Subject[PATCH] MIPS: Add KSEG*ADDR definitions to CONFIG_64BIT
Date
The patch adds KSEG0ADDR, KSEG1ADDR, KSEG2ADDR, KSEG3ADDR
definitions to CONFIG_64BIT ifdef. This fixes broken compilation:
CC drivers/watchdog/mtx-1_wdt.o
In file included from drivers/watchdog/mtx-1_wdt.c:44:
./arch/mips/include/asm/mach-au1x00/au1000.h: In function ‘alchemy_rdsys’:
./arch/mips/include/asm/mach-au1x00/au1000.h:603:36: error: implicit
declaration of function ‘KSEG1ADDR’; did you mean ‘CKSEG1ADDR’?
[-Werror=implicit-function-declaration]
