..just like the rest of the displayed ESR register. Otherwise people
might scratch their heads if a not obviously hex number is displayed
for the EC field.

While the vargs approach was flexible the original MTTCG ended up
having munge the bits to a bitmap so the data could be used in
deferred work helpers. Instead of hiding that in cputlb we push the
change to the API to make it take a bitmap of MMU indexes instead.
For ARM some the resulting flushes end up being quite long so to aid
readability I've tended to move the index shifting to a new line so
all the bits being or-ed together line up nicely, for example:
tlb_flush_page_by_mmuidx(other_cs, pageaddr,
(1 << ARMMMUIdx_S1SE1) |
(1 << ARMMMUIdx_S1SE0));
Backports commit 0336cbf8532935d8e23c2aabf3e2ce2c0697b6ac from qemu
This patch contains several fixes to enable vPMU under TCG mode. It
first removes the checking of kvm_enabled() while unsetting
ARM_FEATURE_PMU. With it, the .pmu option can be used to turn on/off vPMU
under TCG mode. Secondly the PMU node of DT table is now created under TCG.
The last fix is to disable the masking of PMUver field of ID_AA64DFR0_EL1.

In order to support Linux perf, which uses PMXEVTYPER register,
this patch adds read/write access support for PMXEVTYPER. The access
is CONSTRAINED UNPREDICTABLE when PMSELR is not 0x1f. Additionally
this patch adds support for PMXEVTYPER_EL0.
Backports commit fdb8665672ded05f650d18f8b62d5c8524b4385b from qemu
This patch adds support for AArch64 register PMSELR_EL0. The existing
PMSELR definition is revised accordingly.
Backports commit 6b0407805d46bbeba70f4be426285d0a0e669750 from qemu
We only use the IS_M() macro in two places, and it's a bit of a
namespace grab to put in cpu.h. Drop it in favour of just explicitly
calling arm_feature() in the places where it was used.
Backports commit 531c60a97ab51618b4b9ccef1c5fe00607079706 from qemu
The DBGVCR_EL2 system register is needed to run a 32-bit
EL1 guest under a Linux EL2 64-bit hypervisor. Its only
purpose is to provide AArch64 with access to the state of
the DBGVCR AArch32 register. Since we only have a dummy
DBGVCR, implement a corresponding dummy DBGVCR32_EL2.
Backports commit 4d2ec4da1c2d60c9fd8bad137506870c2f980410 from qemu
To run a VM in 32-bit EL1 our AArch32 interrupt handling code
needs to be able to cope with VIRQ and VFIQ exceptions.
These behave like IRQ and FIQ except that we don't need to try
to route them to Monitor mode.
Backports commit 87a4b270348c69a446ebcddc039bfae31b1675cb from qemu
We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
