Hi Linus,
besides the kbuild branch, here is the LTO build support by Andi. It is
a separate branch, because it depends on other patches by Andi which
were merged through other trees. The link-time-optimization build is an
experimental feature, so there one kconfig option to enable it and
another kconfig option to disable it (behind a door with a sign "Beware
of the Leopard"...), so that it is not enabled by
allmodconfig/allyesconfig.
Thanks,
Michal
