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 */
x86, mpparse, x86/acpi, x86/PCI, x86/dmi, SFI: Use memremap() for RAM mappings The ioremap() function is intended for mapping MMIO. For RAM, the memremap() function should be used. Convert calls from ioremap() to memremap() when re-mapping RAM. This will be used later by SME to control how the encryption mask is applied to memory mappings, with certain memory locations being mapped decrypted vs encrypted.
