When HCR_EL2.{NV,NV1} is {1,1} we must trap five extra registers to
EL2: VBAR_EL1, ELR_EL1, SPSR_EL1, SCXTNUM_EL1 and TFSR_EL1.
Implement these traps.
This trap does not apply when FEAT_NV2 is implemented and enabled;
include the check that HCR_EL2.NV2 is 0 here, to save us having
to come back and add it later.

FEAT_NV requires that when HCR_EL2.{NV,NV1} == {1,0} and an exception
is taken from EL1 to EL1 then the reported EL in SPSR_EL1.M should be
EL2, not EL1. Implement this behaviour.

For FEAT_NV, accesses to system registers and instructions from EL1
which would normally UNDEF there but which work in EL2 need to
instead be trapped to EL2. Detect this both for "we know this will
UNDEF at translate time" and "we found this UNDEFs at runtime", and
make the affected registers trap to EL2 instead.
The Arm ARM defines the set of registers that should trap in terms
of their names; for our implementation this would be both awkward
and inefficent as a test, so we instead trap based on the opc1
field of the sysreg. The regularity of the architectural choice
of encodings for sysregs means that in practice this captures
exactly the correct set of registers.
Regardless of how we try to define the registers this trapping
applies to, there's going to be a certain possibility of breakage
if new architectural features introduce new registers that don't
follow the current rules (FEAT_MEC is one example already visible
in the released sysreg XML, though not yet in the Arm ARM). This
approach seems to me to be straightforward and likely to require
a minimum of manual overrides.

In handle_sys() we don't do the check for whether the register is
marked as needing an FPU/SVE/SME access check until after we've
handled the special cases covered by ARM_CP_SPECIAL_MASK. This is
conceptually the wrong way around, because if for example we happen
to implement an FPU-access-checked register as ARM_CP_NOP, we should
do the access check first.
Move the access checks up so they are with all the other access
checks, not sandwiched between the special-case read/write handling
and the normal-case read/write handling. This doesn't change
behaviour at the moment, because we happen not to define any
cpregs with both ARM_CPU_{FPU,SVE,SME} and one of the cases
dealt with by ARM_CP_SPECIAL_MASK.
Moving this code also means we have the correct place to put the
FEAT_NV/FEAT_NV2 access handling, which should come after the access
checks and before we try to do any read/write action.

FEAT_NV and FEAT_NV2 will allow EL1 to attempt to access cpregs that
only exist at EL2. This means we're going to want to run their
accessfns when the CPU is at EL1. In almost all cases, the behaviour
we want is "the accessfn returns OK if at EL1".
Mostly the accessfn already does the right thing; in a few cases we
need to explicitly check that the EL is not 1 before applying various
trap controls, or split out an accessfn used both for an _EL1 and an
_EL2 register into two so we can handle the FEAT_NV case correctly
for the _EL2 register.
There are two registers where we want the accessfn to trap for
a FEAT_NV EL1 access: VSTTBR_EL2 and VSTCR_EL2 should UNDEF
an access from NonSecure EL1, not trap to EL2 under FEAT_NV.
The way we have written sel2_access() already results in this
behaviour.
We can identify the registers we care about here because they
all have opc1 == 4 or 5.

The alias registers like SCTLR_EL12 only exist when HCR_EL2.E2H
is 1; they should UNDEF otherwise. We weren't implementing this.
Add an intercept of the accessfn for these aliases, and implement

For FEAT_VHE, we define a set of register aliases, so that for instance:
* the SCTLR_EL1 either accesses the real SCTLR_EL1, or (if E2H is 1)
SCTLR_EL2
* a new SCTLR_EL12 register accesses SCTLR_EL1 if E2H is 1
However when we create the 'new_reg' cpreg struct for the SCTLR_EL12
register, we duplicate the information in the SCTLR_EL1 cpreg, which
means the opcode fields are those of SCTLR_EL1, not SCTLR_EL12. This
is a problem for code which looks at the cpreg opcode fields to
determine behaviour (e.g. in access_check_cp_reg()). In practice
the current checks we do there don't intersect with the *_EL12
registers, but for FEAT_NV this will become a problem.
Write the correct values from the encoding into the new_reg struct.
This restores the invariant that the cpreg that you get back
from the hashtable has opcode fields that match the key you used
to retrieve it.
When we call the readfn or writefn for the target register, we
pass it the cpreg struct for that target register, not the one
for the alias, in case the readfn/writefn want to look at the
opcode fields to determine behaviour. This means we need to
interpose custom read/writefns for the e12 aliases.

