x86/ptrace: make genregs[32]_get/set more robust The loop condition is fragile: we compare an unsigned value to zero, and then decrement it by something larger than one in the loop. All the callers should be passing in appropriately aligned buffer lengths, but it's better to just not rely on it, and have some appropriate defensive loop limits.
