This is a respin of Eric's work, but not making tpm_crb.c target specific. Based-on: <20220120000836.229419-1-f4...@amsat.org> "exec/cpu: Make host pages variables / macros 'target agnostic'" https://lore.kernel.org/qemu-devel/20220120000836.229419-1-f4...@amsat.org/
-- Eric's v2 cover: This series aims at removing a spurious error message we get when launching a guest with a TPM-CRB device and VFIO-PCI devices. The CRB command buffer currently is a RAM MemoryRegion and given its base address alignment, it causes an error report on vfio_listener_region_add(). This series proposes to use a ram-device region instead which helps in better assessing the dma map error failure on VFIO side.
