to arrive here referencing the kernel_lev1map without having the RESERVED ASN -- another CPU may have caused pmap_lev1map_destroy() to be called, and that routine only invalidates the ASN for the CPU that called it. So, in the MULTIPROCESSOR case, simply assign the RESERVED ASN if we reference the kernel_lev1map rather than asserting that we already have the RESERVED ASN. Thanks to Bill Sommerfeld for helping me track down the problem. Also add a new IPI that causes a CPU to re-activate its address space if the pmap it's using changes level 1 maps (this probably won't happen very often, but it's correct to have it). This makes Alpha MP kernels boot multiuser. In fact, this commit is being made from my dual-CPU AlphaServer 1200 running an MP kernel. |
