+From 9a18df7a71bfa620b1278777d64783a359d7eb4e Mon Sep 17 00:00:00 2001
+From: Thorsten Glaser <tg@mirbsd.org>
+Date: Sun, 4 May 2014 01:37:54 +0200
+Subject: [PATCH] mount tmpfs-as-rootfs (initramfs) with -o
+ nr_blocks=0,nr_inodes=0
+
+I would have preferred to write this patch to be able to pass
+rootflags=nr_blocks=0,nr_inodes=0 on the kernel command line,
+and then hand these rootflags over to the initramfs (tmpfs)
+mount in the same way the kernel hands them over to the block
+device rootfs mount. But at least the Debian/m68k initrd also
+parses $rootflags from the environment and adds it to the call
+to the user-space mount for the eventual root device, which
+would make the kernel command line rootflags option be used in
+both places (tmpfs and e.g. ext4) which is guaranteed to error
+out in at least one of them.
+
+This change is intended to aid people in a setup where the
+initrd is the final root filesystem, i.e. not mounted over.
+This is especially useful in automated tests running on qemu
+for boards with constrained memory (e.g. 64 MiB on sh4).
+
+Considering that the initramfs is normally emptied out then
+overmounted, this change is probably safe for setups where
+initramfs just hosts early userspace, too, since the tmpfs
+backing it is not accessible any more later on, AFAICT.
