Subject: powerpc32 boot crash in 5.1-rc1

While 5.0.0 worked fine on my PowerMac G4, 5.0 + git (unknown rev as of Mar 13),
5.0.0-11520-gf261c4e and todays git all fail to boot.

The problem seems to be in page fault handler in load_elf_binary() of init process.

Two different screenshots are at http://kodu.ut.ee/~mroos/powerpc-boot-hang-1.jpg and

The patch at https://patchwork.ozlabs.org/patch/1053385/ should fix it
