Hi Venkat,
CC Kees Cook for advice. This is a result of the tests added in commit
bbeb38b8487a ("string.h: Validate memtostr*()/strtomem*() arguments more
carefully")
from the kspp tree.
I note that the comment about memtostr() says "Copy a possibly
non-NUL-term string".
Can you tell more about your config and your environment ?
I just tested with ppc64_defconfig and ppc64le_defconfig, with gcc 12.4,
gcc 13.2 and gcc 14.2 and didn't get that build error.

FWIW, I see the same build failures related to __must_be_noncstr()
when building natively on x86 and on arm64. In both cases, it's an
Ubuntu 20.04 installation with gcc 9.4.0 and binutils 2.34.
Looks like I get that problem only with GCC 8.5 and GCC 9.5.
I don't get it with gcc 10.3 nor 11.3 nor 12.4 nor 13.2 nor 14.2
I don't get it either with gcc 5.5 or 7.5
Christophe
