Subject: x86: ptrace_request peekdata/pokedata
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=16c3e389e7a7254ff8dc7029ac4fbe996c3c75bf;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

x86: ptrace_request peekdata/pokedata

This makes ptrace_request handle {PEEK,POKE}{TEXT,DATA} directly.
Every arch_ptrace that could call generic_ptrace_peekdata already
has a default case calling ptrace_request, so this keeps things
simpler for the arch code.
