3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <a...@arndb.de>
commit dd94d3558947756b102b1487911acd925224a38c upstream.
Commit b713aa0b15 "ARM: fix asm/memory.h build error" broke some
configurations on mach-realview with sparsemem enabled, which
is missing a definition of PHYS_OFFSET:
arch/arm/include/asm/memory.h:268:42: error: 'PHYS_OFFSET' undeclared (first
use in this function)
#define PHYS_PFN_OFFSET ((unsigned long)(PHYS_OFFSET >> PAGE_SHIFT))
arch/arm/include/asm/dma-mapping.h:104:9: note: in expansion of macro
'PHYS_PFN_OFFSET'
return PHYS_PFN_OFFSET + dma_to_pfn(dev, *dev->dma_mask);
An easy workaround is for realview to define PHYS_OFFSET itself,
in the same way we define it for platforms that don't have a private
__virt_to_phys function.
