2021-06-21RDMA/hns: Remove the unused hns_roce_bitmap_free_range functionYangyang Li
hns_roce_bitmap_free_range() is only called inside hns_roce_bitmap_free(), and the input parameter "cnt" is set to a constant 1. In addition, the driver does not use alloc_range scenarios, so free_range does not need to exist.

2021-06-21Merge series "Extend regulator notification support" from Matti Vaittinen ↵Mark Brown
<matti.vaittinen@fi.rohmeurope.com>: Extend regulator notification support This series extends the regulator notification and error flag support. Initial discussion on the topic can be found here: https://lore.kernel.org/lkml/6046836e22b8252983f08d5621c35ececb97820d.camel@fi.rohmeurope.com/ In a nutshell - the series adds: 1. WARNING level events/error flags. (Patch 3) Current regulator 'ERROR' event notifications for over/under voltage, over current and over temperature are used to indicate condition where monitored entity is so badly "off" that it actually indicates a hardware error which can not be recovered. The most typical hanling for that is believed to be a (graceful) system-shutdown. Here we add set of 'WARNING' level flags to allow sending notifications to consumers before things are 'that badly off' so that consumer drivers can implement recovery-actions. 2. Device-tree properties for specifying limit values. (Patches 1, 5) Add limits for above mentioned 'ERROR' and 'WARNING' levels (which send notifications to consumers) and also for a 'PROTECTION' level (which will be used to immediately shut-down the regulator(s) W/O informing consumer drivers. Typically implemented by hardware). Property parsing is implemented in regulator core which then calls callback operations for limit setting from the IC drivers. A warning is emitted if protection is requested by device tree but the underlying IC does not support configuring requested protection. 3. Helpers which can be registered by IC. (Patch 4) Target is to avoid implementing IRQ handling and IRQ storm protection in each IC driver. (Many of the ICs implementin these IRQs do not allow masking or acking the IRQ but keep the IRQ asserted for the whole duration of problem keeping the processor in IRQ handling loop). 4. Emergency poweroff function (refactored out of the thermal_core to kernel/reboot.c) which is called if IC fires error IRQs but IC reading fails and given retry-count is exceeded. (Patches 2, 4) Please note that the mutex in the emergency shutdown was replaced by a simple atomic in order to allow call from any context. The helper was attempted to be done so it could be used to implement roughly same logic as is used in qcom-labibb regulator. This means amongst other things a safety shut-down if IC registers are not readable. Using these shut-down retry counters are optional. The idea is that the helper could be also used by simpler ICs which do not provide status register(s) which can be used to check if error is still active. ICs which do not have such status register can simply omit the 'renable' callback (and retry-counts etc) - and helper assumes the situation is Ok and re-enables IRQ after given time period. If problem persists the handler is ran again and another notification is sent - but at least the delay allows processor to avoid IRQ loop. Patch 7 takes this notification support in use at BD9576MUF. Patch 8 is related to MFD change which is not really related to the RFC here. It was added to this series in order to avoid potential conflicts. Patch 9 adds a maintainers entry. Changelog v10-RESEND: - rebased on v5.13-rc4 Changelog v10: - rebased on v5.13-rc2 - Move rdev_*() print macros to the internal.h and use rdev_dbg() from irq_helpers.c - Export rdev_get_name() and move it from coupler.h to driver.h for others to use. (It was already in coupler.h but not exported - usage was limited and coupler.h does not sound like optimal place as rdev_name is not only used by coupled regulators) - Send all regulator notifications from irq_helpers.c at one OR'd event for the sake of simplicity. For BD9576 this does not matter as it has own IRQ for each event case. Header defining events says they may be OR'd. - Change WARN() at protection shutdown to pr_emerg as suggested by Petr. Changelog v9: - rebases on v5.13-rc1 - Update thermal documentation - Fix regulator notification event number Changelog v8: - split shutdown API adding and thermal core taking it in use to own patches. - replace the spinlock with atomic when ensuring the emergency shutdown is only called once. Changelog v7: general: - rebased on v5.12-rc7 - new patch for refactoring the hw-failure reboot logic out of thermal_core.c for others to use. notification helpers: - fix regulator error_flags query - grammar/typos - do not BUG() but attempt to shut-down the system - use BITS_PER_TYPE() Changelog v6: Add MAINTAINERS entry Changes to IRQ notifiers - move devm functions to drivers/regulator/devres.c - drop irq validity check - use devm_add_action_or_reset() - fix styling issues - fix kerneldocs Changelog v5: - Fix the badly formatted pr_emerg() call.

