Currently, the firmware tables are parsed by the the virtual timer and virtual GIC code in order to configure them correctly. However the parsing of these tables is already done in the GIC and arch timer drivers. This patch series introduces new helpers to retrieve the information from the different drivers in order to avoid duplication of the parsing code. To make the merge easier via the different trees, each patch modifies a single subsystem. The suggested plan to merge the series is divided in 3 steps: 1) Patches #1-#2 are merged via the clocksource tree Patches #2-#6 are merged via the irqchip tree 2) Patches #7-#8 are merge via the KVM tree 3) Patch #9 is merged via the clocksource tree. For all the changes see in each patch.
