ASoC: soc.h: fixup return timing for snd_soc_fixup_dai_links_platform_name()
Current snd_soc_fixup_dai_links_platform_name() creates name first (A),
and checks setup target pointer (B), and set it (C).
We should check target pointer first IMO.
This patch exchange the order to (B) -> (A) -> (C).

	int snd_soc_fixup_dai_links_platform_name(...)
	{
		...
		/* set platform name for each dailink */
		for_each_card_prelinks(card, i, dai_link) {
(A)			name = devm_kstrdup(...);
			if (!name)
				return -ENOMEM;

(B)			if (!dai_link->platforms)
				return -EINVAL;

			/* only single platform is supported for now */
(C)			dai_link->platforms->name = name;
		}

		return 0;

ASoC: imx-pcm-rpmsg: Add platform driver for audio base on rpmsg
Platform driver based on rpmsg is the interface for sending and
receiving rpmsg to and from M core. It will tell the Cortex-M core
sound format/rate/channel, where is the data buffer, where is
the period size, when to start, when to stop and when suspend
or resume happen, each this behavior there is defined rpmsg
command.

Especially we designed the low power audio case, that is to
allocate a large buffer and fill the data, then Cortex-A core can go
to sleep mode, Cortex-M core continue to play the sound, when the
buffer is consumed, Cortex-M core will trigger the Cortex-A core to
wake up.

Rich Wiley 20109a859a arm64: kernel: disable CNP on Carmel
On NVIDIA Carmel cores, CNP behaves differently than it does on standard
ARM cores. On Carmel, if two cores have CNP enabled and share an L2 TLB
entry created by core0 for a specific ASID, a non-shareable TLBI from
core1 may still see the shared entry. On standard ARM cores, that TLBI
will invalidate the shared entry as well.

This causes issues with patchsets that attempt to do local TLBIs based
on cpumasks instead of broadcast TLBIs. Avoid these issues by disabling
CNP support for NVIDIA Carmel cores.

Martin Wilck 077ce028b8 scsi: target: pscsi: Avoid OOM in pscsi_map_sg()
pscsi_map_sg() uses the variable nr_pages as a hint for bio_kmalloc() how
many vector elements to allocate. If nr_pages is < BIO_MAX_PAGES, it will
be reset to 0 after successful allocation of the bio.

If bio_add_pc_page() fails later for whatever reason, pscsi_map_sg() tries
to allocate another bio, passing nr_vecs = 0. This causes bio_add_pc_page()
to fail immediately in the next call. pci_map_sg() continues to allocate
zero-length bios until memory is exhausted and the kernel crashes with
OOM. This can be easily observed by exporting a SATA DVD drive via pscsi.
The target crashes as soon as the client tries to access the DVD LUN. In
the case I analyzed, bio_add_pc_page() would fail because the DVD device's
max_sectors_kb (128) was exceeded.

Avoid this by simply not resetting nr_pages to 0 after allocating the
bio. This way, the client receives an I/O error when it tries to send
requests exceeding the devices max_sectors_kb, and eventually gets it
right. The client must still limit max_sectors_kb e.g. by an udev rule if
(like in my case) the driver doesn't report valid block limits, otherwise
it encounters I/O errors.

Bart Van Assche 39c0c8553b scsi: Revert "qla2xxx: Make sure that aborted commands are freed"
Calling vha->hw->tgt.tgt_ops->free_cmd() from qlt_xmit_response() is wrong
since the command for which a response is sent must remain valid until the
SCSI target core calls .release_cmd(). It has been observed that the
following scenario triggers a kernel crash:

 - qlt_xmit_response() calls qlt_check_reserve_free_req()

 - qlt_check_reserve_free_req() returns -EAGAIN

 - qlt_xmit_response() calls vha->hw->tgt.tgt_ops->free_cmd(cmd)

 - transport_handle_queue_full() tries to retransmit the response

Fix this crash by reverting the patch that introduced it.

Tyrel Datwyler 62fc266148 scsi: ibmvfc: Make ibmvfc_wait_for_ops() MQ aware
During MQ enablement of the ibmvfc driver ibmvfc_wait_for_ops() was
missed. This function is responsible for waiting on commands to complete
that match a certain criteria such as LUN or cancel key. The implementation
as is only scans the CRQ for events ignoring any sub-queues and as a result
will exit successfully without doing anything when operating in MQ
channelized mode.

Check the MQ and channel use flags to determine which queues are
applicable, and scan each queue accordingly. Note in MQ mode SCSI commands
are only issued down sub-queues and the CRQ is only used for driver
specific management commands. As such the CRQ events are ignored when
operating in MQ mode with channels.

Tyrel Datwyler 8b1c9b2025 scsi: ibmvfc: Fix potential race in ibmvfc_wait_for_ops()
For various EH activities the ibmvfc driver uses ibmvfc_wait_for_ops() to
wait for the completion of commands that match a given criteria be it
cancel key, or specific LUN. With recent changes commands are completed
outside the lock in bulk by removing them from the sent list and adding
them to a private completion list. This introduces a potential race in
ibmvfc_wait_for_ops() since the criteria for a command to be outstanding is
no longer simply being on the sent list, but instead not being on the free
list.

