ARM1176 CPUs have TrustZone support and can use the Vector Base
Address Register, but currently, qemu only adds VBAR support to ARMv7
CPUs. Fix this by adding a new feature ARM_FEATURE_VBAR which can used
for ARMv7 and ARM1176 CPUs.
The VBAR feature is always set for ARMv7 because some legacy boards
require it even if this is not architecturally correct.

The GICv3 requires that we only signal Pending interrupts to
the CPU. This category does not include Pending+Active interrupts,
which means we need to check whether the interrupt is Active in
the gicr_int_pending() and gicd_int_pending() functions.
Interrupts are rarely in the Active+Pending state, but KVM
uses this as part of its handling of the virtual timer, so
this bug was causing KVM to go into an infinite loop of
taking the vtimer interrupt when the guest first triggered it.

In the ARMCPRegInfo definitions for the GICv3 CPU interface
registers, we were trying to use .fieldoffset to specify
the locations of data fields within the GICv3CPUState struct.
This is completely broken, because .fieldoffset is for offsets
into the CPUARMState struct. We didn't notice because we
were only using this for reads to BPR0, AP0R<n>, IGRPEN0
and CTLR_EL3, and Linux doesn't use these registers.
Replace the .fieldoffset uses with explicit read functions.

The value of the MVFR1 (Media and VFP Feature Register 1) register for
the Cortex-A8 appears to be incorrect (according to the TRM, DDI0344K),
with the "full denormal arithmetic" and "propagation of NaN" fields
holding both 0 instead of both 1.
I had a go tracing the history of the use of this value, and it seems
it's always just been wrong in QEMU: maybe it was derived from early
documentation, or guessed based on the use of a "VFP Lite" implementation
in the Cortex-A8.
Depending on the startup/early-boot code in use, this can manifest as
failure to perform denormal arithmetic properly: in our case, selecting
a Cortex-A8 CPU when using QEMU as an instruction-set simulator for
bare-metal GCC testing caused tests using denormal arithmetic to
fail. Problems might be masked (or not occur) when using a full OS kernel
with suitable trap handlers (I'm not sure).

This patch adds checks when restoring from migration to avoid divide by

The new paging more is extension of IA32e mode with more additional page
table level.

physical address space (4PB).
The structure of new page table level is identical to pml4.
The feature is enumerated with CPUID.(EAX=07H, ECX=0):ECX[bit 16].
CR4.LA57[bit 12] need to be set when pageing enables to activate 5-level

The patch is to fix the confusing assert fail message caused by
un-initialized device structure (from bite sized tasks).
The bug can be reproduced by
./qemu-system-x86_64 -nographic -device cfi.pflash01
The CFI hardware is dynamically loaded by QOM realizing mechanism,
however the realizing function in pflash_cfi01_realize function
requires the device being initialized manually before calling, like
./qemu-system-x86_64 -nographic
-device cfi.pflash01,num-blocks=1024,sector-length=4096,name=testcard
Once the initializing parameters are left off in the command, it will
leave the device structure not initialized, which makes
pflash_cfi01_realize try to realize a zero-volume card, causing
/mnt/EXT_volume/projects/qemu/qemu-dev/exec.c:1378:
find_ram_offset: Assertion `size != 0\' failed.
Through my test, at least the flash device's block-number, sector-length
and its name is needed for pflash_cfi01_realize to behave correctly. So
I think the new asserts are needed to hint the QEMU user to specify
the device's parameters correctly.
