feat: mm: added affinity pages allocator

2025-02-25T03:26:30Z

This patch introduces a tagged pages allocator to address the existing problems of page aliasing on specific platforms and the requirement of page coloring. It implements an affinity-id aware page manager by separating the runtime page list into two types: a normal single linked-list and a multi-dimensional affinity-list. Changes: - Introduced tagged pages allocator and managing algorithm for affinity pages list - Modified components to support affinity-id list management - Updated page allocation and freeing functions to handle tagged pages - Added configuration options for page affinity block size and debugging - Modified mmap and elf loading to respect affinity settings - Enhanced page list management to support multi-dimensional affinity-list Signed-off-by: Shell
