HV_CLOCK_SIZE is not used anywhere anymore, can be deleted. > +#define HVC_BOOT_ARRAY_SIZE \ > + (PAGE_SIZE / sizeof(struct pvclock_vsyscall_time_info)) This works, because sizeof(struct pvclock_vsyscall_time_info)) == 64 bytes, but static assert that verifies that IS_ALIGNED(PAGESIZE, sizeof(struct pvclock_vsyscall_time_info)) would guarantee that no random data is ever exposed to vdso.
