This patch set contains miscellaneous improvements for the
dell_smm_hwmon driver.
The first two patches allow for testing known SMM code pairs
for automatic fan mode enable/disable without having to
manually edit and recompile the module, which makes testing
easier and is compatible with Secure Boot/Kernel Lockdown.
Because of the later, users cannot specify arbitrary SMM codes,
but are limited to two promising code pairs (for now).
The fifth patch improves the inline assembly code, so
saving/restoring the registers is done by the compiler,
including the flags register. As a side effect, it now works
on both 32 and 64 bit x86, while being faster too.
The remaining patches are smaller improvments.
All patches have been tested on a Dell Inspiron 3505.
