acpi_{ac,lid,thermal}: avoid SMAP related KDLs.

While these three worked just fine on my old Atom N450 based netbook,
all caused:

"PANIC: SMAP violation user-mapped address [...] touched from kernel [...]"

on a newer netbook with a Celeron N4020 CPU, before this change.

Side note / drivers status:

- acpi_ac works pretty decently on both machines.
- acpi_lid wrongly returns 0 until you close the lid for the first time.
Reports correct values after that, but seems to cause power_daemon's
event loop thread to peg one core to 100%.
- acpi_thermal readings are a mixed bag. Critical temp values Seem OK on
both machines. Current value generally OK on the older machine, very wrong
on the newer (reports 429496728.6 C).
