Add the ability to parse MTD partition information from the
kernel command line.
Note that a pointless BUG_ON is removed, as are redundant
calls to 'del_mtd_partitions()' and 'del_mtd_device()'
because they are also done by 'onenand_release()'.
Finally note that 'add_mtd_device()' returns 1 on failure
so the error condition was incorrect.

In checking for the ONFI revision, the first conditional (for checking
"unsupported" ONFI) seems unnecessary. All ONFI revisions should be
backwards-compatible; even if this is not the case on some newer ONFI
revision, it should simply fail the second version-checking if-else block
(i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we
move our "unsupported" condition after having checked each bit field.
Also, it's simple enough to add a condition for ONFI revision 2.3. Note
that this does *NOT* mean we handle all new features of ONFI versions
above 1.0.

We have the order of the conditional wrong for choosing the ONFI chip name
vs. the ID table name. Without this fix, we will almost *always* choose a
NULL string to print out instead of the correct one.
This has already been suggested by Matthieu Castet.

In its current form, the driver may interfere with different hardware on
different boards if built into the kernel, hence is not suitable for
inclusion into a defconfig, inteded to be usable with multiple OMAP1 cpu and
machine types.
Convert it to a platform driver, that should be free from this issue.
Created and tested against linux-2.6.37-rc5 on Amstrad Delta.

This reverts commit e14feafbe0d5c6d64bb6fe4eba928cb57ac9a4c8.
The commit limits the maximum amount of bytes which can be read
at one go to the OOB size, which is incorrect, because mtd->read_oob()
allows reading multiple pages at a time, see comment near
"struct mtd_oob_ops" at include/linux/mtd/mtd.h. So this patch
breaks ABI and hence, has to be reverted.

If the first htree directory is missing '.' or '..' but is otherwise a
valid directory, and we do a lookup for '.' or '..', it's possible to
dereference an uninitialized memory pointer in ext3_htree_next_block().
Avoid this.
We avoid this by moving the special case from ext3_dx_find_entry() to
ext3_find_entry(); this also means we can optimize ext3_find_entry()
slightly when NFS looks up "..".
Thanks to Brad Spengler for pointing a Clang warning that led me to
look more closely at this code. The warning was harmless, but it was
useful in pointing out code that was too ugly to live. This warning was
also reported by Roman Borisov.

An ext3 filesystem on a read-only device, with an external journal
which is at a different device number then recorded in the superblock
will fail to honor the read-only setting of the device and trigger
a superblock update (write).
For example:
- ext3 on a software raid which is in read-only mode
- external journal on a read-write device which has changed device num
- attempt to mount with -o journal_dev=<new_number>
- hits BUG_ON(mddev->ro = 1) in md.c

These patch fix a longstanding bug in the i810 frame buffer driver.
The handling of the i2c bus is wrong: A 1 bit should not written to the
i2c, these will be done by switch the i2c to input. Driving an 1 bit
active is against the i2c spec.
An active driven of a 1 bit will result in very strange error, depending
which side is the more powerful one. In my case it depends on the
temperature of the Display-Controller-EEprom: With an cold eprom a got
the correct EDID datas, with a warm one some of the 1 bits was 0 :-(
The same bug is also in the intelfb driver in the file
drivers/video/intelfb/intelfb_i2c.c. The functions intelfb_gpio_setscl()
and intelfb_gpio_setsda() do drive the 1 bit active to the i2c bus. But
since i have no card which is used by the intelfb driver i cannot fix
it.

Resurrected some old hardware and fixed up the hgafb driver to work
again. Only tested with fbcon, since most fbdev-based software appears
to only support 12bpp and up. It does not appear that this driver has
worked for at least the entire 2.6.x series, perhaps since 2002.
Hercules graphics hardware uses packed pixels horizontally, but rows are
not linear. In other words, the pixels are not packed vertically. This
means that custom imageblit, fillrect and copyarea need to be written
specific to the hardware.
* Removed the experimental acceleration option, since it is required
for the hardware to work.
* Fixed imageblit to work with fb_image's wider than 8 pixels.
* Updated configuration text (HGA hardware is from 1984)

This patch extends the LCDC driver with 24 bpp
and 32 bpp support.
These modes have been kept disabled earlier due
to dependencies between the potential two LCDC
channels that are exported as two separate
framebuffer devices. The dependency boils down
to a byte swap register that is shared between
multiple channels.
With this patch applied all single channel LCDC
hardware can chose freely from 16, 24 and 32 bpp.
Dual channel LCDC must stick to the same setup
for both channels.
Without this patch only 16 bpp is fully supported.

With cmwq, there's no reason for radeon to use a dedicated workqueue.
Drop dev_priv->wq and use system_wq instead.
Because radeon_driver_irq_uninstall_kms() may be called from
unsleepable context, the work items can't be flushed from there.
Instead, init and flush from radeon_irq_kms_init/fini().
While at it, simplify canceling/flushing of rdev->pm.dynpm_idle_work.
Always initialize and sync cancel instead of being unnecessarily smart
about it.

Acer laptop (TravelMate 5730G) has an HDMI connector
on the laptop and a DVI connector on the docking station
and both share the same encoder, hpd pin, and ddc line.
The bios connector table reflects this and is technically
correct, however, we drop the DVI connector here since
xrandr has no concept of encoders (only crtcs and connectors)
and will try and drive both connectors with different crtcs
which isn't possible on the hardware side and leaves no crtcs
for LVDS or VGA.

unix_release() can asynchornously set socket->sk to NULL, and
it does so without holding the unix_state_lock() on "other"
during stream connects.
However, the reverse mapping, sk->sk_socket, is only transitioned
to NULL under the unix_state_lock().
Therefore make the security hooks follow the reverse mapping instead
of the forward mapping.
