I downloaded Buidroot and buil QEMU x86_64 environment with kernel 4.9 I applied my patch to mmap (added MAP_DENYWRITE for shared libraries) before building kernel.

Did you test to make sure that it doesn't apply that flag to mmap for things other than shared libraries? How do you identify that it's a shared library and not something else?
