The GIC can work on several interrupt triggers, and the A20 was actually setting it up to use a rising edge as a trigger, while it was actually a level high trigger, leading to some interrupts that would be completely ignored if the edge was missed. Fix this for the remaining DT nodes that slipped through.

This results in getting double the requested clock rates, breaking the display on omap3430 based devices. This got broken when d0f58bd3bba3877fb1af4664c4e33273d36f00e4 and related patches were merged for v3.14, as omapdss driver now relies more on the clk-framework and CLK_SET_RATE_PARENT.

This messages is normally shown when there is an issue when comparing the processor ID (CP15 0, c0, c0) with the values/masks described in proc-v7.S. However, the same message is displayed when LPAE support is enabled in the kernel configuration, but not available in the CPU, after looking at ID_MMFR0 (CP15 0, c0, c1, 4). Having the same error message is highly misleading. This commit improves this by showing a different error message when this situation occurs: Error: Kernel with LPAE support, but CPU does not support LPAE.

The code assumed that a CPU entering idle would actually be powered off, loosing its state entierely, and would then need to be reinitialized. It turns out that this is not always the case, and some HW performs CPU PM without actually killing the core. In this case, we try to reinitialize KVM while it is still live. It ends up badly, as reported by Andre Przywara (using a Calxeda Midway): [ 3.663897] Kernel panic - not syncing: unexpected prefetch abort in Hyp mode at: 0x685760 [ 3.663897] unexpected data abort in Hyp mode at: 0xc067d150 [ 3.663897] unexpected HVC/SVC trap in Hyp mode at: 0xc0901dd0 The trick here is to detect if we've been through a full re-init or not by looking at HVBAR (VBAR_EL2 on arm64). This involves implementing the backend for __hyp_get_vectors in the main KVM HYP code (rather small), and checking the return value against the default one when the CPU notifier is called on CPU_PM_EXIT.
