AFAICS this is safe: the lock is only used in the .ndo_start_xmit

When using `make localmodconfig` and friends, if the input config comes
from a kernel that was built in a different environment (for example, the
canonical case of using localmodconfig to trim a distribution kernel
config) the key files for module signature checking will not be available
and should be regenerated or omitted. Otherwise, the user will be faced
with annoying errors when trying to build with the generated .config:

only subject to the execmem permission check. Augment

Note that this does NOT prevent making a different thread's

Distinguish capability checks against a target associated
with the init user namespace versus capability checks against
a target associated with a non-init user namespace by defining
and using separate security classes for the latter.
This is needed to support e.g. Chrome usage of user namespaces
for the Chrome sandbox without needing to allow Chrome to also

This reverts commit 320d25b6a0.
This change was problematic for a couple of reasons:
1. It missed a some entry points (Xen things and 64-bit native).
2. The entry it changed can be executed more than once. This isn't
really a problem, but it conflated per-cpu state setup and global
state setup.
3. It broke 64-bit non-NX. 64-bit non-NX worked the other way around from
32-bit -- __supported_pte_mask had NX set initially and was *cleared*
in x86_configure_nx. With the patch applied, it never got cleared.

DRA7 family of processors from Texas Instruments, have a hardware module
called IODELAYCONFIG Module which is expected to be configured. This
block allows very specific custom fine tuning for electrical
characteristics of IO pins that are necessary for functionality and
device lifetime requirements. IODelay module has it's own register space
with registers to configure various pins.
According to AM572x TRM SPRUHZ6E October 2014–Revised January 2016[1]
section 18.4.6.1 Pad Configuration, in addition to pinmuxing(MUXMODE),
when operating a pad in certain mode, Virtual/Manual IO Timing Mode must
also be configured to ensure that IO timings are met (DELAYMODE and
MODESELECT fields of pad's IODELAYCONFIG module register). According to
section 18.4.6.1.7 Isolation Requirements of above TRM, when
reprogramming MUXMODE, DELAYMODE, and MODESELECT fields, there is a
potential for a significant glitch on the corresponding IO. It is hence
recommended to do this with I/O isolation (which can only be done in
initial stages of bootloader). QSPI is one such module that requires
IODELAY configuration. So, this patch removes the pinmux for
QSPI for DRA74/DRA72 EVM as it needs to be done in bootloader (U-Boot)
and cannot be done in kernel.
Users should migrate to U-Boot v2016.05-rc1 or higher.

The firmware can send a set of asynchronous replies through FW_PORT_CMD
with DCBX information when that's negotiated with the Link Peer. The old
code always assumed that a FW_PORT_CMD reply was always a Get Port
Information message. This change conditionalizes the code to only handle
the Get Port Information messages and throws a warning if we don't
understand what we've been given.
