search for: config_hugetlb_pag

We''re setting up a sles10 sp3 domU that needs hugepage support according to Oracle. Everything appears to be installed to support it except for the kernel module. The current config shows: # CONFIG_HUGETLB_PAGE is not set If I try to reconfigure the kernel I can''t find anything in the config for huge page support under: File Systems ---> Pseudo File Systems ---> I also checked a sles11sp1 domU. Can hugepages be used? Is there a xenpae kernel that supports it? Thanks, James ___________...

Stub out the whole function and assign NULL to the .hugetlb_entry method if CONFIG_HUGETLB_PAGE is not set, as the method won't ever be called in that case.
