+ hugetlb-really-allocate-vma-lock-for-all-sharable-vmas.patch added to mm-hotfixes-unstable branch

However, it left the functional version of helper routines behind #ifdef CONFIG_ARCH_WANT_HUGE_PMD_SHARE. Therefore, the vma lock is not being used for sharable vmas on architectures that do not support pmd sharing. On these architectures, a potential fault/truncation race is exposed that could leave pages in a hugetlb file past i_size until the file is removed. Move the functional vma lock helpers outside the ifdef, and remove the non-functional stubs. Since the vma lock is not just for pmd sharing, rename the routine __vma_shareable_flags_pmd.

Patch 1 resolves the syzkiller report from Pengfei. Patch 2 further harden pte markers when used with the recent swapin error markers. The major case is we should persist a swapin error marker after fork(), so child shouldn't read a corrupted page. This patch (of 2): When fork(), dst_vma is not guaranteed to have VM_UFFD_WP even if src may have it and has pte marker installed. The warning is improper along with the comment. The right thing is to inherit the pte marker when needed, or keep the dst pte empty. A vague guess is this happened by an accident when there's the prior patch to introduce src/dst vma into this helper during the uffd-wp feature got developed and I probably messed up in the rebase, since if we replace dst_vma with src_vma the warning & comment it all makes sense too. Hugetlb did exactly the right here (copy_hugetlb_page_range()). Fix the general path.
