That protects\nexisting code from dealing with those things.\n\nThere are two things still missing (they come in the next commits):\none is handling of symlinks (right now we refuse to open them that\nway; see the next commit for semantics related to those) and another\nis descriptor passing via SCM_RIGHTS datagrams.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "f2fa2ffc2046fdc35f96366d1ec8675f4d578522", "tree": "b1215682f5fbb99cf975cee3fb827909ee4a1c97", "parents": [ "03cb5f03dcb26846fcad345d8c15aae91579a53d" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Sat Jan 29 18:43:40 2011 +0530" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Mar 15 02:21:45 2011 -0400" }, "message": "ext4: Copy fs UUID to superblock\n\nFile system UUID is made available to application\nvia /proc/\u003cpid\u003e/mountinfo\n\nSigned-off-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "03cb5f03dcb26846fcad345d8c15aae91579a53d", "tree": "cf95badfa17be432388dd75d975339954b7bcf50", "parents": [ "93f1c20bc8cdb757be50566eff88d65c3b26881f" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Sat Jan 29 18:43:39 2011 +0530" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Mar 15 02:21:45 2011 -0400" }, "message": "ext3: Copy fs UUID to superblock.\n\nFile system UUID is made available to application\nvia /proc/\u003cpid\u003e/mountinfo\n\nSigned-off-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "93f1c20bc8cdb757be50566eff88d65c3b26881f", "tree": "15e812c8127ddd795b8112f76832f6411953be62", "parents": [ "a51571ccb8be1b88aea502ebba8350519682c16d" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Sat Jan 29 18:43:38 2011 +0530" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Mar 15 02:21:45 2011 -0400" }, "message": "vfs: Export file system uuid via /proc/\u003cpid\u003e/mountinfo\n\nWe add a per superblock uuid field.

These architectures can call\n irq_work_run() at the tail of any IRQ handlers that might enqueue such\n work (like the perf IRQ handler) to avoid undue latencies in\n processing the work.\n\nFor MIPSXX, we need to call irq_work_run() at the tail of the perf IRQ\nhandler as described above.\n\nReported-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: David Daney \u003cddaney@caviumnetworks.com\u003e\nSigned-off-by: Deng-Cheng Zhu \u003cdengcheng.zhu@gmail.com\u003e\nTo: fweisbec@gmail.com\nTo: will.deacon@arm.com\nCc: linux-mips@linux-mips.org\nCc: linux-kernel@vger.kernel.org\nCc: paulus@samba.org\nCc: mingo@elte.hu\nCc: acme@redhat.com\nCc: matt@console-pimps.org\nCc: sshtylyov@mvista.com,\nPatchwork: http://patchwork.linux-mips.org/patch/2011/\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "efe8dc556cd0f22e04c453188ffbc408b492eb82", "tree": "c0715ffdc93e3f96ae4adb3e6710bd08d5654b0b", "parents": [ "994fed2dd2166f86b62ec53c7424660145f138ee" ], "author": { "name": "Yoichi Yuasa", "email": "yuasa@linux-mips.org", "time": "Mon Feb 07 11:31:36 2011 +0900" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Mon Mar 14 21:07:26 2011 +0100" }, "message": "MIPS: Fix always CONFIG_LOONGSON_UART_BASE\u003dy\n\nSigned-off-by: Yoichi Yuasa \u003cyuasa@linux-mips.org\u003e\nCc: linux-mips \u003clinux-mips@linux-mips.org\u003e\nPatchwork: https://patchwork.linux-mips.org/patch/2055/\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "994fed2dd2166f86b62ec53c7424660145f138ee", "tree": "693b4a0483d0a4ec10a4b2ab911213c4b892b7a2", "parents": [ "d3ce0e98b7fe17bb1dec9f6d7c50213db01e7189" ], "author": { "name": "Stefan Weil", "email": "weil@mail.berlios.de", "time": "Sun Jan 30 21:41:44 2011 +0100" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Mon Mar 14 21:07:26 2011 +0100" }, "message": "MIPS: Loongson: Fix potentially wrong string handling\n\nThis error was reported by cppcheck:\narch/mips/loongson/common/machtype.c:56: error: Dangerous usage of \u0027str\u0027 (strncpy doesn\u0027t always 0-terminate it)\n\nIf strncpy copied MACHTYPE_LEN bytes, the destination string str\nwas not terminated.