They fix very early boot failures with KASLR where the early mapping of the kernel is incorrect, so the failure mode looks like a hang with no output. There's also a signal-handling fix when a uaccess routine faults with a fatal signal pending, which could be used to create unkillable user tasks using userfaultfd and finally a state leak fix for the floating pointer registers across a call to exec(). We're still seeing some random issues crop up (inode memory corruption and spinlock recursion) but we've not managed to reproduce things reliably enough to debug or bisect them yet. Summary: - Fix very early boot failures with KASLR enabled - Fix fatal signal handling on userspace access from kernel - Fix leakage of floating point register state across exec()" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: kaslr: Adjust the offset to avoid Image across alignment boundary arm64: kaslr: ignore modulo offset when validating virtual displacement arm64: mm: abort uaccess retries upon fatal signal arm64: fpsimd: Prevent registers leaking across exec |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
