2019-10-30support using KVM_MEM_READONLY for arm64 regionslubinszARM
On Arm platform, "setMemoryRegion" has extra permission checks. In virt/kvm/arm/mmu.c: kvm_arch_prepare_memory_region() .... if (writable && !(vma->vm_flags & VM_WRITE)) { ret = -EPERM; break; } .... So, for Arm platform, the "flags" for kvm_memory_region is required. And on x86 platform, the "flags" can be always set as '0'.

2019-09-24gvisor: change syscall.RawSyscall to syscall.RawSyscall6 where requiredgVisor bot
Before https://golang.org/cl/173160 syscall.RawSyscall would zero out the last three register arguments to the system call. That no longer happens. For system calls that take more than three arguments, use RawSyscall6 to ensure that we pass zero, not random data, for the additional arguments. PiperOrigin-RevId: 271062527
