This patch causes warnings on mips:
linux/init/main.c: In function 'start_kernel':
linux/init/main.c:633: warning: passing argument 1 of 'virt_to_phys' makes pointer from integer without a cast
linux/init/main.c:636: warning: passing argument 1 of 'virt_to_phys' makes pointer from integer without a cast
Because an argument of mips virt_to_phys() is an pointer and
initrd_start is unsigned long. It seems most (all?) arch's
virt_to_phys() casts its argument to unsigned long internally. Should
mips follow?
