+ * we're stuck with it for ABI compatability reasons.
+ *
+ * For a 32-bit consumer inspecting a 32-bit task, then it will look at

+ * These correspond directly to a prefix of the registers saved in our
+ * 'struct pt_regs', with the exception of the PC, so we copy that down
+ * (x15 corresponds to SP_hyp in the architecture).
+ *
+ * So far, so good.
+ *
+ * The oddity arises when a 64-bit consumer looks at a 32-bit task and
+ * asks for registers beyond PERF_REG_ARM_MAX. In this case, we return
+ * SP_usr, LR_usr and PC in the positions where the AArch64 SP, LR and
+ * PC registers would normally live. The initial idea was to allow a
+ * 64-bit unwinder to unwind a 32-bit task and, although it's not clear
+ * how well that works in practice, somebody might be relying on it.
+ *
+ * At the time we make a sample, we don't know whether the consumer is
