Make trampoline_pgd a proper kernel page table, it currently only includes the kernel text and module space mapping. One new feature of trampoline_pgd is that it now has mappings for the physical I/O device addresses, which are inserted at ioremap() time. Some broken implementations of EFI firmware require these mappings to always be around. Acked-by: Jan Beulich Signed-off-by: Matt Fleming --- Reading git-diff-tree failed
