I'm sending all my dell-smm-hwmon patches in one series, because

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 Rohár (6):
hwmon: (dell-smm) Fail in ioctl I8K_BIOS_VERSION when bios

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...
This doesn't tell me which patches to apply now. The first two ?
