Subject: x86: ptrace_request peekdata/pokedata
X-Git-Tag: v2.6.25-rc1~1143^2~516
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=16c3e389e7a7254ff8dc7029ac4fbe996c3c75bf;p=linux-2.6

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.
