We were storing viewport relative coordinates for AVIVO/DCE display engines. However, radeon_crtc_cursor_set2 and radeon_cursor_reset pass radeon_crtc->cursor_x/y as the x/y parameters of radeon_cursor_move_locked, which would break if the CRTC isn't located at (0, 0).

GUI idle interrupts should be enabled only after we have enabled coarse grain clock gating (CGCG). This prevents GFX engine generating idle interrupt even though CGCG is not completely enabled. Most of the time this goes un-noticed, but on some Stoney ASICs this results in GFX engine hang after system resumes from suspend. The issue is not particular to Stoney though and could have occured on any ASIC. The patch fixes this issue. Reviewed-by:

Commit aeefb368 ("drm/exynos: gsc: add device tree support and remove usage of static mappings") made the DRM_EXYNOS_GSC Kconfig symbol to only be selectable if the exynos-gsc V4L2 driver isn't enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_EXYNOS_GSC which is not correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_EXYNOS_GSC=y but will evaluate to 'm' if VIDEO_SAMSUNG_EXYNOS_GSC=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which isn't what we want since otherwise 2 drivers could attempt to use the hardware at the same time.

It is not entirely clear why only 1303 pages have been scanned during that time (maybe there was a heavy IRQ activity interfering). In any case it looks like we can really hit long periods without scheduling on non preemptive kernels so an explicit cond_resched() in shrink_node_memcg which is independent on the reclaim operation is due.

When building a specific target such as bzImage, modules aren't normally built. However if CONFIG_TRIM_UNUSED_KSYMS is enabled, no built modules means none of the exported symbols are used and therefore they will all be trimmed away from the final kernel. A subsequent "make modules" will fail because modpost cannot find the needed symbols for those modules in the kernel binary. Let's make sure modules are also built whenever CONFIG_TRIM_UNUSED_KSYMS is enabled and that the kernel binary is properly rebuilt accordingly. Signed-off-by:
