Subject: arm64: ptrace: remove obsolete ptrace request numbers from user headers
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=27aa55c5e5123fa8b8ad0156559d34d7edff58ca;p=openwrt%2Fstaging%2Fblogic.git

arm64: ptrace: remove obsolete ptrace request numbers from user headers

The use of regsets has removed the need for many private ptrace requests,
so remove the corresponding definitions from the user-visible ptrace.h
