+Subject: [PATCH 01/12] qemu: Add addition environment space to boot loader
+ qemu-system-mips
+
+Upstream-Status: Inappropriate - OE uses deep paths
+
+If you create a project with very long directory names like 128 characters
+deep and use NFS, the kernel arguments will be truncated. The kernel will
+accept longer strings such as 1024 bytes, but the qemu boot loader defaulted
+to only 256 bytes. This patch expands the limit.
