#define efi_call_virt6(f, a1, a2, a3, a4, a5, a6) \
efi_call6((void *)(efi.systab->runtime->f), (u64)(a1), (u64)(a2), \
(u64)(a3), (u64)(a4), (u64)(a5), (u64)(a6))

efi_call_virt6() uses efi.systab->runtime->f.
My call needs to use uv_systab, not efi.systab.

How about something like this?

#define efi_call_uv_virt6(a1, a2, a3, a4, a5, a6) \
efi_call6((void *)(__va(uv_systab.function)), (u64)(a1), (u64)(a2), \
(u64)(a3), (u64)(a4), (u64)(a5), (u64)(a6))
