Ugh, this patch wasn't even build tested, on 64-bit allyes/allmodconfig:
arch/x86/hyperv/hv_apic.c: In function ‘__send_ipi_mask’:
arch/x86/hyperv/hv_apic.c:171:4: error: label ‘ipi_mask_done’ used but not defined
scripts/Makefile.build:317: recipe for target 'arch/x86/hyperv/hv_apic.o' failed
make[2]: *** [arch/x86/hyperv/hv_apic.o] Error 1
Thanks,
Ingo
