[Qemu-devel] [PATCH v1 01/10] target-arm: Log the target EL when taking exceptions

["Edgar E. Iglesias" <edgar.iglesias@gmail.com>]

From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>

Log the target EL when taking exceptions. This is useful when
debugging guest SW or QEMU itself while transitioning through
the various ELs.
