[PATCH 00/26] Linux cleanups enabled by built-in system call tables

[Florian Weimer <fweimer at redhat dot com>]

This series cleans up various quirks in the Linux implementation related
to historic lack of system call numbers in several places.

It has been tested on aarch64-linux-gnu, i686-linux-gnu,
powerpc64le-linux-gnu, s390x-linux-gnu, x86_64-linux-gnu, and also built
with build-many-glibcs-py.

I did not touch the futex #ifdefs because they are going to change soon
enough.

Thanks,
Florian