\n\nThe patch adds one more byte to str and makes sure that this byte is\nalways 0.\n\nSigned-off-by: Stefan Weil \u003cweil@mail.berlios.de\u003e\nCc: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Arnaud Patard \u003capatard@mandriva.com\u003e\nCc: linux-mips@linux-mips.org\nCc: linux-kernel@vger.kernel.org\nPatchwork: https://patchwork.linux-mips.org/patch/2053/\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\n" }, { "commit": "d3ce0e98b7fe17bb1dec9f6d7c50213db01e7189", "tree": "7be0c825c8f8e894c4bec17762046d1f774bb4e9", "parents": [ "91b51f30084911754aed004bd3792f71f7bf0843" ], "author": { "name": "David Daney", "email": "ddaney@caviumnetworks.com", "time": "Mon Jan 24 14:51:37 2011 -0800" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Mon Mar 14 21:07:26 2011 +0100" }, "message": "MIPS: Fix GCC-4.6 \u0027set but not used\u0027 warning in arch/mips/mm/init.c\n\nUnder some combinations of CONFIG_*, lastpfn in page_is_ram is \u0027set\nbut not used\u0027.

So,\nthe 2nd argument of prepare_ftrace_return() is not important, the real\nrequirement is the right recorded ip address should be calculated and\nassign to trace.func, this will be fixed in the next patches.\n\nReported-by: Zhiping Zhong \u003cxzhong86@163.com\u003e\nSigned-off-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Steven Rostedt \u003csrostedt@redhat.com\u003e\nCc: linux-mips@linux-mips.org\nPatchwork: https://patchwork.linux-mips.org/patch/2007/\nSigned-off-by: Ralf Baechle \u003cralf@duck.linux-mips.net\u003e\n" }, { "commit": "d9cdb2f1038143c945fcb1a366aae4fa2998419e", "tree": "f6b0e9b0dd338e1c704cd9f4c7013d9af3476acf", "parents": [ "9a620a559be65023b5fd5d0eaf37dae884c4f404" ], "author": { "name": "Wu Zhangjin", "email": "wuzhangjin@gmail.com", "time": "Thu Jan 20 03:28:29 2011 +0800" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Mon Mar 14 21:07:24 2011 +0100" }, "message": "MIPS, Tracing: Substitute in_kernel_space() for in_module()\n\nThe old in_module() may not work in some situations(e.g. when module \u0026\nkernel are in the same address space when CONFIG_MAPPED_KERNEL\u003dy), The\nin_kernel_space() is more generic and it is also easy to be implemented\nvia cloning the existing core_kernel_text(), so, replace the in_module()\nwith in_kernel_space().\n\nSigned-off-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Steven Rostedt \u003csrostedt@redhat.com\u003e\nCc: linux-mips@linux-mips.org\nPatchwork: https://patchwork.linux-mips.org/patch/2005/\nSigned-off-by: Ralf Baechle \u003cralf@duck.linux-mips.net\u003e\n" }, { "commit": "9a620a559be65023b5fd5d0eaf37dae884c4f404", "tree": "3c7e7d69c6ee14088ac8bf08499d9e8afce2710c", "parents": [ "52bd080d5c87af556bf71e3b07bdd8586166c43b" ], "author": { "name": "Wu Zhangjin", "email": "wuzhangjin@gmail.com", "time": "Thu Jan 20 03:28:27 2011 +0800" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Mon Mar 14 21:07:24 2011 +0100" }, "message": "MIPS, Tracing: Speed up function graph tracer\n\nThis simply moves the \"ip-\u003d4\" statement down to the end of the do { ...\n} while (...); loop, which reduces one unneeded subtration and the\nsubsequent memory loading and comparison.\n\nSigned-off-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nCc: Steven Rostedt \u003csrostedt@redhat.com\u003e\nCc: linux-mips@linux-mips.org\nPatchwork: https://patchwork.linux-mips.org/patch/2006/\nSigned-off-by: Ralf Baechle \u003cralf@duck.linux-mips.net\u003e\n" }, { "commit": "52bd080d5c87af556bf71e3b07bdd8586166c43b", "tree": "01ab3cb144b063f259aa8844cb7f218140ef4f79", "parents": [ "c44ed965be7a84afaa07543c04eb97a5dfe93422" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Sun Jan 23 15:17:00 2011 +0000" }, "committer": { "name": "Ralf Baechle", "email": "ralf@linux-mips.org", "time": "Mon Mar 14 21:07:24 2011 +0100" }, "message": "MIPS: Replace deprecated spinlock initialization\n\nSPIN_LOCK_UNLOCK is deprecated.

