It is ok to use 2MB paging in map_linear
BUT in map_alloc, how to handle 2MB page fault for mappings without populated flag?
I believe that there is a way, BUT not well supported in current page_table_multiarch

Agree. I think a co-design is necessary.

如hky说的那个关于populated 的问题，咱们提交的修改还是尽量考虑覆盖之前的不同情况；如果有目前确实不易处理的分支情况，至少先暂时给出个临时的处理方式，后续在逐步解决。另外，提交时最好还是写一下总的意图和想法，或者给一个指向Issue的链接。
