We are doing this for all platforms over time, because this is one of the requirements for building a multiplatform kernel, and generally a good idea. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIVAwUAUA2dgGCrR//JCVInAQJOJRAA4xWh3CUqpuJ13yk2tOBcGU9+orer93fP U3DAG6jJ75blQzfA9wBoWPjqFhJo76ZtLFA9comkGI4vH8nTNNbXr1ZNt2/PjOGS PqZIYJk/f5QqOzCd10V5bK4EVFR/mjvQ8sBP8qfaHII0GVPomfa8jnXnFnLFjreX hhucTCf4z2HBvIjfOiilPtJbFpdrQ9oquM4W4Go1lrMZMU8B+Z3ClqytoxYW2Bw3 uQ0EzFlAwaXZ1CMcDn4eQJxNt8dO4SbGI7AHd3HmW3tFaaJC9dpey/7pIoW3gyz8 2e3wrdHXCAYq3sUlwzIrROCcBfW502E+KUmDi8ePT7zgZmxAmrqRCTNEqwaaGYrS Q/mk+Kpnjvtl6w21ss1LxNHP18TNL/f8isYW9vUQG8yogWlVin6NhPvNQXDDBWoD lfAyeL5JSoVxVGxft8EhLI/inPKBnWe2heE+zrRGQzUhTuUSyspmwK6o3b7JYNTX 16fY6OhW90CaZm6r1yKZsiE96Dd63oL4OVFELsgPQdsBNdWeKmOjs6fq46Bp0Hdf SAQ543yabPkDr4ZanaNqo0s3Vu2xVnvBS4FR0gbx6+LGuagkmBpSkYnlhgNJBbdK 6D5GCRoX0ayzJvg29kKzek2h8NhGtDco4dr7K5Hl9NebeZ++CjZ7xTbFQN6olt+D 8CcIdD2J0PY= =Y2Sm -----END PGP SIGNATURE----- Merge tag 'irq' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull arm-soc sparse IRQ conversion from Arnd Bergmann: "The I.MX platform is getting converted to use sparse IRQs.
