  KVM: x86: fix APIC page invalidation (2017-12-06 16:10:34 +0100)

----------------------------------------------------------------
KVM fixes for v4.15-rc3

ARM:
 * A number of issues in the vgic discovered using SMATCH
 * A bit one-off calculation in out stage base address mask (32-bit and
   64-bit)
 * Fixes to single-step debugging instructions that trap for other
   reasons such as MMMIO aborts
 * Printing unavailable hyp mode as error
 * Potential spinlock deadlock in the vgic
 * Avoid calling vgic vcpu free more than once
 * Broken bit calculation for big endian systems

s390:
 * SPDX tags
 * Fence storage key accesses from problem state
 * Make sure that irq_state.flags is not used in the future

x86:
 * Intercept port 0x80 accesses to prevent host instability (CVE)
 * Use userspace FPU context for guest FPU (mainly an optimization that
   fixes a double use of kernel FPU)
 * Do not leak one page per module load
 * Flush APIC page address cache from MMU invalidation notifiers
