[PATCH] sparse: misc cleanups
all sorts of minor stuff - basically, all chunks are independent here,
but IMO that one is not worth splitting. Contains:
* pmac_cpufreq.c: declaration in the middle of a block.
* sys_ia32.c: couple of trivial annotations.
* ipmi_si_intf.c: should be using asm/irq.h instead of linux/irq.h
* synclink_cs.c: assignment-in-conditional with nobody ever looking
at the variable we are assigning to afterwards; variable removed.
* sbni.c: s/__volatile/__volatile__
* matroxfb_base.h: got rid of ((u32 *)p)++
* asm-ppc/checksum.h and asm-sparc64/floppy.h: NULL noise removal
* amd64 compat.h: missing L in long constant.
* mtd-abi.h: annotated ioctl structure
* sysctl.c: corrected annotations in extern

bte.c:
After working with the chip designer some more, we have determined one
more hardware register we were supposed to write to ensure the SHUB
chip was ready for future transfers. This patch fixes that. This also
allowed us to eliminate a udelay which was working around the problem.
During retesting, we uncovered a race condition where transfer status
was changed by a different cpu after we were expecting one value which
cascaded to additional problems. This patch uses a local variable to
also eliminate that race.

con_font_set() sanitized. We are passing console_font and flags into

We also do a sanity check (font width > 0) in the caller instead of

height <= 32 there; doesn't make sense leaving that one in method

[PATCH] con_font_op split
Preparations for cleanups: con_font_op() is turned into a switch calling
con_font_{get,set,default,copy} depending on the operation required;
method ->con_font_op() also split, with NULL resulting in -ENOSYS on
operation in question.
Code that used to be in con_font_op() got slightly cleaned up after move
into new helpers (we are beginning to untangle the mess; there will be
more cleanups in the next patches).
Methods are currently using exact same arguments as old ->con_font_op().
That will change in subsequent patches, method by method (right now there's
a hell of a scary field reuse between them, making impossible to do any
static checks and practically begging for bugs).

[PATCH] writepages drops bh on not uptodate page
I think I understood why some ext2 fs corruption still happens even after
the last i_size fix.
what happened I believe is that the writepages layer got a not a fully
uptodate page (in turn with bh mapped on top of it), and then right before
unlocking the page and entering the writeback mode, it freed all the bh.
Without bh a not uptodate page will trigger a full readpage from disk, that
overwrites the pagecache before the multi-bio gets submitted, generating fs
corruption.
I believe the below patch should fix it (untested) against kernel CVS.
The testcases developed by Kurt showed the pagecache being overwritten with
on-disk data at block offsets, and Chris as well was wondering about races
between wait_on_page_writeback and readpage. the below fix just explains
everything we've seen since not-fully-uptodate pages must have always bh on
them and the below patch enforces just that invariant, and it should fix
our pagecache-overwritten-by-disk-data problem.

[PATCH] Add documentation about /proc/sys/vm/laptop_mode to various docs.
From: Bart Samwel <bart@samwel.tk>
A bunch of small laptop mode updates:
* Mention the laptop_mode and block_dump sysctls in the relevant docs,
referring to the laptop-mode.txt. Improve description of what the
laptop_mode knob means (i.e. seconds between last I/O and automatic
sync).
* Document the most relevant config file options.
* Change the installation instructions in the laptop mode doc to describe
the ACPI-bound version first, because this is the easiest. Explain
the non-ACPI version afterwards. Added a reference to my "packaged
version" of the scripts.
* Move the setting of hdparm and cpu frequency out of the ACPI script
and into the core laptop mode script. Add config option DO_HD to
enable hdparm. Add config setting HD to set device to do hdparm on.
Rename Dax's CPU_MANAGE to DO_CPU, with 0/1 instead of yes/no, to
improve consistency.
* Fix a problem where the root filesystem wouln't be remounted when
/etc/mtab listed its type as "unknown". Deduce the type of "unknown"
filesystems from /etc/fstab.
This depends on the patch that adds config files, which was submitted
to Linus by Dax Kelson on July 10.
Add support for a external configuration file for /sbin/laptop_mode, and
/etc/acpi/actions/battery.sh. Convert battery.sh to use CPUFreq (off by
default) instead of CPU throttling (that was off by default).
Cleanup some formating for 80 columns.
All changes were written by me on a plane flight from Philadelphia to Salt
Lake City on July 9th. :)
(Note from Bart Samwel: was submitted to Linus earlier, this patch is
unchanged from that. I needed to submit this into -mm for now because my
other changes are dependent on Dax's changes.)
