Pull arm64 fixes from Will Deacon: "Three arm64 fixes. The main one is a fix to the way in which we evaluate the macro arguments to our uaccess routines, which we _think_ might be the root cause behind some unkillable tasks we've seen in the Android arm64 CI farm (testing is ongoing). In any case, it's worth fixing. Other than that, we've toned down an over-zealous VM_BUG_ON() and fixed ftrace stack unwinding in a bunch of cases. Summary: - Evaluate uaccess macro arguments outside of the critical section - Tighten up VM_BUG_ON() in pmd_populate_kernel() to avoid false positive - Fix ftrace stack unwinding using HAVE_FUNCTION_GRAPH_RET_ADDR_PTR" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: uaccess: avoid blocking within critical sections arm64: mm: Fix VM_BUG_ON(mm != &init_mm) for trans_pgd arm64: ftrace: use HAVE_FUNCTION_GRAPH_RET_ADDR_PTR
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.
