Re: [PATCH v2 0/4] Disable compat cruft on ppc64le v2

Michal Suchanek's on August 28, 2019 8:30 pm:

With endian switch disabled by default the ppc64le compat supports
ppc32le only which is something next to nobody has binaries for.

Less code means less bugs so drop the compat stuff.

Interesting patches, thanks for looking into it. I don't know much
about compat and wrong endian userspaces. I think sys_switch_endian
is enabled though, it's just a strange fast endian swap thing that
has been disabled by default.

The first patches look pretty good. Maybe for the last one it could
become a selectable option?

I am not particularly sure about the best way to resolve the llseek
situation. I don't see anything in the syscal tables making it
32bit-only so I suppose it should be available on 64bit as well.

It's for 32-bit userspace only. Can we just get rid of it, or is
there some old broken 64-bit BE userspace that tries to call it?

Thanks,
Nick
