I noticed that the logic in the fadvise64_64 syscall is incorrect for
partial pages.  While first page of the region is correctly skipped if
it is partial, the last page of the region is mistakenly discarded.
This leads to problems for applications that read data in
non-page-aligned chunks discarding already processed data between the
reads.

A somewhat misguided application that does something like write(XX bytes
(non-page-alligned)); drop the data it just wrote; repeat gets a
significant penalty in performance as a result.

Tejun submitted commit 23d11a58

 ("workqueue: skip flush dependency
checks for legacy workqueues") for the legacy create*_workqueue()
interface.

But some workq created by alloc_workqueue still reports warning on
memory reclaim, e.g nvme_workq with flag WQ_MEM_RECLAIM set:

    workqueue: WQ_MEM_RECLAIM nvme:nvme_reset_work is flushing !WQ_MEM_RECLAIM events:lru_add_drain_per_cpu
    ------------[ cut here ]------------
    WARNING: CPU: 0 PID: 6 at SoC/linux/kernel/workqueue.c:2448 check_flush_dependency+0xb4/0x10c

That's because lru_add_drain_all() will schedule the drain work on
system_wq, whose flag is set to 0, !WQ_MEM_RECLAIM.

Introduce a dedicated WQ_MEM_RECLAIM workqueue to do
lru_add_drain_all(), aiding in getting memory freed.

Christian Borntraeger reported a kernel panic after corrupt page counts,
and it turned out to be a regression introduced with commit aa88b68c


("thp: keep huge zero page pinned until tlb flush"), at least on s390.

put_huge_zero_page() was moved over from zap_huge_pmd() to
release_pages(), and it was replaced by tlb_remove_page().  However,
release_pages() might not always be triggered by (the arch-specific)
tlb_remove_page().

On s390 we call free_page_and_swap_cache() from tlb_remove_page(), and
not tlb_flush_mmu() -> free_pages_and_swap_cache() like the generic
version, because we don't use the MMU-gather logic.  Although both
functions have very similar names, they are doing very unsimilar things,
in particular free_page_xxx is just doing a put_page(), while
free_pages_xxx calls release_pages().

This of course results in very harmful put_page()s on the huge zero
page, on architectures where tlb_remove_page() is implemented in this
way.  It seems to affect only s390 and sh, but sh doesn't have THP
support, so the problem (currently) probably only exists on s390.

The following quick hack fixed the issue:

When creating a private mapping of a hugetlbfs file, it is possible to
unmap pages via ftruncate or fallocate hole punch.  If subsequent faults
repopulate these mappings, the reserve counts will go negative.  This is
because the code currently assumes all faults to private mappings will
consume reserves.  The problem can be recreated as follows:

 - mmap(MAP_PRIVATE) a file in hugetlbfs filesystem
 - write fault in pages in the mapping
 - fallocate(FALLOC_FL_PUNCH_HOLE) some pages in the mapping
 - write fault in pages in the hole

This will result in negative huge page reserve counts and negative
subpool usage counts for the hugetlbfs.  Note that this can also be
recreated with ftruncate, but fallocate is more straight forward.

This patch modifies the routines vma_needs_reserves and vma_has_reserves
to examine the reserve map associated with private mappings similar to
that for shared mappings.  However, the reserve map semantics for
private and shared mappings are very different.  This results in subtly
different code that is explained in the comments.
