Because an argument of mips virt_to_phys() is an pointer and
initrd_start is unsigned long. It seems most (all?) archs
virt_to_phys() casts its argument to unsigned long internally. Should
mips follow?
Alternatively, as initrd_start is really a virtual kernel address,
perhaps it should be changed from unsigned long to void * instead?
Its cast to `void * in several place. arch/xtensa/kernel/setup.c even
has `extern void *initrd_start to fool around this?
I agree it would make code cleaner, but the conversion might be
somewhat hard.
If we converted initrd_start (and initrd_end) to void *, we should
also convert INITRD_START, free_initrd_mem(), some other arch specific
local/global variables and printk format strings. Also code like
"initrd_start & PAGE_MASK" should be changed too...
Is it worth to do?
