Dear Maintainer,


HWCAP and HWCAP2 (used by getauxval) are not in sync between 32bits and 64bits
arch for the same processor.

for arm64 for instance see https://docs.kernel.org/arch/arm64/elf_hwcaps.html
they are more hardware caps than for arm32

Thus it is not possible to check under arm32 is a feature is enable.

Can we get an audit of other arch and get the 32/64bits in sync about feature
returned by the kernel ?

Thanks

Rouca
