      "message": "tmpfs: fix shmem_swaplist races\n\nIntensive swapoff testing shows shmem_unuse spinning on an entry in\nshmem_swaplist pointing to itself: how does that come about?  Days pass...\n\nFirst guess is this: shmem_delete_inode tests list_empty without taking the\nglobal mutex (so the swapping case doesn\u0027t slow down the common case); but\nthere\u0027s an instant in shmem_unuse_inode\u0027s list_move_tail when the list entry\nmay appear empty (a rare case, because it\u0027s actually moving the head not the\nthe list member).  So there\u0027s a danger of leaving the inode on the swaplist\nwhen it\u0027s freed, then reinitialized to point to itself when reused.  Fix that\nby skipping the list_move_tail when it\u0027s a no-op, which happens to plug this.\n\nBut this same spinning then surfaces on another machine.  Ah, I\u0027d never\nsuspected it, but shmem_writepage\u0027s swaplist manipulation is unsafe: though we\nstill hold page lock, which would hold off inode deletion if the page were in\npagecache, it doesn\u0027t hold off once it\u0027s in swapcache (free_swap_and_cache\ndoesn\u0027t wait on locked pages).  Hmm: we could put the the inode on swaplist\nearlier, but then shmem_unuse_inode could never prune unswapped inodes.\n\nFix this with an igrab before dropping info-\u003elock, as in shmem_unuse_inode;\nthough I am a little uneasy about the iput which has to follow - it works, and\nI see nothing wrong with it, but it is surprising that shmem inode deletion\nmay now occur below shmem_writepage.  Revisit this fix later?\n\nAnd while we\u0027re looking at these races: the way shmem_unuse tests swapped\nwithout holding info-\u003elock looks unsafe, if we\u0027ve more than one swap area: a\nracing shmem_writepage on another page of the same inode could be putting it\nin swapcache, just as we\u0027re deciding to remove the inode from swaplist -\nthere\u0027s a danger of going on swap without being listed, so a later swapoff\nwould hang, being unable to locate the entry.  Move that test and removal down\ninto shmem_unuse_inode, once info-\u003elock is held.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

And\nexamining a map of nodes corresponding to swap entries on a numa\u003dfake system\nbears this out.  (We could later tweak swap allocation to make it even more\nlikely, but this patch is merely about removing cruft.)\n\nSo, neither adjust nor increment addr in swapin_readahead, and then\nshmem_swapin can use it too; the pseudo-vma to pass policy need only be set up\nonce per cluster, and so few fields of pvma are used, let\u0027s skip the memset -\nfrom shmem_alloc_page also.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Platforms can update their\nGPIO support to use this.  In many cases the incremental cost to access a\nnon-inlined GPIO should be less than a dozen instructions, with the memory\ncost being about a page (total) of extra data and code.  The upside is:\n\n  * Providing two features which were \"want to have (but OK to defer)\" when\n    GPIO interfaces were first discussed in November 2006:\n\n    -\tA \"struct gpio_chip\" to plug in GPIOs that aren\u0027t directly supported\n\tby SOC platforms, but come from FPGAs or other multifunction devices\n\tusing conventional device registers (like UCB-1x00 or SM501 GPIOs,\n\tand southbridges in PCs with more open specs than usual).\n\n    -\tFull support for message-based GPIO expanders, where registers are\n\taccessed through sleeping I/O calls.  Previous support for these\n\t\"cansleep\" calls was just stubs.  (One example: the widely used\n\tpcf8574 I2C chips, with 8 GPIOs each.)\n\n  * Including a non-stub implementation of the gpio_{request,free}() calls,\n    making those calls much more useful.  The diagnostic labels are also\n    recorded given DEBUG_FS, so /sys/kernel/debug/gpio can show a snapshot\n    of all GPIOs known to this infrastructure.\n\nThe driver programming interfaces introduced in 2.6.21 do not change at all;\nthis infrastructure is entirely below those covers.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nCc: Sam Ravnborg \u003csam@ravnborg.org\u003e\nCc: Jean Delvare \u003ckhali@linux-fr.org\u003e\nCc: Eric Miao \u003ceric.miao@marvell.com\u003e\nCc: Haavard Skinnemoen \u003chskinnemoen@atmel.com\u003e\nCc: Philipp Zabel \u003cphilipp.zabel@gmail.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Ben Gardner \u003cbgardner@wabtec.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "iommu sg merging: add device_dma_parameters structure\n\nIOMMUs merges scatter/gather segments without considering a low level\ndriver\u0027s restrictions. The problem is that IOMMUs can\u0027t access to the\nlimitations because they are in request_queue.\n\nThis patchset introduces a new structure, device_dma_parameters,\nincluding dma information. A pointer to device_dma_parameters is added\nto struct device. The bus specific structures (like pci_dev) includes\ndevice_dma_parameters. Low level drivers can use dma_set_max_seg_size\nto tell IOMMUs about the restrictions.\n\nWe can move more dma stuff in struct device (like dma_mask) to struct\ndevice_dma_parameters later (needs some cleanups before that).\n\nThis includes patches for all the IOMMUs that could merge sg (x86_64,\nppc, IA64, alpha, sparc64, and parisc) though only the ppc patch was\ntested. The patches for other IOMMUs are only compile tested.\n\nThis patch:\n\nAdd a new structure, device_dma_parameters, including dma information.  A\npointer to device_dma_parameters is added to struct device.\n\n- there are only max_segment_size and segment_boundary_mask there but we\u0027ll\n  move more dma stuff in struct device (like dma_mask) to struct\n  device_dma_parameters later.  segment_boundary_mask is not supported yet.\n\n- new accessors for the dma parameters are added.  So we can easily change\n  where to place struct device_dma_parameters in the future.\n\n- dma_get_max_seg_size returns 64K if dma_parms in struct device isn\u0027t set\n  up properly.  64K is the default max_segment_size in the block layer.\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nAcked-by: Jeff Garzik \u003cjeff@garzik.org\u003e\nCc: James Bottomley \u003cJames.Bottomley@steeleye.com\u003e\nAcked-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
