[GIT PULL] KVM/ARM updates for 4.13

[Marc Zyngier <marc.zyngier@arm.com>]

Paolo, Radim,

This is the pull request for the 4.13 edition of KVM/ARM. Among the
changes this time around, a rework of the vcpu request infrastructure
and its adoption on ARM, a was for userspace to define which
interrupts get assigned to timer and PMU, a workaround for a nasty
erratum on Cavium HW, and a bit more. Some of the patches touch core
arm64 code, and are acked by the maintainers.

There will be a small clash with the s390 tree, as mentionned by
Stephen Rothwell, as well as with the arm64 tree. Both conflicts are
trivial to resolve, and linux-next got it right (as usual).

Please pull.
