SUNRPC: Prevent kernel stack corruption on long values of flush
NLM: nlm_lookup_file() may return NLMv4-specific error codes
ehci_fsl_setup_phy is supposed to return an int, but had a void return

Temperature scale and offset differ between the different devices supported by
this driver. Right now the driver always reports the temperature scale and
offset of the adis16400 regardless of which chip variant is used. This patch
adds two new attributes to the chip_info struct, one for the temperature scale
and one for the temperature offset.

Most of the channel offsets and scales in the adis16400 are incorrect:
* Voltage scale is off by a factor of 1000
* Temperature scale is off by a factor of 1000
* Temperature offset is completely wrong
* Some of the acceleration scales are either completely wrong or have the
wrong unit
* Some of the angular velocity scale are either completely wrong or have
the wrong unit
This patch fixes these issues. For consistency it also converts scales which are
correct to use the IIO_G_TO_M_S_2 and IIO_DEGREE_TO_RAD macro. This makes it
much easier to compare it to the value given in the datasheet.

Some datasheets use a different unit to specify the channel scale than what IIO
expects it to be. This patch adds two helper macros which allow to convert units
commonly used in datasheets to IIO units:
* acceleration: g -> meter / second**2
* angular velocity: degree (/ second) -> rad (/ second)
This makes it much more convenient to specify and also easier to verify a
channel's scale attribute.

From Borislav Petkov <bp@amd64.org>:
Below is a RAS fix which reverts the addition of a sysfs attribute
which we agreed is not needed, post-factum. And this should go in now
because that sysfs attribute is going to end up in 3.7 otherwise and
thus exposed to userspace; removing it then would be a lot harder.
This is done as a merge rather than a simple patch/cherry-pick since
the baseline for this patch was not in the previous x86/urgent.
Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
450cc20103 ("x86/mce: Provide boot argument to honour bios-set CMCI
threshold") added the bios_cmci_threshold sysfs attribute which was
supposed to communicate to userspace tools that BIOS CMCI threshold has
been honoured.
However, this info is not of any importance to userspace - it should
rather get the actual error count it has been thresholded already from
MCi_STATUS[38:52].
So drop this before it becomes a used interface (good thing we caught
this early in 3.7-rc1, right after the merge window closed).

Pull media fixes from Mauro Carvalho Chehab:
"Media fixes for:
- one Kconfig fix patch;
- one patch fixing DocBook breakage due to the drivers/media UAPI
changes;
- the remaining UAPI media changes (DVB API).
I'm aware that is is a little late for the UAPI renames for the DVB
API, but IMHO, it is better to merge it for 3.7, due to two reasons:
1) There is a major rename at 3.7 (not only uapi changes, but also
the entire media drivers were reorganized on 3.7, in order to
simplify the Kconfig logic, and easy drivers selection, especially
for hybrid devices). By confining all those renames there at 3.7
it will cause all the harm at for media developers on just one
shot. Stable backports upstream and at distros will likely
welcome it as well, as they won't need to check what changed on
3.7 and what was postponed for on 3.8.
2) The V4L2 DocBook Makefile creates a cross-reference between the
media API headers and the specs. This helps us _a_lot_ to be sure
that all API improvements are properly documented. Every time a
header changes from one place to another, DocBook/media/Makefile
needs to be patched. Currently, the DocBook breakage patch
depends on the DVB UAPI."

Commit 38f3865744 ("xattr: extract simple_xattr code from tmpfs") moved
some code from tmpfs but introduced a subtle bug along the way.
If the name passed to simple_xattr_remove() does not exist in the list of
xattrs, then it is possible to call kfree(new_xattr) when new_xattr is
actually initialized to itself on the stack via uninitialized_var().
This causes a BUG() since the memory was not allocated via the slab
allocator and was not bypassed through to the page allocator because it
was too large.
Initialize the local variable to NULL so the kfree() never takes place.

in order to sanity-check against the requested regset type. This will
fail because the encoding will appear as a zero-length breakpoint.

For historical reasons, ARM used to set r0-r2 in start_thread() to the
first values on the user stack when starting a new user application. The
same logic has been inherited in AArch64. The x0 register is overridden
by the sys_execve() return value so it's always zero on success. The x1
and x2 registers are ignored by AArch64 and EABI AArch32 applications,
so we can safely remove the register setting for both native and compat
user space.
This also fixes a potential fault with the kernel accessing user space
stack directly.
