-Subject: MIPS: unaligned: Fix regular load/store instruction emulation for EVA
-
-From: Markos Chandras <markos.chandras@imgtec.com>
-
-commit 6eae35485b26f9e51ab896eb8a936bed9908fdf6 upstream.
-
-When emulating a regular lh/lw/lhu/sh/sw we need to use the appropriate
-instruction if we are in EVA mode. This is necessary for userspace
-applications which trigger alignment exceptions. In such case, the
-userspace load/store instruction needs to be emulated with the correct
-eva/non-eva instruction by the kernel emulator.
