Hi Linus,

please pull from the 'for-linus' branch of

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus

to receive the following updates:

The big one is support for fake NUMA, splitting a really large machine
in more manageable piece improves performance in some cases, e.g. for
a KVM host.

The FICON Link Incident handling has been improved, this helps the
operator to identify degraded or non-operational FICON connections.

The save and restore of floating point and vector registers has been
overhauled to allow the future use of vector registers in the kernel.

A few small enhancement, magic sys-requests for the vt220 console via SCLP,
some more assembler code has been converted to C, the PCI error handling
is improved.

And the usual cleanup and bug fixing.
