Greg Kroah-Hartman 1b86960dc4 Revert "x86: Fix get_wchan() to support the ORC unwinder" 
This reverts commit f270511247 which is
commit bc9bbb8173 upstream.

It has been reported to be causing problems, and is being reworked
upstream and has been dropped from the current 5.15.y stable queue until
it gets resolved.
