Subject: [PATCH 0/3] MIPS: Enable ARCH_SUPPORTS_ATOMIC_RMW 

Hi all,

This series enables ARCH_SUPPORTS_ATOMIC_RMW for MIPS.
The first two patches are for making LLSC availability information
available to Kconfig, and the last one selects the actual option.

Please review.

Thanks
- Jiaxun

  MIPS: Introduce WAR_4KC_LLSC config option
  MIPS: Introduce config options for LLSC availability
  MIPS: Select ARCH_SUPPORTS_ATOMIC_RMW when possible
