From: Amos Waterland This function expects an unsigned 32-bit type as its third argument: static u32 pci_size(u32 base, u32 maxbase, u32 mask) However, given these definitions: #define PCI_BASE_ADDRESS_MEM_MASK (~0x0fUL) #define PCI_ROM_ADDRESS_MASK (~0x7ffUL) these two calls in drivers/pci/probe.c are problematic for architectures for which a UL is not equivalent to a u32: sz = pci_size(l, sz, PCI_BASE_ADDRESS_MEM_MASK); sz = pci_size(l, sz, PCI_ROM_ADDRESS_MASK); Hence the below compile warning when building for ARCH=ppc64: drivers/pci/probe.c: In function `pci_read_bases': /.../probe.c:168: warning: large integer implicitly truncated to unsigned type /.../probe.c:218: warning: large integer implicitly truncated to unsigned type Here is a simple fix.
