Merge tag 'stable/for-linus-3.12-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull Xen fixes from Konrad Rzeszutek Wilk: "Bug-fixes and one update to the kernel-paramters.txt documentation. - Fix PV spinlocks triggering jump_label code bug - Remove extraneous code in the tpm front driver - Fix ballooning out of pages when non-preemptible - Fix deadlock when using a 32-bit initial domain with large amount of memory - Add xen_nopvpsin parameter to the documentation" * tag 'stable/for-linus-3.12-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/spinlock: Document the xen_nopvspin parameter. xen/p2m: check MFN is in range before using the m2p table xen/balloon: don't alloc page while non-preemptible xen: Do not enable spinlocks before jump_label_init() has executed tpm: xen-tpmfront: Remove the locality sysfs attribute tpm: xen-tpmfront: Fix default durations
