    Pull ARM updates from Russell King:
     "Included in this update:
    
       - Florian Fainelli noticed that userspace segfaults caused by the
         lack of kernel-userspace helpers was hard to diagnose; we now issue
         a warning when userspace tries to use the helpers but the kernel
         has them disabled.
    
       - Ben Dooks wants compatibility for the old ATAG serial number with
         DT systems.
    
       - Some cleanup of assembly by Nicolas Pitre.
    
       - User accessors optimisation from Vincent Whitchurch.
    
       - More robust kdump on SMP systems from Yufen Wang.
    
       - Sebastian Andrzej Siewior noticed problems with the SMP "boot_lock"
         on RT kernels, and so we convert the Versatile series of platforms
         to use a raw spinlock instead, consolidating the Versatile
         implementation. We entirely remove the boot_lock on OMAP systems,
         where it's unnecessary. Further patches for other systems will be
         submitted for the following merge window.
    
       - Start switching old StrongARM-11x0 systems to use gpiolib rather
         than their private GPIO implementation - mostly PCMCIA bits.
    
       - ARM Kconfig cleanups.
    
       - Cleanup a mostly harmless mistake in the recent Spectre patch in
         4.20 (which had the effect that data that can be placed into the
         init sections was incorrectly always placed in the rodata section)"
