Dimitry Andric 7756b8f25e xen: Fix warning by adding KERNBASE to modlist_paddr before casting ... Clang 13 produces the following warning for hammer_time_xen(): sys/x86/xen/pv.c:183:19: error: the pointer incremented by -2147483648 refers past the last possible element for an array in 64-bit address space containing 256-bit (32-byte) elements (max possible 576460752303423488 elements) [-Werror,-Warray-bounds] (vm_paddr_t)start_info->modlist_paddr + KERNBASE; ^ ~~~~~~~~ sys/xen/interface/arch-x86/hvm/start_info.h:131:5: note: array 'modlist_paddr' declared here uint64_t modlist_paddr; /* Physical address of an array of */ ^ This is because the expression first casts start_info->modlist_paddr to struct hvm_modlist_entry * (via vmpaddr_t), and *then* adds KERNBASE, which is then interpreted as KERNBASE * sizeof(struct hvm_modlist_entry). Instead, parenthesize the addition to get the intended result, and cast it to struct hvm_modlist_entry * afterwards. Also remove the cast to vmpaddr_t since it is not necessary.
