The series cleans up ARCH_HAS_DECOMP_WDOG and arch_decomp_wdog which

are unused on ARM architecure.  Samsung has some code setting up wdog
 in arch_decomp_wdog().  But since CONFIG_S3C_BOOT_WATCHDOG is defined
 nowhere, it will not run.  Otherwise, system can not boot at all when
 wdog is set up but no one pats it.

Merge tag 'cleanup-decompwdog-3.9' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/cleanup

From Shawn Guo:
The series cleans up ARCH_HAS_DECOMP_WDOG and arch_decomp_wdog which
are unused on ARM architecure.  Samsung has some code setting up wdog
in arch_decomp_wdog().  But since CONFIG_S3C_BOOT_WATCHDOG is defined
nowhere, it will not run.  Otherwise, system can not boot at all when
wdog is set up but no one pats it.

* tag 'cleanup-decompwdog-3.9' of git://git.linaro.org/people/shawnguo/linux-2.6:
  ARM: samsung: remove unused arch_decomp_wdog() code
  ARM: remove unused arch_decomp_wdog()
  ARM: decompress: remove unused ARCH_HAS_DECOMP_WDOG
