However, the most disappointing change here is that we've had to bump ARCH_DMA_MINALIGN back to 128 bytes thanks to Qualcomm's "Kryo" CPU, which ended up in the MSM8996 mobile SoC. Still, at least we're now aware of this design and one of the hardware designers confirmed the L2 cacheline size for us. Summary: - Fix instrumentation annotations for entry code - Ensure kernel MTE state is restored correctly on resume from suspend - Fix MTE fault from new strlen() routine - Fallback to byte-wise accesses on initial uaccess fault - Bump Clang requirement for BTI - Revert ARCH_DMA_MINALIGN back to 128 bytes (shakes fist at Qualcomm)" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: entry: fix KCOV suppression arm64: entry: add missing noinstr arm64: mte: fix restoration of GCR_EL1 from suspend arm64: Avoid premature usercopy failure arm64: Restrict ARM64_BTI_KERNEL to clang 12.0.0 and newer Revert "arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES)" arm64: Add missing header <asm/smp.h> in two files arm64: fix strlen() with CONFIG_KASAN_HW_TAGS |

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.
