Revision ad2daa85bd50b7ff5c851b80a0b813bdc8d14f8e authored by Mark Rutland on 10 July 2015, 14:46:32 UTC, committed by Catalin Marinas on 10 July 2015, 15:47:13 UTC
We currently set x27 in compat_sys_sigreturn_wrapper and compat_sys_rt_sigreturn_wrapper, similarly to what we do with r8/why on 32-bit ARM, in an attempt to prevent sigreturns from being restarted. However, on arm64 we have always used pt_regs::syscallno for syscall restarting (for both native and compat tasks), and x27 is never inspected again before being overwritten in kernel_exit. This patch removes the pointless register assignments.
