Linus removed the "volatile" statement from the definition of the
__raw_* IO accessors on ppc64, which cause some real bad optisations to
happen in some fbdev's like matroxfb to happen (just imagine that
matroxfb loops reading an IO register waiting for a bit to change).
The __raw_xxxx() functions still want ordered accesses (they avoid the
byteswap, though)

[PATCH] r8169: default on disabling PCIDAC
Default to disabling PCI DAC as this option appears unsafe on amd64
(original suggestion by Hans-Frieder Vogt <hfvogt@arcor.de>).
The driver will typically report PCI System error when something goes
wrong. The relevant interrupt is not masked any more and the driver
can thus be disabled.

[MMC] Clean up MMC card CID/CSD decoding, stage 1.
Now that the raw CSD and CID information are available in mmc_card,
there's little point not passing the mmc_card structure into the
decode functions themselves.
This will be necessary, since there's several different formats of
CID decode, and the format appears to depend on data in the CSD.
If we are unable to decode the CID or CSD, we can mark the card bad
and refuse to bind it to any drivers. Users can then retrieve the
raw undecoded CID and CSD from sysfs for debugging purposes.

[PATCH] device driver for the SGI system clock, mmtimer
SGI has been using this driver under Linux since 2001 but it was
never included in the upstream kernel. SuSE did include the patch for mmtimer
in SLES 9. The driver has been widely used for applications on the Altix
platform.
The timer hardware was designed around the multimedia timer specification by
Intel but to my knowledge only SGI has implemented that standard. The driver
was written by Jesse Barnes.
The second revision has interrupt support removed and was somewhat simplified
by removing one include file.

Currently metadata writing errors are ignored and not returned from
sys_fsync on ext2 and ext3 filesystems. That is, at least ext2 and ext3.
Both ext2 and ext3 resort to sync_inode() in their ->sync_inode method,
which in turn calls ->write_inode. ->write_inode method has void type, and
any IO errors happening inside are lost.
