Merge tag 'kvm-arm-fixes-for-v4.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm
KVM/ARM Fixes for v4.15.
Fixes:
- 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
