Frans,
You put (do not remove anything) the statement:
if (is_ISA_range(phys_addr, last_addr))
return (__force void __iomem *)phys_to_virt(phys_addr);
around line 106 of arch/x86/mm/ioremap.c
just before the lines:
/*
* Don't allow anybody to remap normal RAM that we're using..
*/
pfn = phys_addr >> PAGE_SHIFT;
You can how the older code was altered here:
