um: remove custom definition of mk_pte()

2025-05-12T00:48:03Z

Move the pfn_pte() definitions from the 2level and 4level files to the generic pgtable.h and delete the custom definition of mk_pte() so that we use the central definition.

um: Rename _PAGE_NEWPAGE to _PAGE_NEEDSYNC

2024-10-23T07:52:49Z

The _PAGE_NEWPAGE bit does not really indicate that this is a new page, but rather whether this entry needs to be synced or not. Renaming it to _PAGE_NEEDSYNC will make it more clear how everything ties together.

um: Switch to 4 level page tables on 64 bit

2024-10-10T11:37:22Z

The larger memory space is useful to support more applications inside UML. One example for this is ASAN instrumentation of userspace applications which requires addresses that would otherwise not be available.
