Merge tag 'hyperv-next-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux
Pull Hyper-V updates from Wei Liu: - a series from Boqun Feng to support page size larger than 4K - a few miscellaneous clean-ups * tag 'hyperv-next-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux: hv: clocksource: Add notrace attribute to read_hv_sched_clock_*() functions x86/hyperv: Remove aliases with X64 in their name PCI: hv: Document missing hv_pci_protocol_negotiation() parameter scsi: storvsc: Support PAGE_SIZE larger than 4K Driver: hv: util: Use VMBUS_RING_SIZE() for ringbuffer sizes HID: hyperv: Use VMBUS_RING_SIZE() for ringbuffer sizes Input: hyperv-keyboard: Use VMBUS_RING_SIZE() for ringbuffer sizes hv_netvsc: Use HV_HYP_PAGE_SIZE for Hyper-V communication hv: hyperv.h: Introduce some hvpfn helper functions Drivers: hv: vmbus: Move virt_to_hvpfn() to hyperv header Drivers: hv: Use HV_HYP_PAGE in hv_synic_enable_regs() Drivers: hv: vmbus: Introduce types of GPADL Drivers: hv: vmbus: Move __vmbus_open() Drivers: hv: vmbus: Always use HV_HYP_PAGE_SIZE for gpadl drivers: hv: remove cast from hyperv_die_event
