yum and wildcard problems
I am having trouble using wildcards ("*") with yum in Centos 5. Listing or installing packages using them just immeidately fails with a "No match" error, and I'm not sure why. Here is an example. Any comments? I'd love to fix this. [root at granta ~]# ps -e | grep yum 2706 ? 00:00:22 yum-updatesd [root at granta ~]# yum list | grep kern kernel.x86_64 2.6.18-8.1.1...

[PATCH v4 6/6] mm/migrate: remove range invalidation in migrate_vma_pages()
...igrate_vma_setup() > step and a pte_none() or zero page can't be modified so the only invalidation needed > is the CPU TLB(s) for clearing the special zero page PTE entry. No, the secondary MMU was invalidated but the invalidation start/end range was exited. That means a secondary MMU is immeidately able to reload the zero page into its MMU cache. When this code replaces the PTE that has a zero page it also has to invalidate again so that secondary MMU's are guaranteed to pick up the new PTE value. So, I still don't understand how this is safe? Jason
