Hi Stephen Rothwell:

Thank you very much for your feedback.
I think the following modification can solve the compilation problem of ppc64.
I have verified it on the x86 cross environment,
and I will incorporate the modification into the next version of patch.

#define kvm_trace_symbol_iocsr \
-       ({ KVM_TRACE_IOCSR_READ_UNSATISFIED, "unsatisfied-read" }, \
+       { KVM_TRACE_IOCSR_READ_UNSATISFIED, "unsatisfied-read" }, \
        { KVM_TRACE_IOCSR_READ, "read" }, \
-       { KVM_TRACE_IOCSR_WRITE, "write" })
+       { KVM_TRACE_IOCSR_WRITE, "write" }

Thanks,
Xianglai.

Hi all,

After merging the loongarch tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
