The creation and teardown of struct mem_cgroup is fairly messy and
that has attracted mistakes and subtle bugs before.
The main cause for this is that there is no clear model about what

Broadcom BCM963xx boards have multiple nvram variants across different
SoCs with additional checksum fields added whenever the size of the
nvram was extended.
Add this structure as a header file so that multiple drivers and userspace
can use it.

Use the common definition of the nvram structure from the header file
include/uapi/linux/bcm963xx_nvram.h instead of maintaining a separate
copy.
Read the version 5 size of nvram data from memory and then support the
version 4 and version 5 variants of nvram data checksums.

Hi Linus,
A set of fixes for the current series. This pull request contains:
- A bunch of fixes for lightnvm, should be the last round for this
series. From Matias and Wenwei.
- A writeback detach inode fix from Ilya, also marked for stable.
- A block (though it says SCSI) fix for an OOPS in

Add partitioning support for BCM963268 boards with CFE bootloaders.
The following partitions are defined:
"boot": CFE and nvram data
"rootfs": Currently selected rootfs
"data": Configuration data
"rootfs1_update": Container for the whole flash area used
