Subject: Add "x86/build: Build compressed x86 kernels as PIE" to the v4.4.y
 stable tree?

Hi,

It took me quite some time to get v4.4.24 to successfully boot (this
was a 32 bits build on Fedora 24). Especially annoying was that it
failed silently on real hardware. Only after messing around with Qemu
it became clear what might be going on. 

It turned out Fedora 24 ships binutils-2.26, and using that version of
binutils apparently requires commit 6d92bc9d483a ("x86/build: Build
compressed x86 kernels as PIE"). Does is makes sense to add that commit
to the v4.4.y stable tree?

Thanks,

Paul Bolle
