commit 273694cd78a2e12f44f8aacc88ec15853feb759a

    Add Arm HWCAP2_* constants from Linux 3.15 and 6.2 to <bits/hwcap.h>

    Linux 3.15 and 6.2 added HWCAP2_* values for Arm. These bits have
    already been added to dl-procinfo.{c,h} in commits 9aea0cb842f02 and
    8ebe9c0b38a9. Also add them to <bits/hwcap.h> so that they can be used
    in user code. For example, for checking bits in the value returned by
    getauxval(AT_HWCAP2).
