2012-02-03ARM: Make the sched_clock framework mandatoryMarc Zyngier
All sched_clock() providers have been converted to the sched_clock framework, which also provides a jiffy based implementation for the platforms that do not provide a counter. It is now possible to make the sched_clock framework mandatory, effectively preventing new platforms to add new sched_clock() functions, which would be detrimental to the single zImage work.

2012-02-03ARM: prima2: convert to common sched_clock() implementationMarc Zyngier
Prima2 has its own sched_clock() implementation, which gets in the way of a single zImage. Moving to the common sched_clock framework makes the code slightly cleaner (the mapping hack in sched_clock() goes away...).

2012-01-25ARM: 7300/1: realview: fix definition of GPIO0 interrupt on PB1176 to match TRMWill Deacon
Currently, -1 is used as the GPIO0 interrupt on realview PB1176 and an AMBA device is registered with this parameter. With the pending NO_IRQ cleanup, this will lead to a warning at boot time, since -1 is obviously broken. This patch updates the interrupt used for GPIO0 to match that specified by the TRM. Unfortunately, it's not clear how to trigger this interrupt so we trust that the documentation is correct.
