Alexey Dobriyan 2bcd57ab61 headers: utsname.h redux
* remove asm/atomic.h inclusion from linux/utsname.h --
   not needed after kref conversion
 * remove linux/utsname.h inclusion from files which do not need it

NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
due to some personality stuff it _is_ needed -- cowardly leave ELF-related
headers and files alone.

Heiko Carstens e86a6ed63f [S390] Get rid of cpuid.h header file.
Merge cpuid.h header file into cpu.h.
While at it convert from typedef to struct declaration and also
convert cio code to use proper lowcore structure instead of casts.

Frank Munzert 159d1ff8f6 [S390] Use csum_partial in checksum.h
The cksm function in system.h is duplicate to csum_partial in checksum.h.
Remove cksm and use csum_partial instead.

Frank Munzert 12e0c95e0c [S390] zfcpdump: Make SCSI disk dump tool recognize storage holes
The kernel part of zfcpdump establishes a new debugfs file zcore/memmap
which exports information on memory layout (start address and length of each
memory chunk) to its userspace counterpart.

Michael Holzheu 53a0868cb4 [S390] zcore: fix inline assembly in memcpy_real()
memcpy_real uses the mvcle instruction. This instruction alters all used
registers (source, destination and 2 x count). Therefore we have to flag
those registers as input/output registers (+d). In addition to that, we
have to specify, that we read from memory designated by "src" and write to
memory designated by "dest".

Michael Holzheu 411ed32257 [S390] zfcpdump support.
s390 machines provide hardware support for creating Linux dumps on SCSI
disks. For creating a dump a special purpose dump Linux is used. The first
32 MB of memory are saved by the hardware before the dump Linux is
booted. Via an SCLP interface, the saved memory can be accessed from
Linux. This patch exports memory and registers of the crashed Linux to
userspace via a debugfs file. For more information refer to
Documentation/s390/zfcpdump.txt, which is included in this patch.
