pci_regs.h from linux does not have these
this is why we keep them in msi.c

[mst@tuck linux-2.6]$ grep PCI_MSI_ include/linux/pci_regs.h 
#define PCI_MSI_FLAGS           2       /* Various flags */
#define  PCI_MSI_FLAGS_64BIT    0x80    /* 64-bit addresses allowed */
#define  PCI_MSI_FLAGS_QSIZE    0x70    /* Message queue size configured
*/
#define  PCI_MSI_FLAGS_QMASK    0x0e    /* Maximum queue size available
*/
#define  PCI_MSI_FLAGS_ENABLE   0x01    /* MSI feature enabled */
#define  PCI_MSI_FLAGS_MASKBIT  0x100   /* 64-bit mask bits allowed */
#define PCI_MSI_RFU             3       /* Rest of capability flags */
#define PCI_MSI_ADDRESS_LO      4       /* Lower 32 bits */
#define PCI_MSI_ADDRESS_HI      8       /* Upper 32 bits (if
PCI_MSI_FLAGS_64BIT set) */
#define PCI_MSI_DATA_32         8       /* 16 bits of data for 32-bit
devices */
#define PCI_MSI_MASK_32         12      /* Mask bits register for 32-bit
devices */
#define PCI_MSI_DATA_64         12      /* 16 bits of data for 64-bit
devices */
#define PCI_MSI_MASK_64         16      /* Mask bits register for 64-bit
devices */


If you want to move them, please send them upstream we'll merge when
they are there.
