urrently I have to revert 2 patches to get anywhere near a build
and work around 50644. 32bit builds don't work at all because of
the tree-nrv problem.
50620 causes incredly slow builds because partitioning has to be disabled

I've no problems building the kernel with LTO at the moment,
but I use no modules and a fairly minimal config.
I've seen a few strange segfaults while testing the LTO kernel however.
For example:
screen[1608]: segfault at 7fff42d73e98 ip 000000000040600a sp 00007fff42d73ea0
error 6 in screen[400000+55000]
or
zsh[1643]: segfault at 7f7980eb4000 ip 00007f7981db6cb0 sp 00007fff1f4b6dd8
error 7 in libc-2.14.90.so[7f7981d34000+15f000]
But I'm not 100% sure, that they're really LTO related.

No. It turned out that the segfaults above weren't related to LTO kernels.
