Merge tag 'modules-for-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull modules updates from Jessica Yu: "Summary of modules changes for the 4.10 merge window: - The rodata= cmdline parameter has been extended to additionally apply to module mappings - Fix a hard to hit race between module loader error/clean up handling and ftrace registration - Some code cleanups, notably panic.c and modules code use a unified taint_flags table now. This is much cleaner than duplicating the taint flag code in modules.c" * tag 'modules-for-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux: module: fix DEBUG_SET_MODULE_RONX typo module: extend 'rodata=off' boot cmdline parameter to module mappings module: Fix a comment above strong_try_module_get() module: When modifying a module's text ignore modules which are going away too module: Ensure a module's state is set accordingly during module coming cleanup code module: remove trailing whitespace taint/module: Clean up global and module taint flags handling modpost: free allocated memory
