In commit 39a1fd2528 we fixed a bug in the handling of LPAE block
descriptors where we weren't correctly zeroing out some RES0 bits.
However this fix has a bug because the calculation of the mask is
done at the wrong width: in
descaddr &= ~(page_size - 1);
page_size is a target_ulong, so in the 'qemu-system-arm' binary it is
only 32 bits, and the effect is that we always zero out the top 32
bits of the calculated address. Fix the calculation by forcing the
mask to be calculated with the same type as descaddr.
This only affects 32-bit CPUs which support LPAE (e.g. cortex-a15)
when used on board models which put RAM or devices above the 4GB
mark and when the 'qemu-system-arm' executable is being used.
It was also masked in 7.0 by the main bug reported in
https://gitlab.com/qemu-project/qemu/-/issues/1078 where the
virt board incorrectly does not enable 'highmem' for 32-bit CPUs.
The workaround is to use 'qemu-system-aarch64' with the same
command line.

The architecture defines the OS DoubleLock as a register which
(similarly to the OS Lock) suppresses debug events for use in CPU
powerdown sequences. This functionality is required in Arm v7 and
v8.0; from v8.2 it becomes optional and in v9 it must not be
implemented.
Currently in QEMU we implement the OSDLR_EL1 register as a NOP. This
is wrong both for the "feature implemented" and the "feature not
implemented" cases: if the feature is implemented then the DLK bit
should read as written and cause suppression of debug exceptions, and
if it is not implemented then the bit must be RAZ/WI.

Starting with v7 of the debug architecture, there are three extra
ID registers that add information on top of that provided in
DBGDIDR. These are DBGDEVID, DBGDEVID1 and DBGDEVID2. In the
v7 debug architecture, DBGDEVID is optional, present only of
DBGDIDR.DEVID_imp is set. In v7.1 all three must be present.
Implement the missing registers. Note that we only need to set the
values in the ARMISARegisters struct for the CPUs Cortex-A7, A15,
A53, A57 and A72 (plus the 32-bit 'max' which uses the Cortex-A53
values): earlier CPUs didn't implement v7 of the architecture, and
our other 64-bit CPUs (Cortex-A76, Neoverse-N1 and A64fx) don't have
AArch32 support at EL1.

The "OS Lock" in the Arm debug architecture is a way for software
to suppress debug exceptions while it is trying to power down
a CPU and save the state of the breakpoint and watchpoint
registers. In QEMU we implemented the support for writing
the OS Lock bit via OSLAR_EL1 and reading it via OSLSR_EL1,
but didn't implement the actual behaviour.
The required behaviour with the OS Lock set is:
* debug exceptions (apart from BKPT insns) are suppressed
* some MDSCR_EL1 bits allow write access to the corresponding
EDSCR external debug status register that they shadow
(we can ignore this because we don't implement external debug)
* similarly with the OSECCR_EL1 which shadows the EDECCR
(but we don't implement OSECCR_EL1 anyway)
Implement the missing behaviour of suppressing debug
exceptions.

Use the function instead of the array directly.
Because the function performs its own masking, via the uint8_t
parameter, we need to do nothing extra within the users: the bits
above the first 2 (_uh) or 4 (_uw) will be discarded by assignment
to the local bmask variables, and of course _uq uses the entire

The FEAT_DoubleFault extension adds the following:
* All external aborts on instruction fetches and translation table
walks for instruction fetches must be synchronous. For QEMU this
is already true.
* SCR_EL3 has a new bit NMEA which disables the masking of SError
interrupts by PSTATE.A when the SError interrupt is taken to EL3.
For QEMU we only need to make the bit writable, because we have no
sources of SError interrupts.
* SCR_EL3 has a new bit EASE which causes synchronous external
aborts taken to EL3 to be taken at the same entry point as SError.
(Note that this does not mean that they are SErrors for purposes
of PSTATE.A masking or that the syndrome register reports them as
SErrors: it just means that the vector offset is different.)
* The existing SCTLR_EL3.IESB has an effective value of 1 when
SCR_EL3.NMEA is 1. For QEMU this is a no-op because we don't need
different behaviour based on IESB (we don't need to do anything to
ensure that error exceptions are synchronized).
So for QEMU the things we need to change are:
* Make SCR_EL3.{NMEA,EASE} writable
* When taking a synchronous external abort at EL3, adjust the
vector entry point if SCR_EL3.EASE is set
* Advertise the feature in the ID registers

The architectural feature RASv1p1 introduces the following new
features:
* new registers ERXPFGCDN_EL1, ERXPFGCTL_EL1 and ERXPFGF_EL1
* new bits in the fine-grained trap registers that control traps
for these new registers
* new trap bits HCR_EL2.FIEN and SCR_EL3.FIEN that control traps
for ERXPFGCDN_EL1, ERXPFGCTL_EL1, ERXPFGP_EL1
* a larger number of the ERXMISC<n>_EL1 registers
* the format of ERR<n>STATUS registers changes
The architecture permits that if ERRIDR_EL1.NUM is 0 (as it is for
QEMU) then all these new registers may UNDEF, and the HCR_EL2.FIEN
and SCR_EL3.FIEN bits may be RES0. We don't have any ERR<n>STATUS
registers (again, because ERRIDR_EL1.NUM is 0). QEMU does not yet
implement the fine-grained-trap extension. So there is nothing we
need to implement to be compliant with the feature spec. Make the
'max' CPU report the feature in its ID registers, and document it.

The decode for RAX1 sets esz to MO_8, because that's what
we use by default for "no esz present". We changed that
to MO_64 during translation because it is more logical for
the operation. However, the esz argument to gen_gvec_rax1
is unused and forces MO_64 within that function, so there
is no need to do it here as well.
Simplify to use gen_gvec_fn_arg_zzz and TRANS_FEAT.
