bd338d0708 ARM: S3C24XX: remove unneeded "config SMDK2440_CPU2442"
The Kconfig entry for SMDK2440_CPU2442 was moved from one Kconfig file
to another in commit acf2d41d85 ("ARM: S3C24XX: Move mach-s3c2440/
pll into mach-s3c24xx/"). In that move it also lost its statement to
select CPU_S3C2442. That was not needed anymore because it now depended
on that same symbol.

But without its select this entry became a nop: enabling it has no
effect, as it changes no code. It can safely be removed.

Fix a related, and trivial, comment typo too.

49b999711e ARM: EXYNOS: change HAVE_SAMSUNG_KEYPAD to KEYBOARD_SAMSUNG
Commit 6b5ab4f442 ("ARM: EXYNOS: Add Exynos4 device tree enabled
board file") added select HAVE_SAMSUNG_KEYPAD if INPUT_KEYBOARD

to the MACH_EXYNOS4_DT Kconfig entry. But there's no Kconfig symbol
HAVE_SAMSUNG_KEYPAD. Since this select statement depends on
INPUT_KEYBOARD this entry should select KEYBOARD_SAMSUNG instead.

ff588d83bf omapdss: features: fix supported outputs for OMAP4
The support outputs struct for overlay managers is incorrect for OMAP4. Make
these changes:

- DPI isn't supported via the LCD1 overlay manager, remove DPI as a supported
  output.
- the TV manager can suppport DPI, but the omapdss driver doesn't support that
  yet, we require some muxing at the DSS level, and we also need to configure
  the hdmi pll in the DPI driver so that the TV manager has a pixel clock. We
  don't support that yet.

a2f9b2a560 OMAPDSS: tpo-td043 panel: fix data passing between SPI/DSS parts
This driver uses omap_dss_device that it gets from a board file through
SPI platfrom_data pointer to pass data from SPI to DSS portion of the
driver by using dev_set_drvdata(). However this trick no longer works,
as DSS core no longer uses omap_dss_device from a board file to create
the real device, so use a global pointer to accomplish this instead,
like other SPI panel drivers do.

47bf379742 kvm/ppc/e500: eliminate tlb_refs
Commit 523f0e5421 ("KVM: PPC: E500:
Explicitly mark shadow maps invalid") began using E500_TLB_VALID
for guest TLB1 entries, and skipping invalidations if it's not set.

However, when E500_TLB_VALID was set for such entries, it was on a
fake local ref, and so the invalidations never happen.  gtlb_privs
is documented as being only for guest TLB0, though we already violate
that with E500_TLB_BITMAP.

Now that we have MMU notifiers, and thus don't need to actually
retain a reference to the mapped pages, get rid of tlb_refs, and
use gtlb_privs for E500_TLB_VALID in TLB1.

Since we can have more than one host TLB entry for a given tlbe_ref,
be careful not to clear existing flags that are relevant to other
host TLB entries when preparing a new host TLB entry.

78accda4f8 KVM: PPC: Added one_reg interface for timer registers
If userspace wants to change some specific bits of TSR
(timer status register) then it uses GET/SET_SREGS ioctl interface.
So the steps will be:
      i)   user-space will make get ioctl,
      ii)  change TSR in userspace
      iii) then make set ioctl.
It can happen that TSR gets changed by kernel after step i) and
before step iii).

To avoid this we have added below one_reg ioctls for oring and clearing
specific bits in TSR. This patch adds one registerface for:
     1) setting specific bit in TSR (timer status register)
     2) clearing specific bit in TSR (timer status register)
     3) setting/getting the TCR register. There are cases where we want to only
        change TCR and not TSR. Although we can uses SREGS without
        KVM_SREGS_E_UPDATE_TSR flag but I think one reg is better. I am open
        if someone feels we should use SREGS only here.
     4) getting/setting TSR register

d9abbf1c31 Btrfs: fix locking on ROOT_REPLACE operations in tree mod log
To resolve backrefs, ROOT_REPLACE operations in the tree mod log are
required to be tied to at least one KEY_REMOVE_WHILE_FREEING operation.
Therefore, those operations must be enclosed by tree_mod_log_write_lock()
and tree_mod_log_write_unlock() calls.

Those calls are private to the tree_mod_log_* functions, which means that
removal of the elements of an old root node must be logged from
tree_mod_log_insert_root. This partly reverts and corrects commit ba1bfbd5
(Btrfs: fix a tree mod logging issue for root replacement operations).

This fixes the brand-new version of xfstest 276 as of commit cfe73f71.

6113077cd3 Btrfs: fix missing qgroup reservation before fallocating
Steps to reproduce:
	mkfs.btrfs <disk>
	mount <disk> <mnt>
	btrfs quota enable <mnt>
	btrfs sub create <mnt>/subv
	btrfs qgroup limit 10M <mnt>/subv
	fallocate --length 20M <mnt>/subv/data

For the above example, fallocating will return successfully which
is not expected, we try to fix it by doing qgroup reservation before
fallocating.

835d974fab Btrfs: handle a bogus chunk tree nicely
If you restore a btrfs-image file system and try to mount that file system we'll
panic.  That's because btrfs-image restores and just makes one big chunk to
envelope the whole disk, since they are really only meant to be messed with by
our btrfs-progs.  So fix up btrfs_rmap_block and the callers of it for mount so
that we no longer panic but instead just return an error and fail to mount.
Thanks,

This is is needed as the private port data (including the wait queue

When switching to tty ports, some lifetime assumptions were changed.
Specifically, close can now be called before the final tty reference is
dropped as part of hangup at device disconnect. Even with the ftdi
private-data refcounting this means that the port private data can be
freed while a process is sleeping on modem-status changes and thus
cannot be relied on to detect disconnects when woken up.
