upoke: workaround crippled x32 As PTRACE_POKEUSER is crippled on x32 by design from the very first linux kernel commit v3.4-rc1~33^2~2 when it was introduced, workaround this by using the raw x86_64 syscall instead. * linux/ptrace_pokeuser.c: New file. * linux/x32/ptrace_pokeuser.c: Likewise. * Makefile.am (EXTRA_DIST): Add them. * upoke.c: Include "ptrace_pokeuser.c". (upoke): Use ptrace_pokeuser instead of ptrace. 2018-12-05 18:37:34 +00:00			`/*`
