Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Instead of setting CPUState::halted to 1 in s390_cpu_initfn(), use the

There are other platforms which also have CPUs that start powered off, so
generalize the start-powered-off property so that it can be used by them.
Note that ARMv7MState also has a property of the same name but this patch
doesn't change it because that class isn't a subclass of CPUState so it
wouldn't be a trivial change.
This change should not cause any change in behavior.

There are several problems here that can result in soft lockup,
depending on exactly where an interrupt or exception is delivered:
Include BIMM_FLAG in IFLAGS_TB_MASK, since it needs to follow D_FLAG.
Ensure that iflags is 0 when entering an interrupt/exception handler.
Add mb_cpu_synchronize_from_tb to restore iflags from tb->flags.
The change to t_sync_flags is cosmetic, but makes the code clearer.
This fixes the reported regression in acceptance/replay_kernel.py.

The current qemu hppa emulation emulates a PA1.1 CPU, which can only execute
the 32-bit instruction set. For unknown 64-bit instructions, a instruction trap
is sent to the virtual CPU.
This behaviour is correct in the sense that we emulate what the PA1.1
specification says.
But when trying to boot older Linux installation images, e.g.
ftp://parisc.parisc-linux.org/debian-cd/debian-5.0/lenny-5.0.10-hppa-iso-cd/cdimage.debian.org/debian-5010-hppa-netinst.iso
one finds that qemu fails to boot those images.
The problem is, that in the Linux kernel (e.g. 2.6.26) of those old images
64-bit instructions were used by mistake in the fault handlers. The relevant
instructions (the ",*" indicates that it's a 64-bit instruction) I see are:
0: 09 3e 04 29 sub,* sp,r9,r9
0: 08 3d 06 3d add,* ret1,r1,ret1
0: 0a 09 02 61 or,* r9,r16,r1
0: 0a ba 00 3a andcm,* r26,r21,r26
0: 08 33 02 33 and,* r19,r1,r19
The interesting part is, that real physical 32-bit machines (like the 700/64
and B160L - which is the one we emulate) do boot those images and thus seem to
simply ignore the 64-bit flag on those instructions.
The patch below modifies the qemu instruction decoder to ignore the 64-bit flag
too - which is what real 32-bit hardware seems to do. With this modification
qemu now successfully boots those older images too.
I suggest to apply the patch below - even if it does not reflect what the SPEC
says. Instead it increases the compatibility to really existing hardware and
seem to not create problems if we add real PA2.0 support anytime later.

Until now the TLB size was fixed at 256 entries. To allow operating
systems to utilize more TLB entries in the future, we need to tell
firmware how many TLB entries we actually support in the emulation.
Firmware then reports this to the operating system via the
PDC_CACHE_INFO call.
This patch simply does the preparation to allow more TLB entries.

Currently we have a RXCPU typedef and a RXCPU type checking
macro, but OBJECT_DECLARE* would transform the RXCPU macro into a
function, and the function name would conflict with the typedef
name.
Rename the RXCPU* QOM type check macros to RX_CPU*, so we will
avoid the conflict and make the macro names consistent with the
TYPE_RX_CPU constant name.
This will make future conversion to OBJECT_DECLARE* easier.

There's a typo in the type name of AARCH64_CPU_GET_CLASS. This
was never detected because the macro is not used by any code.

Some QOM macros were using a X86_IOMMU_DEVICE prefix, and others
were using a X86_IOMMU prefix. Rename all of them to use the
same X86_IOMMU_DEVICE prefix.
This will make future conversion to OBJECT_DECLARE* easier.

User-space programs cannot use the 64-bit lwea/swea instructions.
We can improve code generation and runtime by restricting the
user-only address space to 32-bit.

Do not initialize cpu_R[0], as this should be totally unused.
The cpu_for_read and cpu_for_write functions use a local temp.
