memblock_reserve gets physical address rather than a pfn.
If I read arch/hexagon/include/asm/mem-layout.h correctly, the PHYS_OFFSET *is* the physical address of the RAM and ARCH_PFN_OFFSET is the first pfn:
#define PHYS_PFN_OFFSET (PHYS_OFFSET >> PAGE_SHIFT) #define ARCH_PFN_OFFSET PHYS_PFN_OFFSET
Did I miss something?
