H A D | callthunks.c | 02012623 Tue May 16 08:56:46 CDT 2023 Josh Poimboeuf <jpoimboe@kernel.org> Revert "x86/orc: Make it callthunk aware"
Commit 396e0b8e09e8 ("x86/orc: Make it callthunk aware") attempted to deal with the fact that function prefix code didn't have ORC coverage. However, it didn't work as advertised. Use of the "null" ORC entry just caused affected unwinds to end early.
The root cause has now been fixed with commit 5743654f5e2e ("objtool: Generate ORC data for __pfx code").
Revert most of commit 396e0b8e09e8 ("x86/orc: Make it callthunk aware"). The is_callthunk() function remains as it's now used by other code.
