When THP is enabled, the allocation of a page(order=0) may be converted to
an allocation of pages(order>0). In this case, the allocation will skip the
dhugetlb_pool. When we want to use dynamic hugetlb feature, we have to
disable THP for now.

CVE: NA

--------------------------------

Dynamic hugetlb is a self-developed feature based on the hugetlb and memcontrol.
It supports to split huge page dynamically in a memory cgroup. There is a new structure
dhugetlb_pool in every mem_cgroup to manage the pages configured to the mem_cgroup.
For the mem_cgroup configured with dhugetlb_pool, processes in the mem_cgroup will
preferentially use the pages in dhugetlb_pool.

Dynamic hugetlb supports three types of pages, including 1G/2M huge pages and 4K pages.
For the mem_cgroup configured with dhugetlb_pool, processes will be limited to alloc
1G/2M huge pages only from dhugetlb_pool. But there is no such constraint for 4K pages.
If there are insufficient 4K pages in the dhugetlb_pool, pages can also be allocated from
buddy system. So before using dynamic hugetlb, user must know how many huge pages they
need.

Usage:
1. Add 'dynamic_hugetlb=on' in cmdline to enable dynamic hugetlb feature.
2. Prealloc some 1G hugepages through hugetlb.
3. Create a mem_cgroup and configure dhugetlb_pool to mem_cgroup.
4. Configure the count of 1G/2M hugepages, and the remaining pages in dhugetlb_pool will
   be used as basic pages.
5. Bound a process to mem_cgroup. then the memory for it will be allocated from dhugetlb_pool.

This patch add the corresponding structure dhugetlb_pool for dynamic hugetlb feature,
the interface 'dhugetlb.nr_pages' in mem_cgroup to configure dhugetlb_pool and the cmdline
'dynamic_hugetlb=on' to enable dynamic hugetlb feature.

For memory accesses with write-combining attributes (e.g. those returned

subsequent ones. But in some situation, such wait is bad for the

We introduce io_stop_wc() to prevent the merging of write-combining

We add implementation for ARM64 using DGH instruction and provide NOP
implementation for other architectures.

category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4QOTS
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?id=0e60778efb072d47efc7100c4009b5bd97273b0b

The upper limit of MAX_LP_MSG_LEN on HIP08 is 64K, and the upper limit on
HIP09 is 16K. Regardless of whether it is HIP08 or HIP09, only 16K will be
used. In order to ensure compatibility, it is unified to 16K.

Setting MAX_LP_MSG_LEN to 16K will not cause performance loss on HIP08.

We set the init CQ status to ARMED before. As a result, an unexpected CEQE
would be reported. Therefore, the init CQ status should be set to no_armed
rather than REG_NXT_CEQE.
