CCing linux-kernel for more exposure.
PING. I'm waiting on a reply from anyone on the kernel side of things
to see whether they have an issue with reserving values for AT_HWCAP3
and AT_HWCAP4.
I'll note reviews from the GLIBC camp did not have an issue with the below
patch.
Thanks.

Hi Adhemerval, sorry for the delay in replying, I was a little under the

The powerpc toolchain keeps a copy of the HWCAP bit masks in our TCB for fast
access by our __builtin_cpu_supports built-in function. The TCB space for
the HWCAP entries - which are created in pairs - is an ABI extension, so
waiting to create the space for HWCAP3 and HWCAP4 until we need them is
