Subject: [PATCH 0/5] x86/ftrace: Cure boot time W+X mapping

Hi,

These few patches re-work and re-order boot things enough to avoid ftrace
creating boot time W+X maps.

The patches compile and boot for the one config I tested things on (with
ftrace=function enabled; *slooooow*).

I've pushed them out for the robots to have a go at here:
