For now, I'm operating under the assumption that we'll fully remove

We currently check for ret != 0 to indicate error, but '1' is a valid
return and just indicates that the allocation succeeded with a wrap.
Correct the check to be for < 0, like it was before the xarray
conversion.

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.

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.

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.

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.

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.

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.

Due to the change about how block layer detects congestion the
justification of commit 8fd2e0b505 ("mm: swap: check if swap backing
device is congested or not") doesn't stand anymore, so the commit could
be just reverted in order to solve the race reported by commit
2efa33fc7f ("mm/shmem: fix shmem_swapin() race with swapoff"), so the
fix commit could be just reverted as well.
And that fix is also kind of buggy as discussed by [1] and [2].

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.

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.

Disallow changes to HW MAC address and MAC filter from untrusted
VF, thanks to that ping is not lost if VF tries to change MAC.
Add a new field in iavf_mac_filter, to indicate whether there
was response from PF for given filter. Based on this field pass
or discard the filter.
If untrusted VF tried to change it's address, it's not changed.
Still filter was changed, because of that ping couldn't go through.

Without this patch, ATR does not work. Receive/transmit uses queue
selection based on SW DCB hashing method.
If traffic classes are not configured for PF, then use
netdev_pick_tx function for selecting queue for packet transmission.
Instead of calling i40e_swdcb_skb_tx_hash, call netdev_pick_tx,
which ensures that packet is transmitted/received from CPU that is
running the application.
Reproduction steps:
1. Load i40e driver
2. Map each MSI interrupt of i40e port for each CPU
3. Disable ntuple, enable ATR i.e.:
ethtool -K $interface ntuple off
ethtool --set-priv-flags $interface flow-director-atr
4. Run application that is generating traffic and is bound to a
single CPU, i.e.:
taskset -c 9 netperf -H 1.1.1.1 -t TCP_RR -l 10
5. Observe behavior:
Application's traffic should be restricted to the CPU provided in
taskset.

The commit 2e6b836312 ("ASoC: intel: atom: Fix reference to PCM
buffer address") changed the reference of PCM buffer address to
substream->runtime->dma_addr as the buffer address may change
dynamically. However, I forgot that the dma_addr field is still not
set up for the CONTINUOUS buffer type (that this driver uses) yet in
5.14 and earlier kernels, and it resulted in garbage I/O. The problem
will be fixed in 5.15, but we need to address it quickly for now.
The fix is to deduce the address again from the DMA pointer with
virt_to_phys(), but from the right one, substream->runtime->dma_area.
