Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros.

Specifically, each anon_vma will be shared between the parent\nprocess and all its child processes.\n\nIn a workload with 1000 child processes and a VMA with 1000 anonymous\npages per process that get COWed, this leads to a system with a million\nanonymous pages in the same anon_vma, each of which is mapped in just one\nof the 1000 processes. However, the current rmap code needs to walk them\nall, leading to O(N) scanning complexity for each page.\n\nThis can result in systems where one CPU is walking the page tables of\n1000 processes in page_referenced_one, while all other CPUs are stuck on\nthe anon_vma lock. This leads to catastrophic failure for a benchmark\nlike AIM7, where the total number of processes can reach in the tens of\nthousands. Real workloads are still a factor 10 less process intensive\nthan AIM7, but they are catching up.\n\nThis patch changes the way anon_vmas and VMAs are linked, which allows us\nto associate multiple anon_vmas with a VMA. At fork time, each child\nprocess gets its own anon_vmas, in which its COWed pages will be\ninstantiated. The parents\u0027 anon_vma is also linked to the VMA, because\nnon-COWed pages could be present in any of the children.\n\nThis reduces rmap scanning complexity to O(1) for the pages of the 1000\nchild processes, with O(N) complexity for at most 1/N pages in the system.\n This reduces the average scanning cost in heavily forking workloads from\nO(N) to 2.\n\nThe only real complexity in this patch stems from the fact that linking a\nVMA to anon_vmas now involves memory allocations. This means vma_adjust\ncan fail, if it needs to attach a VMA to anon_vma structures. This in\nturn means error handling needs to be added to the calling functions.\n\nA second source of complexity is that, because there can be multiple\nanon_vmas, the anon_vma linking in vma_adjust can no longer be done under\n\"the\" anon_vma lock. To prevent the rmap code from walking up an\nincomplete VMA, this patch introduces the VM_LOCK_RMAP VMA flag. This bit\nflag uses the same slot as the NOMMU VM_MAPPED_COPY, with an ifdef in mm.h\nto make sure it is impossible to compile a kernel that needs both symbolic\nvalues for the same bitflag.\n\nSome test results:\n\nWithout the anon_vma changes, when AIM7 hits around 9.7k users (on a test\nbox with 16GB RAM and not quite enough IO), the system ends up running\n\u003e99% in system time, with every CPU on the same anon_vma lock in the\npageout code.\n\nWith these changes, AIM7 hits the cross-over point around 29.7k users.\nThis happens with ~99% IO wait time, there never seems to be any spike in\nsystem time. The anon_vma lock contention appears to be resolved.\n\n[akpm@linux-foundation.org: cleanups]\nSigned-off-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: KOSAKI Motohiro

It will be a real problem in kdump cases where INIT might\n be asserted to unstable APs going to be offline by returning to SAL.\n\nDescription:\n\n Since psr.mc is cleared when bits in psr are set to SAL_PSR_BITS_TO_SET\n in ia64_jump_to_sal(), there is a small window (~few msecs) that the\n cpu can receive INIT even if the cpu enter there via INIT handler.\n In this window we do restore of registers for SAL, so INIT asserted\n here will not work properly.\n\n It is hard to remove this window by masking INIT (i.e. setting psr.mc)\n because we have to unmask it later in OS, because we have to use branch\n instruction (br.ret, not rfi) to return SAL, due to OS_BOOT_RENDEZ to\n SAL return convention.\n\n I suppose this window will not be a real problem on cpu offline if we\n can educate people not to push INIT button during hotplug operation.\n However, only exception is a race in kdump and INIT. Now kdump returns\n APs to SAL before processing dump, but the kernel might receive INIT at\n that point in time. Such INIT might be asserted by kdump itself if an\n AP doesn\u0027t react IPI soon and kdump decided to use INIT to stop the AP.\n Or it might be asserted by operator or an external agent to start dump\n on the unstable system.\n\n Such panic+INIT or INIT+INIT cases should be rare, but it will be happy\n if we can retrieve crashdump even in such cases.\n\nHow to reproduce:\n\n panic+INIT or INIT+INIT, with kdump configured\n\nExpected results:\n\n crashdump is retrieved anyway\n\nActual results:\n\n panic, hang etc. (unexpected)\n\nProposed fix\n\n To avoid the window on the way to SAL, this patch stops returning APs\n to SAL in case of kdump. In other words, this patch makes APs spin\n in OS instead of spinning in SAL.\n\n (* Note: What impact would be there? If a cpu is spinning in SAL,\n the cpu is in BOOT_RENDEZ loop, as same as offlined cpu.\n In theory if an INIT is asserted there, cpus in the BOOT_RENDEZ loop\n should not invoke OS_INIT on it. So in either way, no matter where\n the cpu is spinning actually in, once cpu starts spin and act as\n \"frozen,\" INIT on the cpu have no effects.\n From another point of view, all debug information on the cpu should\n have stored to memory before the cpu start to be frozen. So no more\n action on the cpu is required.)\n\n I confirmed that the kdump sometime hangs by concurrent INITs (another\n INIT after an INIT), and it doesn\u0027t hang after applying this patch.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nCc: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: Haren Myneni \u003chbabu@us.ibm.com\u003e\nCc: kexec@lists.infradead.org\nAcked-by: Fenghua Yu \u003cfenghua.yu@intel.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "6cc3efcdf01cf874ffe770919395918a3ee9365b", "tree": "96a04f965ea57eaba6625f5d91e069563ad6ebbc", "parents": [ "07a6a4ae827b54cec4c1b1d92bed1cc9176b45ec" ], "author": { "name": "Hidetoshi Seto", "email": "[seto.hidetoshi@jp.fujitsu.com]", "time": "Thu Aug 06 14:51:57 2009 -0700" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Mon Sep 14 16:18:17 2009 -0700" }, "message": "[IA64] kexec: Unregister MCA handler before kexec\n\nSummary:\n\n MCA on the beginning of kdump/kexec kernel will result in unexpected\n behavior because MCA handler for previous kernel is invoked on the\n kdump kernel.\n\nDescription:\n\n Once a cpu is passed to new kernel, all resources in previous kernel\n should not be used from the cpu.
