[Qemu-devel] [PATCH 01/15] target-arm: Fix CP15 based WFI

[Peter Maydell]

From: Paul Brook <address@hidden>

The coprocessor register rework broke cp15 based WFI instructions.
We incorrectly fall through the normal register write case, which
incorrectly adds a forced block termination.  We've already done
a special version of this (DISAS_WFI), so return immediately.