Avoid this race by scanning the entire command event pool and checking that
any matching command that ibmvfc needs to wait on is not already on the
free list.

Lyude Paul d3999c1f7b drm/nouveau/kms/nve4-nv108: Limit cursors to 128x128
While Kepler does technically support 256x256 cursors, it turns out that
Kepler actually has some additional requirements for scanout surfaces that
we're not enforcing correctly, which aren't present on Maxwell and later.
Cursor surfaces must always use small pages (4K), and overlay surfaces must
always use large pages (128K).

Fixing this correctly though will take a bit more work: as we'll need to
add some code in prepare_fb() to move cursor FBs in large pages to small
pages, and vice-versa for overlay FBs. So until we have the time to do
that, just limit cursor surfaces to 128x128 - a size small enough to always
default to small pages.

This means small ovlys are still broken on Kepler, but it is extremely
unlikely anyone cares about those anyway :).

Roger Pau Monne af44a387e7 Revert "xen: fix p2m size in dom0 for disabled memory hotplug case"
This partially reverts commit 882213990d ("xen: fix p2m size in dom0
for disabled memory hotplug case")

There's no need to special case XEN_UNPOPULATED_ALLOC anymore in order
to correctly size the p2m. The generic memory hotplug option has
already been tied together with the Xen hotplug limit, so enabling
memory hotplug should already trigger a properly sized p2m on Xen PV.

Note that XEN_UNPOPULATED_ALLOC depends on ZONE_DEVICE which pulls in
MEMORY_HOTPLUG.

Roger Pau Monne 2b514ec727 xen/x86: make XEN_BALLOON_MEMORY_HOTPLUG_LIMIT depend on MEMORY_HOTPLUG
The Xen memory hotplug limit should depend on the memory hotplug
generic option, rather than the Xen balloon configuration. It's
possible to have a kernel with generic memory hotplug enabled, but
without Xen balloon enabled, at which point memory hotplug won't work
correctly due to the size limitation of the p2m.

Rename the option to XEN_MEMORY_HOTPLUG_LIMIT since it's no longer
tied to ballooning.

Merge series "MFD/extcon/ASoC: Rework arizona codec jack-detect support" from Hans de Goede <hdegoede@redhat.com>:
Hi All,

Here is v4 of my series to rework the arizona codec jack-detect support
to use the snd_soc_jack helpers instead of direct extcon reporting.

As discussed before here is a resend rebased on 5.12-rc2, making sure that
all patches this depends on are in place.

Lee, can you pick-up patches 1-6 through the MFD tree and then send a
pull-req to Mark so that Mark can merge the Asoc parts throught the ASoC
tree ?

Patches 2-6 touch drivers/extcon, these all have an Ack from Chanwoo Choi
for merging these through the MFD tree.

Here is some more generic info on this series from the previous
cover-letter:

This is done by reworking the extcon driver into an arizona-jackdet
library and then modifying the codec drivers to use that directly,
replacing the old separate extcon child-devices and extcon-driver.

This brings the arizona-codec jack-detect handling inline with how
all other ASoC codec driver do this. This was developed and tested on
a Lenovo Yoga Tablet 1051L with a WM5102 codec.

This was also tested by Charles Keepax, one of the Cirrus Codec folks.

Regards,

Hans

ASoC: arizona-jack: Use snd_soc_jack to report jack events
Use the snd_soc_jack code to report jack events, instead of using extcon
for reporting the cable-type + an input_dev for reporting the button
presses.

The snd_soc_jack code will report the cable-type through both input_dev
events and through ALSA controls and the button-presses through input_dev
events.

Note that this means that when the codec drivers are moved over to use
the new arizona-jack.c library code instead of having a separate MFD
extcon cell with the extcon-arizona.c driver, we will no longer report
extcon events to userspace for cable-type changes. This should not be
a problem since "standard" Linux distro userspace does not (and has
never) used the extcon class interface for this. Android does have
support for the extcon class interface, but that was introduced in
the same release as support for input_dev cable-type events, so this
should not be a problem for Android either.

Note this also reduces ARIZONA_MAX_MICD_RANGE from 8 to 6, this is
ok to do since this info is always provided through pdata (or defaults)
and cannot be overridden from devicetree. All in-kernel users of the
pdata (and the fallback defaults) define 6 or less buttons/ranges.

ASoC: arizona-jack: convert into a helper library for codec drivers
Convert the arizona extcon driver into a helper library for direct use
from the arizona codec-drivers, rather then being bound to a separate
MFD cell.

Note the probe (and remove) sequence is split into 2 parts:

1. The arizona_jack_codec_dev_probe() function inits a bunch of
jack-detect specific variables in struct arizona_priv and tries to get
a number of resources where getting them may fail with -EPROBE_DEFER.

