Right now there is no way to provide additional cflags/ldflags when
building tools/vm binaries. And using eg. make CFLAGS=<options> will
override the CFLAGS being set in the Makefile, making the build fail since
it requires the include of the ../lib dir (for libapi).
This change then allows you to specify:
CFLAGS=<options> LDFLAGS=<options> make V=1 -C tools/vm
And the options will be correctly appended as can be seen from the
make output.

Suppose memblock_alloc_range_nid() with highmem_start succeeds when
cma_declare_contiguous_nid is called with !fixed on a 32-bit system with
PHYS_ADDR_T_64BIT enabled with memblock.bottom_up == false.
But the next trial to memblock_alloc_range_nid() to allocate in [SIZE_4G,
limits) nullifies former successfully allocated addr and it retries
memblock_alloc_ragne_nid().
In this situation, the first successfully allocated address area is lost.
Change the order of allocation (SIZE_4G, high_memory and base) and check
whether the allocated succeeded to prevent potential memory loss.

Shadow_nodes is for shadow nodes reclaiming of workingset handling, it is
updated when page cache add or delete since long time ago workingset only
supported page cache. But when workingset supports anonymous page
detection, we missied updating shadow nodes for it. This caused that
shadow nodes of anonymous page will never be reclaimd by
scan_shadow_nodes() even they use much memory and system memory is tense.
So update shadow_nodes of anonymous page when swap cache is add or delete
by calling xas_set_update(..workingset_update_node).

Patch series "zsmalloc: make zspage chain size configurable".
Computers are bad at division. We currently decide the best zspage chain
size (max number of physical pages per-zspage) by looking at a `used
percentage` value. This is not enough as we lose precision during usage
percentage calculations For example, let's look at size class 208:
pages per zspage wasted bytes used%
1 144 96
2 80 99
3 16 99
4 160 99
Current algorithm will select 2 page per zspage configuration, as it's the
first one to reach 99%. However, 3 pages per zspage waste less memory.
Change algorithm and select zspage configuration that has lowest wasted
value.

Patch series "Some more filemap folio conversions".
Three more places which could easily be converted to folios. The third
one fixes a minor bug in readahead_expand(), but it's only a performance
bug and there are few users of readahead_expand(), so I don't think it's
worth backporting.
This patch (of 3):
Save a few calls to compound_head(). We specify exactly which page from
the folio to use by passing in start_pgoff, which means this will work for
a folio which is larger than PMD size. The rest of the VM isn't prepared
for that yet, but now this function is.

Convert function to use folios throughout. This is in preparation for the

Initially the function was checking if the previous page index is truly
the previous page i.e. 1 index behind the current page. To convert to
folios and maintain this check we need to make the check folio->index !=
prev + folio_nr_pages(previous folio) since we don't know how many pages
are in a folio.
At index i == 0 the check is guaranteed to succeed, so to workaround
indexing bounds we can simply ignore the check for that specific index.
This makes the initial assignment of prev trivial, so I removed that as
well.
Also modify a comment in commit_checkpoint for consistency.

Convert to use folios throughout. This function is in preparation to
remove find_get_pages_range_tag().
Also modify this function to write the whole batch one at a time, rather
than calling for a new set every single write.

Convert function to use folios throughout. This is in preparation for the
removal of find_get_pages_range_tag(). This change removes 8 calls to
compound_head(), and the function now supports large folios.

This is the equivalent of find_get_pages_range_tag(), except for folios
instead of pages.
One noteable difference is filemap_get_folios_tag() does not take in a
maximum pages argument. It instead tries to fill a folio batch and stops
either once full (15 folios) or reaching the end of the search range.
The new function supports large folios, the initial function did not since
all callers don't use large folios.
