* 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.
