f4adb109de HV: store a pointer to pdev instead to save memory.
As we store the physical pci device info in a global pdev array, the vdev struct can
store a pointer to pdev instead.

f082176df0 HV: init ptdev bar during runtime for partition mode
Current pt devices bar info for partion mode is hardcoded in
vm_description.c, now we remove the hardcoded info and parse the bar
info during pt devices init.

970821462b hv: Use Interrupt Remapping format for programming interrupt sources
When a corresponding IOMMU is found for the device, this patch adds
support to program Interrupt Remapping hardware RTEs and the original
interrupt sources (MSI or IOAPIC) with IR format.

12211fb67b hv: fix MISRA-C violations in dm/vpci
120D: Pointer param should be declared pointer to const.
  Add 'const' qualifier to function parameters whenever it's possible:
    alloc_pci_vdev()
    enumerate_pci_dev()
    pci_scan_bus()
    pci_enumeration_cb()
    partition_mode_vpci_init()
    partition_mode_vpci_deinit()
    sharing_mode_vpci_init()
    sharing_mode_vpci_deinit()
    vpci_cleanup()

45D: Pointer not checked for null before use.
  Check pointer vm in vpci_reset_ptdev_intr_info() before using it.

Reduce the count of the "return entries".
Fix the violations which is comply with the cases list below:
1.Function has 2 return entries.
2.The first return entry is used to return the error code of
checking variable whether is valid.

Fix the violations in "if else" format.
V1->V2:
    make the return value match to int32_t

366042cac2 hv: fix integer violations
- Fix the integer violations related to the following rules:
  1. The operands to shift operations (<<, >>) shall be unsigned
     integers.
  2. The operands to bit operations (&, |, ~) shall be unsigned
     integers.

- Replace 12U with CPU_PAGE_SHIFT when it is address shift case.

v1 -> v2:
 * use existed MACRO to get bus/slot/func values
 * update PCI_SLOT MACRO to make it more straightforward
 * remove the incorrect replacement of 12U with CPU_PAGE_SHIFT

dcebdb8e98 hv: implement msi.c to handle MSI remapping for vm0
Emulate MSI Capability structure for vm0 in sharing mode:

- it intercepts the IO requests for MSI Capability structure, emulates
  the Message Control word, and bypasses all other I/O requests to the
  physical device.

- criteria to trigger MSI remapping: MSI Enable bit is being changed,
  Message Data/Addr is being changed when MSI Enable is set.
