Description
Hi,
as I written in the title it would be a good idea to enable global pages and map the kernel using this flag.
Doing this any kernel mapping would be implicitly duplicated across all the address spaces.
Keep it up!
Waiting UEFI rework's release

Research direction
The issue names no files or tests. Start by locating the bootloader's page-table and kernel-mapping entry points, then determine how global pages should be enabled and propagated across address spaces. Done means kernel mappings are implicitly duplicated across all address spaces without breaking the planned UEFI rework.
