+Subject: [PATCH] Allow building with newer glibc versions
+
+Newer glibc versions does not include sys/sysmacros.h from sys/types.h
+anymore.  Including it unconditionally should be safe.
+
+See https://sourceware.org/ml/libc-alpha/2015-11/msg00253.html for why
+this was done.

+Subject: [PATCH] Fix linking for non-host compatible targets
+
+Without this, gummiboot build system will use host 'ld' when linking
+target binary, which is obviously not a good idea.

+	  gummiboot is a simple UEFI boot manager which executes
+	  configured EFI images. The default entry is selected by a
+	  configured pattern (glob) or an on-screen menu.
+
+	  gummiboot operates on the EFI System Partition (ESP)
+	  only. Configuration file fragments, kernels, initrds, other
+	  EFI images need to reside on the ESP. Linux kernels need to
+	  be built with CONFIG_EFI_STUB to be able to be directly
+	  executed as an EFI image.
+
+	  See the Grub2 help text for details on preparing an EFI
+	  capable disk image using Gummiboot: the instructions are
+	  exactly the same, except that the Gummiboot configuration
+	  files will be located in /loader/ inside the EFI partition.
