Continuing work by Ard Biesheuvel to improve the x86 early startup # code, with the long-term goal to make it position independent: # # - Get rid of early accesses to global objects, either by moving # them to the stack, deferring the access until later, or dropping # the globals entirely # # - Move all code that runs early via the 1:1 mapping into # .head.text, and move code that does not out of it, so that build # time checks can be added later to ensure that no inadvertent # absolute references were emitted into code that does not # tolerate them # # - Remove fixup_pointer() and occurrences of __pa_symbol(), which # rely on the compiler emitting absolute references, which is not # guaranteed # # - Improve the early console code # # - Add early console message about ignored NMIs, so that users are at # least warned about their existence - even if we cannot do anything # about them # # - Improve the kexec code's kernel load address handling # # - Enable more X86S (simplified x86) bits # # - Simplify early boot GDT handling # # - Micro-optimize the boot code a bit # # -