When Xen sets\nup a guest it initially populates a array which has descending\n(or ascending) MFN values, as so:\n\n idx: 0, 1, 2\n [0x290F, 0x290E, 0x290D, ..]\n\nso pfn_to_mfn(2)\u003d\u003d0x290D. If you start, restart many guests that list\nstarts looking quite random.\n\nWe graft this structure on our P2M tree structure and stick in\nthose MFN in the leafs. But for all other leaf entries, or for the top\nroot, or middle one, for which there is a void entry, we assume it is\n\"missing\". So\n pfn_to_mfn(0xc0000)\u003dINVALID_P2M_ENTRY.\n\nWe add the possibility of setting 1-1 mappings on certain regions, so\nthat:\n pfn_to_mfn(0xc0000)\u003d0xc0000\n\nThe benefit of this is, that we can assume for non-RAM regions (think\nPCI BARs, or ACPI spaces), we can create mappings easily b/c we\nget the PFN value to match the MFN.\n\nFor this to work efficiently we introduce one new page p2m_identity and\nallocate (via reserved_brk) any other pages we need to cover the sides\n(1GB or 4MB boundary violations). All entries in p2m_identity are set to\nINVALID_P2M_ENTRY type (Xen toolstack only recognizes that and MFNs,\nno other fancy value).\n\nOn lookup we spot that the entry points to p2m_identity and return the identity\nvalue instead of dereferencing and returning INVALID_P2M_ENTRY. If the entry\npoints to an allocated page, we just proceed as before and return the PFN.\nIf the PFN has IDENTITY_FRAME_BIT set we unmask that in appropriate functions\n(pfn_to_mfn).\n\nThe reason for having the IDENTITY_FRAME_BIT instead of just returning the\nPFN is that we could find ourselves where pfn_to_mfn(pfn)\u003d\u003dpfn for a\nnon-identity pfn. To protect ourselves against we elect to set (and get) the\nIDENTITY_FRAME_BIT on all identity mapped PFNs.\n\nThis simplistic diagram is used to explain the more subtle piece of code.\nThere is also a digram of the P2M at the end that can help.\nImagine your E820 looking as so:\n\n 1GB 2GB\n/-------------------+---------\\/----\\ /----------\\ /---+-----\\\n| System RAM | Sys RAM ||ACPI| | reserved | | Sys RAM |\n\\-------------------+---------/\\----/ \\----------/ \\---+-----/\n ^- 1029MB ^- 2001MB\n\n[1029MB \u003d 263424 (0x40500), 2001MB \u003d 512256 (0x7D100), 2048MB \u003d 524288 (0x80000)]\n\nAnd dom0_mem\u003dmax:3GB,1GB is passed in to the guest, meaning memory past 1GB\nis actually not present (would have to kick the balloon driver to put it in).\n\nWhen we are told to set the PFNs for identity mapping (see patch: \"xen/setup:\nSet identity mapping for non-RAM E820 and E820 gaps.\") we pass in the start\nof the PFN and the end PFN (263424 and 512256 respectively). The first step is\nto reserve_brk a top leaf page if the p2m[1] is missing. The top leaf page\ncovers 512^2 of page estate (1GB) and in case the start or end PFN is not\naligned on 512^2*PAGE_SIZE (1GB) we loop on aligned 1GB PFNs from start pfn to\nend pfn. We reserve_brk top leaf pages if they are missing (means they point\nto p2m_mid_missing).\n\nWith the E820 example above, 263424 is not 1GB aligned so we allocate a\nreserve_brk page which will cover the PFNs estate from 0x40000 to 0x80000.\nEach entry in the allocate page is \"missing\" (points to p2m_missing).