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> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
