Subject: [PATCH v4 0/5] Consolidate IO memcpy functions
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.
Signed-off-by: Julian Vetter <jvetter@...rayinc.com>

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
