Hi all,

As discussed in https://gcc.gnu.org/ml/gcc/2014-09/msg00234.html , this patchset backports mainline patches necessary for Kernel ASan in GCC 4.9 (gcc-4_9-branch). The patcheset consists of
* Asan headers installation (1 patch)
* __asan_loadN/__asan_storeN support (3 patches)
* instrumentation with calls support (1 patch)
* optimization of strlen instrumentation (1 patch)
* Kasan support (3 patches)
* move inlining to sanopt (1 patches)
* bugfixes (7 patches)

To my knowledge it does not contain any changes that would influence ABI of generated code.

The code was bootstrapped and regtested on x64 (I only tested the net result, not each patch in isolation).

-Y
