SPDX update for 5.2-rc2, round 2
Here is another set of reviewed patches that adds SPDX tags to different kernel files, based on a set of rules that are being used to parse the comments to try to determine that the license of the file is "GPL-2.0-or-later". Only the "obvious" versions of these matches are included here, a number of "non-obvious" variants of text have been found but those have been postponed for later review and analysis. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers.

platform/x86: pmc_atom: Add several Beckhoff Automation boards to critclk_systems DMI table
There are several Beckhoff Automation industrial PC boards which use
pmc_plt_clk* clocks for ethernet controllers. This adds affected boards
to critclk_systems DMI table so the clocks are marked as CLK_CRITICAL and
not turned off.

mm/gup: change GUP fast to use flags rather than a write 'bool'
To facilitate additional options to get_user_pages_fast() change the singular write parameter to be gup_flags. This patch does not change any functionality. New functionality will follow in subsequent patches. Some of the get_user_pages_fast() call sites were unchanged because they already passed FOLL_WRITE or 0 for the write parameter. NOTE: It was suggested to change the ordering of the get_user_pages_fast() arguments to ensure that callers were converted.

platform/chrome: Add support for v1 of host sleep event
Add support in code for the new forms of the host sleep event. Detects the presence of this version of the command at runtime, and use whichever form the EC supports. At this time, always request the default timeout, and only report the failing response via a WARN_ONCE(). Future versions could accept the sleep parameter from outside the driver, and return the response information to usermode or elsewhere.

platform/x86: asus-wmi: Add fn-lock mode switch support
Some of latest ASUS laptops support new fn-lock mode switching. This commit detect whether if the fn-lock option is enabled in BIOS setting, and toggle the fn-lock mode via a new WMI DEVID 0x00100023 when the corresponding notify code captured. The ASUS fn-lock mode switch is activated by pressing Fn+Esc. When on, keys F1 to F12 behave as applicable, with meanings defined by the application being used at the time. When off, F1 to F12 directly triggers hardware features, well known audio volume up/down, brightness up/down...etc, which were triggered by holding down Fn key and F-keys. Because there's no way to retrieve the fn-lock mode via existing WMI methods per ASUS spec, driver need to initialize and keep the fn-lock mode by itself.

platform/x86: ideapad-laptop: Remove no_hw_rfkill_list
When the ideapad-laptop driver was first written it was written for laptops which had a hardware rfkill switch. So when the first ideapad laptops showed up without a hw rfkill switch and it turned out that in this case the ideapad firmware interface would always report the wifi being hardware- blocked, a DMI id list of models which lack a hw rfkill switch was started (by yours truly). Things were done this way to avoid regressing existing models with a hw rfkill switch. In hindsight this was a mistake. Lenovo releases a lot of ideapad models every year and even the latest models still use the "VPC2004" ACPI interface the ideapad-laptop driver binds to. Having a hw rfkill switch is quite rare on modern hardware, so all these new models need to be added to the no_hw_rfkill_list, leading to a never ending game of whack a mole. Worse the failure mode when not present on the list, is very bad. In this case the ideapad-laptop driver will report the wifi as being hw-blocked, at which points NetworkManager does not even try to use it and the user ends up with non working wifi. This leads to various Linux fora on the internet being filled with wifi not working on ideapad laptops stories, which does not make Linux look good. The failure mode when we flip the default to assuming that a hw rfkill switch is not present OTOH is quite benign. When we properly report the wifi as being hw-blocked on ideapads which do have the hw-switch; and it is in the wifi-off position, then at least when using NetworkManager + GNOME3 the user will get a "wifi disabled in hardware" message when trying to connect to the wifi from the UI. If OTOH we assume there is no hardware rfkill switch, then the user will get an empty list for the list of available networks. Although the empty list vs the "wifi disabled in hardware" message is a regression, it is a very minor regression and it can easily be fixed on a model by model basis by filling the new hw_rfkill_list this commit introduces. Therefor this commit removes the ever growing no_hw_rfkill_list, flipping the default to assuming there is no hw rfkill switch and adding a new hw_rfkill_list. Thereby fixing the wifi not working on all the current ideapad and yoga models which are not on the list yet and also fixing it for all future ideapad and yoga models using the "VPC2004" ACPI interface. Note once this patch has been accepted upstream. I plan to write a blog post asking for users of ideapads and yoga's with a hw rfkill switch to step forward, so that we can populate the new hw_rfkill_list with the few older yoga and ideapad models which actually have a hw rfkill switch.

