Before (in v5), the translation table was in the .data section and therefore could end up in a different memory section to the boot code. By moving it to 0x4000, I simplified all that logic because we now know that the translation table and the boot code are both in the same 1MB memory section, which avoids any problem with the old and new mappings overlapping. -- Dr Thomas Leonard http://0install.net/ GPG: 9242 9807 C985 3C07 44A6 8B9A AE07 8280 59A5 3CC1 GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
