Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
"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"
