The patch has zero effect on the running state.\n\nSigned-off-by: Henrik Rydberg \u003crydberg@euromail.se\u003e\nCc: Nicolas Boichat \u003cnicolas@boichat.ch\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "560a64a2b501add585b494b2b9cd9f68c0636b50", "tree": "76ff9e60110a388e551f17b2071405eeea5f1c71", "parents": [ "905ffdc35e50844ab45bbc59d5302238844f8526" ], "author": { "name": "Roel Kluin", "email": "roel.kluin@gmail.com", "time": "Mon Sep 21 17:04:48 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:49 2009 -0700" }, "message": "hwmon: fix freeing of gpio_data and irq\n\nIf already requested, gpio_data and irq should be freed in the case of an\nerror.\n\nSigned-off-by: Roel Kluin \u003croel.kluin@gmail.com\u003e\nAcked-by: Jonathan Cameron \u003cjic23@cam.ac.uk\u003e\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "905ffdc35e50844ab45bbc59d5302238844f8526", "tree": "13f5fcb88fe9b8f049181234749ea715b509e34b", "parents": [ "f266889517252bc697e7103bcd6ed46bdf2c1579" ], "author": { "name": "Michael Abbott", "email": "michael@araneidae.co.uk", "time": "Mon Sep 21 17:04:47 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:49 2009 -0700" }, "message": "drivers/hwmon/adm1021.c: add low_power support for adm1021 driver\n\nOccasionally it is helpful to be able to turn a temperature sensor off\n(for example if it\u0027s making unwanted electrical noise).

This mapping will borrow\nfunctionality from the huge page shm code to create a file on the kernel\ninternal mount and use it to approximate an anonymous mapping. The\nMAP_HUGETLB flag is a modifier to MAP_ANONYMOUS and will not work without\nboth flags being preset.\n\nA new flag is necessary because there is no other way to hook into huge\npages without creating a file on a hugetlbfs mount which wouldn\u0027t be\nMAP_ANONYMOUS.\n\nTo userspace, this mapping will behave just like an anonymous mapping\nbecause the file is not accessible outside of the kernel.\n\nThis patchset is meant to simplify the programming model. Presently there\nis a large chunk of boiler platecode, contained in libhugetlbfs, required\nto create private, hugepage backed mappings. This patch set would allow\nuse of hugepages without linking to libhugetlbfs or having hugetblfs\nmounted.\n\nUnification of the VM code would provide these same benefits, but it has\nbeen resisted each time that it has been suggested for several reasons: it\nwould break PAGE_SIZE assumptions across the kernel, it makes page-table\nabstractions really expensive, and it does not provide any benefit on\narchitectures that do not support huge pages, incurring fast path\npenalties without providing any benefit on these architectures.\n\nThis patch:\n\nThere are two means of creating mappings backed by huge pages:\n\n 1. mmap() a file created on hugetlbfs\n 2. Use shm which creates a file on an internal mount which essentially\n maps it MAP_SHARED\n\nThe internal mount is only used for shared mappings but there is very\nlittle that stops it being used for private mappings. This patch extends\nhugetlbfs_file_setup() to deal with the creation of files that will be\nmapped MAP_PRIVATE on the internal hugetlbfs mount.

On the SLES11 kernel\n[2.6.27.19+] with Barcelona processors, as we increased the load [10s of\nthousands of tasks], the throughput would vary between two \"plateaus\"--one\nat ~65K jobs per minute and one at ~130K jpm. The simple patch below\ncauses the results to smooth out at the ~130k plateau.\n\nBut wait, there\u0027s more:\n\nWe do not see this behavior on smaller platforms--e.g., 4 socket/8 core.\nThis could be the result of the larger number of cpus on the larger\nplatform--a scalability issue--or it could be the result of the larger\nnumber of interconnect \"hops\" between some nodes in this platform and how\nthe tasks for a given load end up distributed over the nodes\u0027 cpus and\nmemories--a stochastic NUMA effect.\n\nThe variability in the results are less pronounced [on the same platform]\nwith Shanghai processors and with mainline kernels. With 31-rc6 on\nShanghai processors and 288 file systems on 288 fibre attached storage\nvolumes, the curves [jpm vs load] are both quite flat with the patched\nkernel consistently producing ~3.9% better throughput [~80K jpm vs ~77K\njpm] than the unpatched kernel.\n\nProfiling indicated that the \"slow\" runs were incurring high[er]\ncontention on an anon_vma lock in vma_adjust(), apparently called from the\nsbrk() system call.\n\nThe patch:\n\nA comment in mm/mmap.c:vma_adjust() suggests that we don\u0027t really need the\nanon_vma lock when we\u0027re only adjusting the end of a vma, as is the case\nfor brk(). The comment questions whether it\u0027s worth while to optimize for\nthis case. Apparently, on the newer, larger x86_64 platforms, with\ninteresting NUMA topologies, it is worth while--especially considering\nthat the patch [if correct!] is quite simple.\n\nWe can detect this condition--no overlap with next vma--by noting a NULL\n\"importer\". The anon_vma pointer will also be NULL in this case, so\nsimply avoid loading vma-\u003eanon_vma to avoid the lock.\n\nHowever, we DO need to take the anon_vma lock when we\u0027re inserting a vma\n[\u0027insert\u0027 non-NULL] even when we have no overlap [NULL \"importer\"], so we\nneed to check for \u0027insert\u0027, as well. And Hugh points out that we should\nalso take it when adjusting vm_start (so that rmap.c can rely upon\nvma_address() while it holds the anon_vma lock).\n\nakpm: Zhang Yanmin reprts a 150% throughput improvement with aim7, so it\nmight be -stable material even though thiss isn\u0027t a regression: \"this\nissue is not clear on dual socket Nehalem machine (2*4*2 cpu), but is\nsevere on large machine (4*8*2 cpu)\"\n\n[hugh.dickins@tiscali.co.uk: test vma start too]\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nSigned-off-by: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Eric Whitney \u003ceric.whitney@hp.com\u003e\nTested-by: \"Zhang, Yanmin\" \u003cyanmin_zhang@linux.intel.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "3f96b79ad96263cc0ece7bb340cddf9b2ddfb1b3", "tree": "0da9828c16543164f1b055fd927ea3e222ca05e5", "parents": [ "cdf7b3418ad5a8783efe8f9124023d9b869fec0f" ], "author": { "name": "Hugh Dickins", "email": "hugh.dickins@tiscali.co.uk", "time": "Mon Sep 21 17:03:37 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:41 2009 -0700" }, "message": "tmpfs: depend on shmem\n\nCONFIG_SHMEM off gives you (ramfs masquerading as) tmpfs, even when\nCONFIG_TMPFS is off: that\u0027s a little anomalous, and I\u0027d intended to make\nmore sense of it by removing CONFIG_TMPFS altogether, always enabling its\ncode when CONFIG_SHMEM;
