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"
