Subject: powerpc: fix io.h build warning with CONFIG_PHYS_64BIT
X-Git-Tag: v2009.01-rc1~3^2~1

powerpc: fix io.h build warning with CONFIG_PHYS_64BIT

Casting a pointer to a phys_addr_t when it's an unsigned long long
on a 32-bit system without first casting to a non-pointer type
generates a compiler warning. Fix this.
