We don't check "frontend" consistently in crypto_init_spawn2(). We
check it at the start of the function but then we dereference it
unconditionally in the parameter list when we call crypto_init_spawn().
I looked at the places that call crypto_init_spawn2() and "frontend" is
always a valid pointer so I removed the check for null.

Disable the processor clock when the CPU is idle.
This saves much more power than merely entering 'Wait for Interrupt' mode.
Since JTAG-debugging doesn't work when the processor clock is switched off,
make it conditional on CONFIG_DEBUG_KERNEL.

This patch fixes following sparse warning:
drivers/power/wm97xx_battery.c:311:6: warning: symbol 'wm97xx_bat_set_pdata' was not declared. Should it be static?
Note that we can't just include linux/wm97xx_batt.h because the header
is deprecated, and so this pops up:
In file included from drivers/power/wm97xx_battery.c:22:
include/linux/wm97xx_batt.h:6: warning: #warning This file will be removed soon, use wm97xx.h instead!
Since wm97xx_bat_set_pdata() is also deprecated (in favour of pdata
passed via AC97 bus), just workaround the issue by declaring the
function in wm97xx_battery.c.

Link Down -> Mark all devices missing
Previously, the driver took no action on a Link Down,
and waited for the I/O on a dead connection to timeout
in the firmware before marking the DDB missing.
Link Up -> Mark all devices online
F/W will do auto login to all the devices only once.
After that its the responsibility of the driver to
relogin to devices whenever there is :
* Any sort of connection failure or
* KATO expires indicating target has logged out or
* I/O times out etc.

Currently, perf 'live mode' writes build-ids at the end of the
session, which isn't actually useful for processing live mode events.
What would be better would be to have the build-ids sent before any of
the samples that reference them, which can be done by processing the
event stream and retrieving the build-ids on the first hit. Doing
that in perf-record itself, however, is off-limits.
This patch introduces perf-inject, which does the same job while
leaving perf-record untouched. Normal mode perf still records the
build-ids at the end of the session as it should, but for live mode,
perf-inject can be injected in between the record and report steps
e.g.:
perf record -o - ./hackbench 10 | perf inject -v -b | perf report -v -i -
perf-inject reads a perf-record event stream and repipes it to stdout.
At any point the processing code can inject other events into the
event stream - in this case build-ids (-b option) are read and
injected as needed into the event stream.
Build-ids are just the first user of perf-inject - potentially
anything that needs userspace processing to augment the trace stream
with additional information could make use of this facility.

[SCSI] libiscsi: don't increment cmdsn if cmd is not sent
in 2.6.32.
When I moved the hdr->cmdsn after init_task, I added
a bug when header digests are used. The problem is
that the LLD may calculate the header digest in init_task,
so if we then set the cmdsn after the init_task call we
change what the digest will be calculated by the target.
