I still need to send a few checkpoint/restore patches. I've been wobbly about merging them because I'm wobbly about the overall prospects for success of the project. But after speaking with Pavel at the LSF conference, it sounds like they're further toward completion than I feared - apparently davem is at the "has stopped complaining" stage regarding the net changes.

| dac23b0 | Michal Hocko | 05 April 2012, 21:25:16 UTC | memcg swap: use mem_cgroup_uncharge_swap fix Although mem_cgroup_uncharge_swap has an empty placeholder for !CONFIG_CGROUP_MEM_RES_CTLR_SWAP the definition is placed in the CONFIG_SWAP ifdef block so we are missing the same definition for !CONFIG_SWAP which implies !CONFIG_CGROUP_MEM_RES_CTLR_SWAP. This has not been an issue before, because mem_cgroup_uncharge_swap was not called from !CONFIG_SWAP context. But Hugh Dickins has a cleanup patch to call __mem_cgroup_commit_charge_swapin which is defined also for !CONFIG_SWAP. Let's move both the empty definition and declaration outside of the CONFIG_SWAP block to avoid the following compilation error: mm/memcontrol.c: In function '__mem_cgroup_commit_charge_swapin': mm/memcontrol.c:2837: error: implicit declaration of function 'mem_cgroup_uncharge_swap' if CONFIG_SWAP is disabled.

| 7563ec4 | Hillf Danton | 05 April 2012, 21:25:09 UTC | hugetlbfs: remove unregister_filesystem() when initializing module It was introduced by d1d5e05ffdc1 ("hugetlbfs: return error code when initializing module") but as Al pointed out, is a bad idea. Quoted comments from Al: "Note that unregister_filesystem() in module init is *always* wrong; it's not an issue here (it's done too early to care about and realistically the box is not going anywhere - it'll panic when attempt to exec /sbin/init fails, if not earlier), but it's a damn bad example. Consider a normal fs module. Somebody loads it and in parallel with that we get a mount attempt on that fs type. It comes between register and failure exits that causes unregister; at that point we are screwed since grabbing a reference to module as done by mount is enough to prevent exit, but not to prevent the failure of init. As the result, module will get freed when init fails, mounted fs of that type be damned." So remove it.

| b82c328 | Anton Vorontsov | 05 April 2012, 21:25:05 UTC | sysrq: use SEND_SIG_FORCED instead of force_sig() Change send_sig_all() to use do_send_sig_info(SEND_SIG_FORCED) instead of force_sig(SIGKILL). With the recent changes we do not need force_ to kill the CLONE_NEWPID tasks. And this is more correct. force_sig() can race with the exiting thread, while do_send_sig_info(group => true) kill the whole process. Some more notes from Oleg Nesterov: > Just one note. This change makes no difference for sysrq_handle_kill(). > But it obviously changes the behaviour sysrq_handle_term(). I think > this is fine, if you want to really kill the task which blocks/ignores > SIGTERM you can use sysrq_handle_kill(). > > Even ignoring the reasons why force_sig() is simply wrong here, > force_sig(SIGTERM) looks strange. The task won't be killed if it has > a handler, but SIG_IGN can't help. However if it has the handler > but blocks SIGTERM temporary (this is very common) it will be killed. Also, > force_sig() can't kill the process if the main thread has already > exited. IOW, it is trivial to create the process which can't be > killed by sysrq. So, this patch fixes the issue.

| 58bca4a | Linus Torvalds | 05 April 2012, 00:13:43 UTC | Merge branch 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping Pull DMA mapping branch from Marek Szyprowski: "Short summary for the whole series: A few limitations have been identified in the current dma-mapping design and its implementations for various architectures. There exist more than one function for allocating and freeing the buffers: currently these 3 are used dma_{alloc, free}_coherent, dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent. For most of the systems these calls are almost equivalent and can be interchanged. For others, especially the truly non-coherent ones (like ARM), the difference can be easily noticed in overall driver performance. Sadly not all architectures provide implementations for all of them, so the drivers might need to be adapted and cannot be easily shared between different architectures. The provided patches unify all these functions and hide the differences under the already existing dma attributes concept. The thread with more references is available here: http://www.spinics.net/lists/linux-sh/msg09777.html These patches are also a prerequisite for unifying DMA-mapping implementation on ARM architecture with the common one provided by dma_map_ops structure and extending it with IOMMU support. More information is available in the following thread: http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819 More works on dma-mapping framework are planned, especially in the area of buffer sharing and managing the shared mappings (together with the recently introduced dma_buf interface: commit d15bd7ee445d "dma-buf: Introduce dma buffer sharing mechanism"). The patches in the current set introduce a new alloc/free methods (with support for memory attributes) in dma_map_ops structure, which will later replace dma_alloc_coherent and dma_alloc_writecombine functions." People finally started piping up with support for merging this, so I'm merging it as the last of the pending stuff from the merge window.

This is really too late, but it's a long-overdue cleanup of the costly wrapper functions for the security layer. The "struct common_audit_data" is used all over in critical paths, allocated and initialized on the stack. And used to be much too large, causing not only unnecessarily big stack frames but the clearing of the (mostly useless) data was also very visible in profiles. As a particular example, in one microbenchmark for just doing "stat()" over files a lot, selinux_inode_permission() used 7% of the CPU time. That's despite the fact that it doesn't actually *do* anything: it is just a helper wrapper function in the selinux security layer. This patch-series shrinks "struct common_audit_data" sufficiently that code generation for these kinds of wrapper functions is improved noticeably, and we spend much less time just initializing data that we will never use. The functions still get called all the time, and it still shows up at 3.5+% in my microbenchmark, but it's quite a bit lower down the list, and much less noticeable. * Emailed patches from Eric Paris <eparis@redhat.com>: lsm_audit: don't specify the audit pre/post callbacks in 'struct common_audit_data' SELinux: do not allocate stack space for AVC data unless needed SELinux: remove avd from slow_avc_audit() SELinux: remove avd from selinux_audit_data LSM: shrink the common_audit_data data union LSM: shrink sizeof LSM specific portion of common_audit_data | 04 April 2012, 17:11:24 UTC |

To do this I'm going to move anything larger than 2 void * ptrs to it's own structure and require it to be declared separately on the calling stack. Thus hot paths which don't need more than a couple pointer don't have to declare space to hold large unneeded structures.

In most cases we read a whole page, but in some cases with bad blocks or odd sizes devices we might read fewer than that.

| d06221c | Benjamin Herrenschmidt | 02 April 2012, 03:38:19 UTC | nouveau/bios: Fix tracking of BIOS image data The code tries various methods for retreiving the BIOS data. However it doesn't clear the bios->data pointer between the iterations. In some cases, the shadow() method will fail and not update bios->data at all, which will cause us to "score" the old data and incorrectly attribute that score to the new method. This can cause double frees later when disposing of the unused data. Additionally, we were not freeing the data for methods that fail the score test (we only freed when a "best" is superseeded, not when the new method has a lower score than the exising "best"). Fix that as well.
