Fix MODULE_PARM_DESC() strings in several watchdog drivers.
Some are simple as add a parenthesis.
Others are problems from __stringify() being used on a
variable name instead of a macro name, so the variable name
is produced in the string instead of its build-time value.
In these cases, create a macro for the value so that the
module param description string is useful.
Only pc87413_wdt has been built (due to toolchains).

exofs: confusion between kmap() and kmap_atomic() api

This reverts commit 03ceedea97, since it
breaks resume from suspend-to-ram on Rafael's Acer Ferrari One.
NetworkManager thinks everything is ok, but it can't connect to the AP
to get an IP address after the resume.
In fact, it even breaks resume for non-ath9k chipsets: reverting it also
fixes Rafael's Toshiba Protege R500 with the iwlagn driver. As Johannes
says:
"Indeed, this patch needs to be reverted. That mac80211 change is wrong
and completely unnecessary."

commit 64ce4c2f (time: Clean up warp_clock()) breaks the timezone
update in a very subtle way. To avoid the direct access to timekeeping
internals it adds the timezone delta to the current time with
timespec_add_safe(). This works nicely when the timezone delta is > 0.
If timezone delta is < 0 then the wrap check in timespec_add_safe()
triggers and timespec_add_safe() returns TIME_MAX and screws up
timekeeping completely.
The comment above timespec_add_safe() says:
It's assumed that both values are valid (>= 0)
Add the timezone seconds adjustment directly.

Add a little strncpy optimization which can easily cut boot time by 20%.
When the kernel is booting with initramfs, it builds up the filesystem
from a cpio archive by calling strncpy_from_user() via fs/namei.c's
do_getname() on every file in the archive (which can be lots) with a
length of PATH_MAX (1024). This causes the dest of the strncpy to be
padded with many NUL bytes.
This optimization mostly causes these NUL bytes to be padded with a call
to memset() which is already optimized for filling memory quickly, but
the hardware loop helps a little bit as well.
Boot time measured with 'loglevel=0' so UART speed doesn't get in the way.

Since 'extern inline' doesn't work correctly in the context of the Linux
kernel (too many overriding defines), move the string functions to normal
lib/ assembly files (like the existing mem funcs). This avoids the forced
inline all over the kernel and allows us to place them constantly in L1.
This also avoids some module failures when gcc inserts calls to string
functions but the kernel build system doesn't fully consult the library
archives.

NMIs are not safe to return from because many anomaly workarounds are
implemented by disabling interrupts. The NMI obviously violates this
assumption. Since the NMI watchdog never returns, we don't have to

with the exception stack.

A few pseudo debug insns exist to make testing of simulators easier.
Since these don't actually exist in the hardware, we have to have the
