[PATCH] uml: x86_64 ptrace fixes
This patch fixes some missing ptrace bits on x86_64. PTRACE_ARCH_PRCTL is
hooked up and implemented. This required generalizing arch_prctl_skas
slightly to take a task_struct to modify. Previously, it always operated on
current.
Reading and writing the debug registers is also enabled by un-ifdefing the
code that implements that. It turns out that x86_64 is identical to i386, so
the same code can be used.
