From b0c8ce897a42ab357001f275fa80ba82c8d4555f Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Mon, 27 Mar 2017 19:07:24 +0200 Subject: [PATCH] s390/pci: reduce iomap size (even more) Commit c506fff3d3a8 ("s390/pci: resize iomap") reduced the iomap to NR_FUNCTIONS * PCI_BAR_COUNT elements. Since we only support functions with 64bit BARs we can cut that number in half.
