Merge tag 'stable/for-linus-3.11-rc0-tag-two' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen bugfixes from Konrad Rzeszutek Wilk: - Fix memory leak when CPU hotplugging. - Compile bugs with various #ifdefs - Fix state changes in Xen PCI front not dealing well with new toolstack. - Cleanups in code (use pr_*, fix 80 characters splits, etc) - Long standing bug in double-reporting the steal time * tag 'stable/for-linus-3.11-rc0-tag-two' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/time: remove blocked time accounting from xen "clockchip" xen: Convert printks to pr_<level> xen: ifdef CONFIG_HIBERNATE_CALLBACKS xen_*_suspend xen/pcifront: Deal with toolstack missing 'XenbusStateClosing' state. xen/time: Free onlined per-cpu data structure if we want to online it again. xen/time: Check that the per_cpu data structure has data before freeing. xen/time: Don't leak interrupt name when offlining. xen/time: Encapsulate the struct clock_event_device in another structure. xen/spinlock: Don't leak interrupt name when offlining. xen/smp: Don't leak interrupt name when offlining. xen/smp: Set the per-cpu IRQ number to a valid default. xen/smp: Introduce a common structure to contain the IRQ name and interrupt line. xen/smp: Coalesce the free_irq calls in one function. xen-pciback: fix error return code in pcistub_irq_handler_switch()
