Jann Horn 7be4412721 x86/insn-eval: Add support for 64-bit kernel mode ... To support evaluating 64-bit kernel mode instructions: * Replace existing checks for user_64bit_mode() with a new helper that checks whether code is being executed in either 64-bit kernel mode or 64-bit user mode. * Select the GS base depending on whether the instruction is being evaluated in kernel mode.
