+Subject: include/linux/bitops.h: introduce BITS_PER_TYPE
+
+From: Chris Wilson <chris@chris-wilson.co.uk>
+
+commit 9144d75e22cad3c89e6b2ccab551db9ee28d250a upstream.
+
+net_dim.h has a rather useful extension to BITS_PER_BYTE to compute the
+number of bits in a type (BITS_PER_BYTE * sizeof(T)), so promote the macro
+to bitops.h, alongside BITS_PER_BYTE, for wider usage.
