lib/test_overflow.c: avoid tainting the kernel and fix wrap size
[ Upstream commit 8e060c21ae2c265a2b596e9e7f9f97ec274151a4 ]
This adds __GFP_NOWARN to the kmalloc()-portions of the overflow test to
avoid tainting the kernel. Additionally fixes up the math on wrap size
to be architecture and page size agnostic.
