x86: remove all now-duplicate header files
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de> LKML-Reference: <cover.1245354003.git.arnd@arndb.de> Signed-off-by: H. Peter Anvin <hpa@zytor.com>

7 * The shmid64_ds structure for x86 architecture.
8 * Note extra padding because this structure is passed back and forth
9 * between kernel and user space.
10 *
11 * shmid64_ds was originally meant to be architecture specific, but
12 * everyone just ended up making identical copies without specific
13 * optimizations, so we may just as well all use the same one.
14 *
15 * 64 bit architectures typically define a 64 bit __kernel_time_t,
16 * so they do not need the first two padding words.
17 * On big-endian systems, the padding is in the wrong place.
18 *
19 *
20 * Pad space is left for:
21 * - 64-bit time_t to solve y2038 problem
22 * - 2 miscellaneous 32-bit values
