All frame blocks seem to be marked as "uncacheable"

While debugging another issue and looking at the frame accounting blocks, it seems that all blocks were marked as "uncacheable". They should be marked as whatever the bootloader got from UEFI, so double check where that uncacheable flag is coming from.

Re-reading the UEFI flags, this flag marks the memory region as supporting being marked as uncacheable, not that it is never cacheable.
