According to the tool fortify, phy_up_v3_hw() returns signed value, while
it should return an unsigned value.
So change variable "res" from int to irq_return_t.

On 32-bit architectures, we see a warning when %ld is used to print a
size_t:

In "XFS over network block device" scenario XFS can create IO requests with
slab-based XFS metadata. During processing such requests tcp_sendpage() can
merge skb fragments with neighbour slab objects.
If receiving side is located on the same host tcp_recvmsg() can trigger
BUG_ON in hardening check and crash the host with following message:
usercopy: kernel memory exposure attempt detected
from XXXXXXXX (kmalloc-512) (1024 bytes)
This patch redirect such requests from sednpage to sendmsg path. The
problem is similar to one described in recent commit 7e241f647dc7
("libceph: fall back to sendmsg for slab pages")

Depending on the target architecture and configuration, both phys_addr_t
and dma_addr_t may be smaller than 'long long', so we get a warning when
printing either of them using the %llx format string:
drivers/scsi/qla2xxx/qla_iocb.c: In function 'qla24xx_walk_and_build_prot_sglist':
drivers/scsi/qla2xxx/qla_iocb.c:1140:46: error: format '%llx' expects argument of type 'long long unsigned int', but argument 6 has type 'dma_addr_t' {aka 'unsigned int'} [-Werror=format=]

"%s: sg[%x] (phys=%llx sglen=%x) ldma_sg_len: %x dif_bundl_len: %x ldma_needed: %x\n",
~~~^
There are special %pad and %pap format strings in Linux that we could use
here, but since the driver already does 64-bit arithmetic on the values,
using a plain 'u64' seems more consistent here.
Note: A possible related issue may be that the driver possibly checks the
wrong kind of overflow: when an IOMMU is in use, buffers that cross a
32-bit boundary in physical addresses would still be mapped into dma
addresses within the low 4GB space, so I suspect that we actually want to
check sg_dma_address() instead of sg_phys() here.

The outer routine lpfc_sli_issue_iocb(), which decomposes into the
SLI3 (s3) or SLI4 (s4) subroutines takes out the locks. For s3, it takes
out the hbalock. For s4, it takes out the ring_lock. The lockdep check in
the s3 and s4 subroutines both check hbalock, which is incorrect for s4.

megaraid_sas takes 1+ seconds to load while waiting for firmware:
[2.822603] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[3.871003] megaraid_sas 0000:03:00.0: FW now in Ready state
This is due to the following loop in megasas_transition_to_ready(), which
waits a minimum of 1 second, even though the FW becomes ready in tens of
millisecs:
/*
* The cur_state should not last for more than max_wait secs
*/
for (i = 0; i < max_wait; i++) {
...
msleep(1000);
...
dev_info(&instance->pdev->dev, "FW now in Ready state\n");
This is a regression, caused by a change of the msleep granularity from 1
to 1000 due to concern about waiting too long on systems with coarse
jiffies.
To fix, increase iterations and use msleep(20), which results in:
[2.670627] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[2.739386] megaraid_sas 0000:03:00.0: FW now in Ready state

The pm8xxx_get_channel() implementation is unclear, and causes gcc to
suddenly generate odd warnings. The trigger for the warning (at least
for me) was the entirely unrelated commit 79a4e91d1bb2 ("device.h: Add
__cold to dev_<level> logging functions"), which apparently changes gcc
code generation in the caller function enough to cause this:
drivers/iio/adc/qcom-pm8xxx-xoadc.c: In function ‘pm8xxx_xoadc_probe’:
drivers/iio/adc/qcom-pm8xxx-xoadc.c:633:8: warning: ‘ch’ may be used uninitialized in this function [-Wmaybe-uninitialized]
ret = pm8xxx_read_channel_rsv(adc, ch, AMUX_RSV4,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
&read_nomux_rsv4, true);
~~~~~~~~~~~~~~~~~~~~~~~
drivers/iio/adc/qcom-pm8xxx-xoadc.c:426:27: note: ‘ch’ was declared here
struct pm8xxx_chan_info *ch;
^~
because gcc for some reason then isn't able to see that the termination
condition for the "for( )" loop in that function is also the condition
for returning NULL.
So it's not _actually_ uninitialized, but the function is admittedly
just unnecessarily oddly written.
Simplify and clarify the function, making gcc also see that it always
returns a valid initialized value.

those will disable/enable preemption.

sure they happen outside of kernel_fpu_begin/end.

