Patch 1/3 is a livepatch bug fix for a crash which occurs when loading a patch module on a kernel without CONFIG_DEBUG_SET_MODULE_RONX.
Patch 2/3 is a module code cleanup to make setting and clearing RO and NX more symmetrical. It also adds some new functions which are used by patch 3.
Patch 3/3 is a livepatch cleanup for simplification of the livepatch relocation code.
v2: - removed set_page_attributes() duplication in livepatch cleanup patch in favor of using new {un}set_module_core_ro_nx() functions - changed 'size' from int to size_t
Josh Poimboeuf (3): livepatch: Fix crash with !CONFIG_DEBUG_SET_MODULE_RONX module: Use the same logic for setting and unsetting RO/NX livepatch: Cleanup module page permission changes
