This series fixes a couple more minor EL3 related missing parts,
and then turns on EL3 for AArch64 CPUs. The minor fixed things are:
* implement MDCR_EL3 and SDCR
* trap Secure EL1 accesses to SCR and MVBAR to EL3
* add EL3 support to the code that decides whether to generate
debug exceptions
The registers MVBAR and SCR should have the behaviour of trapping to
EL3 if accessed from Secure EL1, but we were incorrectly implementing
them to UNDEF (which would trap to EL1). Fix this by using the new
access_trap_aa32s_el1() access function.

Depending on what object a file descriptor refers to a different
type of IO channel will be needed - either a QIOChannelFile or
a QIOChannelSocket. Introduce a qio_channel_new_fd() method
which will return the appropriate channel implementation.

While there are more formats still missing blockdev-add support, I
personally felt like NBD really is one we do need, and also it was
pretty simple to do.
Therefore, I started with NBD. Maybe I'll follow up with other formats.

Implement saving and restoring to KVM state of the Processor ID (PRid)
CP0 register. This allows QEMU to control the PRid exposed to the guest
instead of using the default set by KVM.

Changes in v3:
- Fix big endian (the pointer passed
The DPRINTFs in cpu_mips_io_interrupts_pending() and kvm_arch_pre_run()
are particularly noisy during normal execution, and also not
particularly helpful. Remove them so that more important debug messages
can be more easily seen.

Hi all,
A while ago me and Alex [cc'ed] submitted a trivial patch related to
logging [1]. Since this patch set here moves the qemu-log.c under util/,
our patch will not apply any more. Should we rebase it and resend it
against current master?
Thanks a lot,

Don't claim error_report_err() always reports to stderr. It actually
reports to the current monitor when we have one.
Clarify intended use of error_abort and error_fatal.
