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": "6b3678354647a653e669746c05765f05d2b90239", "tree": "a35beb4fddd53b82dac985d7d669ab260d87f537", "parents": [ "1f37070d3ff325827c6213e51b57f21fd5ac9d05" ], "author": { "name": "David S.

Because byte order of inode and block bitmap is\n\nThis patch:\n\nIn order to make the forthcoming changes smaller, this merges macro\ndefinisions in asm-generic/bitops/le.h for big-endian and little-endian as\nmuch as possible.\n\nThis also removes unused BITOP_WORD macro.\n\nSigned-off-by: Akinobu Mita \u003cakinobu.mita@gmail.com\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "3e50594e8e72932ad4cfcb0b3cbdf58fc3bce416", "tree": "c33044290a9161e73ac5eded5d10a27c47bbfd5f", "parents": [ "8a06dc4d52458e4a909b652ee9fe8f82d2cd87a2" ], "author": { "name": "FUJITA Tomonori", "email": "fujita.tomonori@lab.ntt.co.jp", "time": "Tue Mar 22 16:33:50 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Mar 22 17:44:09 2011 -0700" }, "message": "add the common dma_addr_t typedef to include/linux/types.h\n\nAll architectures can use the common dma_addr_t typedef now.

Calling fsync(2) on each\n file introduces unnecessary ordering constraints that result in a large\n amount of sub-optimal writeback/flush/commit behavior by the file\n system.\n\nThere are currently two ways (that I know of) to sync a single super_block:\n\n - BLKFLSBUF ioctl on the block device: That also invalidates the bdev\n mapping, which isn\u0027t usually desirable, and doesn\u0027t work for non-block\n file systems.\n - \u0027mount -o remount,rw\u0027 will call sync_filesystem as an artifact of the\n current implemention. Relying on this little-known side effect for\n something like data safety sounds foolish.\n\nBoth of these approaches require root privileges, which some applications\ndo not have (nor should they need?) given that sync(2) is an unprivileged\noperation.\n\nThis patch introduces a new system call syncfs(2) that takes an fd and\nsyncs only the file system it references. Maybe someday we can\n\n $ sync /some/path\n\nand not get\n\n sync: ignoring all arguments\n\nThe syscall is motivated by comments by Al and Christoph at the last LSF.\nsyncfs(2) seems like an

Implement an approach proposed by David Miller:\nuse an array of const pointers to refer to the individual structures, and export\nthis pointer array through the linker script rather than the structures per se.\nIt will consume 32 extra bytes per tracepoint (24 for structure padding and 8\nfor the pointers), but are less likely to break due to compiler changes.\n\nHistory:\n\ncommit 7e066fb8 tracepoints: add DECLARE_TRACE() and DEFINE_TRACE()\nadded the aligned(32) type and variable attribute to the tracepoint structures\nto deal with gcc happily aligning statically defined structures on 32-byte\nmultiples.\n\nOne attempt was to use a 8-byte alignment for tracepoint structures by applying\nboth the variable and type attribute to tracepoint structures definitions and\ndeclarations. It worked fine with gcc 4.5.1, but broke with gcc 4.4.4 and 4.4.5.\n\nThe reason is that the \"aligned\" attribute only specify the _minimum_ alignment\nfor a structure, leaving both the compiler and the linker free to align on\nlarger multiples. Because tracepoint.c expects the structures to be placed as an\narray within each section, up-alignment cause NULL-pointer exceptions due to the\nextra unexpected padding.\n\n(this patch applies on top of -tip)\n\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nAcked-by: David S.

