ARM: 8676/1: NOMMU: provide pgprot_device() macro
NOMMU build leads to the following error: CC drivers/pci/mmap.o drivers/pci/mmap.c: In function 'pci_mmap_resource_range': drivers/pci/mmap.c:60:3: error: implicit declaration of function 'pgprot_device' [-Werror=implicit-function-declaration] vma->vm_page_prot = pgprot_device(vma->vm_page_prot); ^ cc1: some warnings being treated as errors scripts/Makefile.build:302: recipe for target 'drivers/pci/mmap.o' failed make[2]: *** [drivers/pci/mmap.o] Error 1 scripts/Makefile.build:561: recipe for target 'drivers/pci' failed make[1]: *** [drivers/pci] Error 2 Makefile:1016: recipe for target 'drivers' failed make: *** [drivers] Error 2 Fix it with support of pgprot_device() macro for NOMMU.
