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
