If qemu-user these would possibly be expected failures. If qemu-system
or native they almost surely indicate bugs in the atomics.

arch/hexagon/bits is missing sem.h etc. so it's using the arch/generic
definitions, which only work for archs that are 64-bit or where the
only existing kernel interface has 64-bit time_t (i.e. riscv32). For
anything else they must be defined with the proper hi/lo time members,
and bits/ipcstat.h must define IPC_STAT as 0x102 to activate the
translations.

Could you send the whole src/REPORT file which contains not just the
FAIL lines but the specific test failures that caused them? And label
whether it's for qemu-user, qemu-system, or real metal.
