The patch titled
Split i386 and x86_64 ptrace.h
has been removed from the -mm tree. Its filename is
split-i386-and-x86_64-ptraceh.patch
This patch was dropped because Andi changes broke it
------------------------------------------------------
Subject: Split i386 and x86_64 ptrace.h
From: Jeff Dike <jdike@xxxxxxxxxxx>
The use of SEGMENT_RPL_MASK in the i386 ptrace.h introduced by
x86-allow-a-kernel-to-not-be-in-ring-0.patch will break 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.
This patch was run by linux-arch yesterday with no comment.
