#     powerpc/xive: Ignore kmemleak false positives
#     
#     xive_native_provision_pages() allocates memory and passes the pointer to
#     OPAL so kmemleak cannot find the pointer usage in the kernel memory and
#     produces a false positive report (below) (even if the kernel did scan
#     OPAL memory, it is unable to deal with __pa() addresses anyway).
#     
#     This silences the warning.
#
