From 85665c9816a2b38866e03c019bf5c2e47eb9fb04 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Sat, 16 Apr 2005 15:26:18 -0700 Subject: [PATCH] IB/mthca: allocate correct number of doorbell pages Doorbell record pages are allocated in HCA page size chunks (always 4096 bytes), so we need to divide by 4096 and not PAGE_SIZE when figuring out how many pages we'll need space for.
