Start switching iomap_copy routines over to use #define and arch provided inline/macro functions instead of weak symbols. Inline functions allow more compiler optimization and this is often a driver hot path. x86 has the only weak implementation for __iowrite32_copy(), so replace it with a static inline containing the same single instruction inline assembly. The compiler will generate the "mov edx,ecx" in a more optimal way. Remove iomap_copy_64.S Link: https://lore.kernel.org/r/1-v3-1893cd8b9369+1925-mlx5_arm_wc_jgg@nvidia.com Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> |
