2011-05-22x86, apic: Clean up bigsmp apic selection codeSuresh Siddha
Make generic_bigsmp_probe() return struct apic *. This will avoid exporting apic_bigsmp, which will be consistent with others.

2011-05-22x86, apic: Introduce .apicdrivers section to find the list of apic driversSuresh Siddha
This will pave the way for each apic driver to be self-contained and eliminate the need for apic_probe[]. Order in which apic drivers are listed in the .apicdrivers section is important, as this determines the apic probe order. And this is enforced by the ordering of apic driver files in the Makefile and the macros apic_driver()/apic_drivers().

2011-05-21PCI: update bridge resources to get more big ranges when allocating space ↵Yinghai Lu
(again) With Ram's fixes, this should be safe to do again. So let's give it another try. BIOS separates IO ranges between several IOHs, and on some slots, BIOS assigns resources to a bridge, but stops assigning resources to the device under that bridge, because the device needs a big resource. So: 1. allocate resources and record the failed device resources 2. clear the BIOS assigned resources of the parent bridge of failing device 3. go back and call pci assign unassigned 4. if it still fails, go up the tree, clear more bridges. and try again Now Ram's allocate requested resource already got into mainline. could put this one again.

For KVM device assignment, we'd like to save off the state of a device prior to passing it to the guest and restore it later. We also want to allow pci_reset_funciton() to be called while the device is owned by the guest. This however overwrites and invalidates the struct pci_dev buffers, so we can't just manually call save and restore.

2011-05-21GFS2: Wipe directory hash table metadata when deallocating a directorySteven Whitehouse
The deallocation code for directories in GFS2 is largely divided into two parts. The first part deallocates any directory leaf blocks and marks the directory as being a regular file when that is complete. The second stage was identical to deallocating regular files. Regular files have their data blocks in a different address space to directories, and thus what would have been normal data blocks in a regular file (the hash table in a GFS2 directory) were deallocated correctly. However, a reference to these blocks was left in the journal (assuming of course that some previous activity had resulted in those blocks being in the journal or ail list). This patch uses the i_depth as a test of whether the inode is an exhash directory (we cannot test the inode type as that has already been changed to a regular file at this stage in deallocation) The original issue was reported by Chris Hertel as an issue he encountered running bonnie++ Reported-by: Christopher R.

2011-05-21slub: Deal with hyperthetical case of PAGE_SIZE > 2MChristoph Lameter
kmalloc_index() currently returns -1 if the PAGE_SIZE is larger than 2M which seems to cause some concern since the callers do not check for -1. Insert a BUG() and add a comment to the -1 explaining that the code cannot be reached. Signed-off-by: Christoph Lameter <cl@linux.com> Signed-off-by: Pekka Enberg <penberg@kernel.org>
2011-05-21slub: Remove node check in slab_freeChristoph Lameter
We can set the page pointing in the percpu structure to NULL to have the same effect as setting c->node to NUMA_NO_NODE. Gets rid of one check in slab_free() that was only used for forcing the slab_free to the slowpath for debugging. We still need to set c->node to NUMA_NO_NODE to force the slab_alloc() fastpath to the slowpath in case of debugging.

2011-05-21VFS: move BUG_ON test for symlink nd->depth after current->link_count testErez Zadok
This solves a serious VFS-level bug in nested_symlink (which was rewritten from do_follow_link), and follows the order of depth tests that existed before. The bug triggers a BUG_ON in fs/namei.c:1381, when running racer with symlink and rename ops.
