[Xen-ia64-devel] [patch 00/15] ia64: kexec: Map EFI memory in the same location as Linux v20080715

[Simon Horman <horms@xxxxxxxxxxxx>]

Hi,

This series is what I believe to be a fairly complete set of patches to map
EFI memory into the same location that Linux does.  The memory is protected
by an RID so that it doesn't conflict with domain memory - which also
protects it from malicious access from HVM domains.

The primary motivation for this is that EFI memory can only be mapped once
- a restriction in the EFI specification. Thus for kexec betwen Xen and
Linux, inluding kdump of Xen (into Linux), EFI memory needs to be mapped in
the same location in both Xen and Linux.


This new series only maps PAL code when making EFI, PAL or SAL calls.

I have tested these patches on a RX 2620.
I am hoping for more reviews and tests :-)

I recommend testing these patches using:
