2010-11-02drm/i915: Fix the graphics frequency clamping at init and when IPS is active.Jesse Barnes
Part of the issue here was that Eric slipped in a debug hack for testing the i915 IPS code before the intel_ips.c driver had landed. This caused the driver to always use the full range of frequencies, which is only legal when IPS tells us we have the headroom. Once that hack was removed, there was confusion about the driver's frequency clamping variables: max_delay is the driver's current limit on the highest frequency the IPS driver wants us to use, while dev_priv->fmax is the hardware-reported limit that the IPS driver can increase up to. Tested with IPS driver loaded or not. Note that on Ironlake systems without the IPS driver loaded this will result in a performance reduction, and the inital warmup of frequency limits can impact benchmarking on systems with IPS loaded.

2010-10-28drm/i915: Flush read-only buffers from the active list upon idle as wellChris Wilson
It is possible for the active list to only contain a read-only buffer so that the ring->gpu_write_list remains entry. This leads to an inconsistency between i915_gpu_is_active() and i915_gpu_idle() causing an infinite spin during the shrinker and an assertion failure that i915_gpu_idle() does indeed flush all buffers from the active lists.

2010-10-26mm: stack based kmap_atomic()Peter Zijlstra
Keep the current interface but ignore the KM_type and use a stack based approach. The advantage is that we get rid of crappy code like: #define __KM_PTE \ (in_nmi() ? KM_NMI_PTE : \ in_irq() ? KM_IRQ_PTE : \ KM_PTE0) and in general can stop worrying about what context we're in and what kmap slots might be appropriate for that. The downside is that FRV kmap_atomic() gets more expensive. For now we use a CPP trick suggested by Andrew: #define kmap_atomic(page, args...) __kmap_atomic(page) to avoid having to touch all kmap_atomic() users in a single patch.
