The Beurer GL50 evo uses a Cygnal-manufactured CD-on-a-chip that only
accepts a subset of SCSI commands, and supports neither audio commands
nor generic packet commands.
Actually sending those commands bring the device to an unrecoverable
state that causes the device to hang and reset.

Reading the TOC only works if the device can play audio, otherwise
these commands fail (and possibly bring the device to an unhealthy
state.)
Similarly, cdrom_mmc3_profile() should only be called if the device
supports generic packet commands.

In attach_node_and_children memory is allocated for full_name via
kasprintf. If the condition of the 1st if is not met the function
returns early without freeing the memory. Add a kfree() to fix that.
This has been detected with kmemleak:

The only apparent reason for the PCI_MSI_IRQ_DOMAIN architecture
whitelist was that it requires msi.h. Now that msi.h is mandatory in
asm-generic/Kbuild, every arch should have at least the default version,
so remove the whitelist.
Built for all the architectures that play nice with make.cross, but not
boot tested anywhere.

When a driver enables MSI-X, msix_program_entries() reads the MSI-X Vector
Control register for each vector and saves it in desc->masked. Each
register is 32 bits and bit 0 is the actual Mask bit.
When we restored these registers during resume, we previously set the Mask
bit if *any* bit in desc->masked was set instead of when the Mask bit
itself was set:
pci_restore_state
pci_restore_msi_state
__pci_restore_msix_state
for_each_pci_msi_entry
msix_mask_irq(entry, entry->masked) <-- entire u32 word
__pci_msix_desc_mask_irq(desc, flag)
mask_bits = desc->masked & ~PCI_MSIX_ENTRY_CTRL_MASKBIT
if (flag) <-- testing entire u32, not just bit 0
mask_bits |= PCI_MSIX_ENTRY_CTRL_MASKBIT
writel(mask_bits, desc_addr + PCI_MSIX_ENTRY_VECTOR_CTRL)
This means that after resume, MSI-X vectors were masked when they shouldn't
be, which leads to timeouts like this:
nvme nvme0: I/O 978 QID 3 timeout, completion polled
On resume, set the Mask bit only when the saved Mask bit from suspend was
set.
This should remove the need for 19ea025e1d28 ("nvme: Add quirk for Kingston
NVME SSD running FW E8FK11.T").

27e20603c54b ("PCI/MSI: Move D0 check into pci_msi_check_device()")
moved the power state check into pci_msi_check_device(), which was
subsequently renamed to pci_msi_supported(). This didn't change the
behavior, since both callers checked the power state.
However, it doesn't fit the current "pci_msi_supported()" name, which
should return what the device is capable of, independent of the power
state.
Move the power state check back into the callers for readability. No
functional change intended.

If an error occurs on one of the ios used for creating an
association, the creating routine has error paths that are
invoked by the command failure and the error paths will free
up the controller resources created to that point.
But... the io was ultimately determined by an asynchronous
completion routine that detected the error and which
unconditionally invokes the error_recovery path which calls
delete_association. Delete association deletes all outstanding
io then tears down the controller resources. So the
create_association thread can be running in parallel with
the error_recovery thread. What was seen was the LLDD received
a call to delete a queue, causing the LLDD to do a free of a
resource, then the transport called the delete queue again
causing the driver to repeat the free call. The second free
routine corrupted the allocator. The transport shouldn't be
making the duplicate call, and the delete queue is just one
of the resources being freed.
To fix, it is realized that the create_association path is
completely serialized with one command at a time. So the
failed io completion will always be seen by the create_association
path and as of the failure, there are no ios to terminate and there
is no reason to be manipulating queue freeze states, etc.
The serialized condition stays true until the controller is
transitioned to the LIVE state. Thus the fix is to change the
error recovery path to check the controller state and only
invoke the teardown path if not already in the CONNECTING state.

We've seen a few devices that return different controller id's to
the Fabric Connect command vs the Identify(controller) command. It's
currently hard to identify this failure by existing error messages. It
comes across as a (re)connect attempt in the transport that fails with
a -22 (-EINVAL) status. The issue is compounded by older kernels not
having the controller id check or had the identify command overwrite the
fabrics controller id value before it checked. Both resulted in cases
where the devices appeared fine until more recent kernels.
Clarify the reject by adding an error message on controller id mismatches.

In nvme-fc: it's possible to have connected active controllers
and as no references are taken on the LLDD, the LLDD can be
unloaded. The controller would enter a reconnect state and as
long as the LLDD resumed within the reconnect timeout, the
controller would resume. But if a namespace on the controller
is the root device, allowing the driver to unload can be problematic.
To reload the driver, it may require new io to the boot device,
and as it's no longer connected we get into a catch-22 that
eventually fails, and the system locks up.
Fix this issue by taking a module reference for every connected
controller (which is what the core layer did to the transport
module). Reference is cleared when the controller is removed.

