nfs_page_find_head_request_locked looks through the regular nfs commit lists
when the page is swapped out, but doesn't look through the pnfs commit lists.

Fix the endianness handling in gss_wrap_kerberos_v1 and drop the memset
call there in favor of setting the filler bytes directly.
In gss_wrap_kerberos_v2, get rid of the "ec" variable which is always
zero, and drop the endianness conversion of 0. Sparse handles 0 as a
special case, so it's not necessary.

The handling of the gc_ctx pointer only seems to be partially RCU-safe.
The assignment and freeing are done using RCU, but many places in the
code seem to dereference that pointer without proper RCU safeguards.
Fix them to use rcu_dereference and to rcu_read_lock/unlock, and to
properly handle the case where the pointer is NULL.

Commit 5b22216e11f7 (nfs: __rcu annotations) added a __rcu annotation to
the gc_gss_ctx field. I see no rationale for adding that though, as that
field does not seem to be managed via RCU at all.

If you have an NFSv4 mounted directory which does not container 'foo'
and:
ls -l foo
ssh $server touch foo
cat foo
then the 'cat' will fail (usually, depending a bit on the various
cache ages). This is correct as negative looks are cached by default.
However with the same initial conditions:
cat foo
ssh $server touch foo
cat foo
will usually succeed. This is because an "open" does not add a
negative dentry to the dcache, while a "lookup" does.
This can have negative performance effects. When "gcc" searches for
an include file, it will try to "open" the file in every director in
the search path. Without caching of negative "open" results, this
generates much more traffic to the server than it should (or than
NFSv3 does).
The root of the problem is that _nfs4_open_and_get_state() will call
d_add_unique() on a positive result, but not on a negative result.
Compare with nfs_lookup() which calls d_materialise_unique on both
a positive result and on ENOENT.
This patch adds a call d_add() in the ENOENT case for
_nfs4_open_and_get_state() and also calls nfs_set_verifier().
With it, many fewer "open" requests for known-non-existent files are
sent to the server.

There was a check for result being not NULL. But get_acl() may return
NULL, or ERR_PTR, or actual pointer.
The purpose of the function where current change is done is to "list
ACLs only when they are available", so any error condition of get_acl()
mustn't be elevated, and returning 0 there is still valid.

This patch is to fix following error while compiling OF selftests.
"drivers/of/selftest.c:617:2: error: implicit declaration of function
'of_fdt_unflatten_tree'"
Now, CONFIG_OF_SELFTEST depends on CONFIG_OF_EARLY_FLATTREE so that the
broken configuration cannot be selected. Ultimately it would be a good
idea to allow CONFIG_OF_SELFTEST to select CONFIG_OF_EARLY_FLATTREE, but
there is a dependency problem on i386 and x86_64 that causes dtc to not
get built and causes the build to fail. That problem needs to be fixed
first.

The offset of register DSIM_PLLTMR_REG in Exynos5410 / 5420 / 5440
SoCs is different from the one in Exynos4 SoCs.
In case of Exynos5410 / 5420 / 5440 SoCs, there is no frequency
band bit in DSIM_PLLCTRL_REG, and it uses DSIM_PHYCTRL_REG and
DSIM_PHYTIMING*_REG instead.
So this patch adds driver data to distinguish it.

To support MIPI command mode based I80 interface panel,
FIMD should do followings:
- Sets LCD I80 interface timings configuration.
- Uses "lcd_sys" as an IRQ resource and sets relevant IRQ configuration.
- Sets LCD block configuration for I80 interface.
- Sets ideal(pixel) clock is 2 times faster than the original one
to generate frame done IRQ prior to the next TE signal.
- Implements trigger feature that transfers image data if there is page
flip request, and implements TE handler to call trigger function.

This is a temporary solution and should be made by more
generic way.
To support LCD I80 interface, the DSI host should register
TE interrupt handler from the TE GPIO of attached panel.
So the panel generates a tearing effect synchronization signal
then the DSI host calls the CRTC device manager to trigger
to transfer video image.

To support LCD I80 interface, the panel should generate
Tearing Effect synchronization signal between MCU and FB
to display video images.
And the display controller should trigger to transfer
video image at this signal.
So the panel receives the TE IRQ, then calls these handler
chains to notify it to the display controller.

with some abnormal condition such as panel reset. So this patch replaces

HDMI_EN regulator is additional regulator for providing voltage source

provided for DDC epprom, some TV-sets do not pulls up HPD (hot plug

Fix a NULL pointer exception when main exynos drm driver was probed
successfully but no components were added (e.g. by incomplete DTS). In
such case the exynos_drm_load() is never called and drvdata is NULL.
The NULL pointer exception may theoretically also happen as a effect of race between
adding components and main driver: if suspend of the driver happens
before adding components.

Add missing Makefile rule for r8152 driver
In the current kernel the r8152 driver is *never* built because of a missing rule in drivers/net/Makefile, despite being selected as built-in or module in the .config file. There is no error message or warning to indicate that the driver isn't built. This change adds the rule and lets the driver build.
Tested as built-in and module for 3.15.8.
