First two patches fixes problem with old /proc/i8k file. Second is
security fix and should be backported to all stable kernels (that
problem was there always). I tested i8kctl tool (from i8kutils
package) that it still works with these patches. Without root
access for those security operations just showes '?' or '-1'.
Third and fourth patches try to fix problem on machines with broken
SMM/BIOS when calling function fan_type().
Fifth is new feature and last sixth useful for debugging.
Pali RohÃr (6):
hwmon: (dell-smm) Fail in ioctl I8K_BIOS_VERSION when bios
version is
not a number
hwmon: (dell-smm) Restrict fan control and serial number to
CAP_SYS_ADMIN by default
hwmon: (dell-smm) Disallow fan_type() calls on broken machines
hwmon: (dell-smm) Cache fan_type() calls and change fan
detection hwmon: (dell-smm) Detect fan with index=2
hwmon: (dell-smm) In debug mode log duration of SMM calls

Pali,
You asked for additional testing, so I am not sure what you expect me
to do.
Which of the patches can/should I apply now ?
Guenter
Test 3/6 and 4/6 patches on affected Dell machines. I CCed all people
who tried to debug those bugs, so need confirmation from them that after
applying 3/6 and 4/6 patches, erratic fan behaviour is not there...
But because those two patches depends on previous, it is needed to test
whole series...