2. Then once the machine driver has create a snd_sock_jack through
snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on
the codec component, which will call the new arizona_jack_set_jack(),
which sets up jack-detection and requests the IRQs.

This split is necessary, because the IRQ handlers need access to the
arizona->dapm pointer and the snd_sock_jack which are not available
when the codec-driver's probe function runs.

Note this requires that machine-drivers for codecs which are converted
to use the new helper functions from arizona-jack.c are modified to
create a snd_soc_jack through snd_soc_card_jack_new() and register
this jack with the codec through snd_soc_component_set_jack().

ASoC: arizona-jack: Use arizona->dev for runtime-pm
Drivers for MFD child-devices such as the arizona codec drivers
and the arizona-extcon driver can choose to either make
runtime_pm_get/_put calls on their own child-device, which will
then be propagated to their parent; or they can make them directly
on their MFD parent-device.

The arizona-extcon code was using runtime_pm_get/_put calls on
its own child-device where as the codec drivers are using
runtime_pm_get/_put calls on their parent.

The arizona-extcon MFD cell/child-device has been removed and this
commit is part of refactoring the arizona-extcon code into a library
to be used directly from the codec drivers.

Specifically this commit moves the code over to make
runtime_pm_get/_put calls on the parent device (on arizona->dev)
bringing the code inline with how the codec drivers do this.

Note this also removes the pm_runtime_enable/_disable calls
as pm_runtime support has already been enabled on the parent-device
by the arizona MFD driver.

This is part of a patch series converting the arizona extcon driver into
a helper library for letting the arizona codec-drivers directly report
jack state through the standard sound/soc/soc-jack.c functions.

Johannes Thumshirn 7de55b7d6f block: support zone append bvecs
Christoph reported that we'll likely trigger the WARN_ON_ONCE() checking
that we're not submitting a bvec with REQ_OP_ZONE_APPEND in
bio_iov_iter_get_pages() some time ago using zoned btrfs, but I couldn't
reproduce it back then.

Now Naohiro was able to trigger the bug as well with xfstests generic/095
on a zoned btrfs.

There is nothing that prevents bvec submissions via REQ_OP_ZONE_APPEND if
the hardware's zone append limit is met.

Pull cachefiles and afs fixes from David Howells:
 "Fixes from Matthew Wilcox for page waiting-related issues in
  cachefiles and afs as extracted from his folio series[1]:

   - In cachefiles, remove the use of the wait_bit_key struct to access
     something that's actually in wait_page_key format. The proper
     struct is now available in the header, so that should be used
     instead.

   - Add a proper wait function for waiting killably on the page
     writeback flag. This includes a recent bugfix[2] that's not in the
     afs code.

   - In afs, use the function added in (2) rather than using
     wait_on_page_bit_killable() which doesn't provide the
     aforementioned bugfix"

Christian Brauner bf1c82a538 cachefiles: do not yet allow on idmapped mounts
Based on discussions (e.g. in [1]) my understanding of cachefiles and
the cachefiles userspace daemon is that it creates a cache on a local
filesystem (e.g. ext4, xfs etc.) for a network filesystem. The way this
is done is by writing "bind" to /dev/cachefiles and pointing it to the
directory to use as the cache.

Currently this directory can technically also be an idmapped mount but
cachefiles aren't yet fully aware of such mounts and thus don't take the
idmapping into account when creating cache entries. This could leave
users confused as the ownership of the files wouldn't match to what they
expressed in the idmapping. Block cache files on idmapped mounts until
the fscache rework is done and we have ported it to support idmapped
mounts.

Vegard Nossum 25928deeb1 ACPICA: Always create namespace nodes using acpi_ns_create_node()
ACPICA commit 29da9a2a3f5b2c60420893e5c6309a0586d7a329

ACPI is allocating an object using kmalloc(), but then frees it
using kmem_cache_free(<"Acpi-Namespace" kmem_cache>).

This is wrong and can lead to boot failures manifesting like this:

Thomas Richter eb8f998bbc perf test: Remove now useless failing sub test "BPF relocation checker"
For some time now the 'perf test 42: BPF filter' returns an error on bpf
relocation subtest, at least on x86 and s390. This is caused by

  d859900c4c ("bpf, libbpf: support global data/bss/rodata sections")

which introduces support for global variables in eBPF programs.

Perf test 42.4 checks that the eBPF relocation fails when the eBPF program
contains a global variable. It returns OK when the eBPF program
could not be loaded and FAILED otherwise.

With above commit the test logic for the eBPF relocation is obsolete.
The loading of the eBPF now succeeds and the test always shows FAILED.

This patch removes the sub test completely.
Also a lot of eBPF program testing is done in the eBPF test suite,
it also contains tests for global variables.

Output before:
 42: BPF filter                          :
 42.1: Basic BPF filtering               : Ok
 42.2: BPF pinning                       : Ok
 42.3: BPF prologue generation           : Ok
 42.4: BPF relocation checker            : Failed
 #

Output after:
 # ./perf test -F 42
 42: BPF filter                          :
 42.1: Basic BPF filtering               : Ok
