The implementation appears not to support pause modes on anything
but RGMII, RGMII_TXID, MII and REVMII interface modes. Let phylink
know that detail.
(This may not be correct; particularly see the FIXMEs in this patch.)

DSA assumes that a bridge which has vlan filtering disabled is not
vlan aware, and ignores all vlan configuration. However, the kernel
software bridge code allows configuration in this state.
This causes the kernel's idea of the bridge vlan state and the
hardware state to disagree, so "bridge vlan show" indicates a correct
configuration but the hardware lacks all configuration. Even worse,
enabling vlan filtering on a DSA bridge immediately blocks all traffic
which, given the output of "bridge vlan show", is very confusing.
Provide an option that drivers can set to indicate they want to receive
vlan configuration even when vlan filtering is disabled. This is safe
for Marvell DSA bridges, which do not look up ingress traffic in the
VTU if the port is in 8021Q disabled state. Whether this change is
suitable for all DSA bridges is not known.

phy_error() is called from phy_interrupt() or phy_state_machine(), and
uses WARN_ON() to print a backtrace. The backtrace is not useful when
reporting a PHY error.
However, a system may contain multiple ethernet PHYs, and phy_error()
gives no clue which one caused the problem.
Replace WARN_ON() with a call to phydev_err() so that we can see which
PHY had an error, and also inform the user that we are halting the PHY.

Configure the Macchiatobin 10G PHY LED modes to correct their polarity.
We keep the existing LED behaviours, but switch their polarity to
reflect how they are connected. Tweak the LED modes as well to be:
left: off = no link
solid green = RJ45 link up (not SFP+ cage)
flash green = traffic
right: off = no link
solid green = 10G
solid yellow = 1G
flash green = 100M
flash yellow = 10M

Add support for configuring the LEDs. Macchiatobin has an oddity in
that the left LED goes out when the cable is connected, and flashes

ground. Add support for configuring the LED modes and polarities.

There are several places which open code comparing PHY IDs. Provide a
couple of helpers to assist with this, using a slightly simpler test
than the original:
- phy_id_compare() compares two arbitary PHY IDs and a mask of the
significant bits in the ID.
- phydev_id_compare() compares the bound phydev with the specified
PHY ID, using the bound driver's mask.
Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

The at803x driver contains a function, at803x_match_phy_id(), which
tests whether the PHY ID matches the value passed, comparing phy_id
with phydev->phy_id and testing all bits that have a "one" in the
mask, phydev->drv->phy_id_mask.
This is the same test that is used to match the driver, with phy_id
replaced with the driver specified ID, phydev->drv->phy_id.
Hence, we already know the value of the bits being tested if we look
at phydev->drv->phy_id directly, and we do not require a complicated
test to check them. Test directly against phydev->drv->phy_id instead.

If we intend to use PCS operations, mac_pcs_get_state() will not be
implemented, so will be NULL. If we also intend to register the PCS
operations in mac_prepare() or mac_config(), then this leads to an
attempt to call NULL function pointer during phylink_start(). Avoid
this.

Reason: A lot of the ptp drivers - which implement hardware time stamping - need
specific fields such as the sequence id from the ptp v2 header. Currently all
drivers implement that themselves.

header.

The SGMII PCS PHY needs to be updated with the link configuration in
the mac_link_up() call rather than in mac_config(). However,
mtk_sgmii_setup_mode_force() programs the SGMII block during
mac_config() when using 802.3z interface modes with the link
configuration.
Split that functionality from mtk_sgmii_setup_mode_force(), moving it
to a new mtk_sgmii_link_up() function, and call it from mac_link_up().
This does not look correct to me: 802.3z modes operate at a fixed
speed. The contents of mtk_sgmii_link_up() look more appropriate for
SGMII mode, but the original code definitely did not call
mtk_sgmii_setup_mode_force() for SGMII mode but only 802.3z mode.

by khugepaged
When memory is hotplug added or removed the min_free_kbytes should be
recalculated based on what is expected by khugepaged. Currently after
hotplug, min_free_kbytes will be set to a lower default and higher
default set when THP enabled is lost.
This change restores min_free_kbytes as expected for THP consumers.

There have been elusive reports of filemap_fault() hitting its
VM_BUG_ON_PAGE(page_to_pgoff(page) != offset, page) on kernels built
with CONFIG_READ_ONLY_THP_FOR_FS=y.
Suren has hit it on a kernel with CONFIG_READ_ONLY_THP_FOR_FS=y and
CONFIG_NUMA is not set: and he has analyzed it down to how khugepaged
without NUMA reuses the same huge page after collapse_file() failed
(whereas NUMA targets its allocation to the respective node each time).
And most of us were usually testing with CONFIG_NUMA=y kernels.
collapse_file(old start)
new_page = khugepaged_alloc_page(hpage)
__SetPageLocked(new_page)
new_page->index = start // hpage->index=old offset
new_page->mapping = mapping
xas_store(&xas, new_page)
filemap_fault
page = find_get_page(mapping, offset)
// if offset falls inside hpage then
// compound_head(page) == hpage
lock_page_maybe_drop_mmap()
__lock_page(page)
// collapse fails
xas_store(&xas, old page)
new_page->mapping = NULL
unlock_page(new_page)
collapse_file(new start)
new_page = khugepaged_alloc_page(hpage)
__SetPageLocked(new_page)
new_page->index = start // hpage->index=new offset
new_page->mapping = mapping // mapping becomes valid again
// since compound_head(page) == hpage
// page_to_pgoff(page) got changed
VM_BUG_ON_PAGE(page_to_pgoff(page) != offset)
An initial patch replaced __SetPageLocked() by lock_page(), which did
fix the race which Suren illustrates above. But testing showed that it's
not good enough: if the racing task's __lock_page() gets delayed long
after its find_get_page(), then it may follow collapse_file(new start)'s
successful final unlock_page(), and crash on the same VM_BUG_ON_PAGE.
It could be fixed by relaxing filemap_fault()'s VM_BUG_ON_PAGE to a
check and retry (as is done for mapping), with similar relaxations in
find_lock_entry() and pagecache_get_page(): but it's not obvious what
else might get caught out; and khugepaged non-NUMA appears to be unique
in exposing a page to page cache, then revoking, without going through
a full cycle of freeing before reuse.
Instead, non-NUMA khugepaged_prealloc_page() release the old page
if anyone else has a reference to it (1% of cases when I tested).
Although never reported on huge tmpfs, I believe its find_lock_entry()
has been at similar risk; but huge tmpfs does not rely on khugepaged
for its normal working nearly so much as READ_ONLY_THP_FOR_FS does.

Pull RISC-V fixes from Palmer Dabbelt:
"Two fixes this week:
- A fix to actually reserve the device tree's memory. Without this
the device tree can be overwritten on systems that don't otherwise
reserve it. This issue should only manifest on !MMU systems.
- A workaround for a BUG() that triggers when the memory that
originally contained initdata is freed and later repurposed. This
triggers a BUG() on builds that had HARDENED_USERCOPY enabled"