platform/x86: intel_pmc_core: Allow to dump debug registers on S0ix failure
Add a module parameter which when enabled, will check on resume, if the last S0ix attempt was successful. If not, the driver would warn and provide helpful debug information (which gets latched during the failed suspend attempt) to debug the S0ix failure. This information is very useful to debug S0ix failures. Specially since the latched debug information will be lost (over-written) if the system attempts to go into runtime (or imminent) S0ix again after that failed suspend attempt.

platform/x86: intel_pmc_ipc: Don't map non-used optional resources
The intel_pmc_ipc driver has a placeholder for all possible resources
that may have been provided by ACPI. Since there are few optional ones,
the driver still uses them and binds to wrong ranges in resource tree:
# grep intel_punit_ipc /proc/iomem
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
This leads to issues with resource management during inserting and
removing modules, such as intel_pmc_ipc itself, which can't be inserted
anymore after first removal.
Count the actual resources provided and supply only them to the child device.
This is a real fix of the commit

platform/x86: alienware-wmi: fix kfree on potentially uninitialized pointer
Currently the kfree of output.pointer can be potentially freeing
an uninitalized pointer in the case where out_data is NULL. Fix this
by reworking the case where out_data is not-null to perform the
ACPI status check and also the kfree of outpoint.pointer in one block
and hence ensuring the pointer is only freed when it has been used.
Also replace the if (ptr != NULL) idiom with just if (ptr).

platform/chrome: wilco_ec: Add h1_gpio status to debugfs
As part of Chrome OS's FAFT (Fully Automated Firmware Testing) tests, we need to ensure that the H1 chip is properly setting some GPIO lines. The h1_gpio attribute exposes the state of the lines: - ENTRY_TO_FACT_MODE in BIT(0) - SPI_CHROME_SEL in BIT(1) There are two reasons that I am exposing this in debugfs, and not as a GPIO: 1. This is only useful for testing, so end users shouldn't ever care about this. In fact, if it passes the tests, then the value of h1_gpio will always be 2, so it would be really uninteresting for users. 2. This GPIO is not connected to, controlled by, or really even related to the AP. The GPIO runs between the EC and the H1 security chip. Changes in v4: - Use "0x02x\n" instead of "02x\n" for format string - Use DEFINE_DEBUGFS_ATTRIBUTE() - Add documentation Changes in v3: - Fix documentation to correspond with formatting change in v2. Changes in v2: - Zero out the unused fields in the request. - Format result as "%02x\n" instead of as a decimal.

platform/chrome: wilco_ec: Standardize mailbox interface
The current API for the wilco EC mailbox interface is bad. It assumes that most messages sent to the EC follow a similar structure, with a command byte in MBOX[0], followed by a junk byte, followed by actual data. This doesn't happen in several cases, such as setting the RTC time, using the raw debugfs interface, and reading or writing properties such as the Peak Shift policy (this last to be submitted soon). Similarly for the response message from the EC, the current interface assumes that the first byte of data is always 0, and the second byte is unused. However, in both setting and getting the RTC time, in the debugfs interface, and for reading and writing properties, this isn't true. The current way to resolve this is to use WILCO_EC_FLAG_RAW* flags to specify when and when not to skip these initial bytes in the sent and received message. They are confusing and used so much that they are normal, and not exceptions. In addition, the first byte of response in the debugfs interface is still always skipped, which is weird, since this raw interface should be giving the entire result. Additionally, sent messages assume the first byte is a command, and so struct wilco_ec_message contains the "command" field. In setting or getting properties however, the first byte is not a command, and so this field has to be filled with a byte that isn't actually a command. This is again inconsistent. wilco_ec_message contains a result field as well, copied from wilco_ec_response->result. The message result field should be removed: if the message fails, the cause is already logged, and the callers are alerted. They will never care about the actual state of the result flag. These flags and different cases make the wilco_ec_transfer() function, used in wilco_ec_mailbox(), really gross, dealing with a bunch of different cases. It's difficult to figure out what it is doing. Finally, making these assumptions about the structure of a message make it so that the messages do not correspond well with the specification for the EC's mailbox interface. For instance, this interface specification may say that MBOX[9] in the received message contains some information, but the calling code needs to remember that the first byte of response is always skipped, and because it didn't set the RESPONSE_RAW flag, the next byte is also skipped, so this information is actually contained within wilco_ec_message->response_data[7]. This makes it difficult to maintain this code in the future. To fix these problems this patch standardizes the mailbox interface by: - Removing the WILCO_EC_FLAG_RAW* flags - Removing the command and reserved_raw bytes from wilco_ec_request - Removing the mbox0 byte from wilco_ec_response - Simplifying wilco_ec_transfer() because of these changes - Gives the callers of wilco_ec_mailbox() the responsibility of exactly and consistently defining the structure of the mailbox request and response - Removing command and result from wilco_ec_message. This results in the reduction of total code, and makes it much more maintainable and understandable.

