[ Upstream commit b16f3299ae1aa3c327e1fb742d0379ae4d6e86f2 ]
Building on ARCH=arc causes a "redefined" warning, so rename this driver's CACHE_LINE_MASK to avoid the warning.
../drivers/net/ethernet/hisilicon/hip04_eth.c:134: warning: "CACHE_LINE_MASK" redefined 134 | #define CACHE_LINE_MASK 0x3F In file included from ../include/linux/cache.h:6, from ../include/linux/printk.h:9, from ../include/linux/kernel.h:19, from ../include/linux/list.h:9, from ../include/linux/module.h:12, from ../drivers/net/ethernet/hisilicon/hip04_eth.c:7: ../arch/arc/include/asm/cache.h:17: note: this is the location of the previous definition 17 | #define CACHE_LINE_MASK (~(L1_CACHE_BYTES - 1))
