x86/PCI: never allocate PCI MMIO resources below BIOS_END
> Agreed. The trickier part is handling any platform devices that request_resource against that space. But maybe we don't need to do anything special; just making sure we avoid it in the PCI "BIOS" code as Bjorn did may be sufficient. Why is that hard?

[PATCH 1/4] Add targets to use the Coccinelle checker
Four targets are added. Each one generates a different output kind: context, patch, org, report. Every SmPL file in 'scripts/smpl' is given to the spatch frontend (located in the 'scripts' directory), and applied to the entire source tree.
