I pointed out that we should use the flags to determine formattingIt's 64-bit on sparc64 :-)
options, e.g. I/O space is only 16 bits on x86.
There's also the bit where we use a 32-bit resource_t on sparc32
but encode the top 4-bits of the 36 bit physical I/O address in
the resource flags member.
resource_t? I think all other platforms with 36-bit physical addresses went
Absolutely, this is what should happen.
I'll try to make this happen in 2.6.29, it's a moderately invasive
change because it effects how ioremap() and friends are implemented.
