arm64: efi: Revert "Recover from synchronous exceptions ..." This reverts commit 23715a26c8d81291, which introduced some code in assembler that manipulates both the ordinary and the shadow call stack pointer in a way that could potentially be taken advantage of. So let's revert it, and do a better job the next time around. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
