Commit51c9c08439("powerpc/kprobes: Implement Optprobes") implemented a powerpc specific version of optinsn in order to workaround the 32Mb limitation for direct branches. Instead of implementing a dedicated powerpc version, use the common optinsn and override the allocation and freeing functions. This also indirectly remove the CLANG warning about is_kprobe_ppc_optinsn_slot() not being use, and the powerpc will now benefit from commit5b485629ba("kprobes, extable: Identify kprobes trampolines as kernel text area") Suggested-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Acked-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/ec5e85f9f9abcfecc959a03495f4a7858eb4d203.1620896780.git.christophe.leroy@csgroup.eu
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.
