[ Upstream commit f0993c839e95dd6c7f054a1015e693c87e33e4fb ]
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.
