treewide: Convert macro and uses of section(foo) to section("foo")

2020-10-25T21:51:49Z

Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms. Conversion done using the script at: https://lore.kernel.org/lkml/75393e5ddc272dc7403de74d645e6c6e0f4e70eb.camel@perches.com/2-convert_section.pl Signed-off-by: Joe Perches Reviewed-by: Nick Desaulniers Reviewed-by: Miguel Ojeda Signed-off-by: Linus Torvalds

ACPI: Let ACPI know we support Generic Initiator Affinity Structures

2020-10-02T16:51:57Z

Until we tell ACPI that we support generic initiators, it will have to operate in fall back domain mode and all _PXM entries should be on existing non GI domains. This patch sets the relevant OSC bit to make that happen. Signed-off-by: Jonathan Cameron Signed-off-by: Rafael J. Wysocki

arm64: permit ACPI core to map kernel memory used for table overrides

2020-09-30T21:27:51Z

Jonathan reports that the strict policy for memory mapped by the ACPI core breaks the use case of passing ACPI table overrides via initramfs. This is due to the fact that the memory type used for loading the initramfs in memory is not recognized as a memory type that is typically used by firmware to pass firmware tables. Since the purpose of the strict policy is to ensure that no AML or other ACPI code can manipulate any memory that is used by the kernel to keep its internal state or the state of user tasks, we can relax the permission check, and allow mappings of memory that is reserved and marked as NOMAP via memblock, and therefore not covered by the linear mapping to begin with.
