*	cputime: Bring cputime -> nsecs conversion	Frederic Weisbecker	2014-03-13	1	-0/+5
\| \| \| \| \| \| \| \| \| \| \| \|	We already have nsecs_to_cputime(). Now we need to be able to convert the other way around in order to fix a bug on steal time accounting.

*	cputime: Default implementation of nsecs -> cputime conversion	Frederic Weisbecker	2014-03-13	1	-0/+11
	The architectures that override cputime_t (s390, ppc) don't provide any version of nsecs_to_cputime(). Indeed this cputime_t implementation by backend only happens when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y under which the core code doesn't make any use of nsecs_to_cputime(). At least for now. We are going to make a broader use of it so lets provide a default version with a per usecs granularity. It should be good enough for most usecases.
