Subject: [PATCH RESEND] irq: export irq_check_status_bit symbol

Because of the missing export symbol for irq_chekc_status_bit,
Building arm_spe_pmu.ko is a failure on the modpost step.

Below is an error message I saw:
ERROR:modpost: "irq_check_status_bit" [drivers/perf/arm_spe_pmu.ko] undefined!
make[4]: *** [scripts/Makefile.modpost:111: Module.symvers] Error 1
make[4]: *** Deleting file 'Module.symvers'
make[3]: *** [Makefile:1396: modules] Error 2
make[2]: *** [debian/rules:7: build-arch] Error 2
dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
make[1]: *** [scripts/Makefile.package:83: bindeb-pkg] Error 2
