The platforms based on SDM845 SoC locks the access to EDAC registers in the
bootloader. So probing the EDAC driver will result in a crash. Hence,
disable the creation of EDAC platform device on all SDM845 devices.
The issue has been observed on Lenovo Yoga C630 and DB845c.
While at it, also sort the members of `struct qcom_llcc_config` to avoid
any holes in-between.

Not all Qcom platforms support IRQ mode for ECC handling. For those
platforms, the current EDAC driver will not be probed due to missing ECC
IRQ in devicetree.
So add support for polling mode so that the EDAC driver can be used on all
Qcom platforms supporting LLCC.
The polling delay of 5000ms is chosen based on Qcom downstream/vendor
driver.

The Qualcomm LLCC/EDAC drivers were using a fixed register stride for
accessing the (Control and Status Registers) CSRs of each LLCC bank.
This stride only works for some SoCs like SDM845 for which driver
support was initially added.
But the later SoCs use different register stride that vary between the
banks with holes in-between. So it is not possible to use a single register
stride for accessing the CSRs of each bank. By doing so could result in a
crash.
For fixing this issue, let's obtain the base address of each LLCC bank from
devicetree and get rid of the fixed stride. This also means, there is no
need to rely on reg-names property and the base addresses can be obtained
using the index.
First index is LLCC bank 0 and last index is LLCC broadcast. If the SoC
supports more than one bank, then those need to be defined in devicetree
for index from 1..N-1.

Register regions of the LLCC banks are located at different addresses.
Currently, the binding just lists the LLCC0 base address and tries to
cover all the banks using a single size. This is entirely wrong as there
are other register regions that happen to lie inside the size covered by
the binding such as the memory controller and holes.
So this needs to be fixed by specifying the base address of individual
LLCC banks. This approach will break the existing users of this binding
as the register regions are split and the drivers now cannot use
LLCC0 register region for accessing rest of the banks (which is wrong
anyway).
But considering the fact that the binding was wrong from the day one and
also the device drivers going wrong by the binding, this breakage is
acceptable.

tpm: disable hwrng for fTPM on some AMD designs
tpm/eventlog: Don't abort tpm_read_log on faulty ACPI address
|
|
AMD has issued an advisory indicating that having fTPM enabled in
BIOS can cause "stuttering" in the OS. This issue has been fixed
in newer versions of the fTPM firmware, but it's up to system
designers to decide whether to distribute it.
This issue has existed for a while, but is more prevalent starting
with kernel 6.1 because commit b006c439d58db ("hwrng: core - start
hwrng kthread also for untrusted sources") started to use the fTPM
for hwrng by default. However, all uses of /dev/hwrng result in
unacceptable stuttering.
So, simply disable registration of the defective hwrng when detecting
these faulty fTPM versions. As this is caused by faulty firmware, it
is plausible that such a problem could also be reproduced by other TPM
interactions, but this hasn't been shown by any user's testing or reports.
It is hypothesized to be triggered more frequently by the use of the RNG
because userspace software will fetch random numbers regularly.
Intentionally continue to register other TPM functionality so that users
that rely upon PCR measurements or any storage of data will still have
access to it. If it's found later that another TPM functionality is
exacerbating this problem a module parameter it can be turned off entirely
and a module parameter can be introduced to allow users who rely upon
fTPM functionality to turn it on even though this problem is present.

tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI
table is found. If the firmware vendor includes an invalid log address
we are unable to map from the ACPI memory and tpm_read_log() returns -EIO
which would abort discovery of the eventlog.
Change the return value from -EIO to -ENODEV when acpi_os_map_iomem()
fails to map the event log.
The following hardware was used to test this issue:
Framework Laptop (Pre-production)
BIOS: INSYDE Corp, Revision: 3.2

Pull staging driver fixes and removal from Greg KH:
"Here are four small staging driver fixes, and one big staging driver
deletion for 6.3-rc2.
The fixes are:
- rtl8192e driver fixes for where the driver was attempting to
execute various programs directly from the disk for unknown reasons
- rtl8723bs driver fixes for issues found by Hans in testing
The deleted driver is the removal of the r8188eu wireless driver as
now in 6.3-rc1 we have a "real" wifi driver for one that includes
support for many many more devices than this old driver did. So it's
time to remove it as it is no longer needed. The maintainers of this
driver all have acked its removal. Many thanks to them over the years
for working to clean it up and keep it working while the real driver
was being developed.
All of these have been in linux-next this week with no reported
problems"

Pull clone3 fix from Christian Brauner:
"A simple fix for the clone3() system call.
The CLONE_NEWTIME allows the creation of time namespaces. The flag
reuses a bit from the CSIGNAL bits that are used in the legacy clone()
system call to set the signal that gets sent to the parent after the
child exits.
The clone3() system call doesn't rely on CSIGNAL anymore as it uses a
dedicated .exit_signal field in struct clone_args. So we blocked all
CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced
and reused a CSIGNAL bit we forgot to adapt clone3_args_valid()
causing CLONE_NEWTIME with clone3() to be rejected. Fix this"

The cpumask_check() was unnecessarily tight, and causes problems for the
users of cpumask_next().
We have a number of users that take the previous return value of one of
the bit scanning functions and subtract one to keep it in "range". But
since the scanning functions end up returning up to 'small_cpumask_bits'
instead of the tighter 'nr_cpumask_bits', the range really needs to be
using that widened form.
[ This "previous-1" behavior is also the reason we have all those
comments about /* -1 is a legal arg here. */ and separate checks for
that being ok. So we could have just made "small_cpumask_bits-1"
be a similar special "don't check this" value.
Tetsuo Handa even suggested a patch that only does that for
cpumask_next(), since that seems to be the only actual case that
triggers, but that all makes it even _more_ magical and special. So
just relax the check ]
One example of this kind of pattern being the 'c_start()' function in
arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on
other architectures.
