Revision 883bbbffa5a4ffd1915f8b42934dab81b7f87226 authored by Peter Zijlstra on 18 October 2022, 11:49:21 UTC, committed by Peter Zijlstra on 20 October 2022, 15:10:27 UTC
Different function signatures means they needs to be different
functions; otherwise CFI gets upset.
As triggered by the ftrace boot tests:
[] CFI failure at ftrace_return_to_handler+0xac/0x16c (target: ftrace_stub+0x0/0x14; expected type: 0x0a5d5347)
Fixes: 3c516f89e17e ("x86: Add support for CONFIG_CFI_CLANG")
