In bdi_position_ratio(), get difference (setpoint-dirty) right even when
negative. Both setpoint and dirty are unsigned long, the difference was
zero-padded thus wrongly sign-extended to s64. This issue affects all
32-bit architectures, does not affect 64-bit architectures where long
and s64 are equivalent.

In this function, dirty is between freerun and limit, the pseudo-float x
is between [-1,1], expected to be negative about half the time. With
zero-padding, instead of a small negative x we obtained a large positive
one so bdi_position_ratio() returned garbage.

Casting the difference to s64 also prevents overflow with left-shift;
though normally these numbers are small and I never observed a 32-bit
overflow there.

(This patch does not solve the PAE OOM issue.)

writeback_inodes_sb(_nr)_if_idle() is re-implemented by replacing down_read()
with down_read_trylock() because

- If ->s_umount is write locked, then the sb is not idle. That is
  writeback_inodes_sb(_nr)_if_idle() needn't wait for the lock.

- writeback_inodes_sb(_nr)_if_idle() grabs s_umount lock when it want to start
  writeback, it may bring us deadlock problem when doing umount. In order to
  fix the problem, ext4 and btrfs implemented their own writeback functions
  instead of writeback_inodes_sb(_nr)_if_idle(), but it introduced the redundant
  code, it is better to implement a new writeback_inodes_sb(_nr)_if_idle().

The name of these two functions is cumbersome, so rename them to
try_to_writeback_inodes_sb(_nr).

This idea came from Christoph Hellwig.
Some code is from the patch of Kamal Mostafa.

With commit 384a2902 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.

Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

Merge branch 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Summary:
- change exynos file license
  . Most of exynos files had been copied from some randome
    file and not updated correctly(wrong company name used).
    This was our mistakes so chagnes it correctly. For this,
    I'm not sure that this patch should go to -fix or -next.
    So please give me any comment if there is any problem.
- consider buffer allocation without iommu
  . Without iommu, dma_alloc_attrs function allocates some
    memory region and returns cpu address so this patch makes
    the cpu address to be set to buf->kvaddr correctly
- cleanups to ipp relevant codes.
- use common finish page flip function
  . to avoid the duplication of same code, use
    exynos_drm_crtc_finish_pageflip function commonly instead
    of each one.
- fix fimd resume issue.
  . when fimd was turned off by suspend, there was one issue that
    the fimd wasn't turned on by resume so fix it chaing resume
    condition.

 "Misc small cifs fixes"

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
  CIFS: Don't let read only caching for mandatory byte-range locked files
  CIFS: Fix write after setting a read lock for read oplock files
  Revert "CIFS: Fix write after setting a read lock for read oplock files"
  cifs: adjust sequence number downward after signing NT_CANCEL request
  cifs: move check for NULL socket into smb_send_rqst

The IRQ array must be terminated by -1 and not by -1+OMAP_INTC_START
This led to having a resource list of 100s of IRQs.

Looks like this was caused by commit a2cfc509 (ARM: OMAP3+: hwmod: Add
AM33XX HWMOD data) that probably had some search and replace updates
done for the patch for sparse irq support.

Pull namei.h missing include fix from Al Viro.

The new use of ESTALE in namei.h can cause compile failures on ARM with
certain configurations due to lack of errno.h.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  namei.h: include errno.h

Commit 0d0863b0 ("sctp: Change defaults on cookie hmac selection")
added a "choice" to the sctp Kconfig file.  It introduced a bug which
led to an infinite loop when while running "make oldconfig".

The problem is that the wrong symbol was defined as the default value
for the choice.  Using the correct value gets rid of the infinite loop.

Note:  if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input
config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present
in the generated config file.

Pull ext4 regression fixes from Ted Ts'o:

  serious of these regressions is a buffer cache leak."

* tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
  ext4: remove duplicate call to ext4_bread() in ext4_init_new_dir()

Use device_unregister to replace put_device + device_del for
cleanup, and fix the potential use after free.

After f65aad41("MIPS: Cavium: Add EDAC support."), when entering
the "Device Drivers" toplevel menu in menuconfig, the suboptions behind
EDAC appeared merged with the rest of the device drivers types. This was
because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig
bool which was defined after the menu definition.

When pushing EDAC_SUPPORT up, before the menu definition, the variable
is defined earlier and the above menuconfig artifact doesn't happen.

Drop a useless menuconfig comment while at it.

This patch fixes use-after-free and double-free bugs in
edac_mc_sysfs_exit(). mci_pdev has single reference and put_device()
calls mc_attr_release() which calls kfree(). The following
device_del() works with already released memory. An another kfree() in
edac_mc_sysfs_exit() releses the same memory again. Great.
