This series is based on Karim's ARM support commits, further broken up into smaller patches. The comments from last time should be addressed now, plus a few other things: - The biggest change in this roll is that it can now cope with being loaded at different addresses, and so works on Xen 4.4 and Xen/unstable. It does this by configuring the MMU to map virtual address x to physical address (x + physical_address_offset), where physical_address_offset is calculated to make everything appear where the linker is expecting it. - The GIC code has moved into the arm directory. - To make review easier (as requested), libfdt support is now added before the main ARM commit, which now uses the FDT immediately rather than adding support in later commits. - I also re-enabled test_xenbus. The old code said "Xenbus tests disabled, because of a Xend bug". Since xend doesn't exist any longer, we can enable these again. This patch roll is also available here: https://github.com/talex5/xen/commits/sent-Jun-26 Please include Karim in any reply as I am not the author of much of this code.
