From 926c1c7a8f2ec08a0d100ed48a845a76271192da Mon Sep 17 00:00:00 2001 From: Mike Marciniszyn Date: Wed, 29 Nov 2023 14:21:43 -0600 Subject: [PATCH] RDMA/irdma: Fix support for 64k pages [ Upstream commit 03769f72d66edab82484449ed594cb6b00ae0223 ] Virtual QP and CQ require a 4K HW page size but the driver passes PAGE_SIZE to ib_umem_find_best_pgsz() instead. Fix this by using the appropriate 4k value in the bitmap passed to ib_umem_find_best_pgsz().
