    powerpc: Define and use PPC64_ELF_ABI_v2/v1 · f55d9665
    Michael Ellerman 提交于
    We're approaching 20 locations where we need to check for ELF ABI v2.
    That's fine, except the logic is a bit awkward, because we have to check
    that _CALL_ELF is defined and then what its value is.
    
    So check it once in asm/types.h and define PPC64_ELF_ABI_v2 when ELF ABI
    v2 is detected.
    
    We also have a few places where what we're really trying to check is
    that we are using the 64-bit v1 ABI, ie. function descriptors. So also
    add a #define for that, which simplifies several checks.
