According to UEFI 2.6 section 7.5.3, the capsule should be in contiguous virtual memory and firmware may consume the capsule immediately. To correctly implement this functionality, the kernel driver needs to vmap the entire capsule at the time it is made available to firmware. The virtual allocation of the capsule update has been changed from kmap, which was only allocating the first page of the update, to vmap, and allocates the entire data payload.
