PATCH 2/2 Oprofile support
This adds the necessary architecture code to run oprofile on AVR32 using the performance counters documented by the AVR32 Architecture Manual.
---
Mathieu, I want to get oprofile support queued up for 2.6.25, and since I don't see any signs that the Kconfig.instrumentation removal patches are going in any time soon, I'm going to turn things around and apply these two patches to my tree.
This unfortunately means that your patch won't apply cleanly to -mm anymore, but it'll hopefully be easy to fix. When you do, please add ARCH_SUPPORTS_OPROFILE to arch/avr32/Kconfig as well.

PATCH 1/1 Fix AVR32 for instrumentation menu removal
Quoting : Haavard Skinnemoen <[email protected]>
Mathieu, I want to get oprofile support queued up for 2.6.25, and since I don't see any signs that the Kconfig.instrumentation removal patches are going in any time soon, I'm going to turn things around and apply these two patches to my tree.
This unfortunately means that your patch won't apply cleanly to -mm anymore, but it'll hopefully be easy to fix. When you do, please add ARCH_SUPPORTS_OPROFILE to arch/avr32/Kconfig as well.
Me:
This patch fixes the changes made by [PATCH 2/2] [AVR32] Oprofile support so the instrumentation removal patch applies correctly.
Should be applied after "[PATCH 2/2] [AVR32] Oprofile support", but before the instrumentation menu removal patches.
