Merge branch 'params' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus
* 'params' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus: (22 commits) param: don't deref arg in __same_type() checks param: update drivers/acpi/debug.c to new scheme param: use module_param in drivers/message/fusion/mptbase.c ide: use module_param_named rather than module_param_call param: update drivers/char/ipmi/ipmi_watchdog.c to new scheme param: lock if_sdio's lbs_helper_name and lbs_fw_name against sysfs changes. param: lock myri10ge_fw_name against sysfs changes. param: simple locking for sysfs-writable charp parameters param: remove unnecessary writable charp param: add kerneldoc to moduleparam.h param: locking for kernel parameters param: make param sections const. param: use free hook for charp (fix leak of charp parameters) param: add a free hook to kernel_param_ops. param: silence .init.text references from param ops Add param ops struct for hvc_iucv driver. nfs: update for module_param_named API change AppArmor: update for module_param_named API change param: use ops in struct kernel_param, rather than get and set fns directly param: move the EXPORT_SYMBOL to after the definitions. ...
