  KVM: SVM: Fix SEV LAUNCH_SECRET command (2018-02-24 02:24:13 +0100)

----------------------------------------------------------------
s390:
- optimization for the exitless interrupt support that was merged in 4.16-rc1
- improve the branch prediction blocking for nested KVM
- replace some jump tables with switch statements to improve expoline performance
- fixes for multiple epoch facility

ARM:
- fix the interaction of userspace irqchip VMs with in-kernel irqchip VMs
- make sure we can build 32-bit KVM/ARM with gcc-8.

x86:
- fixes for AMD SEV
- fixes for Intel nested VMX, emulated UMIP and a dump_stack() on VM startup
- fixes for async page fault migration
- small optimization to PV TLB flush (new in 4.16-rc1)
- syzkaller fixes

Generic:
- compiler warning fixes
- syzkaller fixes
- more improvements to the kvm_stat tool

Two more small Spectre fixes are going to reach you via Ingo.
