Max Filippov 713f903dc4 xtensa: disable preemption around cache alias management calls ... commit 3a860d165e upstream. Although cache alias management calls set up and tear down TLB entries and fast_second_level_miss is able to restore TLB entry should it be evicted they absolutely cannot preempt each other because they use the same TLBTEMP area for different purposes. Disable preemption around all cache alias management calls to enforce that.
