x86, cpufeature: Rename X86_FEATURE_DTS to X86_FEATURE_DTHERM

2012-07-16T16:04:22+00:00

commit 4ad33411308596f2f918603509729922a1ec4411 upstream.

It makes sense to label "Digital Thermal Sensor" as "DTS", but
unfortunately the string "dts" was already used for "Debug Store", and
/proc/cpuinfo is a user space ABI.

Therefore, rename this to "dtherm".

This conflict went into mainline via the hwmon tree without any x86
maintainer ack, and without any kind of hint in the subject.

hwmon: (coretemp) Increase CPU core limit

2012-05-01T16:16:14+00:00

CPU core ID is used to index the core_data[] array. The core ID is, however, not
sequential; 10-core CPUS can have a core ID as high as 25. Increase the limit to
32 to be able to deal with current CPUs.

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.
