This patch adds some room for CPU-external interrupt controllers in the Linux interrupt space. Until now, only the 32 CPU internal interrupt lines were supported which does not allow for external interrupt controllers such as GPIO modules etc. Signed-off-by: Christian Ruppert <christian.ruppert@abilis.com> Signed-off-by: Pierrick Hascoet <pierrick.hascoet@abilis.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
