However we never actually use the TLB -- all stage 2 lookups are done by direct calls to get_phys_addr_lpae() followed by a physical address load via address_space_ld*(). Remove Stage2 from the list of ARM MMU indexes which correspond to real core MMU indexes, and instead put it in the set of "NOTLB" ARM MMU indexes. This allows us to drop NB_MMU_MODES to 11. It also means we can safely add support for the ARMv8.3-TTS2UXN extension, which adds permission bits to the stage 2 descriptors which define execute permission separatel for EL0 and EL1; supporting that while keeping Stage2 in a QEMU TLB would require us to use separate TLBs for "Stage2 for an EL0 access" and "Stage2 for an EL1 access", which is a lot of extra complication given we aren't even using the QEMU TLB.

For ID_AA64DFR0 we accidentally used 'u', meaning that the top 32 bits of this 64-bit ID register would end up always zero.

In order to share the decode files between A32 and T32, we split Neon into 3 parts: * data-processing * load-store * 'shared' encodings The first two groups of instructions have similar but not identical A32 and T32 encodings, so we need to manually transform the T32 encoding into the A32 one before calling the decoder; the third group covers the Neon instructions which are identical in A32 and T32.

It never caused any problems by pure luck: We were not setting class_size for TYPE_ARM_SSE, so class_size of TYPE_SYS_BUS_DEVICE was being used (sizeof(SysBusDeviceClass)). This made the system allocate enough memory for TYPE_ARM_SSE devices even though ARMSSEClass was too small for a sysbus device. Additionally, the ARMSSEClass::info field ended up at the same offset as SysBusDeviceClass::explicit_ofw_unit_address. This would make sysbus_get_fw_dev_path() crash for the device. Luckily, sysbus_get_fw_dev_path() never gets called for TYPE_ARM_SSE devices, because qdev_get_fw_dev_path() is only used by the boot device code, and TYPE_ARM_SSE devices don't appear at the fw_boot_order list.
