| * | fix off-by-one mistakes in vm_alloc() | Jan Beulich | 2013-08-05 | 1 | -10/+18 |
| | | | | | | | | | | | | Also add another pair of assertions to catch eventual further cases of incorrect accounting, and remove the temporary debuggin messages again which commit 68caac7f ("x86: don't use destroy_xen_mappings() for vunmap()") added.

| * | x86: don't use destroy_xen_mappings() for vunmap() | Jan Beulich | 2013-07-17 | 1 | -0/+6 |
| | | | | | | | | | | | | | | | | | | | Its attempt to tear down intermediate page table levels may race with map_pages_to_xen() establishing them, and now that map_domain_page_global() is backed by vmap() this teardown is also wasteful (as it's very likely to need the same address space populated again within foreseeable time). As the race between vmap() and vunmap(), according to the latest stage tester logs, doesn't appear to be the only one still left, the patch also adds logging for vmap() and vunmap() uses (there shouldn't be too many of them, so logs shouldn't get flooded). These are supposed to get removed (and are made stand out clearly) as soon as we're certain that there's no issue left.
