Atsushi Nemoto f6502791d7 [MIPS] Do not use drop_mmu_context to flusing other task's VIPT I-cache.
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.
