Pull hwmon changes for v3.4 from Guenter Roeck:
 "Mostly cleanup.  No new drivers this time around, but support for
  several chips added to existing drivers: TPS40400, TPS40422, MTD040,
  MAX34446, ZL9101M, ZL9117M, and LM96080.  Also, added watchdog support
  for SCH56xx, and additional attributes for a couple of drivers."

hwmon: (coretemp) Add missing section annotations

2012-01-16T21:51:47+00:00

Many functions in the coretemp driver lack a proper section
annotation. Add them to let the kernel free the memory after
initialization when possible.

x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86'

2011-12-21T08:25:09+00:00

Several fields in struct cpuinfo_x86 were not defined for the
!SMP case, likely to save space.  However, those fields still
have some meaning for UP, and keeping them allows some #ifdef
removal from other files.  The additional size of the UP kernel
from this change is not significant enough to worry about
keeping up the distinction:

	   text    data     bss     dec     hex filename
	4737168	 506459	 972040	6215667	 5ed7f3	vmlinux.o.before
	4737444	 506459	 972040	6215943	 5ed907	vmlinux.o.after

for a difference of 276 bytes for an example UP config.

If someone wants those 276 bytes back badly then it should
be implemented in a cleaner way.

hwmon: (coretemp) Fix for non-SMP builds

2011-11-06T19:25:18+00:00

The definition of TO_ATTR_NO in the non-SMP case is wrong. As the SMP
definition resolves to the correct value, just use this for both
cases.

Without this fix the temperature attributes are named temp0_* instead
of temp2_*, so libsensors won't pick them. Broken since kernel 3.0.

coretemp: Get microcode revision from cpu_data

2011-10-14T11:16:42+00:00

Now that the ucode revision is available in cpu_data remove
the existing code in coretemp.c to query it manually. Read the
ucode revision from cpu_data instead

hwmon: (coretemp) Avoid leaving around dangling pointer

2011-09-28T15:19:21+00:00

Storing the struct temp_data pointer allocated from create_core_data()
when returning an error has the potential of leaving around a pointer
to freed memory. Reset it to NULL for error returns.

hwmon: (coretemp) Fixup platform device ID change

2011-09-28T15:19:20+00:00

With recent change "hwmon: (coretemp) don't use kernel assigned CPU
number as platform device ID", the microcode check is now running on
random CPU. Fix that by checking the microcode before creating the
platform device rather than at probe time.

Also avoid calling TO_PHYS_ID(cpu) twice in the same function, it's
expensive.

hwmon: (coretemp) remove struct platform_data * parameter from create_core_data()

2011-09-23T17:39:11+00:00

The only caller of the function obtained the pointer solely for the
purpose of passing it to this function, while it can be easily
determined from the struct platform_device * parameter also passed.