2021-06-21ACPI: EC: trust DSDT GPE for certain HP laptopZhang Rui
On HP Pavilion Gaming Laptop 15-cx0xxx, the ECDT EC and DSDT EC share the same port addresses but different GPEs. And the DSDT GPE is the right one to use. The current code duplicates DSDT EC with ECDT EC if the port addresses are the same, and uses ECDT GPE as a result, which breaks this machine. Introduce a new quirk for the HP laptop to trust the DSDT GPE, and avoid duplicating even if the port addresses are the same.

2021-06-21ACPI: scan: Simplify acpi_table_events_fn()Rafael J. Wysocki
Notice that the table field of struct acpi_table_events_work is never read and its event field is always equal to ACPI_TABLE_EVENT_LOAD, so both of them are redundant. Accordingly, drop struct acpi_table_events_work and use struct work_struct directly instead of it, simplify acpi_scan_table_handler() and rename it to acpi_scan_table_notify(). Moreover, make acpi_bus_table_handler() check the event code against ACPI_TABLE_EVENT_LOAD before calling acpi_scan_table_notify(), so it is not necessary to do that check in the latter. No intentional functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

2021-06-21drm: add a locked version of drm_is_current_masterDesmond Cheong Zhi Xi
While checking the master status of the DRM file in drm_is_current_master(), the device's master mutex should be held. Without the mutex, the pointer fpriv->master may be freed concurrently by another process calling drm_setmaster_ioctl(). This could lead to use-after-free errors when the pointer is subsequently dereferenced in drm_lease_owner(). The callers of drm_is_current_master() from drm_auth.c hold the device's master mutex, but external callers do not. Hence, we implement drm_is_current_master_locked() to be used within drm_auth.c, and modify drm_is_current_master() to grab the device's master mutex before checking the master status.

2021-06-21regulator: bd9576: Support error reportingMatti Vaittinen
BD9573 and BD9576 support set of "protection" interrupts for "fatal" issues. Those lead to SOC reset as PMIC shuts the power outputs. Thus there is no relevant IRQ handling for them. Few "detection" interrupts were added to the BD9576 with the idea that SOC could take some recovery-action before error gets unrecoverable. Add support for over and under voltage detection for Vout1 ... Vout4 and VoutL1. Add over-current detection for VoutS1 and finally a thermal warning (common for all regulators) which alerts 30 C before temperature reaches the thermal shutdown point. This way consumer drivers can build error-recovery mechanisms. Unfortunately the BD9576 interrupt logic was not re-evaluated. IRQs are not designed to be properly acknowleged - and IRQ line is kept active for whole duration of error condition (in comparison to informing only about state change).

2021-06-21extcon: sm5502: Add support for SM5504Stephan Gerhold
SM5504 is another MUIC from Silicon Mitus that is fairly similar to SM5502. They seem to use the same register set, but: - SM5504 has some additional bits in SM5502_REG_CONTROL - SM5504 has a quite different set of interrupts - SM5504 reports USB OTG as dev_type1 = BIT(0) instead of BIT(7) Overall it's minor and we can support this by defining a separate struct sm5502_type for SM5504.

2021-06-21s390/vfio-ap: clean up mdev resources when remove callback invokedTony Krowiak
The mdev remove callback for the vfio_ap device driver bails out with -EBUSY if the mdev is in use by a KVM guest (i.e., the KVM pointer in the struct ap_matrix_mdev is not NULL). The intended purpose was to prevent the mdev from being removed while in use. There are two problems with this scenario: 1. Returning a non-zero return code from the remove callback does not prevent the removal of the mdev. 2. The KVM pointer in the struct ap_matrix_mdev will always be NULL because the remove callback will not get invoked until the mdev fd is closed. When the mdev fd is closed, the mdev release callback is invoked and clears the KVM pointer from the struct ap_matrix_mdev. Let's go ahead and remove the check for KVM in the remove callback and allow the cleanup of mdev resources to proceed.
