Sorry, forgot adding x86 and x86/mm maintainers


Hi,

    These commits need applied to Linux-5.15.0 (LTS) too since it has the
original regression :

   1d659236fb43 ("dma-pool: scale the default DMA coherent pool
size with memory capacity")

Maybe add "Fixes" to the other commits ?


And cc:stable, please.  "Fixes:" doesn't always mean "should be
backported


Hi.


Does this mean we need a v3 version ?
