Changeset 11502:d3ab28442a8e --------------------------- arm: Rewrite ERET to behave according to the ARMv8 ARM The ERET instruction doesn't set PSTATE correctly in some cases (particularly when returning to aarch32 code). Among other things, this breaks EL0 thumb code when using a 64-bit kernel. This changeset updates the ERET implementation to match the ARM ARM.
