Ralf, Your commit 5bd35e65f101 ("MIPS: Replace MIPS-specific 64BIT_PHYS_ADDR with generic PHYS_ADDR_T_64BIT") is included in today's linux-next (ie, next-20141124). That commit does what it promises to do. There are a few references to 64BIT_PHYS_ADDR in linux-next: $ git grep -n 64BIT_PHYS_ADDR arch/mips/include/asm/pgtable-32.h:225:#endif /* defined(CONFIG_64BIT_PHYS_ADDR) && defined(CONFIG_CPU_MIPS32) */ drivers/dma/txx9dmac.c:79:#if defined(CONFIG_32BIT) && !defined(CONFIG_64BIT_PHYS_ADDR) drivers/dma/txx9dmac.h:70:#if defined(CONFIG_32BIT) && !defined(CONFIG_64BIT_PHYS_ADDR) drivers/dma/txx9dmac.h:204:#if defined(CONFIG_32BIT) && !defined(CONFIG_64BIT_PHYS_ADDR) drivers/pcmcia/Kconfig:150: select 64BIT_PHYS_ADDR drivers/pcmcia/Kconfig:161: select 64BIT_PHYS_ADDR I assume that patches to replace these references too are queued somewhere. Is that correct? Paul Bolle
