Andrew Boie	76310f6896	x86: make guard pages ro instead of non-present ... Has the same effect of catching stack overflows, but makes debugging with GDB simpler since we won't get errors when inspecting such regions. Making these areas non-present was more than we needed, read-only is sufficient. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>	2019-08-05 13:25:50 +02:00
Andrew Boie	bd709c7322	x86: support very early printk() if desired ... Adapted from similar code in the x86_64 port. Useful when debugging boot problems on actual x86 hardware if a JTAG isn't handy or feasible. Turn this on for qemu_x86.

Charles E. Youse	820ea28f87	arch/x86: move kernel_arch_func.h to ia32/ ... Refactoring 32- and 64-bit subarchitectures, so this file is moved to ia32/ and a new "redirector" header file is introduced. Signed-off-by: Charles E. Youse <charles.youse@intel.com>	2019-07-03 20:01:17 -04:00
