2021-04-13usb: dwc2: Update exit clock gating when port is resumedArtur Petrosyan
Updates the implementation of exiting clock gating mode when core receives port resume. Instead of setting the required bit fields of the registers inline, called the "dwc2_host_exit_clock_gating()" function.

2021-04-13arm64: kprobes: Restore local irqflag if kprobes is cancelledJisheng Zhang
If instruction being single stepped caused a page fault, the kprobes is cancelled to let the page fault handler continue as a normal page fault. But the local irqflags are disabled so cpu will restore pstate with DAIF masked. After pagefault is serviced, the kprobes is triggerred again, we overwrite the saved_irqflag by calling kprobes_save_local_irqflag(). NOTE, DAIF is masked in this new saved irqflag. After kprobes is serviced, the cpu pstate is retored with DAIF masked. This patch is inspired by one patch for riscv from Liao Chang.

2021-04-13platform/x86: intel_pmc_core: export platform global reset bits via etr3 ↵Tamar Mashiah
sysfs file During PCH (platform/board) manufacturing process a global platform reset has to be induced in order for the configuration changes take the effect upon following platform reset. This is an internal platform state and is not intended to be used in the regular platform resets. The setting is exposed via ETR3 (Extended Test Mode Register 3). After the manufacturing process is completed the register cannot be written anymore and is hardware locked. This setting was commonly done by accessing PMC registers via /dev/mem but due to security concerns /dev/mem access is much more restricted, hence the reason for exposing this setting via the dedicated sysfs interface. To prevent post manufacturing abuse the register is protected by hardware locking and the file is set to read-only mode via is_visible handler. The register in MMIO space is defined for Cannon Lake and newer PCHs.

2021-04-13platform/x86: thinkpad_acpi: Correct thermal sensor allocationMark Pearson
On recent Thinkpad platforms it was reported that temp sensor 11 was always incorrectly displaying 66C. It turns out the reason for this is that this location in EC RAM is not a temperature sensor but is the power supply ID (offset 0xC2). Based on feedback from the Lenovo firmware team the EC RAM version can be determined and for the current version (3) only the 0x78 to 0x7F range is used for temp sensors. I don't have any details for earlier versions so I have left the implementation unaltered there. Note - in this block only 0x78 and 0x79 are officially designated (CPU & GPU sensors). The use of the other locations in the block will vary from platform to platform; but the existing logic to detect a sensor presence holds.

2021-04-12net: phy: marvell: fix detection of PHY on Topaz switchesPali Rohár
Since commit fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading"), Linux reports the temperature of Topaz hwmon as constant -75°C. This is because switches from the Topaz family (88E6141 / 88E6341) have the address of the temperature sensor register different from Peridot. This address is instead compatible with 88E1510 PHYs, as was used for Topaz before the above mentioned commit. Create a new mapping table between switch family and PHY ID for families which don't have a model number. And define PHY IDs for Topaz and Peridot families. Create a new PHY ID and a new PHY driver for Topaz's internal PHY. The only difference from Peridot's PHY driver is the HWMON probing method. Prior this change Topaz's internal PHY is detected by kernel as: PHY [...] driver [Marvell 88E6390] (irq=63) And afterwards as: PHY [...] driver [Marvell 88E6341 Family] (irq=63) Signed-off-by: Pali Rohár <pali@kernel.org> BugLink: https://github.com/globalscaletechnologies/linux/issues/1 Fixes: fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading") Reviewed-by: Marek Behún <kabel@kernel.org> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2021-04-12spi: hisi-sfc-v3xx: drop unnecessary ACPI_PTR and related ifendif protectionYicong Yang
We use ACPI_PTR() and related ifendif protection for the id table. This is unnecessary as the struct acpi_device_id is defined in mod_devicetable.h and doesn't rely on ACPI. The driver doesn't use any ACPI apis, so it can be compiled in the ACPI=n case with no warnings. So remove the ACPI_PTR and related ifendif protection, also replace the header acpi.h with mod_devicetable.h.

2021-04-12io_uring: return back safer resurrectPavel Begunkov
Revert of revert of "io_uring: wait potential ->release() on resurrect", which adds a helper for resurrect not racing completion reinit, as was removed because of a strange bug with no clear root or link to the patch. Was improved, instead of rcu_synchronize(), just wait_for_completion() because we're at 0 refs and it will happen very shortly. Specifically use non-interruptible version to ignore all pending signals that may have ended prior interruptible wait. This reverts commit cb5e1b81304e089ee3ca948db4d29f71902eb575.
