Add explicit casting to unsigned long to the __va() parameter
Why is this needed?
To make it consitent with other architecures and asm-generic :)
But more importantly, __memblock_free_late() passes u64 to page_to_pfn().
Why does memblock work in terms of u64 instead of phys_addr_t?
Yes, phys_addr_t was exactly that came to my mind as well. Casting
physical address to unsigned long just screams for potential problems.
