[PATCH] radeon: Use Linux division macro in si_calculate_leakage_for_v_and_t_formula

[PATCH] radeon: Use Linux division macro in si_calculate_leakage_for_v_and_t_formula

[Andi Kleen]

From: Andi Kleen <ak@linux.intel.com>

This fixes my 32bit build which failed with:

drivers/built-in.o: In function
`si_calculate_leakage_for_v_and_t_formula':
/home/ak/lsrc/git/linux-2.6/drivers/gpu/drm/radeon/si_dpm.c:1770:
undefined reference to `__divdi3'
