[Thomas Gleixner]

Linus,

please pull the latest x86-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git 
x86-urgent-for-linus

Two small fixlets for x86:

 - Prevent a KASAN false positive in thread_saved_pc()

 - Fix a 32-bit truncation problem in the x86 numa code

Thanks,

        tglx
