Not all 32-bit configurations can provide cmpxchg64(). i40e's use of cmpxchg64() appears to be fixed by:
b74f571f59a8 i40e/i40evf: organize and re-number feature flags b48be9978e4b i40e: fix flags declaration
So without those patches, are any specific arches/configs broken for 4.14?
32-bit parisc is.
Ok, but that's a horrid hack on the i40e driver, it just happens to move the bitfield to a 32bit variable. Can't we just provide a "real" cmpxchg64() for 32-bit parisc?
No. There is a generic implementation of cmpxchg64() but it is only suitable for non-SMP configurations.
Or mark this driver as not buildable on that platform?
I suggested adding a 'depends 64BIT' but got no response.
Ben.
I doubt anyone is doing 40gb networking on parisc :)
thanks,
