The below commit introduced a WARN when phy state is not in the states:
PHY_HALTED, PHY_READY and PHY_UP.
commit 744d23c71af3 ("net: phy: Warn about incorrect mdio_bus_phy_resume() state")
When cpsw resumes, there have port in PHY_NOLINK state, so the below
warning comes out. Set mac_managed_pm be true to tell mdio that the phy
resume/suspend is managed by the mac, to fix the following warning:

Subject: fat: Fix uninitialized field in nostale filehandles
Date: Mon, 5 Feb 2024 13:26:26 +0100
When fat_encode_fh_nostale() encodes file handle without a parent it
stores only first 10 bytes of the file handle. However the length of the
file handle must be a multiple of 4 so the file handle is actually 12
bytes long and the last two bytes remain uninitialized. This is not
great at we potentially leak uninitialized information with the handle
to userspace. Properly initialize the full handle length.

Subject: selftests/mm: uffd-unit-test check if huge page size is 0
Date: Mon, 5 Feb 2024 14:50:56 +0000
If HUGETLBFS is not enabled then the default_huge_page_size function will
return 0 and cause a divide by 0 error. Add a check to see if the huge page
size is 0 and skip the hugetlb tests if it is.

Subject: mm/damon/core: check apply interval in damon_do_apply_schemes()
Date: Mon, 5 Feb 2024 12:13:06 -0800
kdamond_apply_schemes() checks apply intervals of schemes and avoid
further applying any schemes if no scheme passed its apply interval.
However, the following schemes applying function, damon_do_apply_schemes()
iterates all schemes without the apply interval check. As a result, the
shortest apply interval is applied to all schemes. Fix the problem by
checking the apply interval in damon_do_apply_schemes().

This is combining a few unrelated one-liner fixes which have been
floating around internally into a single series. I'm not sure what is
the least amount of overhead for reviewers, this or a separate
submission per-patch? I guess it probably depends on personal
preference, but please let me know if there is a strong preference to
rather split these in the future.
Summary:
Patch1: Fixes an old issue which was hidden because 0 just so happens to
be the correct value.
Patch2: Fixes a corner case for flower offloading with bond ports
Patch3: Re-enables the 'NETDEV_XDP_ACT_REDIRECT', which was accidentally
disabled after a previous refactor.
Daniel Basilio (1):
nfp: use correct macro for LengthSelect in BAR config
