Pull MTD updates from Brian Norris:
 "Common MTD:

   - Add Kconfig option for keeping both the 'master' and 'partition'
     MTDs registered as devices.  This would really make a better
     default if we could do it over, as it allows a lot more flexibility
     in (1) determining the flash topology of the system from user-space
     and (2) adding temporary partitions at runtime (ioctl(BLKPG)).

     Unfortunately, this would possibly cause user-space breakage, as it
     will cause renumbering of the /dev/mtdX devices.  We'll see if we
     can change this in the future, as there have already been a few
     people looking for this feature, and I know others have just been
     working around our current limitations instead of fixing them this
     way.

   - Along with the previous change, add some additional information to
     sysfs, so user-space can read the offset of each partition within
     its master device

  SPI NOR:

   - add new device tree compatible binding to represent the
     mostly-compatible class of SPI NOR flash which can be detected by
     their extended JEDEC ID bytes, cutting down the duplication of our
     ID tables

   - misc.  new IDs

  Various other miscellaneous fixes and changes"

jffs2: allow to complete xattr integrity check on first GC scan

2012-05-14T04:32:36+00:00

Unlike file data integrity the xattr data integrity was not checked
before some explicit access to the attribute was made.

This could leave in the system a number of corrupted extended attributes
which will be detected only at access time and possibly at a very late
time compared to the time the corruption actually happened.

This patch adds the ability to check for extended attribute integrity
on first GC scan pass (similar to file data integrity check). This allows
for all present attributes to be completly verified before any use of them.

In order to work correctly this patch also needs the patch allowing
JFFS2 to discriminate between recoverable and non recoverable errors
on extended attributes.

jffs2: allow to discriminate between recoverable and non-recoverable errors

2012-05-14T04:30:34+00:00

This patch is basically a revert of commit f326966b3df47f4fa7e90425f60efdd30c31fe19.

It allows JFFS2 to make the distinction between a potential transient
error (reading or writing the media) and a non recoverable error like a
bad CRC on the extended attribute data or some insconsitent parameters.

In order to make clear that the error is indeed intended to report a
corrupted attribute, a new local error code (JFFS2_XATTR_IS_CORRUPTED)
is introduced rather than returning a confusing positive EIO, which is
what led to the inappropriate "fix" last time.

This error code is never reported to user space and only checked locally
in this file.

jffs2: Standardize JFFS_ uses

2012-03-26T23:42:14+00:00

Use pr_ to prefix KBUILD_MODNAME via pr_fmt.

Remove obfuscating defines and use constants in pr_
No need for a do {} while (0) for single statements.

"JFFS2 notice: " to "jffs2: notice: "

Added pr_fmt to xattr.c
