The following patch (not upstream yet): "x86/boot/e820: Remove spurious asm/e820/api.h inclusions"
Removed the (spurious) <asm/e820.h> include line from <asm/pgtable.h> to reduce header file dependencies - but a Xen header has (unintentionally) learned to rely on the indirect inclusion of <linux/device.h>. This resulted in the following (harmless) build warning: arch/x86/include/asm/xen/page.h:302:7: warning: 'struct device' declared inside parameter list Include <linux/device.h> explicitly. No change in functionality.
