6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Aharon Landau <aharonl@xxxxxxxxxx> [ Upstream commit a2a88b8e22d1b202225d0e40b02ad068afab2ccb ] mkc.log_page_size can be changed using UMR. Therefore, don't treat it as a cache entry property. Removing it from struct mlx5_cache_ent. All cache mkeys will be created with default PAGE_SHIFT, and updated with the needed page_shift using UMR when passing them to a user.
