256e4e4e83 mmc: sdhci-of-arasan: Skip Auto tuning for DDR50 mode in ZynqMP platform
ZynqMP platform does not perform auto tuning in DDR50 mode. Skip the
same while the card is operating in DDR50 mode.

25a916645e mmc: sdhci-of-arasan: Add "SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12" quirk.
Arasan controller supports AUTO CMD12, this patch adds
"SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12" quirk to enable auto cmd12
feature.
By using auto cmd12 we can also avoid following error message
"Got data interrupt even though no data operation in progress"

c0b4e411a9 mmc: sdhci-of-arasan: Modified SD default speed to 19MHz for ZynqMP
SD standard speed timing was met only at 19MHz and not 25 MHz, that's
why changing driver to 19MHz. The reason for this is when a level shifter
is used on the board, timing was met for standard speed only at 19MHz.
Since this level shifter is commonly required for high speed modes,
the driver is modified to use standard speed of 19Mhz.

c7b1850dfb hugetlb: don't pass page cache pages to restore_reserve_on_error
syzbot hit kernel BUG at fs/hugetlbfs/inode.c:532 as described in [1].
This BUG triggers if the HPageRestoreReserve flag is set on a page in
the page cache.  It should never be set, as the routine
huge_add_to_page_cache explicitly clears the flag after adding a page to
the cache.

The only code other than huge page allocation which sets the flag is
restore_reserve_on_error.  It will potentially set the flag in rare out
of memory conditions.  syzbot was injecting errors to cause memory
allocation errors which exercised this specific path.

The code in restore_reserve_on_error is doing the right thing.  However,
there are instances where pages in the page cache were being passed to
restore_reserve_on_error.  This is incorrect, as once a page goes into
the cache reservation information will not be modified for the page
until it is removed from the cache.  Error paths do not remove pages
from the cache, so even in the case of error, the page will remain in
the cache and no reservation adjustment is needed.

Modify routines that potentially call restore_reserve_on_error with a
page cache page to no longer do so.

Note on fixes tag: Prior to commit 846be08578 ("mm/hugetlb: expand
restore_reserve_on_error functionality") the routine would not process
page cache pages because the HPageRestoreReserve flag is not set on such
pages.  Therefore, this issue could not be trigggered.  The code added
by commit 846be08578 ("mm/hugetlb: expand restore_reserve_on_error
functionality") is needed and correct.  It exposed incorrect calls to
restore_reserve_on_error which is the root cause addressed by this
commit.

a7cb5d23ea kfence: fix is_kfence_address() for addresses below KFENCE_POOL_SIZE
Originally the addr != NULL check was meant to take care of the case
where __kfence_pool == NULL (KFENCE is disabled).  However, this does
not work for addresses where addr > 0 && addr < KFENCE_POOL_SIZE.

This can be the case on NULL-deref where addr > 0 && addr < PAGE_SIZE or
any other faulting access with addr < KFENCE_POOL_SIZE.  While the
kernel would likely crash, the stack traces and report might be
confusing due to double faults upon KFENCE's attempt to unprotect such
an address.

Fix it by just checking that __kfence_pool != NULL instead.

57f29762cd mm: vmscan: fix missing psi annotation for node_reclaim()
In a debugging session the other day, Rik noticed that node_reclaim()
was missing memstall annotations.  This means we'll miss pressure and
lost productivity resulting from reclaim on an overloaded local NUMA
node when vm.zone_reclaim_mode is enabled.

There haven't been any reports, but that's likely because
vm.zone_reclaim_mode hasn't been a commonly used feature recently, and
the intersection between such setups and psi users is probably nil.

But secondary memory such as CXL-connected DIMMS, persistent memory etc,
and the page demotion patches that handle them
(https://lore.kernel.org/lkml/20210401183216.443C4443@viggo.jf.intel.com/)
could soon make this a more common codepath again.

fcc00621d8 mm/hwpoison: retry with shake_page() for unhandlable pages
HWPoisonHandlable() sometimes returns false for typical user pages due
to races with average memory events like transfers over LRU lists.  This
causes failures in hwpoison handling.

