Andreas Kling 9c0836ce97 Kernel: Enable x86 UMIP (User Mode Instruction Prevention) if supported ... This prevents code running outside of kernel mode from using the following instructions: * SGDT - Store Global Descriptor Table * SIDT - Store Interrupt Descriptor Table * SLDT - Store Local Descriptor Table * SMSW - Store Machine Status Word * STR - Store Task Register There's no need for userspace to be able to use these instructions so let's just disable them to prevent information leakage.		2020-01-01 13:21:15 +01:00
