* 'upstream/for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen: (23 commits) xen/events: Use PIRQ instead of GSI value when unmapping MSI/MSI-X irqs. xen: set IO permission early (before early_cpu_init()) xen: re-enable boot-time ballooning xen/balloon: make sure we only include remaining extra ram xen/balloon: the balloon_lock is useless xen: add extra pages to balloon xen: make evtchn's name less generic xen/evtchn: the evtchn device is non-seekable Revert "xen/privcmd: create address space to allow writable mmaps" xen/events: use locked set|clear_bit() for cpu_evtchn_mask xen/evtchn: clear secondary CPUs' cpu_evtchn_mask[] after restore xen/xenfs: update xenfs_mount for new prototype xen: fix header export to userspace xen: implement XENMEM_machphys_mapping xen: set vma flag VM_PFNMAP in the privcmd mmap file_op xen: xenfs: privcmd: check put_user() return code xen/evtchn: add missing static xen/evtchn: Fix name of Xen event-channel device xen/evtchn: don't do unbind_from_irqhandler under spinlock xen/evtchn: remove spurious barrier ...
