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.

2020-10-25i2c: core: Restore acpi_walk_dep_device_list() getting called after ↵Hans de Goede1-1/+10
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.
