Thanks, Gabriel, and Damjan. It appears to me that the glibc getconf
program is using its own mechanisms for determining cache line size, rather
than using the information that the kernel has. That is my reading of the
glibc code, so I do not believe Damjan you will see any different behavior

Hi Gabriel,
I do not fully understand the mechanisms for all processors, and being that is
the case, perhaps you can add a lot of comments

Hi,
I am currently working on a patch to auto-detect the cache line size with a m4
macro in autoconf (https://gerrit.fd.io/r/#/c/4576/)
Part of it updates cache.h tests so that it raises an error if the cache line
length is undefined.
I am stuck at the libpneum compilation: it's a python mod
