*	x86/S3: add cache flush on secondary CPUs before going to sleep	Ben Guthro	2012-09-25	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Secondary CPUs, between doing their final memory writes (particularly updating cpu_initialized) and getting a subsequent INIT, may not write back all modified data. The INIT itself then causes those modifications to be lost, so in the cpu_initialized case the CPU would find itself already initialized, (intentionally) entering an infinite loop instead of actually coming online. Signed-off-by: Ben Guthro <ben@guthro.net> Make acpi_dead_idle() call default_dead_idle() rather than duplicating the logic there.

*	x86: fix MWAIT-based idle driver for CPUs without ARAT	Jan Beulich	2012-09-25	1	-0/+1
\| \| \| \| \| \| \| \|	lapic_timer_{on,off} need to get initialized in this case. This in turn requires getting HPET broadcast setup to be carried out earlier (and hence preventing double initialization there). Signed-off-by: Jan Beulich <jbeulich@suse.com>
*	x86: introduce MWAIT-based, ACPI-less CPU idle driver	Jan Beulich	2012-09-21	1	-0/+35
	This is a port of Linux'es intel-idle driver serving the same purpose. Signed-off-by: Jan Beulich <jbeulich@suse.com> Acked-by: Keir Fraser <keir@xen.org>
