Subject: [GIT PULL] s390 patches for 4.14-rc6

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:

Two bug fixes:

 * A fix for cputime accounting vs CPU hotplug

 * Add two options to zfcpdump_defconfig to make SCSI dump work again

Christian Borntraeger (1):
      s390/cputime: fix guest/irq/softirq times after CPU hotplug

Dimitri John Ledkov (1):
      s390: fix zfcpdump-config
