+/* Sun4v hypervisor interfaces and defines.
+ *
+ * Hypervisor calls are made via traps to software traps number 0x80
+ * and above.  Registers %o0 to %o5 serve as argument, status, and
+ * return value registers.
+ *
+ * There are two kinds of these traps.  First there are the normal
+ * "fast traps" which use software trap 0x80 and encode the function
+ * to invoke by number in register %o5.  Argument and return value
+ * handling is as follows:
+ *
+ * -----------------------------------------------
+ * |  %o5  | function number |     undefined     |
+ * |  %o0  |   argument 0    |   return status   |
+ * |  %o1  |   argument 1    |   return value 1  |
+ * |  %o2  |   argument 2    |   return value 2  |
+ * |  %o3  |   argument 3    |   return value 3  |
+ * |  %o4  |   argument 4    |   return value 4  |
+ * -----------------------------------------------
+ *
+ * The second type are "hyper-fast traps" which encode the function
+ * number in the software trap number itself.  So these use trap
+ * numbers > 0x80.  The register usage for hyper-fast traps is as
+ * follows:
+ *
+ * -----------------------------------------------
+ * |  %o0  |   argument 0    |   return status   |
+ * |  %o1  |   argument 1    |   return value 1  |
+ * |  %o2  |   argument 2    |   return value 2  |
+ * |  %o3  |   argument 3    |   return value 3  |
+ * |  %o4  |   argument 4    |   return value 4  |
+ * -----------------------------------------------
+ *
+ * Registers providing explicit arguments to the hypervisor calls
+ * are volatile across the call.  Upon return their values are
+ * undefined unless explicitly specified as containing a particular
+ * return value by the specific call.  The return status is always
+ * returned in register %o0, zero indicates a successful execution of
+ * the hypervisor call and other values indicate an error status as
+ * defined below.  So, for example, if a hyper-fast trap takes
+ * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
+ * the call and %o3, %o4, and %o5 would be preserved.
+ *
+ * If the hypervisor trap is invalid, or the fast trap function number
+ * is invalid, HV_EBADTRAP will be returned in %o0.  Also, all 64-bits
+ * of the argument and return values are significant.

+/* PCI IO services.
+ *
+ * See the terminology descriptions in the device interrupt services
+ * section above as those apply here too.  Here are terminology
+ * definitions specific to these PCI IO services:
+ *
+ *      tsbnum          TSB number.  Indentifies which io-tsb is used.
+ *                      For this version of the specification, tsbnum
+ *                      must be zero.
+ *
+ *      tsbindex        TSB index.  Identifies which entry in the TSB
+ *                      is used.  The first entry is zero.
+ *
+ *      tsbid           A 64-bit aligned data structure which contains
+ *                      a tsbnum and a tsbindex.  Bits 63:32 contain the
+ *                      tsbnum and bits 31:00 contain the tsbindex.
+ *
+ *                      Use the HV_PCI_TSBID() macro to construct such
+ *                      values.
+ *
+ *      io_attributes   IO attributes for IOMMU mappings.  One of more
+ *                      of the attritbute bits are stores in a 64-bit
+ *                      value.  The values are defined below.
+ *
+ *      r_addr          64-bit real address
+ *
+ *      pci_device      PCI device address.  A PCI device address identifies
+ *                      a specific device on a specific PCI bus segment.
+ *                      A PCI device address ia a 32-bit unsigned integer
+ *                      with the following format:
+ *
+ *                              00000000.bbbbbbbb.dddddfff.00000000
+ *
+ *                      Use the HV_PCI_DEVICE_BUILD() macro to construct
+ *                      such values.
+ *
+ *      pci_config_offset
+ *                      PCI configureation space offset.  For conventional
+ *                      PCI a value between 0 and 255.  For extended
+ *                      configuration space, a value between 0 and 4095.
+ *
+ *                      Note: For PCI configuration space accesses, the offset
+ *                            must be aligned to the access size.
+ *
+ *      error_flag      A return value which specifies if the action succeeded
+ *                      or failed.  0 means no error, non-0 means some error
+ *                      occurred while performing the service.
+ *
+ *      io_sync_direction
+ *                      Direction definition for pci_dma_sync(), defined
+ *                      below in HV_PCI_SYNC_*.
+ *
+ *      io_page_list    A list of io_page_addresses, an io_page_address is
+ *                      a real address.
+ *
+ *      io_page_list_p  A pointer to an io_page_list.
+ *
+ *      "size based byte swap" - Some functions do size based byte swapping
+ *                               which allows sw to access pointers and
+ *                               counters in native form when the processor
+ *                               operates in a different endianness than the
+ *                               IO bus.  Size-based byte swapping converts a
+ *                               multi-byte field between big-endian and
+ *                               little-endian format.

+ * comparison TAG based upon the virtual address and context which
