Hauke Mehrtens 626bfa0372 MIPS: kernel: proc: add CPU option reporting 
Many MIPS CPUs have optional CPU features which are not activated for
all CPU cores. Print the CPU options, which are implemented in the core,
in /proc/cpuinfo. This makes it possible to see which features are
supported and which are not supported. This should cover all standard
MIPS extensions. Before, it only printed information about the main MIPS
ASEs.

Changes from original patch[0]:
- Remove cpu_has_6k_cache and cpu_has_8k_cache due to commit 6ce91ba858
  ("MIPS: Remove cpu_has_6k_cache and cpu_has_8k_cache in cpu_cache_init()")
- Add new options: mac2008_only, ftlbparex, gsexcex, mmid, mm_sysad,
  mm_full
- Use seq_puts instead of seq_printf as suggested by checkpatch
- Minor commit message reword
