[PATCH] objtool, module: discard __unreachable section for modules

Show all headers | View raw

The __unreachable section is only used at compile time.  It's discarded
for vmlinux but it should also be discarded for modules.

Fixes: d1091c7fa3d5 ("objtool: Improve detection of BUG() and other dead ends")
