It turns that both the C and the H files have the same
kernel-doc markup for the same functions. Let's drop the
at the header file, keeping the one closer to the code.

  This is the cleanup of the latest series of prandom_u32

  The changes to the files were kept minimal, and the controversial
  commit that used to take noise from the fast_pool (f227e3ec) 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"

Commit 21653a41 ("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.

Pull x86 SEV-ES fixes from Borislav Petkov:
 "Three fixes to SEV-ES to correct setting up the new early pagetable on
  5-level paging machines, to always map boot_params and the kernel
  cmdline, and disable stack protector for ../compressed/head{32,64}.c.
  (Arvind Sankar)"

* tag 'x86_seves_fixes_for_v5.10_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/boot/64: Explicitly map boot_params and command line
  x86/head/64: Disable stack protection for head$(BITS).o
  x86/boot/64: Initialize 5-level paging variables earlier

Given that this code is new, let's add a selftest for it as well.
It doesn't rely on fixed sets, instead it picks 1024 numbers and
verifies that they're not more correlated than desired.
