Unbreak the DRM menu. This Kconfig symbol does not depend on DRM, so the menu is broken at that point. Move the symbol to a location in the Kconfig file so that it does not break the dependency continuity.

We try hard to select a suitable hole in the drm_mm first time. But if that is unsuccessful, we then have to look at neighbouring nodes, and this requires traversing the rbtree. Walking the rbtree can be slow (much slower than a linear list for deep trees), and if the drm_mm has been purposefully fragmented our search can be trapped for a long, long time. For non-preemptible kernels, we need to break up long CPU bound sections by manually checking for cond_resched(); similarly we should also bail out if we have been told to terminate. (In an ideal world, we would break for any signal, but we need to trade off having to perform the search again after ERESTARTSYS, which again may form a trap of making no forward progress.)

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

The wait_for macro's for Broadcom V3D driver used msleep, which is inappropriate due to its inaccuracy at low values (minimum wait time is about 30ms on the Raspberry Pi). This sleep was triggering in v3d_clean_caches(), causing us to only be able to dispatch ~33 compute jobs per second. This patch replaces the macro with the one from the Intel i915 version which uses usleep_range to provide more accurate waits. v2: Split from the vc4 patch so that we can confidently apply to stable (by anholt) Signed-off-by:James Hughes <james.hughes@raspberrypi.com> Signed-off-by:
