[PATCH 0/2] PUD/PGDIR entries for linear mapping

2020-06-03 Thread Alexandre Ghiti
This small patchset intends to use PUD/PGDIR entries for linear mapping in order to better utilize TLB. At the moment, only PMD entries can be used since on common platforms (qemu/unleashed), the kernel is loaded at DRAM + 2MB which dealigns virtual and physical addresses and then prevents the
