In the current git repository, on my amd64 machine I get the following warning 
on compile
drivers/pci/probe.c: In function `pci_read_bases':
drivers/pci/probe.c:166: warning: large integer implicitly truncated to 
unsigned type
drivers/pci/probe.c:216: warning: large integer implicitly truncated to 
unsigned type

I've tracked this down to pci_size, and two #define's in include/linux/pci.h

#define  PCI_BASE_ADDRESS_MEM_MASK      (~0x0fUL)
#define PCI_ROM_ADDRESS_MASK    (~0x7ffUL)

pci_size expects 3 u32 arguments,but from what I can tell, on 64 bit arch's the 
two above 
defines expand to 64bit values, and are truncated when being passed.

I'm not sure how to go about fixing this, if pci_size should accept a u64 or if 
the defines should
be changed. Is this bug dangerous? What should be done to fix it?
