Commit 594cc251fdd0 (user_access_begin does access_ok) made arch/sh stop booting on qemu.

That's what I bisected it to, anyway. Commit before that boots to a shell prompt under qemu-system-sh4 (built from today's git), after produces no console output (no boot messages, no nothin'). Rob # make ARCH=sh allnoconfig KCONFIG_ALLCONFIG=sh4.miniconf # make ARCH=sh -j $(nproc) # boot
