Per datasheet, the chip ID for LTM4676 is 0x448x. This was observed
in real systems. In addition to that, chip ID 0x4401 was observed
as well. Research shows that the chip ID has been changed from 0x440x
to 0x448x in datasheet revision C. Add support for the additional chip ID.

Also add the chip ID for LTM4676A, which is functionally identical
to LTM4676.

Verifying the chip type is getting more complicated with new chips,

MAX20751 is a multiphase power controller with internal buck converter.
It uses VR12.0 to report the output voltage. This requires an explicit

voltage.  This command is not currently supported.

The temperature value of Fintek F81866 is the same with

with 0x6c + 2*(nr+1). We change the rule in f71882fg_probe(),
If type = f71858fg/f8000/f81866a. the temp_start will set to 0,
others are 1.

The F81866 over-temperature beep setting is not the same with

using bit 0/1/2 & 4/5/6, others are using bit 1/2/3 & 5/6/7,

Pull MIPS fixes from Ralf Baechle:
 "Another round of MIPS fixes for 4.2.  No area does particularly stand
  out but we have a two unpleasant ones:

   - Kernel ptes are marked with a global bit which allows the kernel to
     share kernel TLB entries between all processes.  For this to work
     both entries of an adjacent even/odd pte pair need to have the
     global bit set.  There has been a subtle race in setting the other
     entry's global bit since ~ 2000 but it take particularly
     pathological workloads that essentially do mostly vmalloc/vfree to
     trigger this.

     This pull request fixes the 64-bit case but leaves the case of 32
     bit CPUs with 64 bit ptes unsolved for now.  The unfixed cases
     affect hardware that is not available in the field yet.

   - Instruction emulation requires loading instructions from user space
     but the current fast but simplistic approach will fail on pages
     that are PROT_EXEC but !PROT_READ.  For this reason we temporarily
     do not permit this permission and will map pages with PROT_EXEC |
     PROT_READ.

  The remainder of this pull request is more or less across the field
  and the short log explains them well"
