commit 685a755089f95b7e205c0202567d9a647f9de096 upstream.

These commands are necessary to avoid severely abnormal and inaccurate
temperature readings that are caused by using the default commands.

[ Upstream commit 1a4aabc27e95674837f2e25f4ef340c0469e6203 ]

According to POSIX spec, EAGAIN returned by read with O_NONBLOCK set
means the read would block. Hence, the common implementation in
nonblocking model will poll the file when the nonblocking read returns
EAGAIN. However, when the target file is thermal zone, this mechanism
will totally malfunction because thermal zone doesn't implement sysfs
notification and thus the poll will never return.

For example, the read in Golang implemnts such method and sometimes
hangs at reading some thermal zones via sysfs.

Change to return -ENODATA instead of -EAGAIN to userspace.

[ Upstream commit f8e157ff2df46ddabd930815d196895976227831 ]

Certain TEMP_ALARM GEN2 PMIC peripherals need over-temperature stage 2
automatic PMIC partial shutdown. This will ensure that in the event of
reaching the hotter stage 3 over-temperature threshold, repeated faults
will be avoided during the automatic PMIC hardware full shutdown.
Modify the stage 2 shutdown control logic to ensure that stage 2
shutdown is enabled on all affected PMICs. Read the digital major
and minor revision registers to identify these PMICs.

Pull core x86 updates from Ingo Molnar:
 "Boot code changes:

   - A large series of changes to reorganize the x86 boot code into a
     better isolated and easier to maintain base of PIC early startup
     code in arch/x86/boot/startup/, by Ard Biesheuvel.

     Motivation & background:

  	| Since commit
  	|
  	|    c88d71508e36 ("x86/boot/64: Rewrite startup_64() in C")
  	|
  	| dated Jun 6 2017, we have been using C code on the boot path in a way
  	| that is not supported by the toolchain, i.e., to execute non-PIC C
  	| code from a mapping of memory that is different from the one provided
  	| to the linker. It should have been obvious at the time that this was a
  	| bad idea, given the need to sprinkle fixup_pointer() calls left and
  	| right to manipulate global variables (including non-pointer variables)
  	| without crashing.
  	|
  	| This C startup code has been expanding, and in particular, the SEV-SNP
  	| startup code has been expanding over the past couple of years, and
  	| grown many of these warts, where the C code needs to use special
  	| annotations or helpers to access global objects.

     This tree includes the first phase of this work-in-progress x86
