[PATCH 0/7] livepatch-build-tools: fixes for handling .cold and .hot sections

Posted by Roger Pau Monne 2 weeks, 5 days ago

Hello,

Fixes picked from kpatch to deal with .cold and .hot sub-functions
sections generated by gcc.

Thanks, Roger.

Artem Savkov (7):
  create-diff-object: ignore .cold.* suffixes in is_bundleable()
  create-diff-object: add symbol relations
  create-diff-object: propagate child symbol changes
  create-diff-object: allow changing subsections
  create-diff-object: add .text.hot to the list of bundleable functions
  create-diff-object: propagate ignore.functions to children
  create-build-diff: support for .cold functions with no id suffix

 common.c             |  9 ++++-
 common.h             |  2 ++
 create-diff-object.c | 78 +++++++++++++++++++++++++++++++++++++++++---
