Cortex A9 MP: ARM errata 754323 implementation?

[Dirk Behme]

Hi,

looking through the ARM Cortex A9 errata list [1] I wonder why we don't 
have a workaround for

(754323) Repeated Store in the same cache line might delay the 
visibility of the Store

in the kernel? Or have I missed it?

We do have the workaround for the related erratum #754327 implemented 
[2], but that is supposed only for cores prior to r2p0.

While #754323 seems to affect all newer cores, too?

Any idea?

Best regards

Dirk
