[Xen-devel] [PATCH v2 0/7] Xen wallclock on arm and arm64

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi all,

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


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
