Max Filippov 244066f4be xtensa: fix fast_syscall_spill_registers_fixup ... fast_syscall_spill_registers_fixup was not correctly updated by the 'keep a3 and excsave1 on entry to exception handlers' patch: it doesn't preserve a3 that it gets on entry, breaking _spill_registers in case of page fault on stack during register spilling, leading to unhandled exception in kernel mode. Preserve a3 by saving it in the original _spill_registers stack frame's a3 during exception handling and restoring it afterwards. Also fix comments and function bounds annotations.
