The patch titled
Subject: dmi_scan: proper buf type in dmi_present()
has been removed from the -mm tree. Its filename was
dmi_scan-refactor-dmi_scan_machine-smbiosdmi_present-fix.patch
This patch was dropped because it was folded into dmi_scan-refactor-dmi_scan_machine-smbiosdmi_present.patch

From: Artem Savkov <artem.savkov@xxxxxxxxx>
Subject: dmi_scan: proper buf type in dmi_present()
buf needs to be unsigned in dmi_present(), otherwise dmi_base calculation
doesn't work properly leading to a wraparound during dmi_ioremap:
