This includes the reset method function signature change, so it has some chance of compile failures due to merge conflicts if some other pullreq added a device reset method and that pullreq got applied before this one. If so, the changes needed to fix those up can be created by running the spatch rune described in the commit message of the "hw, target: Add ResetType argument to hold and exit phase methods" commit.

As Richard suggested, place ALLINT bit in PSTATE in env->pstate. In the pseudocode, AArch64.ExceptionReturn() calls SetPSTATEFromPSR(), which treats PSTATE.ALLINT as one of the bits which are reinstated from SPSR to PSTATE regardless of whether this is an illegal exception return or not. So handle PSTATE.ALLINT the same way as PSTATE.DAIF in the illegal_return exit path of the exception_return helper. With the change, exception entry and return are automatically handled.

We don't need to gate the enabling of NMI in the GIC behind a machine version property, because none of our current CPUs implement FEAT_NMI, and '-cpu max' is not something we maintain migration compatibility across versions for.

This doesn't happen in practice for our current use of this code, because the worst case is when we call soc_dma_init() with an argument of 32 for the number of channels, and QEMU builds with -fwrapv so the shift into the sign bit is well-defined. However, it's obviously not the intended behaviour of the code. Add casts to force the shift to be done as 64-bit arithmetic, allowing up to 64 channels.

This is different from how every other three-phase-reset method we have works, and makes it difficult to add new reset types. A better pattern is "assume that any reset type you don't know about should be handled like RESET_TYPE_COLD"; switch these devices to do that. Then adding a new reset type will only need to touch those devices where its behaviour really needs to be different from the standard cold reset.

Currently this kind of reset handling is supported only for: * TYPE_MACHINE reset methods, which take a ShutdownCause argument * reset functions registered with qemu_register_reset_nosnapshotload To allow a three-phase-reset device to also distinguish "snapshot load" reset from the normal kind, add a new ResetType RESET_TYPE_SNAPSHOT_LOAD. All our existing reset methods ignore the reset type, so we don't need to update any device code. Add the enum type, and make qemu_devices_reset() use the right reset type for the ShutdownCause it is passed. This allows us to get rid of the device_reset_reason global we were using to implement qemu_register_reset_nosnapshotload().
