attaching updated patch which uses ioremap() instead of acpi_get_table. Tested it across some S3 iterations on xen tip from today and Lenovo T520 and seems to work well (although there are some unrelated scheduler issues on resume which we have patched separately on our end; intending to submit these patches as well later on). Doesn't work on older trees from before your "implement vmap()" commit. You mentioned that this would be fixable on older trees via adding the acpi table range to the 1:1 mapping - how would one go about this as I'm not sure where is the relevant code located?
