What's failing is preadv2/readv over PROT_NONE mapping:

[pid  2424] mmap(NULL, 1, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, 0, 0) = 0x3ff7f8b0000
[pid  2424] preadv2(3, [{iov_base=0x3ff7f8b0000, iov_len=64}], 1, 0, 0) = 16

Test expects EFAULT.

It seems specific to arm64/linux.git as I do not see it fail on
Linus' master (v5.4-rc5-34-g23fdb198ae81).

Regards,
Jan
