'int access_type' and ACCESS_INT are unused, drop them.
Provide the mmu_idx argument to match other targets.
'int rw' is actually the MMUAccessType, rename it.

We have almost 400 lines of code full of /* TODO */ comments
which end calling gen_reserved_instruction().
As we are not going to implement them, and all the caller's
switch() default cases already call gen_reserved_instruction(),
we can remove this altogether.

Start it by moving the existing MFHI1 and MFLO1 opcodes.

The virt machine already checks KVM_CAP_ARM_VM_IPA_SIZE to get the
upper bound of the IPA size. If that bound is lower than the highest
possible GPA for the machine, then QEMU will error out. However, the
IPA is set to 40 when the highest GPA is less than or equal to 40,
even when KVM may support an IPA limit as low as 32. This means KVM
may fail the VM creation unnecessarily. Additionally, 40 is selected
with the value 0, which means use the default, and that gets around
a check in some versions of KVM, causing a difficult to debug fail.
Always use the IPA size that corresponds to the highest possible GPA,
unless it's lower than 32, in which case use 32. Also, we must still
use 0 when KVM only supports the legacy fixed 40 bit IPA.

With the reduction operations, we intentionally increase maxsz to
the next power of 2, so as to fill out the reduction tree correctly.
Since e2e7168a214b, oprsz must equal maxsz, with exceptions for small
vectors, so this triggers an assertion for vector sizes > 32 that are
not themselves a power of 2.
Pass the power-of-two value in the simd_data field instead.

According to the M68040UM Appendix D the requirement for data accesses to be
word aligned is only for the 68000, 68008 and 68010 CPUs. Later CPUs from the
68020 onwards will allow unaligned data accesses but at the cost of being less
efficient.
Add a new M68K_FEATURE_UNALIGNED_DATA feature to specify that data accesses are
not required to be word aligned, and don't perform the alignment on the stack
pointer when taking an exception if this feature is not selected.
This is required because the MacOS DAFB driver attempts to call an A-trap
with a byte-aligned stack pointer during initialisation and without this the
stack pointer is off by one when the A-trap returns.

If a NuBus slot doesn't contain a card, the Quadra hardware generates a physical
bus error if the CPU attempts to access the slot address space. Both Linux and
MacOS use a separate bus error handler during NuBus accesses in order to detect
and recover when addressing empty slots.
According to the MC68040 users manual the ATC bit of the SSW is used to
distinguish between ATC faults and physical bus errors. MacOS specifically checks
the stack frame generated by a NuBus error and panics if the SSW ATC bit is set.
Update m68k_cpu_transaction_failed() so that the SSW ATC bit is not set if the
memory API returns MEMTX_DECODE_ERROR which will be used to indicate that an
access to an empty NuBus slot occurred.

The commit d03b174a83 (target/ppc: simplify bcdadd/sub functions)
meant to simplify some of the code but it inadvertently altered the
way the CR6 field is set after the operation has overflowed.
The CR6 bits are set based on the *unbounded* result of the operation,
so we need to look at the result before returning from bcd_add_mag,
otherwise we will look at 0 when it overflows.
Consider the following subtraction:
v0 = 0x9999999999999999999999999999999c (maximum positive BCD value)
v1 = 0x0000000000000000000000000000001d (negative one BCD value)
bcdsub. v0,v0,v1,0
The Power ISA 2.07B says:
If the unbounded result is greater than zero, do the following.
If PS=0, the sign code of the result is set to 0b1100.
If PS=1, the sign code of the result is set to 0b1111.
If the operation overflows, CR field 6 is set to 0b0101. Otherwise,
CR field 6 is set to 0b0100.
POWER9 hardware:
vr0 = 0x0000000000000000000000000000000c (positive zero BCD value)
cr6 = 0b0101 (0x5) (positive, overflow)
QEMU:
vr0 = 0x0000000000000000000000000000000c (positive zero BCD value)
cr6 = 0b0011 (0x3) (zero, overflow) <--- wrong
This patch reverts the part of d03b174a83 that introduced the
problem and adds a test-case to avoid further regressions:
before:
$ make run-tcg-tests-ppc64le-linux-user
(...)
TEST bcdsub on ppc64le
bcdsub: qemu/tests/tcg/ppc64le/bcdsub.c:58: test_bcdsub_gt:
Assertion `(cr >> 4) == ((1 << 2) | (1 << 0))' failed.
