Per cpu variable softnet_data.total was shared between IRQ and SoftIRQ context
without any protection. And enqueue_to_backlog should update the netdev_rx_stat
of the target CPU.
This patch renames softnet_data.total to softnet_data.processed: the number of
packets processed in uppper levels(IP stacks).
softnet_stat data is moved into softnet_data.

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.

The driver isn't buildable since 2.6.32 (i.e. commit b4028437
"Driver core: move dev_get/set_drvdata to drivers/base/dd.c"):
CC tosa_battery.o
tosa_battery.c: In function 'tosa_read_bat':
tosa_battery.c:64: error: 'struct device' has no member named 'driver_data'
tosa_battery.c: In function 'tosa_read_temp':

Nowadays we must not access driver_data directly, use dev_get_drvdata()
instead.

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.
