The Feodra project, while\ntrying to replace suid apps with file capabilities, realized that tmpfs,\nwhich is used on the build systems, does not support file capabilities and\nthus cannot be used to build packages which use file capabilities. Xattrs\nare also needed for overlayfs.\n\nThe xattr interface is a bit odd. If a filesystem does not implement any\n{get,set,list}xattr functions the VFS will call into some random LSM hooks\nand the running LSM can then implement some method for handling xattrs.\nSELinux for example provides a method to support security.selinux but no\nother security.* xattrs.\n\nAs it stands today when one enables CONFIG_TMPFS_POSIX_ACL tmpfs will have\nxattr handler routines specifically to handle acls. Because of this tmpfs\nwould loose the VFS/LSM helpers to support the running LSM. To make up\nfor that tmpfs had stub functions that did nothing but call into the LSM\nhooks which implement the helpers.\n\nThis new patch does not use the LSM fallback functions and instead just\nimplements a native get/set/list xattr feature for the full security.* and\ntrusted.* namespace like a normal filesystem.

For example, when adding new\ncallers of the *_mm_counter() functions a developer needs to ensure that\nthose paths are always executed with page_table_lock held, in case we\u0027re\nusing the non-atomic implementation of mm counters.\n\nHugh Dickins introduced the atomic mm counters in commit f412ac08c986\n(\"[PATCH] mm: fix rss and mmlist locking\"). When asked why he left the\nnon-atomic counters around he said,\n\n | The only reason was to avoid adding costly atomic operations into a\n | configuration that had no need for them there: the page_table_lock\n | sufficed.\n |\n | Certainly it would be simpler just to delete the non-atomic variant.\n |\n | And I think it\u0027s fair to say that any configuration on which we\u0027re\n | measuring performance to that degree (rather than \"does it boot fast?\"\n | type measurements), would already be going the split ptlocks route.\n\nRemoving the non-atomic counters eases the maintenance burden because\ndevelopers no longer have to mindful of the two implementations when using\n*_mm_counter().\n\nNote that all architectures provide a means of atomically updating\natomic_long_t variables, even if they have to revert to the generic\nspinlock implementation because they don\u0027t support 64-bit atomic\ninstructions (see lib/atomic64.c).\n\nSigned-off-by: Matt Fleming \u003cmatt.fleming@linux.intel.com\u003e\nAcked-by: Dave Hansen \u003cdave@linux.vnet.ibm.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ba93fa81b5f2bf0076407a3a777fff122ce16220", "tree": "c859d60816b3815679b45d7e492fbbe03e7e2b19", "parents": [ "e3c40f379a144f35e53864a2cd970e238071afd7" ], "author": { "name": "Daniel Kiper", "email": "dkiper@net-space.pl", "time": "Tue May 24 17:12:34 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:39:29 2011 -0700" }, "message": "mm: do not define PFN_SECTION_SHIFT if !CONFIG_SPARSEMEM\n\nDo not define PFN_SECTION_SHIFT if !CONFIG_SPARSEMEM.\n\nSigned-off-by: Daniel Kiper \u003cdkiper@net-space.pl\u003e\nAcked-by: Dave Hansen \u003cdave@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e3c40f379a144f35e53864a2cd970e238071afd7", "tree": "6636214fe729d2ee08780a44ab92bed66c0074db", "parents": [ "bf4e8902ee5080f5d2c810b639e7e778c8082b52" ], "author": { "name": "Daniel Kiper", "email": "dkiper@net-space.pl", "time": "Tue May 24 17:12:33 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:39:29 2011 -0700" }, "message": "mm: pfn_to_section_nr()/section_nr_to_pfn() is valid only in CONFIG_SPARSEMEM context\n\npfn_to_section_nr()/section_nr_to_pfn() is valid only in CONFIG_SPARSEMEM\ncontext.

purpose of these patches was to allow preemptible mmu_gather,\nbut even without that I think these patches provide an improvement to the\nstatus quo.\n\nThe first 9 patches rework the mmu_gather infrastructure. For review\npurpose I\u0027ve split them into generic and per-arch patches with the last of\nthose a generic cleanup.\n\nThe next patch provides generic RCU page-table freeing, and the followup\nis a patch converting s390 to use this. I\u0027ve also got 4 patches from\nDaveM lined up (not included in this series) that uses this to implement\ngup_fast() for sparc64.\n\nThen there is one patch that extends the generic mmu_gather batching.\n\nAfter that follow the mm preemptibility patches, these make part of the mm\na lot more preemptible. It converts i_mmap_lock and anon_vma-\u003elock to\nmutexes which together with the mmu_gather rework makes mmu_gather\npreemptible as well.\n\nMaking i_mmap_lock a mutex also enables a clean-up of the truncate code.\n\nThis also allows for preemptible mmu_notifiers, something that XPMEM I\nthink wants.\n\nFurthermore, it removes the new and universially detested unmap_mutex.\n\nThis patch:\n\nRemove the first obstacle towards a fully preemptible mmu_gather.\n\nThe current scheme assumes mmu_gather is always done with preemption\ndisabled and uses per-cpu storage for the page batches. Change this to\ntry and allocate a page for batching and in case of failure, use a small\non-stack array to make some progress.\n\nPreemptible mmu_gather is desired in general and usable once i_mmap_lock\nbecomes a mutex. Doing it before the mutex conversion saves us from\nhaving to rework the code by moving the mmu_gather bits inside the\npte_lock.\n\nAlso avoid flushing the tlb batches from under the pte lock, this is\nuseful even without the i_mmap_lock conversion as it significantly reduces\npte lock hold times.\n\n[akpm@linux-foundation.org: fix comment tpyo]\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Richard Weinberger \u003crichard@nod.at\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nReviewed-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: Hugh Dickins \u003chughd@google.com\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nCc: Namhyung Kim \u003cnamhyung@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d05f3169c0fbca16132ec7c2be71685c6de638b5", "tree": "37d82004869fa4e530617883f12cab7538dbd4a6", "parents": [ "248ac0e1943ad1796393d281b096184719eb3f97" ], "author": { "name": "Michal Hocko", "email": "mhocko@suse.cz", "time": "Tue May 24 17:11:44 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:39:12 2011 -0700" }, "message": "mm: make expand_downwards() symmetrical with expand_upwards()\n\nCurrently we have expand_upwards exported while expand_downwards is\naccessible only via expand_stack or expand_stack_downwards.\n\ncheck_stack_guard_page is a nice example of the asymmetry.

