Subject[PATCH 4/5] xen, x86/headers: Add <linux/device.h> dependency to <asm/xen/page.h>
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.
