Arnd Bergmann b0a8d1a0b6 net: ezchip: fix address space confusion in nps_enet.c ... The nps_enet driver happily mixes virtual, physical and __iomem addresses, which are all different depending on the architecture and configuration. That causes a warning when building the code on ARM with LPAE mode enabled: drivers/net/ethernet/ezchip/nps_enet.c: In function 'nps_enet_send_frame': drivers/net/ethernet/ezchip/nps_enet.c:370:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] but will also fail to work for other reasons. In this patch, I'm trying to change the code to use only normal kernel pointers, which I assume is what the author actually meant: * For reading or writing a 32-bit word that may be unaligned when an SKB contains unaligned data, I'm using get_unaligned/put_unaligned() rather than memcpy_fromio/toio. * For converting a u8 pointer to a u32 pointer, I use a cast rather than the incorrect virt_to_phys. * For copying a couple of bytes from one place to another while respecting alignment, I use memcpy instead of memcpy_toio.
