[linux-yocto] L3 cache way-locking memory zone

[Marek Bykowski]

Hi Community,

I'd like to query if you would see a benefit from adding in an extra
memory zone to L3 cache lock region/s?

This is useful if a platform/system features the L3 cache (LLC) that can
be configured to way-locking (eg. such as it could in CCN-512). The
benefits arising from it are as, the ones resulting in from cache
locking, faster memory access.

We have such an implementation for arm64, kernel 4.9 and higher, is in
a bit dirty state but if you are interested I could work towards
cleaning and then share.

Thanks,
Marek
