24c8525840 regulator: Fixes for v3.14
Mostly unexciting driver fixes, plus one fix to lower the severity of
 the log message when we don't use an optional regulator - the fixes for
 ACPI system made this come up more often and it was correctly observed
 that it was causing undue concern for users.

10762e8048 target/sbc: Fix sbc_dif_copy_prot addr offset bug
This patch fixes a bug in sbc_dif_copy_prot() where the updated addr
offset did not take into account the case where the associated
scatterlist had not been incremented.

This addresses the case where incoming protection scatterlists may
contain a length smaller than PAGE_SIZE across multiple entires,
when the target protection scatterlists are always being explicitly
filled up to PAGE_SIZE before adding another entry.

e1d8fb88a6 xfs: Add support FALLOC_FL_COLLAPSE_RANGE for fallocate
This patch implements fallocate's FALLOC_FL_COLLAPSE_RANGE for XFS.

The semantics of this flag are following:
1) It collapses the range lying between offset and length by removing any data
   blocks which are present in this range and than updates all the logical
   offsets of extents beyond "offset + len" to nullify the hole created by
   removing blocks. In short, it does not leave a hole.
2) It should be used exclusively. No other fallocate flag in combination.
3) Offset and length supplied to fallocate should be fs block size aligned
   in case of xfs and ext4.
4) Collaspe range does not work beyond i_size.

00f5e61998 fs: Add new flag(FALLOC_FL_COLLAPSE_RANGE) for fallocate
This patch is in response of the following post:
http://lwn.net/Articles/556136/
"ext4: introduce two new ioctls"

Dave chinner suggested that truncate_block_range
(which was one of the ioctls name) should be a fallocate operation
and not any fs specific ioctl, hence we add this functionality to new flags of fallocate.

This new functionality of collapsing range could be used by media editing tools
which does non linear editing to quickly purge and edit parts of a media file.
This will immensely improve the performance of these operations.
The limitation of fs block size aligned offsets can be easily handled
by media codecs which are encapsulated in a conatiner as they have to
just change the offset to next keyframe value to match the proper alignment.

In EXYNOS5 series SoCs, PMU has registers to enable/disable mask/unmask
watchdog timer which is not the case with s3c series SoCs so, there is a
need to have different compatible names for watchdog to handle these pmu
registers access.

Hence this patch removes watchdog node from Exynos5.dtsi common file and
make it separate by updating existing node in Exynos5250 and adding new node
to Exynos5420. This patch also makes the watchdog node enabled by default

bb38eefb68 mtd: nand: omap: fix ecclayout->oobfree->length
This patch excludes reserved-marker byte-position from oobfree->length
calculation. Thus all bytes from oobfree->offset till end of OOB are free.

aa6092f983 mtd: nand: omap: fix ecclayout->oobfree->offset
1) In current implementation, ecclayout->oobfree->offset is calculated with
 respect to ecclayout->eccpos[0] which is incorrect because ECC bytes may not
 be stored contiguously in OOB.
 So, this patch calculates ecclayout->oobfree->offset with respect to last
 ECC byte-position 'eccpos[ecclayout->eccbytes-1]'.

2) ECC layout of some ecc-schemes expects reserved-markers at specific eccpos[]
 which should not be over-written by any file-system metadata.
 So this patch aligns oobfree->offset taking into account of such markers.

eae39cb493 mtd: nand: omap: fix ecclayout to be in sync with u-boot NAND driver
Fixes: commit a919e51161
       mtd: nand: omap2: clean-up BCHx_HW and BCHx_SW ECC configurations in device_probe

Fixes ecclayout mismatch introduced in above commit for following ecc-schemes:
 - OMAP_ECC_BCH4_CODE_HW_DETECTION_SW
 - OMAP_ECC_BCH8_CODE_HW_DETECTION_SW
 However, this patch also touches other ecc-schemes as the fix required
 refactoring common code, into ecc-scheme specific code.

This patch aligns ecc-layout for below ecc-schemes as per reference [1],[2],[3]
