if one boots a kernel with LPAE enabled on a system not supporting LPAE,
it'll stop booting very early with the "well known message" :
Error: unrecognized/unsupported processor variant
This means it should be enabled only on SoC with LPAE support and afaik,
none of our armhf platforms have it.

hm. I thought it was already in 3.2 but looks like it was not. BPF JIT
on arm is limited to commit
ddecdfcea0ae891f782ae853771c867ab51024c2. Will look at that. There are
some kconfig fixes too but I'm not sure we need them.
