Hi, This series fixes the exception handling on ARM.
First of all, it makes the symbols of the exception vectors relocatable. Then, it ensures that the exception vectors are relocated. To do so, we copy or move the exception vectors depending on the CPU features. In order to handle gracefully CPU features, this commit introduces Kconfig symbols for each ARM processor and it selects through Kconfig the feature HAS_VBAR for the right CPUs. Also, this series configures correctly the IRQ and the FIQ stack pointers. Regards, Georges Changes in v3: - Use the CPU feature HAS_VBAR Kconfig symbol Changes in v2: - Relocate exception vectors also on processors which do not support security extensions - Reword the commit messages Georges Savoundararadj (4): kconfig: arm: introduce symbol for ARM CPUs arm: make .vectors section allocatable arm: relocate the exception vectors arm: interrupt_init: set sp in IRQ/FIQ modes arch/arm/Kconfig | 209 +++++++++++++++++++++++++++++++ arch/arm/cpu/arm926ejs/davinci/Kconfig | 3 -
