The reservation behaviour differs\ndepending on whether the mapping was mapped MAP_SHARED or MAP_PRIVATE.\nFor MAP_SHARED mappings, hugepages are reserved when mmap() is first\ncalled and are tracked based on information associated with the inode.\nOther processes mapping MAP_SHARED use the same reservation. MAP_PRIVATE\ntrack the reservations based on the VMA created as part of the mmap()\noperation. Each process mapping MAP_PRIVATE must make its own\nreservation.\n\nhugetlbfs currently checks if a VMA is MAP_SHARED with the VM_SHARED flag\nand not VM_MAYSHARE. For file-backed mappings, such as hugetlbfs,\nVM_SHARED is set only if the mapping is MAP_SHARED and the file was opened\nread-write. If a shared memory mapping was mapped shared-read-write for\npopulating of data and mapped shared-read-only by other processes, then\nhugetlbfs would account for the mapping as if it was MAP_PRIVATE. This\ncauses processes to fail to map the file MAP_SHARED even though it should\nsucceed as the reservation is there.\n\nThis patch alters mm/hugetlb.c and replaces VM_SHARED with VM_MAYSHARE\nwhen the intent of the code was to check whether the VMA was mapped\nMAP_SHARED or MAP_PRIVATE.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \u003cstable@kernel.org\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \u003cstarlight@binnacle.cx\u003e\nCc: Eric B Munson \u003cebmunson@us.ibm.com\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@canonical.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "32b154c0b0bae2879bf4e549d861caf1759a3546", "tree": "dbd2c6df9511ee400c5460ef714955d15b689cf4", "parents": [ "53b7479bbdaedcc7846c66fd608fe66f1b5aa35b" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Thu May 28 14:34:37 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri May 29 08:40:03 2009 -0700" }, "message": "x86: ignore VM_LOCKED when determining if hugetlb-backed page tables can be shared or not\n\nAddresses http://bugzilla.kernel.org/show_bug.cgi?id\u003d13302\n\nOn x86 and x86-64, it is possible that page tables are shared beween\nshared mappings backed by hugetlbfs. As part of this,\npage_table_shareable() checks a pair of vma-\u003evm_flags and they must match\nif they are to be shared. All VMA flags are taken into account, including\nVM_LOCKED.\n\nThe problem is that VM_LOCKED is cleared on fork(). When a process with a\nshared memory segment forks() to exec() a helper, there will be shared\nVMAs with different flags. The impact is that the shared segment is\nsometimes considered shareable and other times not, depending on what\nprocess is checking.\n\nWhat happens is that the segment page tables are being shared but the\ncount is inaccurate depending on the ordering of events. As the page\ntables are freed with put_page(), bad pmd\u0027s are found when some of the\nchildren exit. The hugepage counters also get corrupted and the Total and\nFree count will no longer match even when all the hugepage-backed regions\nare freed. This requires a reboot of the machine to \"fix\".\n\nThis patch addresses the problem by comparing all flags except VM_LOCKED\nwhen deciding if pagetables should be shared or not for hugetlbfs-backed\nmapping.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \u003cstable@kernel.org\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \u003cstarlight@binnacle.cx\u003e\nCc: Eric B Munson \u003cebmunson@us.ibm.com\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@canonical.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "53b7479bbdaedcc7846c66fd608fe66f1b5aa35b", "tree": "9a614a00799ed41593723db1e790db7fe6bae962", "parents": [ "17663e59704bea838a9236f299104e30909a43b1" ], "author": { "name": "Nicolas Ferre", "email": "nicolas.ferre@atmel.com", "time": "Thu May 28 14:34:36 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri May 29 08:40:03 2009 -0700" }, "message": "atmel_lcdfb: correct fifo size for some products\n\nRemove wrong fifo size definition for some AT91 products.\n\nDue to a misunderstanding of some AT91 datasheets, a fifo size of 2048\n(words) has been introduced by mistake.
