The use of SEGMENT_RPL_MASK in the i386 ptrace.h introduced by x86-allow-a-kernel-to-not-be-in-ring-0.patch broke the UML build, as UML includes the underlying architecture's ptrace.h, but has no easy access to the x86 segment definitions. Rather than kludging around this, as in the past, this patch splits the userspace-usable parts, which are the bits that UML needs, of ptrace.h into ptrace-abi.h, which is included back into ptrace.h. Thus, there is no net effect on i386. As a side-effect, this creates a ptrace header which is close to being usable in /usr/include. x86_64 is also treated in this way for consistency. There was some trailing whitespace there, which is cleaned up.
