+Subject: [PATCH 3/4] powerpc/64s: Add workaround for P9 vector CI load issue
+
+POWER9 DD2.1 and earlier has an issue where some cache inhibited
+vector load will return bad data. The workaround is two part, one
+firmware/microcode part triggers HMI interrupts when hitting such
+loads, the other part is this patch which then emulates the
+instructions in Linux.
+
+The affected instructions are limited to lxvd2x, lxvw4x, lxvb16x and
+lxvh8x.
+
+When an instruction triggers the HMI, all threads in the core will be
+sent to the HMI handler, not just the one running the vector load.
+
+In general, these spurious HMIs are detected by the emulation code and
+we just return back to the running process. Unfortunately, if a
+spurious interrupt occurs on a vector load that's to normal memory we
+have no way to detect that it's spurious (unless we walk the page
+tables, which is very expensive). In this case we emulate the load but
+we need do so using a vector load itself to ensure 128bit atomicity is
+preserved.
+
+Some additional debugfs emulated instruction counters are added also.
