Hi Vincenzo,

In the end I concluded that all the errors seen here depend on the fact that I
tested my vdso implementation on MIPS32el only (as stated in the cover letter)
and that when I tried to compile a 32BIT binary on a 64BIT configuration I did
it wrongly for two reasons, for N32 and O32 binaries:
 - we need to undefine CONFIG_64BIT and define CONFIG_32BIT
 - we need to define CONFIG_GENERIC_ATOMIC64

I have a fix for this (patch in attachment), but I do not have the hardware to
test it. If you could provide some feedback would be appreciated (really want to
see MIPS merged with the other archs in 5.3 :) ).
Thanks for the quick turnaround on your patch!

I'm certainly willing to test it, but in a few hours I'll be spending
the bulk of a day on airplanes[1] so it might take a few days until I
get to it.

Thanks,
    Paul

    son around :)
