Hi,

you have in Linux 5.10.13-rc1:

"x86/entry: Emit a symbol for register restoring thunk"

While that discussion Boris and Peter recommended to remove unused code via:

"x86/entry: Remove put_ret_addr_in_rdi THUNK macro argument" ( upstream commit 0bab9cb2d980d7c075cffb9216155f7835237f98 )

OK, this has no CC:stable but I have both as a series in my local Git and both were git-pulled from [1]. What do you think?

What bug is this fixing that requires this in 5.10?

thanks,