Be less pessimistic about estimated page table use for KFD. Most
allocations use 2MB pages and therefore need less VRAM for page
tables. This allows more VRAM to be used for applications especially
on large systems with many GPUs and hundreds of GB of system memory.
Example: 8 GPUs with 32GB VRAM each + 256GB system memory = 512GB
Old page table reservation per GPU: 1GB
New page table reservation per GPU: 32MB

nvme_loop_create_io_queues() preallocates a big buffer for the IO SGL based
on SG_CHUNK_SIZE.
Modern DMA engines are often capable of dealing with very big segments so
the SG_CHUNK_SIZE is often too big. SG_CHUNK_SIZE results in a static 4KB
SGL allocation per command.
If a controller has lots of deep queues, preallocation for the sg list can
consume substantial amounts of memory. For nvmet-loop, nr_hw_queues can be
128 and each queue's depth 128. This means the resulting preallocation
for the data SGL is 128*128*4K = 64MB per controller.
Switch to runtime allocation for SGL for lists longer than 2 entries. This
is the approach used by NVMe PCI so it should be reasonable for NVMeOF as
well. Runtime SGL allocation has always been the case for the legacy I/O
path so this is nothing new.

We didn't notice of a performance degradation, since for small IOs we'll
use the inline SG and for the bigger IOs the allocation of a bigger SGL
from slab is fast enough.

Removes the branching for edge-case where no SCSI device handler
exists. The __map_bio_fast() method was far too limited, by only
selecting a new pathgroup or path IFF there was a path failure, fix this
be eliminating it in favor of __map_bio(). __map_bio()'s extra SCSI
device handler specific MPATHF_PG_INIT_REQUIRED test is not in the fast
path anyway.
This change restores full path selector functionality for bio-based
configurations that don't haave a SCSI device handler. But it should be
noted that the path selectors do have an impact on performance for
certain networks that are extremely fast (and don't require frequent
switching).

With the recent 59bb47985c1d ("mm, sl[aou]b: guarantee natural
alignment for kmalloc(power-of-two)"), kzalloc() is able to allocate
a 4KB buffer that is guaranteed to be 4KB-aligned. Here the size and
alignment of hbus is important because hbus's field
retarget_msi_interrupt_params must not cross a 4KB page boundary.
Here we prefer kzalloc to get_zeroed_page(), because a buffer
allocated by the latter is not tracked and scanned by kmemleak, and
hence kmemleak reports the pointer contained in the hbus buffer
(i.e. the hpdev struct, which is created in new_pcichild_device() and
is tracked by hbus->children) as memory leak (false positive).
If the kernel doesn't have 59bb47985c1d, get_zeroed_page() *must* be
used to allocate the hbus buffer and we can avoid the kmemleak false
positive by using kmemleak_alloc() and kmemleak_free() to ask
kmemleak to track and scan the hbus buffer.

A VM can have multiple Hyper-V hbus. It's incorrect to set the global
variable 'pci_protocol_version' when *every* hbus is initialized in
hv_pci_protocol_negotiation(). This is not an issue in practice since
every hbus should have the same value of hbus->protocol_version, but
we should make the variable per-hbus, so in case we have busses
with different protocol versions, the driver can still work correctly.

Add suspend() and resume() functions so that Hyper-V virtual PCI devices
are handled properly when the VM hibernates and resumes from
hibernation.
Note that the suspend() function must make sure there are no pending
work items before calling vmbus_close(), since it runs in a process
context as a callback in dpm_suspend(). When it starts to run, the
channel callback hv_pci_onchannelcallback(), which runs in a tasklet
context, can be still running concurrently and scheduling new work items
onto hbus->wq in hv_pci_devices_present() and hv_pci_eject_device(), and
the work item handlers can access the vmbus channel, which can be being
closed by hv_pci_suspend(), e.g. the work item handler
pci_devices_present_work() -> new_pcichild_device() writes to the vmbus
channel.
To eliminate the race, hv_pci_suspend() disables the channel callback
tasklet, sets hbus->state to hv_pcibus_removing, and re-enables the
tasklet. This way, when hv_pci_suspend() proceeds, it knows that no new
work item can be scheduled, and then it flushes hbus->wq and safely
closes the vmbus channel.

In order to avoid some nasty mutex inversions, commit 09c5ab384f6f
("drm/i915: Keep rings pinned while the context is active") allowed the
intel_ring unpinning to be run concurrently with the next context
pinning it. Thus each step in intel_ring_unpin() needed to be atomic and
ordered in a nice onion with intel_ring_pin() so that the lifetimes
overlapped and were always safe.
Sadly, a few steps in intel_ring_unpin() were overlooked, such as
closing the read/write pointers of the ring and discarding the
intel_ring.vaddr, as these steps were not serialised with
intel_ring_pin() and so could leave the ring in disarray.
Fixes: 09c5ab384f6f ("drm/i915: Keep rings pinned while the context is active")
