Merge branch 'parisc-4.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc updates from Helge Deller:
 "Major changes include:

   - Full support of the firmware Page Deallocation Table with
     MADV_HWPOISON and MADV_SOFT_OFFLINE. A kernel thread scans
     regularily for new bad memory pages.

   - Full support for self-extracting kernel.

   - Added UBSAN support.

   - Lots of section mismatch fixes across all parisc drivers.

   - Added examples for %pF and %pS usage in printk-formats.txt"