However, for 64-bit architectures it isn\u0027t sufficient\nto return 32 bits of time_t; this isn\u0027t good insurance against the 2037\nrollover. (It also makes glibc support less convenient, since we can\u0027t\nuse glibc\u0027s handy STAT_IS_KERNEL_STAT mode.)\n\nThis change extends the two \"timespec\" fields for each of the three atime,\nmtime, and ctime fields from \"int\" to \"long\". As a result, on 32-bit\nplatforms nothing changes, and 64-bit platforms will now work as expected.\n\nThe only wrinkle is 32-bit userspace under 64-bit kernels taking advantage\nof COMPAT mode. For these, we leave the \"struct stat64\" definitions with\nthe \"int\" versions of the time_t and nsec fields, so that architectures\ncan implement compat_sys_stat64() and friends with sys_stat64(), etc.,\nand get the expected 32-bit structure layout. This requires a\nfield-by-field copy in the kernel, implemented by the code guarded\nunder __ARCH_WANT_STAT64.\n\nThis does mean that the shape of the \"struct stat\" and \"struct stat64\"\nstructures is different on a 64-bit kernel, but only one of the two\nstructures should ever be used by any given process: \"struct stat\"\nis meant for 64-bit userspace only, and \"struct stat64\" for 32-bit\nuserspace only. (On a 32-bit kernel the two structures continue to have\nthe same shape, since \"long\" is 32 bits.)\n\nThe alternative is keeping the two structures the same shape on 64-bit\nkernels, which means a 64-bit time_t in \"struct stat64\" for 32-bit\nprocesses. This is a little unnatural since 32-bit userspace can\u0027t\ndo anything with 64 bits of time_t information, since time_t is just\n\"long\", not \"int64_t\"; and in any case 32-bit userspace might expect\nto be running under a 32-bit kernel, which can\u0027t provide the high 32\nbits anyway. In the case of a 32-bit kernel we\u0027d then be extending the\nkernel\u0027s 32-bit time_t to 64 bits, then truncating it back to 32 bits\nagain in userspace, for no particular reason. And, as mentioned above,\nif we have 64-bit time_t for 32-bit processes we can\u0027t easily use glibc\u0027s\nSTAT_IS_KERNEL_STAT, since glibc\u0027s stat structure requires an embedded\n\"struct timespec\", which is a pair of \"long\" (32-bit) values in a 32-bit\nuserspace. \"Inventive\" solutions are possible, but are pretty hacky.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\n" }, { "commit": "af2951325bd6c26cb2c91943c7b11aed53504056", "tree": "def3ced35a2db4dd5a8155a833865425d74de7de", "parents": [ "ab263f47c9781a644de8b28013434b645082922e" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Nov 11 10:09:41 2009 -0500" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Sat Oct 30 08:45:43 2010 -0400" }, "message": "audit: make link()/linkat() match \"attribute change\" predicate\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "c9e2a72ff1acfdffdecb338b3d997f90c507e665", "tree": "9be4b7e6a1cb90ffa86148a3937021118a5913c0", "parents": [ "9aca0e7c8c3a8f1fa6e3058abc5465b0509f0f8e", "d63f6d1b4d3ad0d88685a5f8eb1c3cac01ddd0db" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 28 15:13:55 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 28 15:13:55 2010 -0700" }, "message": "Merge branch \u0027kbuild\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6\n\n* \u0027kbuild\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6:\n initramfs: Fix build break on symbol-prefixed archs\n initramfs: fix initramfs size calculation\n initramfs: generalize initramfs_data.xxx.S variants\n scripts/kallsyms: Enable error messages while hush up unnecessary warnings\n scripts/setlocalversion: update comment\n kbuild: Use a single clean rule for kernel and external modules\n kbuild: Do not run make clean in $(srctree)\n scripts/mod/modpost.c: fix commentary accordingly to last changes\n kbuild: Really don\u0027t clean bounds.h and asm-offsets.h\n" }, { "commit": "d57af9b2142f31a39dcfdeb30776baadfc802827", "tree": "a89233b1e57b152c9bebf7bb516dd51920602969", "parents": [ "3d9e0cf1fe007b88db55d43dfdb6839e1a029ca5" ], "author": { "name": "Michael Holzheu", "email": "holzheu@linux.vnet.ibm.com", "time": "Wed Oct 27 15:34:45 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Oct 27 18:03:17 2010 -0700" }, "message": "taskstats: use real microsecond granularity for CPU times\n\nThe taskstats interface uses microsecond granularity for the user and\nsystem time values.

termiox)\n\nThis patch converts cris to use asm-generic/ioctls.h instead of its\nown version.\n\nThe differences between the arch-specific version and the generic\nversion are as follows:\n\n- CRIS defines two ioctls: TIOCSERSETRS485 and TIOCSERWRRS485,\n kept in arch-specific portion\n- CRIS defines a different value for TIOCSRS485, kept via ifndef in generic\n- The generic version adds support for termiox\n\nCc: Mikael Starvik \u003cstarvik@axis.com\u003e\nCc: Jesper Nilsson \u003cjesper.nilsson@axis.com\u003e\nSigned-off-by: Jeff Mahoney \u003cjeffm@suse.com\u003e\nSigned-off-by: Greg
