Subject: objtool: Skip ORC entry creation for non-text sections
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3eaecac88a17f7fdf29561a197dc728f7f697c60;p=linux.git

objtool: Skip ORC entry creation for non-text sections

Orc generation is only done for text sections, but some instructions
can be found in non-text sections (e.g. .discard.text sections).

Skip setting their orc sections since their whole sections will be
skipped for orc generation.
