This was brought over from UMS, and used for a while until we decided
that drm_helper_resume_force_mode was easier and more reliable, since
it didn't require duplicating all the code deleted here.  We just
forgot to delete all that junk for a while.

This one replaces original param for intel_ddc_get_modes() with
DRM connector and i2c bus adapter instead. With explicit params,
we won't require that a single driver structure must hold connector
and DDC bus reference, which ease the conversion to splitted encoder/
connector model.

It also clears up for some cases that we would steal other DDC bus
for mode probe, like VGA analog DDC probe for DVI-I. Also it fixed
a bug in old DVI-I probe handling, that failed to restore origin
analog GPIO port.

In load detection, connector's encoder assignment must be kept

The TV detection logic is not reliable on the Cantiga platform.
Sometimes the TV will be misdetected as the following two cases:
- TV is misdetected on some laptops. e.g. There is no TV connector
port or no TV is attached. But the TV is shown as connected.
- TV connector type is misdetected. e.g. the component TV is
attached, but the TV is shown as S-video type.

According to the hardware requirement, the TV sense state bits of TV DAC
register should be cleared to zero on Cantiga platfrom.

The intel_output naming is inherited from the UMS code, which had a
structure of screen -> CRTC -> output.  The DRM code has an additional
notion of encoder/connector, so the structure is screen -> CRTC ->
encoder -> connector.  This is a useful structure for SDVO encoders
which can support multiple connectors (each of which requires
different programming in the one encoder and could be connected to
different CRTCs), or for DVI-I, where multiple encoders feed into the
connector for whether it's used for digital or analog.  Most of our
code is encoder-related, so transition it to talking about encoders
before we start trying to distinguish connectors.

In order to use disks larger than 2TiB on Windows XP, it is necessary to
use 4096-byte logical sectors in an MBR.

Although the kernel storage and functions called from msdos.c used
"sector_t" internally, msdos.c still used u32 variables, which results in
the ability to handle XP-compatible large disks.

This patch changes the internal variables to "sector_t".

In the extended CSD register the CARD_TYPE is an 8-bit value of which the
upper 6 bits were reserved in JEDEC specifications prior to version 4.4.
In version 4.4 two of the reserved bits were designated for identifying
support for the newly added High-Speed Dual Data Rate.  Unfortunately the
mmc_read_ext_csd() function required that the reserved bits be zero
instead of ignoring them as it should.

This patch makes mmc_read_ext_csd() ignore the CARD_TYPE bits that are
reserved or not yet supported.  It also stops the function jumping to the
end as though an error occurred, when it is only warns that the CARD_TYPE
bits (that it does interpret) are invalid.

The reiserfs journal behaves inconsistently when determining whether to
allow a mount of a read-only device.

This is due to the use of the continue_replay variable to short circuit
the journal scanning.  If it's set, it's assumed that there are
transactions to replay, but there may not be.  If it's unset, it's assumed
that there aren't any, and that may not be the case either.

I've observed two failure cases:
1) Where a clean file system on a read-only device refuses to mount
2) Where a clean file system on a read-only device passes the
   optimization and then tries writing the journal header to update
   the latest mount id.

The former is easily observable by using a freshly created file system on
a read-only loopback device.

This patch moves the check into journal_read_transaction, where it can
bail out before it's about to replay a transaction.  That way it can go
through and skip transactions where appropriate, yet still refuse to mount
a file system with outstanding transactions.

Commit 57fe60df ("reiserfs: add atomic addition of selinux attributes

mounting a file system that didn't previously contain extended attributes
on a system using security.* xattrs.

The issue is that while creating the privroot during mount
reiserfs_security_init calls reiserfs_xattr_jcreate_nblocks which
dereferences the xattr root.  The xattr root doesn't exist, so we get an
oops.

In 2.6.34-rc1, removing vhost_net module causes an oops in sync_mm_rss
(called from do_exit) when workqueue is destroyed.  This does not happen
on net-next, or with vhost on top of to 2.6.33.

The issue seems to be introduced by
34e55232 ("mm: avoid false sharing of
mm_counter) which added sync_mm_rss() that is passed task->mm, and
dereferences it without checking.  If task is a kernel thread, mm might be
NULL.  I think this might also happen e.g.  with aio.

This patch fixes the oops by calling sync_mm_rss when task->mm is set to
NULL.  I also added BUG_ON to detect any other cases where counters get
incremented while mm is NULL.

The oops I observed looks like this:
