+Subject: [PATCH 1/5] fix for pipe() on sparc
+
+When using something like this:
+ $ echo foo|grep foo|wc -l
+with mksh shell, you get an runtime error.
+
+Glibc and klibc does not do these extra check.
+After removing this check using double pipes work fine.
+Tested with Qemu 2.1.0.

+Subject: [PATCH 2/5] Revert "sparc: use HIDDEN_JUMPTARGET for errno"
+
+This reverts commit f51fb26dbcceee9e48d10facc830bd4a549f6cc2.
+
+This fixes linking error for sparc build.
+While building a sparc system you get following linking error:
+libc/sysdeps/linux/sparc/pipe.S:54: undefined reference to `__GI___errno_location'
+
+Removing the HIDDEN_JUMPTARGET fixes the issue, while using gcc 4.8.3/binutils 2.24.
+
+The definition of __errno_location was changed recently here:
+http://git.uclibc.org/uClibc/commit/?id=8f550715c2b211036fc273add3cb5219397ed312
