Linux kernel source tree
b5ecc19e68
The arm64 stacktrace code can be used in kprobe context, and so cannot be safely probed. Some (but not all) of the unwind functions are annotated with `NOKPROBE_SYMBOL()` to ensure this, with others markes as `__always_inline`, relying on the top-level unwind function being marked as `noinstr`. This patch has stacktrace.c consistently mark the internal stacktrace functions as `__always_inline`, removing the need for NOKPROBE_SYMBOL() as the top-level unwind function (arch_stack_walk()) is marked as `noinstr`. This is more consistent and is a simpler pattern to follow for future additions to stacktrace.c. There should be no functional change as a result of this patch.

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.
