For the moment, manually cutting & pasting patchtest results:
* Issue Added patch file is missing Upstream-Status in the
header [test_upstream_status_presence]
Suggested fix Add Upstream-Status: <status> to the header of
meta/recipes-devtools/go/go-1.4/0001-cmd-ld-set-alignment-for-the-.rel.plt-section-on-32-.patch (possible values: Pending, Submitted, Accepted, Backport, Denied, Inappropriate)
* Issue A patch file has been added, but does not have a
Signed-off-by tag [test_signed_off_by_presence]
Suggested fix Sign off the added patch file
(meta/recipes-devtools/go/go-1.4/0001-cmd-ld-set-alignment-for-the-.rel.plt-section-on-32-.patch)

> +SUMMARY = "Go programming language compiler"
> +DESCRIPTION = " The Go programming language is an open source project to make \
> + programmers more productive. Go is expressive, concise, clean, and\
> + efficient. Its concurrency mechanisms make it easy to write programs\
> + that get the most out of multicore and networked machines, while its\
> + novel type system enables flexible and modular program construction.\
> + Go compiles quickly to machine code yet has the convenience of\
> + garbage collection and the power of run-time reflection. It's a\
> + fast, statically typed, compiled language that feels like a\
> + dynamically typed, interpreted language."
