Martin Stein 9da42dde2f hw & arm_v7: mode transition via transit ttbr0 ... Previously, we did the protection-domain switches without a transitional translation table that contains only global mappings. This was fine as long as the CPU did no speculative memory accesses. However, to enabling branch prediction triggers such accesses. Thus, if we don't want to invalidate predictors on every context switch, we need to switch more carefully. ref #474		2014-08-15 10:19:48 +02:00
