For now the auxv HWCAP is masked off on arm64 in valgrind fedora. https://bugzilla.redhat.com/show_bug.cgi?id=1464211#c1 So you can reenable the sanity check again on fedora rawhide.
Upstream bug is https://bugs.kde.org/show_bug.cgi?id=381556 arm64: Handle feature registers access on 4.11 Linux kernel or later
A better workaround would be to mask out HWCAP_CPUID (0x800) from the HWCAP.
valgrind needs to mask out all unknown/unimplemented flags. And I thought it was 1? LD_HWCAP_MASK=1 acts as a workaround, after all.
because LD_HWCAP_MASK is the 'important hwcap bits' and now that is 0x800 by default on aarch64, if you unset that flag then the cpuid check is disabled.
