SUCCESS d07c7f1ed61789e175fa975134855be32263be2c is the first bad commit commit d07c7f1ed61789e175fa975134855be32263be2c Author: Andy Lutomirski Date: Tue Jul 15 18:34:20 2014 -0700 x86,kaslr: Use MSR_KVM_GET_RNG_SEED for KASLR if available It's considerably better than any of the alternatives on KVM. Rather than reinventing all of the cpu feature query code, this fixes native_cpuid to work in PIC objects. I haven't combined it with boot/cpuflags.c's cpuid implementation: including asm/processor.h from boot/cpuflags.c results in a flood of unrelated errors, and fixing it might be messy.
