[PATCH] Fix sys_ptrace on ia64

[Andreas Schwab]

On ia64 the PTRACE_PEEK{TEXT,DATA,USER} operations of ptrace return the
data directly instead of storing it through a supplied pointer.

	* process.c (sys_ptrace) [IA64]: For PTRACE_PEEKDATA,
	PTRACE_PEEKTEXT and PTRACE_PEEKUSER the data is returned directly.
