The SoundWire 1.1 specification only allowed for reads and writes of
bytes. The SoundWire 1.2 specification adds a new capability to
transfer "Multi-Byte Quantities" (MBQ) across the bus. The transfers
still happens one-byte-at-a-time, but the update is atomic.
For example when writing a 16-bit vo
The x86 uaccess code uses barrier_nospec() in various places to prevent

combined with further gadgets or CPU bugs to leak data).
