      [MIPS] c-r4k: Convert init functions from inline to __init. · a00f6310
      Ralf Baechle authored
      
      
      With more recent compilers inline doesn't necessarily means a function
      will always be inlined.  So leave that decission to the compiler and
      make the function as __init.

      [MIPS] Do not use drop_mmu_context to flusing other task's VIPT I-cache. · f6502791
      Atsushi Nemoto authored
      
      
      c-r4k.c and c-sb1.c use drop_mmu_context() to flush virtually tagged
      I-caches, but this does not work for flushing other task's icache.  This
      is for example triggered by copy_to_user_page() called from ptrace(2).
      Use indexed flush for such cases.

      [MIPS] Retire flush_icache_page from mm use. · 585fa724
      Ralf Baechle authored
      
      
      On the 34K the redundant cache operations were causing excessive stalls
      resulting in realtime code running on the second VPE missing its deadline.
      For all other platforms this patch is just a significant performance
      improvment as illustrated by below benchmark numbers.
