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

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.
