Subject: [PATCH] MIPS: KVM: Use __local_flush_icache_user_range()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Convert KVM dynamic translation of guest instructions to flush icache
for guest mapped addresses using the new
__local_flush_icache_user_range() API to allow the more generic
flush_icache_range() to be changed to work on kernel addresses only.
