Konstantin Belousov bced332adf Invalidate cache for the PDPTE page when using PAE paging but PAT is ... not supported. According to SDM rev. 69 vol. 3, for PDPTE registers loads: - when PAT is not supported, access to the PDPTE page is performed as UC, see 4.9.1; - when PAT is supported, the access is WB, see 4.9.2. So potentially CPU might load stale memory as PDPTEs if both PAT and self-snoop are not implemented. To be safe, add total local cache flush to pmap_cold() before initial load of cr3, and flush PDPTE page in pmap_pinit(), if PAT is not implemented.
