This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "uClibc-ng - small C library for embedded systems". The branch, master has been updated via 0f541b5c48b7b0df80e2aaa8fdbf653a8b8bcd03 (commit) via a75ca05cf77652bebb01edfb0bc48cd78eab95dc (commit) via 1b49dc96d103e0151fee290d55cea55aa12c906d (commit) from bf70f6f1face8e36030544a74e5ea04903df16cb (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit 0f541b5c48b7b0df80e2aaa8fdbf653a8b8bcd03 Author: Waldemar Brodkorb <wbx@uclibc-ng.org> Date: Sun Jun 12 11:41:23 2016 +0200 xtensa: use generic lowlevellock Simplify and use generic lowlevellock.
