All other tree specific definition will be left for intact. Maybe they can be renamed. PCIBIOS* is an x86 concept as defined by the PCI spec. The returned error codes of PCIBIOS* are positive values and this introduces some complexities which other archs need not incur. PLAN: 1. [PATCH v0 1-36] Replace all PCIBIOS_SUCCESSFUL with 0 2a. Audit all functions returning PCIBIOS_* error values directly or indirectly and prevent possible bug coming in (2b) 2b. Make all functions returning PCIBIOS_* error values call pcibios_err_to_errno(). *This will change their behaviour, for good.* 3. Clone a pcibios_err_to_errno() into arch/x86/pci/pcbios.c as _v2. This handles the positive error codes directly and will not use any PCIBIOS* definitions. So calls to it have no outside dependence. 4. Make all x86 codes that needs to convert to -E* values call the cloned version - pcibios_err_to_errno_v2() 5. Assign PCIBIOS_* errors values directly to generic -E* errors 6. Refactor pcibios_err_to_errno() and mark it deprecated 7. Replace all calls to pcibios_err_to_errno() with the proper -E* value or 0. 8. Remove all PCIBIOS* definitions in include/linux/pci.h and pcibios_err_to_errno() too. 9. Redefine all PCIBIOS* definitions with original values inside arch/x86/pci/pcbios.c 10. Redefine pcibios_err_to_errno() inside arch/x86/pci/pcbios.c 11. Replace pcibios_err_to_errno_v2() calls with pcibios_err_to_errno() 12. Remove pcibios_err_to_errno_v2() Suggested-by: Bjorn Helgaas Suggested-by: Yicong Yang Signed-off-by: "Saheed O.