When disabling and removing a receive context, it is possible for an
asynchronous event (i.e IRQ) to occur. Because of this, there is a race
between cleaning up the context, and the context being used by the
asynchronous event.
cpu 0 (context cleanup)
rc->ref_count-- (ref_count == 0)
hfi1_rcd_free()
cpu 1 (IRQ (with rcd index))
rcd_get_by_index()
lock
ref_count+++ <-- reference count race (WARNING)
return rcd
unlock
cpu 0
hfi1_free_ctxtdata() <-- incorrect free location
lock
remove rcd from array
unlock
free rcd
This race will cause the following WARNING trace:

The previous attempted bug fix overlooked the fact that
ib_umem_odp_map_dma_single_page() was doing a put_page() upon hitting an
error. So there was not really a bug there.
Therefore, this reverts the off-by-one change, but keeps the change to use
release_pages() in the error path.

Pull ARM new SoC family support from Arnd Bergmann:
"Two new SoC families are added this time.
Sugaya Taichi submitted support for the Milbeaut SoC family from
Socionext and explains:
"SC2000 is a SoC of the Milbeaut series. equipped with a DSP
optimized for computer vision. It also features advanced
functionalities such as 360-degree, real-time spherical stitching
with multi cameras, image stabilization for without mechanical
gimbals, and rolling shutter correction. More detail is below:
https://www.socionext.com/en/products/assp/milbeaut/SC2000.html"
Interestingly, this one has a history dating back to older chips made
by Socionext and previously Matsushita/Panasonic based on their own
mn10300 CPU architecture that was removed from the kernel last year.
Manivannan Sadhasivam adds support for another SoC family, this is the
Bitmain BM1880 chip used in the Sophon Edge TPU developer board.
The chip is intended for Deep Learning applications, and comes with
dual-core Arm Cortex-A53 to run Linux as well as a RISC-V
microcontroller core to control the tensor unit. For the moment, the
TPU is not accessible in mainline Linux, so we treat it as a generic
Arm SoC.

The virtio scsi spec defines struct virtio_scsi_ctrl_tmf as a set of
device-readable records and a single device-writable response entry:
struct virtio_scsi_ctrl_tmf
{
// Device-readable part
le32 type;
le32 subtype;
u8 lun[8];
le64 id;
// Device-writable part
u8 response;
}
The above should be organised as two descriptor entries (or potentially
more if using VIRTIO_F_ANY_LAYOUT), but without any extra data after "le64
id" or after "u8 response".
The Linux driver doesn't respect that, with virtscsi_abort() and
virtscsi_device_reset() setting cmd->sc before calling virtscsi_tmf(). It
results in the original scsi command payload (or writable buffers) added to
the tmf.
This fixes the problem by leaving cmd->sc zeroed out, which makes
virtscsi_kick_cmd() add the tmf to the control vq without any payload.

When the HARDWARE_ERROR/0x3e/0x1 case is triggered, the logical volume
is offlined. When reading the kernel log, the reason why the device
got offlined isn't reported to the user. This situation makes it
difficult for admins to root cause.
Log a message when this condition occurs.

On some architectures, the MMU can be disabled, leading to access_ok()
becoming an empty macro that does not evaluate its size argument,
which in turn produces an unused-variable warning:
drivers/vhost/vhost.c:1191:9: error: unused variable 's' [-Werror,-Wunused-variable]
size_t s = vhost_has_feature(vq, VIRTIO_RING_F_EVENT_IDX) ? 2 : 0;
Mark the variable as __maybe_unused to shut up that warning.

A virtio transport is free to implement some of the callbacks in
virtio_config_ops in a matter that they cannot be called from
atomic context (e.g. virtio-ccw, which maps a lot of the callbacks
to channel I/O, which is an inherently asynchronous mechanism).
This can be very surprising for developers using the much more
common virtio-pci transport, just to find out that things break
when used on s390.
The documentation for virtio_config_ops now contains a comment
explaining this, but it makes sense to add a might_sleep() annotation
to various wrapper functions in the virtio core to avoid surprises
later.
Note that annotations are NOT added to two classes of calls:
- direct calls from device drivers (all current callers should be
fine, however)
- calls which clearly won't be made from atomic context (such as
those ultimately coming in via the driver core)
