The first is inline data, which allows small files or directories to be stored in the in-inode extended attribute area.

2012-12-16ARM: OMAP: Fix drivers to depend on omap for internal devicesTony Lindgren
These devices are not available on other architectures, so let's limit them to omap. If the driver subsystem maintainers want to build test system wide changes without building for each target, it's easy to carry a test patch that just strips out the depends entries from Kconfig files.

2012-12-16Merge tag 'balancenuma-v11' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma Pull Automatic NUMA Balancing bare-bones from Mel Gorman: "There are three implementations for NUMA balancing, this tree (balancenuma), numacore which has been developed in tip/master and autonuma which is in aa.git. In almost all respects balancenuma is the dumbest of the three because its main impact is on the VM side with no attempt to be smart about scheduling. In the interest of getting the ball rolling, it would be desirable to see this much merged for 3.8 with the view to building scheduler smarts on top and adapting the VM where required for 3.9. The most recent set of comparisons available from different people are mel: https://lkml.org/lkml/2012/12/9/108 mingo: https://lkml.org/lkml/2012/12/7/331 tglx: https://lkml.org/lkml/2012/12/10/437 srikar: https://lkml.org/lkml/2012/12/10/397 The results are a mixed bag. In my own tests, balancenuma does reasonably well. It's dumb as rocks and does not regress against mainline. On the other hand, Ingo's tests shows that balancenuma is incapable of converging for this workloads driven by perf which is bad but is potentially explained by the lack of scheduler smarts. Thomas' results show balancenuma improves on mainline but falls far short of numacore or autonuma. Srikar's results indicate we all suffer on a large machine with imbalanced node sizes. My own testing showed that recent numacore results have improved dramatically, particularly in the last week but not universally. We've butted heads heavily on system CPU usage and high levels of migration even when it shows that overall performance is better. There are also cases where it regresses. Of interest is that for specjbb in some configurations it will regress for lower numbers of warehouses and show gains for higher numbers which is not reported by the tool by default and sometimes missed in treports. Recently I reported for numacore that the JVM was crashing with NullPointerExceptions but currently it's unclear what the source of this problem is. Initially I thought it was in how numacore batch handles PTEs but I'm no longer think this is the case. It's possible numacore is just able to trigger it due to higher rates of migration. These reports were quite late in the cycle so I/we would like to start with this tree as it contains much of the code we can agree on and has not changed significantly over the last 2-3 weeks." * tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma: (50 commits) mm/rmap, migration: Make rmap_walk_anon() and try_to_unmap_anon() more scalable mm/rmap: Convert the struct anon_vma::mutex to an rwsem mm: migrate: Account a transhuge page properly when rate limiting mm: numa: Account for failed allocations and isolations as migration failures mm: numa: Add THP migration for the NUMA working set scanning fault case build fix mm: numa: Add THP migration for the NUMA working set scanning fault case. mm: sched: numa: Delay PTE scanning until a task is scheduled on a new node mm: sched: numa: Control enabling and disabling of NUMA balancing if !SCHED_DEBUG mm: sched: numa: Control enabling and disabling of NUMA balancing mm: sched: Adapt the scanning rate if a NUMA hinting fault does not migrate mm: numa: Use a two-stage filter to restrict pages being migrated for unlikely task<->node relationships mm: numa: migrate: Set last_nid on newly allocated page mm: numa: split_huge_page: Transfer last_nid on tail page mm: numa: Introduce last_nid to the page frame sched: numa: Slowly increase the scanning period as NUMA faults are handled mm: numa: Rate limit setting of pte_numa if node is saturated mm: numa: Rate limit the amount of memory that is migrated between nodes mm: numa: Structures for Migrate On Fault per NUMA migration rate limiting mm: numa: Migrate pages handled during a pmd_numa hinting fault mm: numa: Migrate on reference policy ...

The .notes, being read-only data by nature, were placed between read-write .data and .bss. This was harmful in case of the XIP kernel, as being placed in the RAM range, most likely far from the ROM address, was inflating the XIP images. Moving the .notes at the end of the read-only section (consisting of .text, .rodata and unwind info) fixes the problem.

2012-12-15sctp: Change defaults on cookie hmac selectionNeil Horman
Recently I posted commit 3c68198e75 which made selection of the cookie hmac algorithm selectable. This is all well and good, but Linus noted that it changes the default config: http://marc.info/?l=linux-netdev&m=135536629004808&w=2 I've modified the sctp Kconfig file to reflect the recommended way of making this choice, using the thermal driver example specified, and brought the defaults back into line with the way they were prior to my origional patch Also, on Linus' suggestion, re-adding ability to select default 'none' hmac algorithm, so we don't needlessly bloat the kernel by forcing a non-none default. This also led me to note that we won't honor the default none condition properly because of how sctp_net_init is encoded. Fix that up as well. Tested by myself (allbeit fairly quickly). All configuration combinations seems to work soundly.

2012-12-15NFS: Don't use SetPageError in the NFS writeback codeTrond Myklebust
The writeback code is already capable of passing errors back to user space by means of the open_context->error. In the case of ENOSPC, Neil Brown is reporting seeing 2 errors being returned. Neil writes: "e.g. if /mnt2/ if an nfs mounted filesystem that has no space then strace dd if=/dev/zero conv=fsync >> /mnt2/afile count=1 reported Input/output error and the relevant parts of the strace output are: write(1, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 512) = 512 fsync(1) = -1 EIO (Input/output error) close(1) = -1 ENOSPC (No space left on device)" Neil then shows that the duplication of error messages appears to be due to the use of the PageError() mechanism, which causes filemap_fdatawait_range to return the extra EIO. The regression was introduced by commit 7b281ee026552f10862b617a2a51acf49c829554 (NFS: fsync() must exit with an error if page writeback failed). Fix this by removing the call to SetPageError(), and just relying on open_context->error reporting the ENOSPC back to fsync().

2012-12-15Revert "x86, mm: Include the entire kernel memory map in trampoline_pgd"Linus Torvalds
This reverts commit 53b87cf088e2ea68d7c59619d0214cc15bb76133. It causes odd bootup problems on x86-64. Markus Trippelsdorf gets a repeatable oops, and I see a non-repeatable oops (or constant stream of messages that scroll off too quickly to read) that seems to go away with this commit reverted. So we don't know exactly what is wrong with the commit, but it's definitely problematic, and worth reverting sooner rather than later.
