Subject[PATCH 0/5] X86/XEN: Merge x86_init.paging.pagetable_setup_start and x86_init.paging.pagetable_setup_done PVOPS and document the semantic
Date
Currently the definition of x86_init.paging.pagetable_setup_start and
x86_init.paging.pagetable_setup_done is twisted and not really well
defined (in terms of prototypes desired). More specifically:
pagetable_setup_start:
* it is a nop on x86_32
* it is a nop for the XEN case
* cleans up the boot time page table in the x86_64 case

pagetable_setup_done:
* it is a nop on x86_32
* sets up accessor functions for pagetable manipulation, for the
XEN case
* it is a nop on x86_64

Most of this logic can be skipped by creating a new PVOPS that can handle
pagetable setup and pre/post operations on it.
The new PVOPS must be called only once, during boot-time setup and
after the direct mapping for physical memory is available.

Attilio Rao (5):
XEN: Remove the base argument from
x86_init.paging.pagetable_setup_done PVOPS
XEN: Remove the base argument from
x86_init.paging.pagetable_setup_start PVOPS
X86/XEN: Introduce the x86_init.paging.pagetable_init() PVOPS
X86/XEN: Retire now unused x86_init.paging.pagetable_setup_start and
x86_init.paging.pagetable_setup_done PVOPS
X86/XEN: Add few lines explaining simple semantic for
x86_init.paging.pagetable_init PVOPS
