    [ARM] Make -mcpu=generic schedule for an in-order core (Cortex-A8).
    

This might be a source code problem.

Assign this to the graphics people to have them take a look at this first.

The test fails because 
bs_egl_image_flush_external (eglImageFlushExternalEXT) checks the value of
img->external, which is set by bs_egl_image_create_gbm. 
bs_egl_image_create_gbm calls eglCreateImageKHR, this function does not initialize the value img_external_flush, which can be set by eglp_get_attribute_value_if_present if EGL_IMAGE_EXTERNAL_FLUSH_EXT appears in
the parameter (const EGLint *attrib_list) of function eglCreateImageKHR. In the test, the eglCreateImageKHR is not set in  bs_egl_image_create_gbm, so we just got lucky to have this test passed.

Raise the priority to p1 because this blocks us from rolling the compiler.

drm-tests: specify EGL_IMAGE_EXTERNAL_FLUSH_EXT when creating EGLImage

EGL_IMAGE_EXTERNAL_FLUSH_EXT attribute should be set to EGL_TRUE when
creating an image that supports eglImageFlushExternalEXT.

This breaks the NVIDIA eglCreateImageKHR code since it doesn't recognize
EGL_IMAGE_EXTERNAL_FLUSH_EXT but advertises the extension. Let's
work-around this.
