This reverts commit 579ced8fdb00b8e94304a83e3cc419f6f8eab08e. Turns out I was overly optimistic about cpu_pm blocking idle being a solution for handling edge interrupts. While it helps in preventing entering idle states that potentially lose context, we can still get an edge interrupt triggering while entering idle. So we need to also add back the workaround for seeing if there are any pending edge interrupts when waking up.

2020-10-26pinctrl: intel: Set default bias in case no particular value givenAndy Shevchenko
When GPIO library asks pin control to set the bias, it doesn't pass any value of it and argument is considered boolean (and this is true for ACPI GpioIo() / GpioInt() resources, by the way). Thus, individual drivers must behave well, when they got the resistance value of 1 Ohm, i.e. transforming it to sane default. In case of Intel pin control hardware the 5 kOhm sounds plausible because on one hand it's a minimum of resistors present in all hardware generations and at the same time it's high enough to minimize leakage current (will be only 200 uA with the above choice).

Hence, additional values can be: 011 ~833.3 Ohm 101 ~952.4 Ohm 110 ~4 kOhm 111 ~800 Ohm That said, convert TERM definitions to be the bit masks to reflect the above.

Pull SafeSetID updates from Micah Morton: "The changes are mostly contained to within the SafeSetID LSM, with the exception of a few 1-line changes to change some ns_capable() calls to ns_capable_setid() -- causing a flag (CAP_OPT_INSETID) to be set that is examined by SafeSetID code and nothing else in the kernel. The changes to SafeSetID internally allow for setting up GID transition security policies, as already existed for UIDs" * tag 'safesetid-5.10' of git://github.com/micah-morton/linux: LSM: SafeSetID: Fix warnings reported by test bot LSM: SafeSetID: Add GID security policy handling LSM: Signal to SafeSetID when setting group IDs

git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom Pull random32 updates from Willy Tarreau: "Make prandom_u32() less predictable. This is the cleanup of the latest series of prandom_u32 experimentations consisting in using SipHash instead of Tausworthe to produce the randoms used by the network stack. The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec3b5c) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless. The resulting code was verified to be very slightly faster on x86_64 than what is was with the controversial commit above, though this remains barely above measurement noise. It was also tested on i386 and arm, and build- tested only on arm64" Link: https://lore.kernel.org/netdev/20200808152628.GA27941@SDF.ORG/ * tag '20201024-v4-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom: random32: add a selftest for the prandom32 code random32: add noise from network and scheduling activity random32: make prandom_u32() output unpredictable
2020-10-25i2c: core: Restore acpi_walk_dep_device_list() getting called after ↵Hans de Goede
registering the ACPI i2c devs Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()")'s intention was to only move the acpi_install_address_space_handler() call to the point before where the ACPI declared i2c-children of the adapter where instantiated by i2c_acpi_register_devices(). But i2c_acpi_install_space_handler() had a call to acpi_walk_dep_device_list() hidden (that is I missed it) at the end of it, so as an unwanted side-effect now acpi_walk_dep_device_list() was also being called before i2c_acpi_register_devices(). Move the acpi_walk_dep_device_list() call to the end of i2c_acpi_register_devices(), so that it is once again called *after* the i2c_client-s hanging of the adapter have been created. This fixes the Microsoft Surface Go 2 hanging at boot.
