These probably shouldn't have been committed to SLOF without the corresponding qemu code being at least acked in principle. After all, the qemu source is effectively the authoritative source for what the vendor specific hcalls are. > --- > lib/libhvcall/libhvcall.h | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/lib/libhvcall/libhvcall.h b/lib/libhvcall/libhvcall.h > index b2ea3f6..193b738 100644 > --- a/lib/libhvcall/libhvcall.h > +++ b/lib/libhvcall/libhvcall.h > @@ -25,6 +25,8 @@ > /* Client Architecture support */ > #define KVMPPC_H_CAS (KVMPPC_HCALL_BASE + 0x2) > #define KVMPPC_H_RTAS_UPDATE (KVMPPC_HCALL_BASE + 0x3) > +#define KVMPPC_H_REPORT_MC_ERR (KVMPPC_HCALL_BASE + 0x4) > +#define KVMPPC_HCALL_MAX KVMPPC_H_NMI_MCE > > #ifndef __ASSEMBLY__ >

KVMPPC_H_NMI_MCE isn't defined anywhere. We should have: #define KVMPPC_HCALL_MAX KVMPPC_H_RTAS_UPDATE > #ifndef __ASSEMBLY__ >

This reverts commit 089fc18a9b "libhvcall: drop unused KVMPPC_H_REPORT_MC_ERR and KVMPPC_H_NMI_MCE defines" as a bigger hammer is coming soon which will pass the entire device tree to QEMU, not just phandles. QEMU has never used the hcall this patch is removing so there will be no compatibility issues.