We also set High Speed Enable in case one of the\nUHS-I modes is selected. We take care to reset SD clock before setting\nUHS mode in the Host Control2 register, and then re-enable it as per\nthe Host Controller spec v3.00. We then set the clock frequency for\nthe UHS-I mode selected.\n\nTested by Zhangfei Gao with a Toshiba uhs card and general hs card,\non mmp2 in SDMA mode.\n\nSigned-off-by: Arindam Nath \u003carindam.nath@amd.com\u003e\nReviewed-by: Philip Rakity \u003cprakity@marvell.com\u003e\nTested-by: Philip Rakity \u003cprakity@marvell.com\u003e\nAcked-by: Zhangfei Gao \u003czhangfei.gao@marvell.com\u003e\nSigned-off-by: Chris Ball \u003ccjb@laptop.org\u003e\n" }, { "commit": "d6d50a15a2897d4133d536dd4343b5cf21163db3", "tree": "b56723c1b3e74ae2ae9e9d7fb39e916cdfa74958", "parents": [ "013909c4ffd16ded4895528b856fd8782df04dc6" ], "author": { "name": "Arindam Nath", "email": "arindam.nath@amd.com", "time": "Thu May 05 12:18:59 2011 +0530" }, "committer": { "name": "Chris Ball", "email": "cjb@laptop.org", "time": "Tue May 24 23:53:24 2011 -0400" }, "message": "mmc: sd: add support for driver type selection\n\nThis patch adds support for setting driver strength during UHS-I\ninitialization procedure.

Apart\nfrom other things, this new register indicates whether the Host\nController supports SDR50, SDR104, and DDR50 UHS-I modes. The spec\ndoesn\u0027t mention about explicit support for SDR12 and SDR25 UHS-I\nmodes, so the Host Controller v3.00 should support them by default.\nAlso if the controller supports SDR104 mode, it will also support\nSDR50 mode as well. So depending on the host support, we set the\ncorresponding MMC_CAP_* flags. One more new register. Host Control2\nis added in v3.00, which is used during Signal Voltage Switch\nprocedure described below.\n\nSince as per v3.00 spec, UHS-I supported hosts should set S18R\nto 1, we set S18R (bit 24) of OCR before sending ACMD41. We also\nneed to set XPC (bit 28) of OCR in case the host can supply \u003e150mA.\nThis support is indicated by the Maximum Current Capabilities\nregister of the Host Controller.\n\nIf the response of ACMD41 has both CCS and S18A set, we start the\nsignal voltage switch procedure, which if successfull, will switch\nthe card from 3.3V signalling to 1.8V signalling. Signal voltage\nswitch procedure adds support for a new command CMD11 in the\nPhysical Layer Spec v3.01. As part of this procedure, we need to\nset 1.8V Signalling Enable (bit 3) of Host Control2 register, which\nif remains set after 5ms, means the switch to 1.8V signalling is\nsuccessfull. Otherwise, we clear bit 24 of OCR and retry the\ninitialization sequence. When we remove the card, and insert the\nsame or another card, we need to make sure that we start with 3.3V\nsignalling voltage. So we call mmc_set_signal_voltage() with\nMMC_SIGNAL_VOLTAGE_330 set so that we are back to 3.3V signalling\nvoltage before we actually start initializing the card.\n\nTested by Zhangfei Gao with a Toshiba uhs card and general hs card,\non mmp2 in SDMA mode.\n\nSigned-off-by: Arindam Nath \u003carindam.nath@amd.com\u003e\nReviewed-by: Philip Rakity \u003cprakity@marvell.com\u003e\nTested-by: Philip Rakity \u003cprakity@marvell.com\u003e\nAcked-by: Zhangfei Gao \u003czhangfei.gao@marvell.com\u003e\nSigned-off-by: Chris Ball \u003ccjb@laptop.org\u003e\n" }, { "commit": "cb87ea28ed9e75a41eb456bfcb547b4e6f10e750", "tree": "e3fe4a653bd96815c650dd9f5db11edc6b39b0db", "parents": [ "641c3187b9d53cfd4c23b0ce2ab18a13d5e775e5" ], "author": { "name": "John Calixto", "email": "john.calixto@modsystems.com", "time": "Tue Apr 26 18:56:29 2011 -0400" }, "committer": { "name": "Chris Ball", "email": "cjb@laptop.org", "time": "Tue May 24 21:02:54 2011 -0400" }, "message": "mmc: core: Add mmc CMD+ACMD passthrough ioctl\n\nAllows appropriately-privileged applications to send CMD (normal) and ACMD\n(application-specific; preceded with CMD55) commands to cards/devices on\nthe mmc bus.
