This follows the previous patches, where support for migrating the
entire MAC registers' array, and some new MAC registers were introduced.
This patch introduces the e1000-specific boolean parameter
"extra_mac_registers", which is on by default. Setting it to off will
enable migration to older versions of QEMU, but will disable the read
and write access to the new registers, that were introduced since adding
the ability to migrate the entire MAC array.
Example for usage to enable backward compatibility and to disable the
new MAC registers:
qemu-system-x86_64 -device e1000,extra_mac_registers=off,... ...
As mentioned above, the default value is "on".

Previously, these 64-bit registers did not stick at their maximal
values when (and if) they reached them, as they should do, according to
the specs.
This patch introduces a function that takes care of such registers,
avoiding code duplication, making the relevant parts more compatible
with the QEMU coding style, while ensuring that in the unlikely case
of reaching the maximal value, the counter will stick there, as it

These registers appear in Intel's specs, but were not implemented.
These registers are now implemented trivially, i.e. they are initiated
with zero values, and if they are RW, they can be written or read by the
driver, or read only if they are R (essentially retaining their zero
values). For these registers no other procedures are performed.
For the trivially implemented Diagnostic registers, a debug warning is
produced on read/write attempts.
PLEASE NOTE: these registers will not be active, nor will migrate, until
a compatibility flag will be set (in a later patch in this series).
The registers implemented here are:
Transmit:
RW: AIT

RW: WUC WUS IPAV IP6AT* IP4AT* FFLT* WUPM* FFMT* FFVT*

The array of uint8_t's which is introduced here, contains access metadata
about the MAC registers: if a register is accessible, but partly implemented,
or if a register requires a certain compatibility flag in order to be
accessed. Currently, 6 hypothetical flags are supported (3 exist for e1000
so far) but in the future, if more than 6 flags will be needed, the datatype
of this array can simply be swapped for a larger one.
This patch is intended to solve the following current problems:
1) In a scenario of migration between different versions of QEMU, which
differ by the MAC registers implemented in them, some registers need not to
be active if a compatibility flag is set, in order to preserve the machine's
state perfectly for the older version. Checking this for each register
individually, would create a lot of clutter in the code.
2) Some registers are (or may be) only partly implemented (e.g.
placeholders that allow reading and writing, but lack other functions).
In such cases it is better to print a debug warning on read/write attempts.
As above, dealing with this functionality on a per-register level, would
require longer and more messy code.

This patch makes the migration of the entire array of MAC registers
possible during live migration. The entire array is just 128 KB long, so
practically no penalty should be felt when transmitting it, additionally
to the previously transmitted individual registers. The advantage here is
eliminating the need to introduce new vmstate subsections in the future,
when additional MAC registers will be implemented.
Backward compatibility is preserved by introducing a e1000-specific
boolean parameter (in a later patch), which will be on by default.
Setting it to off would enable migration to older versions of QEMU.
Additionally, this parameter will be used to control the access to the
extra MAC registers in the future.

At the moment get_monitor_def() returns only registers from statically
defined monitor_defs array. However there is a lot of BOOK3S SPRs
which are not in the list and cannot be printed from the monitor.
This adds a new target platform hook - target_get_monitor_def().
The hook is called if a register was not found in the static
array returned by the target_monitor_defs() hook.
The hook is only defined for POWERPC, it returns registered
SPRs and fails on unregistered ones providing the user with information
on what is actually supported on the running CPU. The register value is
saved as uint64_t as it is the biggest supported register size;
target_ulong cannot be used because of the stub - it is in a "common"
code and cannot include "cpu.h", etc; this is also why the hook prototype
is redefined in the stub instead of being included from some header.
This replaces static descriptors for GPRs, FPRs, SRs with a helper which
looks for a value in a corresponding array in the CPUPPCState.
The immediate effect is that all 32 SRs can be printed now (instead of 16);
later this can be reused for VSX or TM registers.
This replaces callbacks for MSR and XER with static descriptors in
monitor_defs as they are stored in CPUPPCState.
While we are here, this adds "cr" as a synonym of "ccr".

According to the ISA setting the Rc bit on mtspr is undefined behavior.
Real 750 hardware simply ignores the bit and doesn't touch cr0 though.
Unfortunately, Mac OS 9 relies on this fact and executes a few mtspr

So let's handle the bit the same way hardware does and ignore it.

The non-ccw machine for s390 (s390-virtio) is not very well maintained
and caused several issues in the past:
- aliases like virtio-blk did not work for s390
- virtio refactoring failed due to long standing bugs (e.g.see
commit cb927b8a "s390-virtio: Accommodate guests using virtqueues too early")
- some features like memory hotplug will cause trouble due to virtio storage
being above guest memory
- the boot loader bios no longer seems to work. the source code of that
loader is also no longer maintained
2.4 changed the default to the ccw machine, let's deprecate the old
machine for 2.5.

Let's move the qom definitions of the ipl device into ipl.h, replace
"s390-ipl" by a proper type define, turn it into a TYPE_DEVICE
and remove the unneeded class definition.

For TYPE_DEVICE, the dc->reset() function is not called on system resets
yet. Until that is changed, we have to manually register a reset handler.
Let's provide qdev_reset_all_fn(), that can directly be used - just like
the reset handler that is already available for qbus.

Because of El Torito spec flaw boot image size needs to be verified.
Boot catalog entry size field has 16-bit width, and specifies size
in 512-byte units.
Thus, boot image size cannot exceed 32M.
We actually search for the file to get the file size.
This is done by scanning the ISO directory tree for the ISO block number
and reading the file size from the directory entry.

Boot entry is considered compatible if boot image is Linux kernel
with matching S390 Linux magic string.
Empty boot images with sector_count == 0 are considered broken.

This patch enables boot from media formatted according to
ISO-9660 and El Torito bootable CD specification.
We try to boot from device as ISO-9660 media when SCSI IPL failed.
The first boot catalog entry with bootable flag is used.
ISO-9660 media with default 2048-bytes sector size only is supported.

Let's always adjust the sector number to be read using the current
virtio block size value.
This prepares for the implementation of IPL from ISO-9660 media.

By replacing memory_region_init_ram with memory_region_allocate_system_memory
we gain goodies like mem-path backends. This will allow us to use hugetlbfs
once the kernel supports it.

On s390x, each pci device has its own iommu, which is only properly
setup in qemu once the mpcifc instruction used to register the
translation table has been intercepted. Therefore, for a pci device that
is not configured or has not been initialized, proper translation is
neither required nor possible. Moreover, we may not have a host bridge
device ready yet.
This was exposed by a recent vfio change that triggers iommu translation
during the initialization of the vfio pci device. Let's do an early exit
in that case.
