Peter Zijlstra	0cd7c741f0	delayacct: Add sysctl to enable at runtime ... Just like sched_schedstats, allow runtime enabling (and disabling) of delayacct. This is useful if one forgot to add the delayacct boot time option.

Peter Zijlstra	e4042ad492	delayacct: Default disabled ... Assuming this stuff isn't actually used much; disable it by default and avoid allocating and tracking the task_delay_info structure. taskstats is changed to still report the regular sched and sched_info and only skip the missing task_delay_info fields instead of not reporting anything.

Mauro Carvalho Chehab	c3123552aa	docs: accounting: convert to ReST ... Rename the accounting documentation files to ReST, add an index for them and adjust in order to produce a nice html output via the Sphinx build system. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
