hwmon: (fam15h_power) Tweak runavg_range on resume

2012-10-10T02:31:04+00:00

commit 5f0ecb907deb1e6f28071ee3bd568903b9da1be4 upstream.

The quirk introduced with commit
00250ec90963b7ef6678438888f3244985ecde14 (hwmon: fam15h_power: fix
bogus values with current BIOSes) is not only required during driver
load but also when system resumes from suspend. The BIOS might set the
previously recommended (but unsuitable) initilization value for the
running average range register during resume.

hwmon: (twl4030-madc-hwmon) Initialize uninitialized structure elements

2012-09-19T14:05:21+00:00

commit 73d7c119255615a26070f9d6cdb722a166a29015 upstream.

twl4030_madc_conversion uses do_avg and type structure elements of
twl4030_madc_request. Initialize structure to avoid random operation.

Fix for: Coverity CID 200794 Uninitialized scalar variable.

hwmon: (asus_atk0110) Add quirk for Asus M5A78L

2012-09-19T14:04:29+00:00

commit 43ca6cb28c871f2fbad10117b0648e5ae3b0f638 upstream.

The old interface is bugged and reads the wrong sensor when retrieving
the reading for the chassis fan (it reads the CPU sensor); the new
interface works fine.

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

2012-08-04T15:31:12+00:00

commit 141168c36cdee3ff23d9c7700b0edc47cb65479f and
commit 3f806e50981825fa56a7f1938f24c0680816be45 upstream.

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: (it87) Preserve configuration register bits on init

2012-07-25T03:11:17+00:00

commit 41002f8dd5938d5ad1d008ce5bfdbfe47fa7b4e8 upstream.

We were accidentally losing one bit in the configuration register on
device initialization. It was reported to freeze one specific system
right away. Properly preserve all bits we don't explicitly want to
change in order to prevent that.

x86, cpufeature: Rename X86_FEATURE_DTS to X86_FEATURE_DTHERM

2012-07-04T04:44:28+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: (applesmc) Limit key length in warning messages

commit ac852edb47b15900886ba2564eeeb13b3b526e3e upstream.

Key lookups may call read_smc() with a fixed-length key string,
and if the lookup fails, trailing stack content may appear in the
kernel log. Fixed with this patch.

hwmon: (fam15h_power) Increase output resolution

2012-06-19T22:18:06+00:00

On high CPU load the accumulating values in the running_avg_cap
register are very low (below 10), so averaging them too early leads
to unnecessary poor output resolution. Since we pretend to output
micro-Watt we better keep all the bits we have as long as possible.
