel.

* There is no point in having full "0...9a...z" constant vector,
if we use only "0...9a...f" (and "x" for "0x").
* Post-decrement usually needs a few more instructions, so use
pre decrement instead where makes sense:
- while (i < precision--) {
+ while (i <= --precision) {
* if base != 10 (=> base 8 or 16), we can avoid using division
in a loop and use mask/shift, obtaining much faster conversion.
(More complex optimization for base 10 case is in the second patch).
Overall, size vsprintf.o shows ~80 bytes smaller text section
with this patch applied.

In drivers/pnp/isapnp/core.c::isapnp_read_tag() there is a test of 'type'
being == 0 a bit down in the function. That test doesn't make any sense.
If 'type' could indeed be NULL, then the test happens way too late as we'd
already have tried to dereference the pointer earlier and looking at the
callers it also turns out that there is no way type can ever actually be
NULL.
So the test is completely pointless and should just be removed.

kernel/printk.c: document possible deadlock against scheduler
The printk's comment states that it can be called from every context,
which might lead to false illusion that it could be called from everywhere
without any restrictions.
This is however not true - a call to printk() could deadlock if called from
scheduler code (namely from schedule(), wake_up(), etc) on runqueue lock
when it tries to wake up klogd. Document this.
