for KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION attribute, the attribute
data pointed to by kvm_device_attr.addr is a OR of the
redistributor region address and other fields such as the index
of the redistributor region and the number of redistributors the
region can contain.
The existing machine init done notifier framework sets the address
field to the actual address of the device and does not allow to OR
this value with other fields.
This patch extends the KVMDevice struct with a new kda_addr_ormask
member. Its value is passed at registration time and OR'ed with the
resolved address on kvm_arm_set_device_addr().

When either GICD_IPRIORITYR or GICR_IPRIORITYR is read as a 32-bit
register, the post left-shift operator in the for loop causes an
extra shift after the least significant byte has been placed.
The 32-bit value actually returned is therefore the expected value
shifted left by 8 bits.

The Cortex-M CPU and its NVIC are two intimately intertwined parts of
the same hardware; it is not possible to use one without the other.
Unfortunately a lot of our board models don't do any sanity checking
on the CPU type the user asks for, so a command line like
qemu-system-arm -M versatilepb -cpu cortex-m3
will create an M3 without an NVIC, and coredump immediately.
In the other direction, trying a non-M-profile CPU in an M-profile
board won't blow up, but doesn't do anything useful either:
qemu-system-arm -M lm3s6965evb -cpu arm926
Add some checking in the NVIC and CPU realize functions that the
user isn't trying to use an NVIC without an M-profile CPU or
an M-profile CPU without an NVIC, so we can produce a helpful
error message rather than a core dump.

If the GIC has the security extension support enabled, then a
non-secure access to ICC_PMR must take account of the non-secure
view of interrupt priorities, where real priorities 0x00..0x7f
are secure-only and not visible to the non-secure guest, and
priorities 0x80..0xff are shown to the guest as if they were
0x00..0xff. We had the logic here wrong:
* on reads, the priority is in the secure range if bit 7
is clear, not if it is set
* on writes, we want to set bit 7, not mask everything else
Our ICC_RPR read code had the same error as ICC_PMR.

Presently s390x is the only architecture not exposing specific
CPU information via QMP query-cpus. Upstream discussion has shown
that it could make sense to report the architecture specific CPU
state, e.g. to detect that a CPU has been stopped.
With this change the output of query-cpus will look like this on
s390:
[
{"arch": "s390", "current": true,
"props": {"core-id": 0}, "cpu-state": "operating", "CPU": 0,
"qom_path": "/machine/unattached/device[0]",

"qom_path": "/machine/unattached/device[1]",

]
This change doesn't add the s390-specific data to HMP 'info cpus'.
A follow-on patch will remove all architecture specific information
from there.

NVIC_IABR<n> -- in all these cases we were missing the "* 8"

M profile cores have a similar setup for cache ID registers
to A profile:
* Cache Level ID Register (CLIDR) is a fixed value
* Cache Type Register (CTR) is a fixed value
* Cache Size ID Registers (CCSIDR) are a bank of registers;
which one you see is selected by the Cache Size Selection
Register (CSSELR)
The only difference is that they're in the NVIC memory mapped
register space rather than being coprocessor registers.
Implement the M profile view of them.
Since neither Cortex-M3 nor Cortex-M4 implement caches,
we don't need to update their init functions and can leave
the ctr/clidr/ccsidr[] fields in their ARMCPU structs at zero.
Newer cores (like the Cortex-M33) will want to be able to
set these ID registers to non-zero values, though.

This cleanup makes the number of objects depending on qapi/error.h
drop from 1910 (out of 4743) to 1612 in my "build everything" tree.
While there, separate #include from file comment with a blank line,
and drop a useless comment on why qemu/osdep.h is included first.

Currently armv7m_nvic_acknowledge_irq() does three things:
* make the current highest priority pending interrupt active
* return a bool indicating whether that interrupt is targeting
Secure or NonSecure state
* implicitly tell the caller which is the highest priority
pending interrupt by setting env->v7m.exception
We need to split these jobs, because v7m_exception_taken()
needs to know whether the pending interrupt targets Secure so
it can choose to stack callee-saves registers or not, but it
must not make the interrupt active until after it has done
that stacking, in case the stacking causes a derived exception.
Similarly, it needs to know the number of the pending interrupt
so it can read the correct vector table entry before the
interrupt is made active, because vector table reads might
also cause a derived exception.
Create a new armv7m_nvic_get_pending_irq_info() function which simply
returns information about the highest priority pending interrupt, and
use it to rearrange the v7m_exception_taken() code so we don't
acknowledge the exception until we've done all the things which could
possibly cause a derived exception.

In order to support derived exceptions (exceptions generated in
the course of trying to take an exception), we need to be able
to handle prioritizing whether to take the original exception
or the derived exception.
We do this by introducing a new function
armv7m_nvic_set_pending_derived() which the exception-taking code in
helper.c will call when a derived exception occurs. Derived
exceptions are dealt with mostly like normal pending exceptions, so
we share the implementation with the armv7m_nvic_set_pending()
function.
Note that the way we structure this is significantly different
from the v8M Arm ARM pseudocode: that does all the prioritization
logic in the DerivedLateArrival() function, whereas we choose to
let the existing "identify highest priority exception" logic
do the prioritization for us. The effect is the same, though.

Let the flic device handle it internally. This will allow us to later
on store floating interrupts in the flic for the TCG case.
This now also simplifies kvm.c. All that's left is the fallback
interface for floating interrupts, which is now triggered directly via
the flic in case anything goes wrong.

When C_CTRL.CBPR is 1, the Non-Secure view of C_BPR is altered:
- A Non-Secure read of C_BPR should return the BPR value plus 1,
saturated to 7,
- A Non-Secure write should be ignored.
