Subject: MdePkg/PciSegmentLibSegmentInfo: Change parameters type
X-Git-Tag: edk2-stable201905~450
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=2ac896a67b8eb0c42a3c39dc7e4b39eac4ba8733;p=mirror_edk2.git

MdePkg/PciSegmentLibSegmentInfo: Change parameters type

The current structure can lead to dependency on VC++ compiler support
functions when build for "IA32" with "/Od" switch, such as _aullshr().
So change the type of parameters in structure
PCI_SEGMENT_LIB_ADDRESS_STRUCTURE from UINT64 to UINT32.
