| |
In commit 7a0fc404ae663776e96db43879a0fa24fec1fa3a you disable use of PSE, but I wonder how this can take any effect on 64-bit CPUs, as they use large pages during early boot already. Those pages, when use of PSE gets disabled, will get broken up into 4k pages in phys_pmd_init(), thus actually increasing the chances that you hit the erratum.
What am I missing?
