Subject: create-diff-object: Add is_special_section() helper function
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=ef3437d3c300ededc6f66f13d08d1083109b6f58;p=people%2Fwipawel%2Flivepatch-build-tools

create-diff-object: Add is_special_section() helper function

This function determines, based on the given section name, if the
sections belongs to the special sections category.

Add more special sections to special_sections[] along with a new
undefined_group_size() helper function returning 0 (undefined).
New special sections are: .altinstr_replacement.