\n\nNext stage is to determine if we need to do a more granular boundary check\non the 4MB (or 2MB depending on architecture) off the start and end pfn\u0027s.\nWe check if the start pfn and end pfn violate that boundary check, and if\nso reserve_brk a middle (p2m[x][y]) leaf page. This way we have a much finer\ngranularity of setting which PFNs are missing and which ones are identity.\nIn our example 263424 and 512256 both fail the check so we reserve_brk two\npages. Populate them with INVALID_P2M_ENTRY (so they both have \"missing\" values)\nand assign them to p2m[1][2] and p2m[1][488] respectively.\n\nAt this point we would at minimum reserve_brk one page, but could be up to\nthree. Each call to set_phys_range_identity has at maximum a three page\ncost. If we were to query the P2M at this stage, all those entries from\nstart PFN through end PFN (so 1029MB -\u003e 2001MB) would return INVALID_P2M_ENTRY\n(\"missing\").\n\nThe next step is to walk from the start pfn to the end pfn setting\nthe IDENTITY_FRAME_BIT on each PFN. This is done in \u0027set_phys_range_identity\u0027.\nIf we find that the middle leaf is pointing to p2m_missing we can swap it over\nto p2m_identity - this way covering 4MB (or 2MB) PFN space. At this point we\ndo not need to worry about boundary aligment (so no need to reserve_brk a middle\npage, figure out which PFNs are \"missing\" and which ones are identity), as that\nhas been done earlier. If we find that the middle leaf is not occupied by\np2m_identity or p2m_missing, we dereference that page (which covers\n512 PFNs) and set the appropriate PFN with IDENTITY_FRAME_BIT. In our example\n263424 and 512256 end up there, and we set from p2m[1][2][256-\u003e511] and\np2m[1][488][0-\u003e256] with IDENTITY_FRAME_BIT set.\n\nAll other regions that are void (or not filled) either point to p2m_missing\n(considered missing) or have the default value of INVALID_P2M_ENTRY (also\nconsidered missing). In our case, p2m[1][2][0-\u003e255] and p2m[1][488][257-\u003e511]\ncontain the INVALID_P2M_ENTRY value and are considered \"missing.\"\n\nThis is what the p2m ends up looking (for the E820 above) with this\nfabulous drawing:\n\n p2m /--------------\\\n /-----\\ | \u0026mfn_list[0],| /-----------------\\\n | 0 |------\u003e| \u0026mfn_list[1],| /---------------\\ | ~0, ~0, .. |\n |-----| | ..., ~0, ~0 | | ~0, ~0, [x]---+-----\u003e| IDENTITY [@256] |\n | 1 |---\\ \\--------------/ | [p2m_identity]+\\ | IDENTITY [@257] |\n |-----| \\ | [p2m_identity]+\\\\ | .... |\n | 2 |--\\ \\--------------------\u003e| ... | \\\\ \\----------------/\n |-----| \\ \\---------------/ \\\\\n | 3 |\\ \\ \\\\ p2m_identity\n |-----| \\ \\--------------------\u003e/---------------\\ /-----------------\\\n | .. +-\u003e+ | [p2m_identity]+--\u003e| ~0, ~0, ~0, ... |\n \\-----/ / | [p2m_identity]+--\u003e| ..., ~0 |\n / /---------------\\ | .... | \\-----------------/\n / | IDENTITY[@0] | /-+-[x], ~0, ~0.. |\n / | IDENTITY[@256]|\u003c----/ \\---------------/\n / | ~0, ~0, .... |\n | \\---------------/\n |\n p2m_missing p2m_missing\n/------------------\\ /------------\\\n| [p2m_mid_missing]+----\u003e| ~0, ~0, ~0 |\n| [p2m_mid_missing]+----\u003e| ..., ~0 |\n\\------------------/ \\------------/\n\nwhere ~0 is INVALID_P2M_ENTRY.
