Some test systems were experiencing negative huge page reserve
counts and incorrect file block counts. This was traced to
/proc/sys/vm/drop_caches removing clean pages from hugetlbfs
file pagecaches. When non-hugetlbfs explicit code removes the
pages, the appropriate accounting is not performed.

Hi all,
Ltp has a POSIX teatcase about mmap, 24-2.c.

Use the devm_of_pci_get_host_bridge_resources() API in place of the PCI OF
