++ * we're stuck with it for ABI compatability reasons.
++ *
++ * For a 32-bit consumer inspecting a 32-bit task, then it will look at
++ * the first 16 registers (see arch/arm/include/uapi/asm/perf_regs.h).
++ * 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
++ * 32-bit or 64-bit, so we have to cater for both possibilities.
