commit 91a62bac46aaa40d6fc94fb95f01119ea9a561c2
Author: Anton Blanchard <anton@samba.org>
Date:   Sat Oct 1 20:41:56 2016 +1000

    powerpc/pseries: Use H_CLEAR_HPT to clear MMU hash table during kexec
    
    An hcall was recently added that does exactly what we need during kexec
    - it clears the entire MMU hash table, ignoring any VRMA mappings.
    
    Try it and fall back to the old method if we get a failure.
    
    On a POWER8 box with 5TB of memory, this reduces the time it takes to
    kexec a new kernel from from 4 minutes to 1 minute.
