[patch 0/4] A series of cleanup patches

[Jeremy Fitzhardinge <jeremy@goop.org>]

Hi Andi, Andrew,

Here's a series of cleanup patches:

1. add kstrndup, which is needed by
2. add argv_split, a helper for splitting a string into an argv array,
3. a restructuring of the call_usermodehelper set of functions, to make
   them more flexible, needed by
4. a common orderly_poweroff() function, which replaces various ad-hoc
   ways of powering off the machine used around the kernel

Thanks,
	J
