+	  emlog is a Linux kernel module that makes it easy to access the most
+	  recent (and only the most recent) output from a process. It works
+	  just like "tail -f" on a log file, except that the storage required
+	  never grows. This can be useful in embedded systems where there isn't
+	  enough memory or disk space for keeping complete log files, but the
+	  most recent debugging messages are sometimes needed (e.g., after an
+	  error is observed).

PATCH v2 1/1 emlog: new package

Dear Joris Lijssens,

Changes v1 -> v2:
- use kernel-module infra
- use TARGET_CONFIGURE_OPTS
- add extra comments
- add dependcy on the linux kernel

Applied with a number of extra changes:

[Thomas:
- update to the latest github version, which has a number of fixes/improvements compared to the latest tag.
- add a patch to fix the build of the kernel module with recent kernel versions (>= 3.19).
- use $(INSTALL) -D with a full destination path.
- rewrap Config.in help text, lines were too long.]

Thanks!

Thomas
