I'm sending all my dell-smm-hwmon patches in one series, because due to
changes in code other patches depends on previous.
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 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 ?
