The current implementation will disable the guest Intel PT feature
if the Intel PT LIP feature is supported on the host, but the LIP
feature is comming soon(e.g. SnowRidge and later).
This patch will make the guest LIP feature configurable and Intel
PT feature can be enabled in guest when the guest LIP status same
with the host.

AMD SEV allows a guest owner to inject a secret blob

encrypted with the SEV Transport Encryption Key and
integrity is guaranteed with the Transport Integrity

This patch adds support the kernel-irqchip option for
WHPX with on or off value. 'split' value is not supported
for the option. The option only works for the latest version
of Windows (ones that are coming out on Insiders). The
change maintains backward compatibility on older version of
Windows where this option is not supported.

RET/IRET helper
Per the SDM, when returning to outer privilege level, for segment
registers (ES, FS, GS, and DS) if the check fails, the segment
selector becomes null, but QEMU clears the base/limit/flags as well
as nullifying the segment selector, which should be a spec violation.
Real hardware seems to be compliant with the spec, at least on one
Coffee Lake board I tested.

The IOAPIC has an 'Extended Destination ID' field in its RTE, which maps
to bits 11-4 of the MSI address. Since those address bits fall within a
given 4KiB page they were historically non-trivial to use on real hardware.
The Intel IOMMU uses the lowest bit to indicate a remappable format MSI,
and then the remaining 7 bits are part of the index.
Where the remappable format bit isn't set, we can actually use the other
seven to allow external (IOAPIC and MSI) interrupts to reach up to 32768
CPUs instead of just the 255 permitted on bare metal.

For v8.1M the architecture mandates that CPUs must provide at
least the "minimal RAS implementation" from the Reliability,
Availability and Serviceability extension. This consists of:
* an ESB instruction which is a NOP
-- since it is in the HINT space we need only add a comment
* an RFSR register which will RAZ/WI
* a RAZ/WI AIRCR.IESB bit
-- the code which handles writes to AIRCR does not allow setting
of RES0 bits, so we already treat this as RAZ/WI; add a comment
noting that this is deliberate
* minimal implementation of the RAS register block at 0xe0005000
-- this will be in a subsequent commit
* setting the ID_PFR0.RAS field to 0b0010
-- we will do this when we add the Cortex-M55 CPU model

v8.1M adds new encodings of VLLDM and VLSTM (where bit 7 is set).
The only difference is that:
* the old T1 encodings UNDEF if the implementation implements 32
Dregs (this is currently architecturally impossible for M-profile)
* the new T2 encodings have the implementation-defined option to
read from memory (discarding the data) or write UNKNOWN values to
memory for the stack slots that would be D16-D31
We choose not to make those accesses, so for us the two
instructions behave identically assuming they don't UNDEF.

In v8.1M a new exception return check is added which may cause a NOCP
UsageFault (see rule R_XLTP): before we clear s0..s15 and the FPSCR
we must check whether access to CP10 from the Security state of the
returning exception is disabled; if it is then we must take a fault.
(Note that for our implementation CPPWR is always RAZ/WI and so can
never cause CP10 accesses to fail.)
The other v8.1M change to this register-clearing code is that if MVE
is implemented VPR must also be cleared, so add a TODO comment to
that effect.

In v8.0M, on exception entry the registers R0-R3, R12, APSR and EPSR
are zeroed for an exception taken to Non-secure state; for an
exception taken to Secure state they become UNKNOWN, and we chose to

In v8.1M the behaviour is specified more tightly and these registers

Currently M-profile borrows the A-profile code for VMSR and VMRS
(access to the FP system registers), because all it needs to support
is the FPSCR. In v8.1M things become significantly more complicated
in two ways:
* there are several new FP system registers; some have side effects
on read, and one (FPCXT_NS) needs to avoid the usual
vfp_access_check() and the "only if FPU implemented" check
* all sysregs are now accessible both by VMRS/VMSR (which
reads/writes a general purpose register) and also by VLDR/VSTR
(which reads/writes them directly to memory)
Refactor the structure of how we handle VMSR/VMRS to cope with this:
* keep the M-profile code entirely separate from the A-profile code
* abstract out the "read or write the general purpose register" part
of the code into a loadfn or storefn function pointer, so we can
reuse it for VLDR/VSTR.

For M-profile before v8.1M, the only valid register for VMSR/VMRS is
the FPSCR. We have a comment that states this, but the actual logic
to forbid accesses for any other register value is missing, so we

In arm_cpu_realizefn() we check whether the board code disabled EL3
via the has_el3 CPU object property, which we create if the CPU
starts with the ARM_FEATURE_EL3 feature bit. If it is disabled, then
we turn off ARM_FEATURE_EL3 and also zero out the relevant fields in
the ID_PFR1 and ID_AA64PFR0 registers.
This codepath was incorrectly being taken for M-profile CPUs, which
do not have an EL3 and don't set ARM_FEATURE_EL3, but which may have
the M-profile Security extension and so should have non-zero values
in the ID_PFR1.Security field.
Restrict the handling of the feature flag to A/R-profile cores.

The semihosting SYS_HEAPINFO call is supposed to return an array
of four guest addresses:
* base of heap memory
* limit of heap memory
* base of stack memory
* limit of stack memory
Some semihosting programs (including those compiled to use the
'newlib' embedded C library) use this call to work out where they
should initialize themselves to.
QEMU's implementation when in system emulation mode is very
simplistic: we say that the heap starts halfway into RAM and
continues to the end of RAM, and the stack starts at the top of RAM
and works down to the bottom. Unfortunately the code assumes that
the base address of RAM is at address 0, so on boards like 'virt'
where this is not true the addresses returned will all be wrong and
the guest application will usually crash.
Conveniently since all Arm boards call arm_load_kernel() we have the
base address of the main RAM block in the arm_boot_info struct which
is accessible via the CPU object. Use this to return sensible values
from SYS_HEAPINFO.

In the mtspr helper we attempt to check for "is the timer disabled"
with "if (env->ttmr & TIMER_NONE)". This is wrong because TIMER_NONE
is zero and the condition is always false (Coverity complains about
the dead code.)
The correct check would be to test whether the TTMR_M field in the
register is equal to TIMER_NONE instead. However, the
cpu_openrisc_timer_update() function checks whether the timer is
enabled (it looks at cpu->env.is_counting, which is set to 0 via
cpu_openrisc_count_stop() when the TTMR_M field is set to
TIMER_NONE), so there's no need to check for "timer disabled" in the
target/openrisc code. Instead, simply remove the dead code.

The size of env->mmu.regs is 3, but the range of 'rn' is [0, 5].
To avoid data access out of bounds, only if 'rn' is less than 3, we
can print env->mmu.regs[rn]. In other cases, we can print
env->mmu.regs[MMU_R_TLBX].

g_strdup_printf is used twice to write to the same variable, which
can theoretically cause a leak. In practice, it is extremely
unlikely that a guest is seeing a recursive MCE and has disabled
CR4.MCE between the first and the second error, but we can fix it
and we can also make a slight improvement on the logic: CR4.MCE=0
causes a triple fault even for a non-recursive machine check, so
let's place its test first.

Currently, the nested state format is hardcoded to VMX. This will result
in kvm_put_nested_state() returning an error because the KVM SVM support
checks for the nested state to be KVM_STATE_NESTED_FORMAT_SVM. As a
result, kvm_arch_put_registers() errors out early.
Update the setting of the format based on the virtualization feature:
VMX - KVM_STATE_NESTED_FORMAT_VMX
SVM - KVM_STATE_NESTED_FORMAT_SVM
Also, fix the code formatting while at it.
