Denys Vlasenko aa6d9a128b x86/irq/tracing: Do not save callee-preserved registers around lockdep_sys_exit_thunk ... Internally, lockdep_sys_exit_thunk saves callee-clobbered registers, and calls a C function, lockdep_sys_exit. Thus, callee-preserved registers won't be mangled, there is no need to save them. Patch was run-tested.
