MIPS: Fix build error when SMP is used without GIC

hauke · ralfbaechle · commit 7a50e4688dab · 2016-03-13T10:56:48.000+01:00
The MIPS_GIC_IPI should only be selected when MIPS_GIC is also selected, otherwise it results in a compile error. smp-gic.c uses some functions from include/linux/irqchip/mips-gic.h like plat_ipi_call_int_xlate() which are only added to the header file when MIPS_GIC is set. The Lantiq SoC does not use the GIC, but supports SMP. The calls top the functions from smp-gic.c are already protected by some #ifdefs The first part of this was introduced in commit 72e2014 ("MIPS: Move GIC IPI functions out of smp-cmp.c") Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Cc: Paul Burton <paul.burton@imgtec.com> Cc: stable@vger.kernel.org # v3.15+ Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/12774/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
