Hi all,

this series introduces PV wallclock time support on arm and arm64.

Changes in v3:
- use ktime_get_ns instead of calling into the arch_timer functions
directly
- read the wallclock from the late_initcall
- s/%llu.%0u/%llu.%09u
- in xen_pvclock_gtod_notify use the passed struct timekeeper pointer
rather than calling __current_kernel_time64
- use the passed struct timekeeper pointer to get the system time too
- drop introduce __current_kernel_time64

Changes in v2:
- introduce __current_kernel_time64
- rename dom0_op to platform_op
- introduce XENPF_settime64
- extend pvclock_wall_clock with sec_hi
- properly convert arch_timer ticker to nsec
- use timespec64 interfaces
- use sec_hi to get a 64-bit seconds value
- use XENPF_settime64
- rename dom0_op to platform_op

Stefano Stabellini (6):
xen: rename dom0_op to platform_op
xen/arm: introduce HYPERVISOR_platform_op on arm and arm64
xen: introduce XENPF_settime64
arm: extend pvclock_wall_clock with sec_hi
xen/arm: introduce xen_read_wallclock
xen/arm: set the system time in Xen via the XENPF_settime64 hypercall
