[PATCH 14/17] Kbuild, lto: Add Link Time Optimization support

2014-02-08 Thread Andi Kleen
With LTO gcc will do whole program optimizations for the whole kernel and each module. This increases compile time, but can generate faster and smaller code and allows the compiler to do global checking. LTO allows gcc to inline functions between different files and do various other optimization
