Currently there are two s390 kernel dump config options "CONFIG_ZFCPDUMP"
and "CONFIG_CRASH_DUMP". In order to keep things simple and because the
"CONFIG_ZFCPDUMP" option already has a dependency to "CONFIG_CRASH_DUMP"
remove the CONFIG_ZFCPDUMP option.

successful instead of returning the old value.
- Remove the "volatile" from arch_spinlock_t and arch_rwlock_t

"There are two patches in here:
The first patch greatly improves latency and corrects the memory
ordering in our light-weight atomic locking syscall.
The second patch ratelimits printing of userspace segfaults in the
same way as it's done on other platforms. This fixes a possible DOS
on parisc since it prevents the syslog to grow too fast. For example,
when the debian acl2 package was built on our debian buildd servers,
this package produced lots of gigabytes in syslog in very short time
and thus filled our harddisks, which then turned the server nearly
completely unaccessible and unresponsive"

The arch/powerpc/include/asm/linkage.h is being unintentionally exported
in the kernel headers since commit e1b5bb6d12 (consolidate
cond_syscall and SYSCALL_ALIAS declarations) when
arch/powerpc/include/uapi/asm/linkage.h was deleted but the header-y not
removed from the Kbuild file. This happens because Makefile.headersinst
still checks the old asm/ directory if the specified header doesn't
exist in the uapi directory.
The asm/linkage.h shouldn't ever have been exported anyway. No other
arch does and it doesn't contain anything useful to userland, so remove
the header-y line from the Kbuild file which triggers the export.

Currently the files in /sys/devices/soc0/ show no information about
DRA7. Few userspace programs do depend on this information to make SoC
specific support. So update logic to detect the relevant information and
provide to userspace.

In omap2_common_pm_late_init suspend_set_ops was called to set common
suspend handling functions for all omap platforms. This created two
problems. First, these suspend ops were being set for all platforms,
regardless of whether or not suspend support has been integrated so in
the case of AM33XX, suspend to mem was presented as available but
failed every time. Second, some platforms will need to define a
completely separate set of suspend ops, such as AM33XX, due to
differences from previous omap platforms so there is no need to
always set the common omap ops.
This patch moves the suspend_set_ops call from omap2_common_pm_late_init
into a separate function that then gets called in the omap*_pm_init
functions for each platform.
