Merge tag 'for-linus-4.17-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross: - some fixes of kmalloc() flags - one fix of the xenbus driver - an update of the pv sound driver interface needed for a driver which will go through the sound tree * tag 'for-linus-4.17-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen: xenbus_dev_frontend: Really return response string xen/sndif: Sync up with the canonical definition in Xen xen: xen-pciback: Replace GFP_ATOMIC with GFP_KERNEL in pcistub_reg_add xen: xen-pciback: Replace GFP_ATOMIC with GFP_KERNEL in xen_pcibk_config_quirks_init xen: xen-pciback: Replace GFP_ATOMIC with GFP_KERNEL in pcistub_device_alloc xen: xen-pciback: Replace GFP_ATOMIC with GFP_KERNEL in pcistub_init_device xen: xen-pciback: Replace GFP_ATOMIC with GFP_KERNEL in pcistub_probe