There's retry code for such a case but does not work because the retry
loop reaches the retry limit too quickly before the page settles down to
handlable state.  Let get_any_page() call shake_page() to fix it.

f56ce412a5 mm: memcontrol: fix occasional OOMs due to proportional memory.low reclaim
We've noticed occasional OOM killing when memory.low settings are in
effect for cgroups.  This is unexpected and undesirable as memory.low is
supposed to express non-OOMing memory priorities between cgroups.

The reason for this is proportional memory.low reclaim.  When cgroups
are below their memory.low threshold, reclaim passes them over in the
first round, and then retries if it couldn't find pages anywhere else.
But when cgroups are slightly above their memory.low setting, page scan
force is scaled down and diminished in proportion to the overage, to the
point where it can cause reclaim to fail as well - only in that case we
currently don't retry, and instead trigger OOM.

To fix this, hook proportional reclaim into the same retry logic we have
in place for when cgroups are skipped entirely.  This way if reclaim
fails and some cgroups were scanned with diminished pressure, we'll try
another full-force cycle before giving up and OOMing.

47aef6010b mm/page_alloc: don't corrupt pcppage_migratetype
When placing pages on a pcp list, migratetype values over
MIGRATE_PCPTYPES get added to the MIGRATE_MOVABLE pcp list.

However, the actual migratetype is preserved in the page and should
not be changed to MIGRATE_MOVABLE or the page may end up on the wrong
free_list.

The impact is that HIGHATOMIC or CMA pages getting bulk freed from the
PCP lists could potentially end up on the wrong buddy list.  There are
various consequences but minimally NR_FREE_CMA_PAGES accounting could
get screwed up.

aa3e1ba32e riscv: Fix a number of free'd resources in init_resources()
Function init_resources() allocates a boot memory block to hold an array of
resources which it adds to iomem_resource. The array is filled in from its
end and the function then attempts to free any unused memory at the
beginning. The problem is that size of the unused memory is incorrectly
calculated and this can result in releasing memory which is in use by
active resources. Their data then gets corrupted later when the memory is
reused by a different part of the system.

Fix the size of the released memory to correctly match the number of unused
resource entries.

cd0a719fbd net: dpaa2-switch: disable the control interface on error path
Currently dpaa2_switch_takedown has a funny name and does not do the
opposite of dpaa2_switch_init, which makes probing fail when we need to
handle an -EPROBE_DEFER.

A sketch of what dpaa2_switch_init does:

	dpsw_open

	dpaa2_switch_detect_features

	dpsw_reset

	for (i = 0; i < ethsw->sw_attr.num_ifs; i++) {
		dpsw_if_disable

		dpsw_if_set_stp

		dpsw_vlan_remove_if_untagged

		dpsw_if_set_tci

		dpsw_vlan_remove_if
	}

	dpsw_vlan_remove

	alloc_ordered_workqueue

	dpsw_fdb_remove

	dpaa2_switch_ctrl_if_setup

When dpaa2_switch_takedown is called from the error path of
dpaa2_switch_probe(), the control interface, enabled by
dpaa2_switch_ctrl_if_setup from dpaa2_switch_init, remains enabled,
because dpaa2_switch_takedown does not call
dpaa2_switch_ctrl_if_teardown.

Since dpaa2_switch_probe might fail due to EPROBE_DEFER of a PHY, this
means that a second probe of the driver will happen with the control
interface directly enabled.

This will trigger a second error:

[   93.273528] fsl_dpaa2_switch dpsw.0: dpsw_ctrl_if_set_pools() failed
[   93.281966] fsl_dpaa2_switch dpsw.0: fsl_mc_driver_probe failed: -13
[   93.288323] fsl_dpaa2_switch: probe of dpsw.0 failed with error -13

Which if we investigate the /dev/dpaa2_mc_console log, we find out is
caused by:

[E, ctrl_if_set_pools:2211, DPMNG]  ctrl_if must be disabled

So make dpaa2_switch_takedown do the opposite of dpaa2_switch_init (in
reasonable limits, no reason to change STP state, re-add VLANs etc), and
rename it to something more conventional, like dpaa2_switch_teardown.
