+ * the reserved page
+ *
+ *   SAL reserves one page of memory per partition for XPC. Though a full page
+ *   in length (16384 bytes), its starting address is not page aligned, but it
+ *   is cacheline aligned. The reserved page consists of the following:
+ *
+ *   reserved page header
+ *
+ *     The first cacheline of the reserved page contains the header
+ *     (struct xpc_rsvd_page). Before SAL initialization has completed,
+ *     SAL has set up the following fields of the reserved page header:
+ *     SAL_signature, SAL_version, partid, and nasids_size. The other
+ *     fields are set up by XPC. (xpc_rsvd_page points to the local
+ *     partition's reserved page.)
+ *
+ *   part_nasids mask
+ *   mach_nasids mask
+ *
+ *     SAL also sets up two bitmaps (or masks), one that reflects the actual
+ *     nasids in this partition (part_nasids), and the other that reflects
+ *     the actual nasids in the entire machine (mach_nasids). We're only
+ *     interested in the even numbered nasids (which contain the processors
+ *     and/or memory), so we only need half as many bits to represent the
+ *     nasids. The part_nasids mask is located starting at the first cacheline
+ *     following the reserved page header. The mach_nasids mask follows right
+ *     after the part_nasids mask. The size in bytes of each mask is reflected
+ *     by the reserved page header field 'nasids_size'. (Local partition's
+ *     mask pointers are xpc_part_nasids and xpc_mach_nasids.)
+ *
+ *   vars
+ *   vars part
+ *
+ *     Immediately following the mach_nasids mask are the XPC variables
+ *     required by other partitions. First are those that are generic to all
+ *     partitions (vars), followed on the next available cacheline by those
+ *     which are partition specific (vars part). These are setup by XPC.
+ *     (Local partition's vars pointers are xpc_vars and xpc_vars_part.)

+ * ADDROFF(name)
+ *   LOAD_REG_ADDRBASE loads part of the address of label 'name' into
+ *   register 'rn'.  ADDROFF(name) returns the remainder of the address as
+ *   a constant expression.  ADDROFF(name) is a signed expression < 16 bits
+ *   in size, so is suitable for use directly as an offset in load and store
+ *   instructions.  Use this when loading/storing a single word or less as:
+ *      LOAD_REG_ADDRBASE(rX, name)
+ *      ld	rY,ADDROFF(name)(rX)

+ * I/O INTERFACE between SPI controller and protocol drivers

+ * Protocol drivers use a queue of spi_messages, each transferring data
+ * between the controller and memory buffers.
+ *
+ * The spi_messages themselves consist of a series of read+write transfer
+ * segments.  Those segments always read the same number of bits as they
+ * write; but one or the other is easily ignored by passing a null buffer
+ * pointer.  (This is unlike most types of I/O API, because SPI hardware
+ * is full duplex.)
+ *
+ * NOTE:  Allocation of spi_transfer and spi_message memory is entirely
+ * up to the protocol driver, which guarantees the integrity of both (as
+ * well as the data buffers) for as long as the message is queued.
+ */
+
+/**
+ * struct spi_transfer - a read/write buffer pair
+ * @tx_buf: data to be written (dma-safe memory), or NULL
+ * @rx_buf: data to be read (dma-safe memory), or NULL
+ * @tx_dma: DMA address of tx_buf, if spi_message.is_dma_mapped
+ * @rx_dma: DMA address of rx_buf, if spi_message.is_dma_mapped
+ * @len: size of rx and tx buffers (in bytes)
+ * @cs_change: affects chipselect after this transfer completes
+ * @delay_usecs: microseconds to delay after this transfer before
+ * 	(optionally) changing the chipselect status, then starting
+ * 	the next transfer or completing this spi_message.
+ * @transfer_list: transfers are sequenced through spi_message.transfers
+ *
+ * SPI transfers always write the same number of bytes as they read.
+ * Protocol drivers should always provide rx_buf and/or tx_buf.
+ * In some cases, they may also want to provide DMA addresses for
+ * the data being transferred; that may reduce overhead, when the
+ * underlying driver uses dma.
+ *
+ * If the transmit buffer is null, undefined data will be shifted out
+ * while filling rx_buf.  If the receive buffer is null, the data
+ * shifted in will be discarded.  Only "len" bytes shift out (or in).
+ * It's an error to try to shift out a partial word.  (For example, by
+ * shifting out three bytes with word size of sixteen or twenty bits;
+ * the former uses two bytes per word, the latter uses four bytes.)
+ *
+ * All SPI transfers start with the relevant chipselect active.  Normally
+ * it stays selected until after the last transfer in a message.  Drivers
+ * can affect the chipselect signal using cs_change:
+ *
+ * (i) If the transfer isn't the last one in the message, this flag is
+ * used to make the chipselect briefly go inactive in the middle of the
+ * message.  Toggling chipselect in this way may be needed to terminate
+ * a chip command, letting a single spi_message perform all of group of
+ * chip transactions together.
+ *
+ * (ii) When the transfer is the last one in the message, the chip may
+ * stay selected until the next transfer.  This is purely a performance
+ * hint; the controller driver may need to select a different device
+ * for the next message.
+ *
+ * The code that submits an spi_message (and its spi_transfers)
+ * to the lower layers is responsible for managing its memory.
+ * Zero-initialize every field you don't set up explicitly, to

+ * back.  (In the future multi-message replies may be supported.)

+ * Both request and reply messages consist of a transport header and payload.
+ * The transport header contains info about the desired operation;
+ * the payload consists of zero or more type/length/value (TLV) items
+ * which specify parameters or results for the operation.
+ *
+ * For many operations, the request and reply messages have a fixed number
+ * of TLVs (usually zero or one); however, some reply messages may return 
+ * a variable number of TLVs.  A failed request is denoted by the presence
+ * of an "error string" TLV in the reply message instead of the TLV(s) the
