x86: Fix ASM_X86__ header guards Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

x86/dmi: fix dmi_alloc() section mismatches Impact: section mismatch fix Ingo reports these warnings: > WARNING: vmlinux.o(.text+0x6a288e): Section mismatch in reference from > the function dmi_alloc() to the function .init.text:extend_brk() > The function dmi_alloc() references > the function __init extend_brk(). > This is often because dmi_alloc lacks a __init annotation or the > annotation of extend_brk is wrong. dmi_alloc() is a static inline, and so should be immune to this kind of error. But force it to be inlined and make it __init anyway, just to be extra sure. All of dmi_alloc()'s callers are already __init.

dmi: clean-up dmi helper declarations The declaration of dmi helper functions is a bit messy and inconsistent at the moment: * On ia64 they are declared in <asm/io.h>. * On x86-64 they are declared in <asm/dmi.h>. * On i386 they are declared both in <asm/io.h> and <asm/dmi.h>. Fix the header files so that the dmi helper functions are consistently defined in <asm/dmi.h>.

/* Use early IO mappings for DMI because it's initialized early */
firmware/dmi_scan: generalize for use by other archs This patch makes a couple of changes to the SMBIOS/DMI scanning code so it can be used on other archs (such as ARM and arm64): (a) wrap the calls to ioremap()/iounmap(), this allows the use of a flavor of ioremap() more suitable for random unaligned access; (b) allow the non-EFI fallback probe into hardcoded physical address 0xF0000 to be disabled.
