Hi Richard,

Thanks for the report. v10 was based on v7.2-rc2 (8cdeaa50eae8), where 
patch 5 includes <cxlpci.h>. On that base, drivers/cxl/cxlpci.h provides 
the complete enum cxl_regloc_type definition and CXL_REGLOC_RBI_COMPONENT.

The definitions moved to <cxl/pci.h> in the newer tree as part of the 
CXL Type 2 enabling work. v11 is rebased onto v7.3-rc1 and uses the new 
public header.

If this failure reproduces on the declared v10 base, please let me know. 
Otherwise, I guess this resulted from applying v10 to a newer base after 
the header relocation?
But anyways, in v11, patches should use the new base and compile 
individually.
