This adds percent-based fan control. Attributes (I hope) follow the
sysfs-interface specification:
* pwm1 - fan speed query/manage
* pwm1_max, pwm1_min - min/max values for fan pwm (constant)
* pwm1_enable - fan control query/manage (enable/disable)
(There is no rpm-based control for now)

Since b2052564e6 ("mm: memcontrol: continue cache reclaim from
offlined groups"), re-mounting the memory controller after using it is
very likely to hang.
The cgroup core assumes that any remaining references after deleting a
cgroup are temporary in nature, and synchroneously waits for them, but
the above-mentioned commit has left-over page cache pin its css until
it is reclaimed naturally. That being said, swap entries and charged
kernel memory have been doing the same indefinite pinning forever, the
bug is just more likely to trigger with left-over page cache.
Reparenting kernel memory is highly impractical, which leaves changing
the cgroup assumptions to reflect this: once a controller has been
mounted and used, it has internal state that is independent from mount
and cgroup lifetime. It can be unmounted and remounted, but it can't
be reconfigured during subsequent mounts.
Don't offline the controller root as long as there are any children,
dead or alive. A remount will no longer wait for these old references
to drain, it will simply mount the persistent controller state again.

As Christoph put it:
Can we just get rid of the warnings? It's fairly annoying as devices
without partitions are perfectly fine and very useful.
Me too I see this message every VM boot for ages on all my
devices. Would love to just remove it. For me a partition-table
is only needed for a booting BIOS, grub, and stuff.

Now that the create_mapping() code in mm/mmu.c is able to support
setting up kernel page tables at initcall time, we can move the whole
virtmap creation to arm64_enable_runtime_services() instead of having
a distinct stage during early boot. This also allows us to drop the
arm64-specific EFI_VIRTMAP flag.

Add page protections for arm64 similar to those in arm.
This is for security reasons to prevent certain classes
of exploits. The current method:
- Map all memory as either RWX or RW. We round to the nearest
section to avoid creating page tables before everything is mapped
- Once everything is mapped, if either end of the RWX section should
not be X, we split the PMD and remap as necessary
- When initmem is to be freed, we change the permissions back to
RW (using stop machine if necessary to flush the TLB)
- If CONFIG_DEBUG_RODATA is set, the read only sections are set
read only.

The pclk supplying the watchdog is controlled via the SGRF register area.
Currently we don't have any clock-type handling external clock bits like
this one. Additionally the SGRF isn't even writable in every boot mode.
But still the clock control is available and in the future someone might
want to use it. Therefore define a simple clock for the time being so
that the watchdog driver can read its rate.

smpboot is very creative with the ways to disable ioapic.
smpboot_clear_io_apic() smpboot_clear_io_apic_irqs() and
disable_ioapic_support() serve a similar purpose.
smpboot_clear_io_apic_irqs() is the most useless of all
functions as it clears a variable which has not been setup yet.
Aside of that it has the same ifdef mess and conditionals around the
ioapic related code, which can now be removed.
