that fixed the build failure on 32-bit, but there's another one i just
hit on 64-bit x86:
drivers/built-in.o: In function `acpi_video_bus_put_devices':
video.c:(.text+0x5540d): undefined reference to
`thermal_cooling_device_unregister'
drivers/built-in.o: In function `acpi_video_bus_add':
video.c:(.text+0x56994): undefined reference to
`thermal_cooling_device_register'
which is due to:
commit 702ed512de9c8a67a69a981c73b7337c2131f198
Date: Thu Jan 17 15:51:22 2008 +0800
ACPI: register ACPI Video LCD as generic thermal cooling device
the commit couldnt be reverted cleanly, i've done a manual fixup of the
revert (find the patch below).
but i suspect the third "generic thermal cooling device" patch might be
broken too:
commit d9460fd227ed2ce52941b6a12ad4de05c195f6aa
Date: Thu Jan 17 15:51:23 2008 +0800
ACPI: register ACPI Processor as generic thermal cooling device
so i've preventively reverted that too, to keep x86-qa running. (that
reverts cleanly without manual merging)
