Subject: NTB: Correct Number of Scratch Pad Registers
From: Jon Mason <jon.mason@xxxxxxxxx>
commit 87034511519815259e37336f52edf06d114d43b6 upstream.
The NTB Xeon hardware has 16 scratch pad registers and 16 back-to-back
scratch pad registers. Correct the #define to represent this and update
the variable names to reflect their usage.
