Even after a "make mrproper" and "git clean -fxd" I'm seeing lots of
warnings and errors.

can't find jump dest instruction
stack state mismatch
return with modified stack frame
objtool: can't decode instruction
can't find starting instruction

gcc (Gentoo Hardened 14.3.0 p8) 14.3.0

I selected "Y" to the new config option "X86_NATIVE_CPU"

CPU is AMD FX-8350

.config attached

The build is fine on a cross-compile of a minimal kernel for an Intel
Atom server.
