Pull thermal updates from Zhang Rui:

 - Fix a regression where bogus trip points on some Lenovo laptops start
   to screw up thermal control after commit 81ad4276 ("Thermal:
   initialize thermal zone device correctly").

   On these Lenovo laptops, a bogus passive trip point is reported,
   which is 0 degree Celsius.  Without commit 81ad4276, thermal zone
   fails to set cooling devices to proper cooling state, which is a bug.
   But with commit 81ad4276 applied, the processors are always
   throttled on these Lenovo laptops because the current temperature is
   always higher than the passive trip point.

Currently we disable preemption in copy_to_user_page; a behaviour that
we inherited from the 32-bit arm code. This was necessary for older
cores without broadcast data cache maintenance, and ensured that cache
lines were dirtied and cleaned by the same CPU. On these systems dirty
cache line migration was not possible, so this was sufficient to
guarantee coherency.

On contemporary systems, cache coherence protocols permit (dirty) cache
lines to migrate between CPUs as a result of speculation, prefetching,
and other behaviours. To account for this, in ARMv8 data cache
maintenance operations are broadcast and affect all data caches in the
domain associated with the VA (i.e. ISH for kernel and user mappings).

In __switch_to we ensure that tasks can be safely migrated in the middle
of a maintenance sequence, using a dsb(ish) to ensure prior explicit
memory accesses are observed and cache maintenance operations are
completed before a task can be run on another CPU.

Given the above, it is not necessary to disable preemption in
copy_to_user_page. This patch removes the preempt_{disable,enable}
calls, permitting preemption.

Commit 324420bf ("arm64: add support for ioremap() block
mappings") added new p?d_set_huge functions which do the hard work to
generate and set a correct block entry.

These differ from open-coded huge page creation in the early page table
code by explicitly setting the P?D_TYPE_SECT bits (which are implicitly
retained by mk_sect_prot() for any valid prot), but are otherwise
identical (and cannot fail on arm64).

For simplicity and consistency, make use of these in the initial page
table creation code.

The KASLR code incorrectly expects the contents of x18 to be preserved
across a call into C code, and uses it to stash the contents of SCTLR_EL1
before enabling the MMU. If the MMU needs to be disabled again to create
the randomized kernel mapping, x18 is written back to SCTLR_EL1, which is
likely to crash the system if x18 has been clobbered by kasan_early_init()
or kaslr_early_init(). So use x22 instead, which is not in use so far in
head.S

after vmbus_open() is called. This avoid pontential race of removing device
