[PATCH] x86/kvm: Make parse_no_xxx __init for kvm

From: Dou Liyang
Date: Tue Jan 16 2018 - 22:47:18 EST


The early_param() is only called during kernel initialization, So Linux
marks the functions of it with __init macro to save memory.

But it forgot to mark the parse_no_kvmapf/stealacc/kvmclock_vsyscall,
So, Make them __init as well.
