 linux (4.7.5-2) UNRELEASED; urgency=medium
 
+  [ Ben Hutchings ]
   * debian/bin/gencontrol.py: Fix cross-build-dependencies if invoked under
     dpkg-buildpackage
   * linux-image: Exclude vmlinux from stripping by dh_strip (fixes FTBFS
     on hppa)
 
+  [ Cyril Brulebois ]
+  * Add nls_ascii to the fat-modules udeb, following the change of
+    iocharset default in 4.7.2-1. This fixes a regression with EFI-related
+    mounts within the Debian Installer.
