GCC 8.1 warns about possible string truncation:
arch/powerpc/kernel/nvram_64.c:1042:2: error: 'strncpy' specified
bound 12 equals destination size [-Werror=stringop-truncation]
strncpy(new_part->header.name, name, 12);
arch/powerpc/platforms/ps3/repository.c:106:2: error: 'strncpy'
output truncated before terminating nul copying 8 bytes from a
string of the same length [-Werror=stringop-truncation]
strncpy((char *)&n, text, 8);
Fix it by using memcpy(). To make that safe we need to ensure the
destination is pre-zeroed. Use kzalloc() in the nvram code and
initialise the u64 to zero in the ps3 code.
