Rob Bradford	c47e3b8689	gdb: Do not use VmmOps for memory manipulation ... We don't use the VmmOps trait directly for manipulating memory in the core of the VMM as it's really designed for the MSHV crate to handle instruction decoding. As I plan to make this trait MSHV specific to allow reduced locking for MMIO and PIO handling when running on KVM this use should be removed.
