[PATCH 11/35] [PATCH 11/36] watchdog: Replace __raw_get_cpu_var uses

[Christoph Lameter <cl@linux.com>]

[-- Attachment #1: 0011-watchdog-Replace-__raw_get_cpu_var-uses.patch --]
[-- Type: text/plain, Size: 2105 bytes --]

Most of these are the uses of &__raw_get_cpu_var for address calculation.

touch_softlockup_watchdog_sync() uses __raw_get_cpu_var to write to
per cpu variables. Use __this_cpu_write instead.
