6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mike Marciniszyn <redacted>
commit 03769f72d66edab82484449ed594cb6b00ae0223 upstream.
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().
