Subject: [RFC PATCH v3 00/11] powerpc: Add support for ftrace direct and BPF trampolines
Date: Fri, 21 Jun 2024 00:24:03 +0530 [thread overview]
Message-ID: <cover.1718908016.git.naveen@kernel.org> (raw)
This is v3 of the patches posted here:
http://lkml.kernel.org/r/cover.1718008093.git.naveen@kernel.org
Since v2, I have addressed review comments from Steven and Masahiro
along with a few fixes. Patches 7-11 are new in this series and add
support for ftrace direct and bpf trampolines.
This series depends on the patch series from Benjamin Gray adding
support for patch_ulong():
http://lkml.kernel.org/r/20240515024445.236364-1-bgray@linux.ibm.com
