Jaegeuk Kim b3d208f96d f2fs: revisit inline_data to avoid data races and potential bugs
This patch simplifies the inline_data usage with the following rule.
1. inline_data is set during the file creation.
2. If new data is requested to be written ranges out of inline_data,
 f2fs converts that inode permanently.
3. There is no cases which converts non-inline_data inode to inline_data.
4. The inline_data flag should be changed under inode page lock.

Jan Kara 1f7732fe6c f2fs: remove pointless bit testing in f2fs_delete_entry()
There's no point in using test_and_clear_bit_le() when we don't use the
return value of the function. Just use clear_bit_le() instead.

Jan Kara 9234f3190b f2fs: fix possible data corruption in f2fs_write_begin()
f2fs_write_begin() doesn't initialize the 'dn' variable if the inode has
inline data. However it uses its contents to decide whether it should
just zero out the page or load data to it. Thus if we are unlucky we can
zero out page contents instead of loading inline data into a page.

Jaegeuk Kim bce8d11207 f2fs: avoid deadlock on init_inode_metadata
Previously, init_inode_metadata does not hold any parent directory's inode
page. So, f2fs_init_acl can grab its parent inode page without any problem.
But, when we use inline_dentry, that page is grabbed during f2fs_add_link,
so that we can fall into deadlock condition like below.

Linus Torvalds 2084becbe1 ARM: SoC fixes for 3.8-rc3
A surprisingly small batch of fixes for -rc3. Suspiciously small, I'd say.
 
 Anyway, most of this are a few defconfig updates. Some for omap to deal
 with kernel binary size (moving ipv6 to module, etc). A larger one for
 socfpga that refreshes with some churn, but also turns on a few options
 that makes the newly-added board in my bootfarm usable for testing.
 
 OMAP3 will also now warn when booted with legacy (non-DT) boot protocols,
 hopefully encouraging those who still care about some of those platforms
 to submit DT support and report bugs where needed. Nothing stops working
 though, this is just to warn for future deprecation.
 
 Beyond this, very few actual bugfixes. A PXA fix for DEBUG_LL boot hangs,
 a missing terminting entry in a dt_match array on RealView a MTD fix on
 OMAP with NAND.

Linus Torvalds 81d92dc117 Three main MTD fixes for 3.18:
* A regression from 3.16 which was noticed in 3.17. With the restructuring of
    the m25p80.c driver and the SPI NOR library framework, we omitted proper
    listing of the SPI device IDs. This means m25p80.c wouldn't auto-load
    (modprobe) properly when built as a module. For now, we duplicate the device
    IDs into both modules.
 
 * The OMAP / ELM modules were depending on an implicit link ordering. Use
   deferred probing so that the new link order (in 3.18-rc) can still allow for
   successful probing.
 
 * Fix suspend/resume support for LH28F640BF NOR flash

Linus Torvalds ad2be3796f SCSI for-linus on 20141102
This is a set of six patches consisting of two MAINTAINER updates, two scsi-mq
 fixs for the old parallel interface (not every request is tagged and we need
 to set the right flags to populate the SPI tag message) and a fix for a memory
 leak in scatterlist traversal caused by a preallocation update in 3.17) and an
 ipv6 fix for cxgbi.

Olof Johansson 4257412db5 Few fixes for omaps to enable NAND BCH so devices won't
produce errors when booted with omap2plus_defconfig, and
 reduce bloat by making IPV6 a loadable module.
 
 Also let's add a warning about legacy boot being deprecated
 for omap3.
 
 We now have things working with device tree, and only omap3 is
 still booting in legacy mode. So hopefully this warning will
 help move the remaining legacy mode users to boot with device
 tree.
 
 As the total reduction of code and static data is somewhere
 around 20000 lines of code once we remove omap3 legacy mode
 booting, we really do want to make omap3 to boot also in
 device tree mode only over the next few merge cycles.
