Merge Pull Request from: @Linwang_68f8 
 
Content:
Intel® Advanced Matrix Extensions (Intel® AMX) is a new 64-bit programming paradigm consisting of two components: a set of 2-dimensional registers (tiles) representing sub-arrays from a larger 2-dimensional memory image, and an accelerator able to operate on tiles, the first implementation is called TMUL (tile matrix multiply unit).

This patch set involves 182 patches including KABI fixes from Zheng Zengkai <zhengzengkai@huawei.com>

Please be noticed that to keep KABI consistency following 9 commits have to be dropped:
