I'm seeing a build break on ppc64le which seems to be caused by this commit (I haven't bisected): util/s390-cpumsf.c: In function ‘trailer_timestamp’: util/s390-cpumsf.c:222:2: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing] return *((unsigned long long *) &te->timestamp[te->t]); ^ And on powerpc big endian: In file included from util/cpumap.h:10:0, from util/s390-cpumsf.c:150: util/s390-cpumsf.c: In function ‘s390_cpumsf_basic_show’: util/s390-cpumsf.c:187:10: error: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘size_t {aka unsigned int}’ [-Werror=format=] pr_err("Invalid AUX trace basic entry [%#08lx]\n", pos); ^ cheers
