This was a leftover from the legacy alloc_disk interface. Switch
the scsi ULPs and dasd to set ->minors directly like all other
drivers and remove the argument.

Most drivers should use and have been converted to use blk_alloc_disk
and blk_mq_alloc_disk. Only the scsi ULPs and dasd still allocate
a disk separately from the request_queue, so don't bother with
convenience macros for something that should not see significant
new users and remove these wrappers.

Pass the lockdep name to the low-level __blk_alloc_disk helper and
hardcode the name for it given that the number of minors or node_id
are not very useful information. While this passes a pointless
argument for non-lockdep builds that is not really an issue as
disk allocation is a probe time only slow path.

Retrieve and print retry_rd_err_log registers like the earlier change:
commit e80634a75aba ("EDAC, skx: Retrieve and print retry_rd_err_log registers")
This is a little trickier than on Skylake because of potential
interference with BIOS use of the same registers. The default
behavior is to ignore these registers.
A module parameter retry_rd_err_log(default=0) controls the mode of operation:
- 0=off : Default.
- 1=bios : Linux doesn't reset any control bits, but just reports values.
This is "no harm" mode, but it may miss reporting some data.
- 2=linux: Linux tries to take control and resets mode bits,
clears valid/UC bits after reading. This should be
more reliable (especially if BIOS interference is reduced
by disabling eMCA reporting mode in BIOS setup).

MCDDRCFG is a per-channel register and uses bit{0,1} to indicate
the NVDIMM presence on DIMM slot{0,1}. Current i10nm_edac driver
wrongly uses MCDDRCFG as per-DIMM register and fails to detect
the NVDIMM.
Fix it by reading MCDDRCFG as per-channel register and using its
bit{0,1} to check whether the NVDIMM is populated on DIMM slot{0,1}.

Hit kernel warning like this, it can be reproduced by verifying 256
bytes datafile by keyctl command, run script:
RAWDATA=rawdata
SIGDATA=sigdata
modprobe pkcs8_key_parser
rm -rf *.der *.pem *.pfx
rm -rf $RAWDATA
dd if=/dev/random of=$RAWDATA bs=256 count=1
openssl req -nodes -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem \
-subj "/C=CN/ST=GD/L=SZ/O=vihoo/OU=dev/CN=xx.com/emailAddress=yy@xx.com"
KEY_ID=`openssl pkcs8 -in key.pem -topk8 -nocrypt -outform DER | keyctl \
padd asymmetric 123 @s`
keyctl pkey_sign $KEY_ID 0 $RAWDATA enc=pkcs1 hash=sha1 > $SIGDATA
keyctl pkey_verify $KEY_ID 0 $RAWDATA $SIGDATA enc=pkcs1 hash=sha1
Then the kernel reports:
WARNING: CPU: 5 PID: 344556 at crypto/rsa-pkcs1pad.c:540
pkcs1pad_verify+0x160/0x190
...
Call Trace:

keyctl_pkey_verify+0xa5/0x100
do_syscall_64+0x35/0xb0
entry_SYSCALL_64_after_hwframe+0x44/0xae
The reason of this issue, in function 'asymmetric_key_verify_signature':
'.digest_size(u8) = params->in_len(u32)' leads overflow of an u8 value,
so use u32 instead of u8 for digest_size field. And reorder struct
public_key_signature, it saves 8 bytes on a 64-bit machine.

When rngd is run as root then lots of these types of message will appear
in the kernel log if the TPM has been configured to provide random bytes:
[ 7406.275163] tpm tpm0: tpm_transmit: tpm_recv: error -4
The issue is caused by the following call that is interrupted while
waiting for the TPM's response.
sig = wait_event_interruptible(ibmvtpm->wq, !ibmvtpm->tpm_processing_cmd);
Rather than waiting for the response in the low level driver, have it use
the polling loop in tpm_try_transmit() that uses a command's duration to
poll until a result has been returned by the TPM, thus ending when the
timeout has occurred but not responding to signals and ctrl-c anymore. To
stay in this polling loop extend tpm_ibmvtpm_status() to return
'true' for as long as the vTPM is indicated as being busy in
tpm_processing_cmd. Since the loop requires the TPM's timeouts, get them
now using tpm_get_timeouts() after setting the TPM2 version flag on the
chip.
To recreat the resolved issue start rngd like this:
sudo rngd -r /dev/hwrng -t
sudo rngd -r /dev/tpm0 -t

Add support for using elliptic curve keys for signing modules. It uses
a NIST P384 (secp384r1) key if the user chooses an elliptic curve key
and will have ECDSA support built into the kernel.
Note: A developer choosing an ECDSA key for signing modules should still
delete the signing key (rm certs/signing_key.*) when building an older
version of a kernel that only supports RSA keys. Unless kbuild automati-
cally detects and generates a new kernel module key, ECDSA-signed kernel
modules will fail signature verification.

Way back when this driver was written the I2C framework
used to insist an ID table be defined even if the driver
did not use it in favor of ACPI/OF matching, so it was
added just to placate the hard I2C framework requirement.
This is no longer the case so we can drop the table and
also convert the driver to the new probe interface.

