x86/boot: Fix memremap() related build failure

2017-07-20T09:37:58Z

The following commit: 5997efb96756 ("x86/boot: Use memremap() to map the MPF and MPC data") causes new build failures on certain randconfigs: drivers/sfi/sfi_core.c: In function ‘sfi_map_memory’: drivers/sfi/sfi_core.c:104:10: error: implicit declaration of function ‘memremap’ [-Werror=implicit-function-declaration] drivers/sfi/sfi_core.c:104:31: error: ‘MEMREMAP_WB’ undeclared (first use in this function) This is a case of parasitic header dependencies: the sfi_core.c file indirectly includes for typical - but not all configs. Including explicitly solves the build failure.

x86, mpparse, x86/acpi, x86/PCI, x86/dmi, SFI: Use memremap() for RAM mappings

2017-07-18T09:37:58Z

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.

The following warnings can be seen in W=1 builds, because the original sfi_acpi.[ch] header inclusions are incorrect: include/linux/sfi_acpi.h:72:2: error: implicit declaration of function 'acpi_table_parse' [-Werror=implicit-function-declaration] drivers/sfi/sfi_acpi.c:154:5: warning: no previous prototype for 'sfi_acpi_table_parse' [-Wmissing-prototypes] Fix linux/sfi_acpi.h and modify drivers/sfi/sfi_acpi.c accordingly.

ACPI: Clean up inclusions of ACPI header files

2013-12-07T00:03:14Z

Replace direct inclusions of , and , which are incorrect, with inclusions and remove some inclusions of those files that aren't necessary. First of all, , and should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that be included prior to so that the acpi_pci_root declarations the latter depends on are always there. And which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including as appropriate.
