Subject: Re: [PATCH] s390: Use static call trampolines when kCFI is enabled

> Add support for the 'unoptimized' static call variety, which routes all
> calls through a trampoline that performs a tail call to the chosen
> function. Wire it up for use when kCFI is enabled to work around an
> issue where the prototypes of default handlers such as
> __static_call_nop() and __static_call_ret0() don't match the expected
> prototype of the call site, resulting in kCFI false positives.
