xtensa: add missing isync to the cpu_reset TLB code
commit cd8869f4 upstream. ITLB entry modifications must be followed by the isync instruction before the new entries are possibly used. cpu_reset lacks one isync between ITLB way 6 initialization and jump to the identity mapping. Add missing isync to xtensa cpu_reset. Cc: stable@vger.kernel.org Signed-off-by:Max Filippov <jcmvbkbc@gmail.com> Signed-off-by:
