Thank you again for your feedback. Sorry for the delay, I didn't see the
remarks you made on v2 of the patchset in regards to the
asm-generic/io.h. This patchset takes your remarks on v2 into account.

Changes for v4:
- Replaced memcpy/memset in asm-generic/io.h by the new
  __memcpy_{to,from}io and __memset_io, so individual architectures can
  use it instead of using their own implementation.
---
Julian Vetter (5):
  Consolidate __memcpy_{to,from}io and __memset_io into a single lib
  Replace generic memcpy and memset by IO memcpy functions
  Use generic io memcpy functions on the arm64 architecture
  Use generic io memcpy functions on the csky architecture
  Use generic io memcpy functions on the loongarch architecture
