License cleanup: add SPDX license identifier to uapi header files with no license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does not cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does not fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

MIPS: AT_HWCAP aux vector infrastructure In order for userland to determine whether various features are safe to use, it will need to know both that the hardware supports those features and that the kernel is recent enough & configured appropriately to support them. For example under the O32 modeless FP proposal the dynamic linker & ifunc resolvers will need this information. The kernel is the only thing in a position to know availability accurately, so the kernel needs to provide the information to userland. This patch introduces the infrastructure to provide the AT_HWCAP aux vector to userland in order to provide that information. It also defines the 2 currently specified flags, which indicate MIPSr6 & MSA support.

MIPS: Add crc instruction support flag to elf_hwcap Indicate that CRC32 and CRC32C instuctions are supported by the CPU through elf_hwcap flags. This will be used by a follow-up commit that introduces crc32(c) crypto acceleration modules and is required by GENERIC_CPU_AUTOPROBE feature.

MIPS: elf_hwcap: Export userspace ASEs A Golang developer reported MIPS hwcap isn't reflecting instructions that the processor actually supported so programs can't apply optimized code at runtime. Thus we export the ASEs that can be used in userspace programs.
