commit b94d360e4aa66d626ad5a0acde683ae9a9c71729 Author: Andrew Turner <[email protected]> AuthorDate: 2021-09-20 08:55:44 +0000 Commit: Andrew Turner <[email protected]> CommitDate: 2021-09-20 10:34:04 +0000 Add ELF macros found in the aaelf64 spec The arm64 aaelf64 spec [0] has DT_AARCH64_ that could be used with dynamic linking. It also adds GNU_PROPERTY_AARCH64_FEATURE_1_AND used to tell the kernel which CPU features the binary is compatible with, but does not require to execute correctly. Add these values so the kernel and elf tools can make use of them.