The TBFLAG_A64 TB flag bits go in flags2, which for AArch64 guests
we know is 64 bits. However at the moment we use FIELD_EX32() and
FIELD_DP32() to read and write these bits, which only works for
bits 0 to 31. Since we're about to add a flag that uses bit 32,
switch to FIELD_EX64() and FIELD_DP64() so that this will work.

The HCR_EL2.TSC trap for trapping EL1 execution of SMC instructions
has a behaviour change for FEAT_NV when EL3 is not implemented:
* in older architecture versions TSC was required to have no
effect (i.e. the SMC insn UNDEFs)
* with FEAT_NV, when HCR_EL2.NV == 1 the trap must apply
(i.e. SMC traps to EL2, as it already does in all cases when
EL3 is implemented)
* in newer architecture versions, the behaviour either without
FEAT_NV or with FEAT_NV and HCR_EL2.NV == 0 is relaxed to
an IMPDEF choice between UNDEF and trap-to-EL2 (i.e. it is
permitted to always honour HCR_EL2.TSC) for AArch64 only
Add the condition to honour the trap bit when HCR_EL2.NV == 1. We
leave the HCR_EL2.NV == 0 case with the existing (UNDEF) behaviour,
as our IMPDEF choice (both because it avoids a behaviour change
for older CPU models and because we'd have to distinguish AArch32
from AArch64 if we opted to trap to EL2).

When FEAT_NV is turned on via the HCR_EL2.NV bit, ERET instructions
are trapped, with the same syndrome information as for the existing
FEAT_FGT fine-grained trap (in the pseudocode this is handled in
AArch64.CheckForEretTrap()).
Rename the DisasContext and tbflag bits to reflect that they are
no longer exclusively for FGT traps, and set the tbflag bit when
FEAT_NV is enabled as well as when the FGT is enabled.

The CTR_EL0 register has some bits which allow the implementation to
tell the guest that it does not need to do cache maintenance for
data-to-instruction coherence and instruction-to-data coherence.
QEMU doesn't emulate caches and so our cache maintenance insns are
all NOPs.
We already have some models of specific CPUs where we set these bits
(e.g. the Neoverse V1), but the 'max' CPU still uses the settings it
inherits from Cortex-A57. Set the bits for 'max' as well, so the
guest doesn't need to do unnecessary work.

The Big QEMU Lock (BQL) has many names and they are confusing. The
actual QemuMutex variable is called qemu_global_mutex but it's commonly
referred to as the BQL in discussions and some code comments. The
locking APIs, however, are called qemu_mutex_lock_iothread() and
qemu_mutex_unlock_iothread().
The "iothread" name is historic and comes from when the main thread was
split into into KVM vcpu threads and the "iothread" (now called the main
loop thread). I have contributed to the confusion myself by introducing
a separate --object iothread, a separate concept unrelated to the BQL.
The "iothread" name is no longer appropriate for the BQL. Rename the
locking APIs to:
- void bql_lock(void)
- void bql_unlock(void)
- bool bql_locked(void)
There are more APIs with "iothread" in their names. Subsequent patches
will rename them. There are also comments and documentation that will be
updated in later patches.

Drop fprintfs and actually use the return values in the callers.
This is OK to do since commit 7191f24c7fcf which added the

There is no need to do this in kvm_arch_init_vcpu per vcpu.
Inline kvm_arm_init_serror_injection rather than keep separate.
