Instead of having some special stack frame when first scheduling new thread and a new thread entry wrapper to pull out the needed data, we can reuse the context restore code by adapting the initial stack frame. This reduces the lines of code and simplify the code at the expense of a slightly bigger initial stack frame. Signed-off-by: Carlo Caione <ccaione@baylibre.com>