platform/chrome: cros_ec_proto: check for NULL transfer function
As new transfer mechanisms are added to the EC codebase, they may not support v2 of the EC protocol. If the v3 initial handshake transfer fails, the kernel will try and call cmd_xfer as a fallback. If v2 is not supported, cmd_xfer will be NULL, and the code will end up causing a kernel panic. Add a check for NULL before calling the transfer function, along with a helpful comment explaining how one might end up in this situation.

platform/chrome: cros_ec_spi: Transfer messages at high priority
The software running on the Chrome OS Embedded Controller (cros_ec)
handles SPI transfers in a bit of a wonky way. Specifically if the EC
sees too long of a delay in a SPI transfer it will give up and the
transfer will be counted as failed. Unfortunately the timeout is
fairly short, though the actual number may be different for different
EC codebases.
We can end up tripping the timeout pretty easily if we happen to
preempt the task running the SPI transfer and don't get back to it for
a little while.
Historically this hasn't been a _huge_ deal because:
1. On old devices Chrome OS used to run PREEMPT_VOLUNTARY. That meant
we were pretty unlikely to take a big break from the transfer.
2. On recent devices we had faster / more processors.
3. Recent devices didn't use "cros-ec-spi-pre-delay". Using that
delay makes us more likely to trip this use case.
4. For whatever reasons (I didn't dig) old kernels seem to be less
likely to trip this.
5. For the most part it's kinda OK if a few transfers to the EC fail.
Mostly we're just polling the battery or doing some other task
where we'll try again.
Even with the above things, this issue has reared its ugly head
periodically. We could solve this in a nice way by adding reliable
retries to the EC protocol [1] or by re-designing the code in the EC
codebase to allow it to wait longer, but that code doesn't ever seem
to get changed. ...and even if it did, it wouldn't help old devices.
It's now time to finally take a crack at making this a little better.
This patch isn't guaranteed to make every cros_ec SPI transfer
perfect, but it should improve things by a few orders of magnitude.
Specifically you can try this on a rk3288-veyron Chromebook (which is
slower and also _does_ need "cros-ec-spi-pre-delay"):
md5sum /dev/zero &
md5sum /dev/zero &
md5sum /dev/zero &
md5sum /dev/zero &
while true; do
cat /sys/class/power_supply/sbs-20-000b/charge_now > /dev/null;
done
...before this patch you'll see boatloads of errors. After this patch I
don't see any in the testing I did.
The way this patch works is by effectively boosting the priority of
the cros_ec transfers. As far as I know there is no simple way to
just boost the priority of the current process temporarily so the way
we accomplish this is by queuing the work on the system_highpri_wq.
NOTE: this patch relies on the fact that the SPI framework attempts to
push the messages out on the calling context (which is the one that is
boosted to high priority). As I understand from earlier (long ago)
discussions with Mark Brown this should be a fine assumption. Even if
it isn't true sometimes this patch will still not make things worse.
