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
KVM: arm/arm64: Fix broken GICH_ELRSR big endian conversion
We are incorrectly rearranging 32-bit words inside a 64-bit typed value
for big endian systems, which would result in never marking a virtual
interrupt as inactive on big endian systems (assuming 32 or fewer LRs on
the hardware). Fix this by not doing any word order manipulation for
the typed values.
