The fix is really the last patch, 923510c88d2b ("x86/static_call: Add support
for Jcc tail-calls"). I see that 6.1 got 3,4,5:
9d80f3e60043 x86/static_call: Add support for Jcc tail-calls
c51a456b4179 x86/alternatives: Teach text_poke_bp() to patch Jcc.d32 instructions
75c066485bcb x86/alternatives: Introduce int3_emulate_jcc()
I can resubmit the series without the first two patches if that is preferred.
Thanks.
Cascardo.
