- Improve performance of Spectre-v2 mitigation on Falkor CPUs (if you're lucky enough to have one) - Select HAVE_MOVE_PMD. This has been shown to improve mremap() performance, which is used heavily by the Android runtime GC, and it seems we forgot to enable this upstream back in 2018. - Ensure linker flags are consistent between LLVM and BFD - Fix stale comment in Spectre mitigation rework - Fix broken copyright header - Fix KASLR randomisation of the linear map - Prevent arm64-specific prctl()s from compat tasks (return -EINVAL) -----BEGIN PGP SIGNATURE----- iQFEBAABCgAuFiEEPxTL6PPUbjXGY88ct6xw3ITBYzQFAl+QEPAQHHdpbGxAa2Vy bmVsLm9yZwAKCRC3rHDchMFjNE8jB/0YNYKO9mis/Xn5KcOCwlg4dbc2uVBknZXD f7otEJ6SOax2HcWz8qJlrJ+qbGFawPIqFBUAM0vU1VmoyctIoKRFTA8ACfWfWtnK QBfHrcxtJCh/GGq+E1IyuqWzCjppeY/7gYVdgi1xDEZRSaLz53MC1GVBwKBtu5cf X2Bfm8d9+PSSnmKfpO65wSCTvN3PQX1SNEHwwTWFZQx0p7GcQK1DdwoobM6dRnVy +e984ske+2a+nTrkhLSyQIgsfHuLB4pD6XdM/UOThnfdNxdQ0dUGn375sXP+b4dW 7MTH9HP/dXIymTcuErMXOHJXLk/zUiUBaOxkmOxdvrhQd0uFNFIc =e9p9 -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull more arm64 updates from Will Deacon: "A small selection of further arm64 fixes and updates.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
