Input: hideep - optionally reset controller work mode to native HiDeep protocol
The HiDeep IST940E touchscreen controller used on the Lenovo Yoga Book X90F
convertible comes up in HID mode by default.
This works well on the X91F Windows model where the touchscreen is
correctly described in ACPI and ACPI takes care of controlling
the reset GPIO and regulators.
But the X90F ships with Android and the ACPI tables on this model don't
describe the touchscreen. Instead this is hardcoded in the vendor kernel.
The vendor kernel uses the touchscreen in native HiDeep 20 (2.0?) protocol
mode and switches the controller to this mode by writing 0 to reg 0x081e.
Adjusting the i2c-hid code to deal with the reset-gpio and regulators on
this non devicetree (but rather broken ACPI) convertible is somewhat tricky
and the native protocol reports ABS_MT_PRESSURE and ABS_MT_TOUCH_MAJOR
which are not reported in HID mode, so it is preferable to use the native
mode.
Add support to the hideep driver to reset the work-mode to the native
HiDeep protocol to allow using it on the Lenovo Yoga Book X90F.
This is guarded behind a new "hideep,force-native-protocol" boolean
property, to avoid changing behavior on other devices.
For the record: I did test using the i2c-hid driver with some quick hacks
and it does work. The I2C-HID descriptor is available from address 0x0020,
just like on the X91F Windows model.
So far the new "hideep,force-native-protocol" property is only used on
x86/ACPI (non devicetree) devs. IOW it is not used in actual devicetree
files. The devicetree-bindings maintainers have requested properties like
these to not be added to the devicetree-bindings, so the new property is
deliberately not added to the existing devicetree-bindings.

Mario Limonciello [Tue, 28 Feb 2023 02:44:39 +0000 (20:44 -0600)]
tpm: disable hwrng for fTPM on some AMD designs
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/eventlog: Don't abort tpm_read_log on faulty ACPI address
tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI

cpumask: relax sanity checking constraints
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.

ext4_try_add_inline_entry
__ext4_mark_inode_dirty

entry = (struct ext4_xattr_entry *)((void *)raw_inode +
EXT4_I(inode)->i_inline_off);
free += EXT4_XATTR_SIZE(le32_to_cpu(entry->e_value_size));
->As entry is incorrect, then 'free' may be negative
ext4_update_inline_data
value = kzalloc(len, GFP_NOFS);
-> len is unsigned int, maybe very large, then trigger warning when
'kzalloc()'
To resolve the above issue we need to update 'i_inline_off' after
'ext4_xattr_shift_entries()'. We do not need to set
EXT4_STATE_MAY_INLINE_DATA flag here, since ext4_mark_inode_dirty()
already sets this flag if needed. Setting EXT4_STATE_MAY_INLINE_DATA
when it is needed may trigger a BUG_ON in ext4_writepages().

ext4: move where set the MAY_INLINE_DATA flag is set
The only caller of ext4_find_inline_data_nolock() that needs setting of
EXT4_STATE_MAY_INLINE_DATA flag is ext4_iget_extra_inode(). In
ext4_write_inline_data_end() we just need to update inode->i_inline_off.
Since we are going to add one more caller that does not need to set
EXT4_STATE_MAY_INLINE_DATA, just move setting of EXT4_STATE_MAY_INLINE_DATA

RISC-V: Don't check text_mutex during stop_machine
We're currently using stop_machine() to update ftrace & kprobes, which
means that the thread that takes text_mutex during may not be the same
as the thread that eventually patches the code. This isn't actually a
race because the lock is still held (preventing any other concurrent
accesses) and there is only one thread running during stop_machine(),
but it does trigger a lockdep failure.
This patch just elides the lockdep check during stop_machine.

i2c: dev: Fix bus callback return values
The i2cdev_{at,de}tach_adapter() callbacks are used for two purposes:
1. As notifier callbacks, when (un)registering I2C adapters created or
destroyed after i2c_dev_init(),
2. As bus iterator callbacks, for registering already existing
adapters from i2c_dev_init(), and for cleanup.
Unfortunately both use cases expect different return values: the former
expects NOTIFY_* return codes, while the latter expects zero or error
codes, and aborts in case of error.
Hence in case 2, as soon as i2cdev_{at,de}tach_adapter() returns
(non-zero) NOTIFY_OK, the bus iterator aborts. This causes (a) only the
first already existing adapter to be registered, leading to missing
/dev/i2c-* entries, and (b) a failure to unregister all but the first
I2C adapter during cleanup.
Fix this by introducing separate callbacks for the bus iterator,
wrapping the notifier functions, and always returning succes.
Any errors inside these callback functions are unlikely to happen, and
are fatal anyway.

b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back

not take an i2c_device_id parameter. Now that all in-tree drivers are
converted to the temporary .probe_new() callback, .probe() can be
modified to match the desired prototype.
Now that .probe() and .probe_new() have the same semantic, they can be
defined as members of an anonymous union to save some memory and
simplify the core code a bit.

We fetch %SR value from sigframe; it might have been modified by signal
handler, so we can't trust it with any bits that are not modifiable in

io_uring: silence variable ‘prev’ set but not used warning
If io_uring.o is built with W=1, it triggers a warning:
io_uring/io_uring.c: In function ‘__io_submit_flush_completions’:
io_uring/io_uring.c:1502:40: warning: variable ‘prev’ set but not used [-Wunused-but-set-variable]
1502 | struct io_wq_work_node *node, *prev;
| ^~~~
which is due to the wq_list_for_each() iterator always keeping a 'prev'
variable. Most users need this to remove an entry from a list, for
example, but __io_submit_flush_completions() never does that.
Add a basic helper that doesn't track prev instead, and use that in
that function.

io_uring/uring_cmd: ensure that device supports IOPOLL
It's possible for a file type to support uring commands, but not
pollable ones. Hence before issuing one of those, we should check
that it is supported and error out upfront if it isn't.
