libacpi: report PCI slots as enabled only for hotpluggable devices DSDT for qemu-xen lacks _STA method of PCI slot object. If _STA method doesn't exist then the slot is assumed to be always present and active which in conjunction with _EJ0 method makes every device ejectable for an OS even if it's not the case. qemu-kvm is able to dynamically add _EJ0 method only to those slots that either have hotpluggable devices or free for PCI passthrough. As Xen lacks this capability we cannot use their way. qemu-xen-traditional DSDT has _STA method which only reports that the slot is present if there is a PCI devices hotplugged there. This is done through querying of its PCI hotplug controller. qemu-xen has similar capability that reports if device is "hotpluggable or absent" which we can use to achieve the same result.

When assigning a cpu to a cpupool with credit2 being the default scheduler csched2_deinit_pdata() is called for the credit2 private data after the new scheduler's private data has been hooked to the per-cpu scheduler data. Unfortunately csched2_deinit_pdata() will cycle through all per-cpu scheduler areas it knows of for removing the cpu from the respective sibling masks including the area of the just moved cpu. This will (depending on the new scheduler) either clobber the data of the new scheduler or in case of sched_rt lead to a crash. Avoid that by removing the cpu from the list of active cpus in credit2 data first. The opposite problem is occurring when removing a cpu from a cpupool: init_pdata() of credit2 will access the per-cpu data of the old scheduler.

This is particulary important since the function doesn't bail early when tracing is not active, so even production builds would be affected by potential misbehavior here. Take the opportunity and also - use initializers instead of assignment + memset(), - constify the cpumask_t input pointer, - u32 -> uint32_t.

To retain the slimming effect of compiling out CONFIG_VIDEO, adjust cmdline.c with enough #ifdef-ary to make C's idea of the structure match the declaration in asm.

Introduce a BUILD_BUG_ON() as replacement, for the unlikely case that Xen might get ported to an architecture where array alignment higher that that of its elements.
