Merge tag 'for-linus' of git://github.com/rustyrussell/linux
Autogenerated GPG tag for Rusty D1ADB8F1: 15EE 8D6C AB0E 7F0C F999 BFCB D920 0E6C D1AD B8F1 * tag 'for-linus' of git://github.com/rustyrussell/linux: module_param: check that bool parameters really are bool. intelfbdrv.c: bailearly is an int module_param paride/pcd: fix bool verbose module parameter. module_param: make bool parameters really bool (drivers & misc) module_param: make bool parameters really bool (arch) module_param: make bool parameters really bool (core code) kernel/async: remove redundant declaration. printk: fix unnecessary module_param_name. lirc_parallel: fix module parameter description. module_param: avoid bool abuse, add bint for special cases. module_param: check type correctness for module_param_array modpost: use linker section to generate table. modpost: use a table rather than a giant if/else statement. modules: sysfs - export: taint, coresize, initsize kernel/params: replace DEBUGP with pr_debug module: replace DEBUGP with pr_debug module: struct module_ref should contains long fields module: Fix performance regression on modules with large symbol tables module: Add comments describing how the "strmap" logic works Fix up conflicts in scripts/mod/file2alias.c due to the new linker- generated table approach to adding __mod_*_device_table entries. The ARM sa11x0 mcp bus needed to be converted to that too.