This reverts commit 819fbd3d8ef36c09576c2a0ffea503f5c46e9177.
It turns out that some user-space applications use these uapi header
files, so even though the only user of the interface is an old driver
that was moved to staging, moving the header files causes unnecessary
pain.
Generally, we really don't want user space to use kernel headers
directly (exactly because it causes pain when we re-organize), and
instead copy them as needed. But these things happen, and the headers
were in the uapi directory, so I guess it's not entirely unreasonable.

A module can have two kinds of set params, as per topology requirements.
For example, one pre-init and one post-init. But currently, there is
support for just one type, as the format_config.
This patch extends the format_configs to 4, so as to be able to support
pre-init, post-init and post-bind type of set params, for the same
module, simultaneously.

States SKL_MODULE_LOADED and SKL_MODULE_UNLOADED are redundant with
'loadable' flag in struct skl_module. Additionally
skl_tplg_mixer_dapm_post_pmd_event() sets m_state always to
SKL_MODULE_UNINIT so next unload function isn't called for such modules.

Module configuration may differ between its instances depending on
resources required and input and output audio format. Available
parameters to select from are stored in module resource and interface
(format) lists. These come from topology, together with description of
each of pipe's modules.
Ignoring index value provided by topology and relying always on 0th
entry leads to unexpected module behavior due to under/overbudged
resources assigned or impropper format selection. Fix by taking entry at
index specified by topology.

Commit 94531cfcbe79 ("af_unix: Add unix_stream_proto for sockmap")
introduced a bug for af_unix SEQPACKET type. In unix_shutdown, the
unhash function will call prot->unhash(), which is NULL for SEQPACKET.
And kernel will panic. On ARM32, it will show following messages: (it
likely affects x86 too).
Fix the bug by checking the prot->unhash is NULL or not first.

Intel stress tests reported issues with the clock stop mode,
specifically when trying to do a system suspend while the link is
already pm_runtime suspended.
In this case, we need to disable the shim wake, but when the PCI
parent device is also pm_runtime suspended the SHIM registers are not
accessible.
Since this is an invalid corner case, this patch suggests a pm_runtime
resume of the entire bus to full power (parent+child devices) before
the system suspend so that the shim wake can be disabled.
Unlike the suspend operation, the .prepare callbacks are propagated
from root device to leaf devices. By adding a .prepare callback at the
SoundWire link level, we can double-check the pm_runtime status of the
device as well as its parent PCI device. When the problematic
configuration is detected, the device is pm_runtime resumed - which by
construction also resume its parent.
An additional loop is added to resume all child devices. In theory we
only need to restart the link, but doing so will also cause the
physical devices to synchronize and re-initialize, while their Linux
devices remain pm_runtime suspended. It's simpler to make sure the
codec devices are fully resumed so that we don't have to deal with
zombie states.
This additional loop could have been avoided by adding a .prepare
callback in SoundWire codec drivers. Functionally this would have been
equivalent. The rationale for implementing a loop at the link level is
only to reduce the amount of code required to deal at the codec level
with an Intel corner case - in other words keep codec drivers
independent from Intel platform-specific programming sequences.

The SoundWire Linux devices are created purely based on information
provided by platform firmware (e.g. ACPI DSDT table). When the kernel
finds a matching driver for the device address (_ADR), the probe will
initialize required data structures and initialize pm ops.
When the SoundWire link is started at a later point, the physical
devices will synchronize on the SoundWire frames and report their
attachment status, thereby triggering the enumeration and
initialization of device registers.
This two-step solution was a conscious design decision to allow e.g. a
driver to use sideband mechanisms to turn power rails on. This can
also allow OEMs to describe multiple platforms with the same DSDT
table, the devices that are not physically present in hardware.
The drawback of this approach is a bit of confusion, with more devices
than are actually present in hardware. This results in 'ghost'
devices, for which the driver successfully probes, but that will not
generate any traffic on the bus. suspend-resume transitions are
handled by drivers, and skipped when the devices are not physically
present.
This patch provides a work-around for a second-level of confusion in
platform firmware: some platforms only use HDaudio links, but
nevertheless expose SoundWire 'ghost' devices. This results in error
messages in the Intel driver while trying to suspend/resume these
links. The simplest solution is to add a boolean status flag to skip
all suspend/resume/wake sequences if the link was never started.

The power down sequence sets the link_up flag as false outside of the
mutex_lock. This is potentially unsafe.
In additional the flow in that sequence can be improved by first
testing if the link was powered, setting the link_up flag as false and
proceeding with the power down. In case the CPA bits cannot be
cleared, we only flag an error since we cannot deal with interrupts
any longer.

This happens when close_ctree is called while a dev_replace hasn't
completed. In close_ctree, we suspend the dev_replace, but keep the
replace target around so that we can resume the dev_replace procedure
when we mount the root again. This is the call trace:
close_ctree():
btrfs_dev_replace_suspend_for_unmount();
btrfs_close_devices():
btrfs_close_fs_devices():
btrfs_close_one_device():
ASSERT(!test_bit(BTRFS_DEV_STATE_REPLACE_TGT,
&device->dev_state));
However, since the replace target sticks around, there is a device
with BTRFS_DEV_STATE_REPLACE_TGT set on close, and we fail the
assertion in btrfs_close_one_device.
To fix this, if we come across the replace target device when
closing, we should properly reset it back to allocation state. This
fix also ensures that if a non-target device has a corrupted state and
has the BTRFS_DEV_STATE_REPLACE_TGT bit set, the assertion will still
catch the error.
