Merge tag 'sh-for-v7.1-tag2' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh fix from John Paul Adrian Glaubitz:
 "The ZERO_PAGE consolidation in v7.1, introduced a regression on sh
  which made these systems unbootable.

  The problem was that on sh, the initial boot parameters were
  previously referenced as an array and after 6215d9f447 ("arch, mm:
  consolidate empty_zero_page"), they were referenced as a pointer which
  caused wrong code generation and boot hang.

  This changes the declaration back to being an array which fixes the
  boot hang"
