s390/cmpxchg: select HAVE_CMPXCHG_LOCAL option

2012-05-30T07:07:59+00:00

Now that hopefully all cmpxchg/xchg bugs have been fixed select
HAVE_CMPXCHG_LOCAL option which uncovered a couple of bugs on s390.

The only call site which is affected seems to be within mm/vmstat.c.

2012-05-24T20:29:46+00:00

Pull timer updates from Thomas Gleixner.

Various trivial conflict fixups in arch Kconfig due to addition of
unrelated entries nearby.  And one slightly more subtle one for sparc32
(new user of GENERIC_CLOCKEVENTS), fixed up as per Thomas.

  not changing any of the real cpu hotplug horrors yet.  I wish I'd had
  something more substantial for 3.5, but I underestimated the lurking
  horror..."

timers: Fixup the Kconfig consolidation fallout

2012-05-21T21:43:46+00:00

Sigh, I missed to check which architecture Kconfig files actually
include the core Kconfig file. There are a few which did not. So we
broke them.

Instead of adding the includes to those, we are better off to move the
include to init/Kconfig like we did already with irqs and others.

This does not change anything for the architectures using the old
style periodic timer mode. It just solves the build wreckage there.

For those architectures which use the clock events infrastructure it
moves the include of the core Kconfig file to "General setup" which is
a way more logical place than having it at random locations specified
by the architecture specific Kconfigs.

s390/Kconfig: add HAVE_MARCH_[ARCH]_FEATURES Kconfig symbols

2012-05-16T12:42:43+00:00

Add HAVE_MARCH_[ARCH]_FEATURES Kconfig symbols. Whenever there is code that
needs an instruction that is only present beginning with a hardware generation
the #ifdef chain can become quite long.
To avoid this add the new Kconfig symbols which are selected if the kernel
gets compiled for at least the specified symbol.
If for example the kernel gets compiled for z196 this means that also all
symbols for all previous architure features are set.

s390/ipl: remove builtin tape ipl code

2012-05-16T12:42:40+00:00

Remove the builtin tape ipl code. If somebody really wants to create a
tape which can be ipl'ed from, then this can be achieved by using zipl.
zipl can write an ipl record to a tape device and aftwards the kernel
image must be written to tape.
The steps are described in the "Linux on System z - Device Drivers,
Features, and Commands" book (SC33-8411).
