#     drm/ttm: fix type mismatch error on sparc64
#     
#     On sparc64, __fls() returns an "int", but the drm TTM code expected it
#     to be "unsigned long" as on x86.  As a result, on sparc (and arc, and
#     m68k) you get build errors because 'min()' checks that the types match.
#     
#     As suggested by Linus, it can use min_t instead of min to force the type
#     to be "unsigned int".
