2021-05-19mlxsw: spectrum_router: Replace if statement with a switch statementIdo Schimmel
The code was written when only two multipath hash policies were present, so the if statement was sufficient. The next patch and future patches are going to add support for more policies, so move to a switch statement.

2021-05-19net: Add notifications when multipath hash field changeIdo Schimmel
In-kernel notifications are already sent when the multipath hash policy itself changes, but not when the multipath hash fields change. Add these notifications, so that interested listeners (e.g., switch ASIC drivers) could perform the necessary configuration.

2021-05-19nfc: s3fwrn5: i2c: Enable optional clock from device treeStephan Gerhold
S3FWRN5 depends on a clock input ("XI" pin) to function properly. Depending on the hardware configuration this could be an always-on oscillator or some external clock that must be explicitly enabled. So far we assumed that the clock is always-on. Make the driver request an (optional) clock from the device tree and make sure the clock is running before starting S3FWRN5. Note: S3FWRN5 asserts "GPIO2" whenever it needs the clock input to function correctly. On some hardware configurations, GPIO2 is connected directly to an input pin of the external clock provider (e.g. the main PMIC of the SoC). In that case, it can automatically AND the clock enable bit and clock request from S3FWRN5 so that the clock is actually only enabled when needed. It is also conceivable that on some other hardware configuration S3FWRN5's GPIO2 might be connected as a regular GPIO input of the SoC. In that case, follow-up patches could extend the driver to request the GPIO, set up an interrupt and only enable the clock when requested by S3FWRN5.

2021-05-19x86/sev-es: Use __put_user()/__get_user() for data accessesJoerg Roedel
The put_user() and get_user() functions do checks on the address which is passed to them. They check whether the address is actually a user-space address and whether its fine to access it. They also call might_fault() to indicate that they could fault and possibly sleep. All of these checks are neither wanted nor needed in the #VC exception handler, which can be invoked from almost any context and also for MMIO instructions from kernel space on kernel memory. All the #VC handler wants to know is whether a fault happened when the access was tried. This is provided by __put_user()/__get_user(), which just do the access no matter what. Also add comments explaining why __get_user() and __put_user() are the best choice here and why it is safe to use them in this context. Also explain why copy_to/from_user can't be used. In addition, also revert commit 7024f60d6552 ("x86/sev-es: Handle string port IO to kernel memory properly") because using __get_user()/__put_user() fixes the same problem while the above commit introduced several problems: 1) It uses access_ok() which is only allowed in task context. 2) It uses memcpy() which has no fault handling at all and is thus unsafe to use here.

This reverts commit b12d691ea5e01db42ccf3b4207e57cb3ce7cfe91. It turns out this is not ready for primetime yet. The intentions are good, but using remap_pfn_range() requires that there is nothing already mapped in the area, and the i915 code seems to very much intentionally remap the same area multiple times. That will then just trigger the BUG_ON(!pte_none(*pte)); in mm/memory.c: remap_pte_range(). There are also reports of mapping type inconsistencies, resulting in warnings and in screen corruption.

2021-05-19ALSA: line6: Fix racy initialization of LINE6 MIDITakashi Iwai
The initialization of MIDI devices that are found on some LINE6 drivers are currently done in a racy way; namely, the MIDI buffer instance is allocated and initialized in each private_init callback while the communication with the interface is already started via line6_init_cap_control() call before that point. This may lead to Oops in line6_data_received() when a spurious event is received, as reported by syzkaller. This patch moves the MIDI initialization to line6_init_cap_control() as well instead of the too-lately-called private_init for avoiding the race. Also this reduces slightly more lines, so it's a win-win change.

2021-05-19platform/x86: dell-smbios-wmi: Fix oops on rmmod dell_smbiosHans de Goede
init_dell_smbios_wmi() only registers the dell_smbios_wmi_driver on systems where the Dell WMI interface is supported. While exit_dell_smbios_wmi() unregisters it unconditionally, this leads to the following oops: [ 175.722921] ------------[ cut here ]------------ [ 175.722925] Unexpected driver unregister!
