Persistent dirty bitmaps will be saved into qcow2 files. It may be used as 'internal' bitmaps (for qcow2 drives) or as 'external' bitmaps for other drives (there may be qcow2 file with zero disk size but with several dirty bitmaps for other drives). Signed-off-by: Vladimir Sementsov-Ogievskiy ---

Most ARM cores switch unconditionally to ARM mode when an exception occurs; some Cortex variants have a "Thumb-exception enable" bit in the system control register that allows an unconditional switch to Thumb mode instead when handling exceptions. The presence of this bit seems unrelated to th
