Just an intermediate step to make reviewing easier.
These files are identical copies of the existing headers.

To: x86; +Cc: linux-kernel, Arnd Bergmann
For these nine header files, the asm-generic version should
be semantically identical to what is in x86. Change the
contents to be binary identical, for better review.

From: Arnd Bergmann @ 2009-05-15 16:32 UTC (permalink / raw)
To: x86; +Cc: linux-kernel, Arnd Bergmann
In x86, mman.h, module.h, scatterlist.h, types.h and ucontext.h
can use the asm-generic version by just defining the x86
specific parts locally and falling back on the generic code
for the common bits.
This patch illustrates the differences between the x86 and
asm-generic versions by changing a file that is initially
identical to the x86 version to one that is identical
to the asm-generic version.

From: Arnd Bergmann @ 2009-05-15 16:32 UTC (permalink / raw)
To: x86; +Cc: linux-kernel, Arnd Bergmann
This patch turned out more controversial than expected
and may get dropped in the future. I'm including it
for reference anyway.
The user_termio_to_kernel_termios and kernel_termios_to_user_termio
functions on x86 are lacking error checking from get_user and
are not portable to big-endian systems, so the asm-generic
header has to differ in this regard.

From: Arnd Bergmann @ 2009-05-15 16:32 UTC (permalink / raw)
To: x86; +Cc: linux-kernel, Arnd Bergmann
All files that have been made identical to the asm-generic
version in the previous patches can now be removed,
guaranteeing that this does not introduce semantic changes.

- * The shmid64_ds structure for x86 architecture.

- * between kernel and user space.
- *
- * shmid64_ds was originally meant to be architecture specific, but
- * everyone just ended up making identical copies without specific
- * optimizations, so we may just as well all use the same one.
- *
- * 64 bit architectures typically define a 64 bit __kernel_time_t,
- * so they do not need the first two padding words.
- * On big-endian systems, the padding is in the wrong place.

- * - 64-bit time_t to solve y2038 problem
- * - 2 miscellaneous 32-bit values
