KVM: x86 emulator: Add wrappers for easily defining opcodes
Browse files Browse the repository at this point in the history 
Once 'struct opcode' grows, its initializer will become more complicated.
Wrap the simple initializers in a D() macro, and replace the empty initializers
with an even simpler N macro.
