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
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...
This doesn't tell me which patches to apply now. The first two ?
Yes, 1/6 and 2/6 are OK.
Guenter, now you can apply whole series + add all tested-by lines from
email threads. Looks like it is OK now.
First three patches applied and sent to Linus last night.
Remaining three patches applied to -next.
Thanks,
Guenter
