Hi,

The top of the master branch has been tagged [1] as part of the integration drop 1.8.0.

Below is the changelog for kernel users, since the previous integration drop (1.7.0).

---------

* [Issue #4] The BPF syscall interface has been adapted to operate on   full capabilities, while retaining backwards-compatibility with   existing arm64 binaries (via 64-bit compat). Please refer to   include/uapi/linux/bpf.h [2] for a full list of modified uapi structs.

* [Issue #5, #58] User-provided capabilities are now always checked when   user memory is accessed (standard uaccess routines such as   copy_from_user() now use capability-based loads and stores to perform   the access). As a result, passing invalid capabilities to syscalls   will typically lead to the syscall failing with -EFAULT. New Morello   kselftests have been added to ensure that this capability checking   occurs as expected.

* The branch has been rebased on the 6.7 upstream release. The   morello.rst document has moved under Documentation/arch/arm64 as a   result, and a few uapi adaptations have been added for io_uring   features that appeared upstream since 6.4. For more details, please   refer to this email [3].

* Minor internal refactoring and cleanups related to 64-bit compat   support.
