[PATCH v2 0/4] x86: clear XD_DISABLED flag on Intel to regain NX
This will clear the MSR_IA32_MISC_ENABLE_XD_DISABLE bit so that NX cannot be inappropriately controlled by the BIOS on Intel CPUs. If NX actually needs to be disabled, "noexec=off" can be used. Based on feedback from HPA, this was reworked to extend the existing "verify_cpu" routines, and to more tightly confine... 19 Jun 2010 02:39
