The patch below removes this\ninclude, resulting in some 250 to 300 files (around half) of the kernel\nthen omitting asm/irq.h.\n\nMy test builds still succeed, provided two ARM files are fixed\n(arch/arm/kernel/traps.c and arch/arm/mm/fault.c) - so there may be\nnegative impacts for this on other architectures.\n\nNote that x86 does not include asm/irq.h nor linux/hardirq.h in its\nasm/local.h, so this patch can be viewed as bringing the generic version\ninto line with the x86 version.\n\n[kosaki.motohiro@jp.fujitsu.com: add #include \u003clinux/irqflags.h\u003e to

Inspired from the Linux Kernel\nMarkers. Allows complete typing verification by declaring both tracing\nstatement inline functions and probe registration/unregistration static\ninline functions within the same macro \"DEFINE_TRACE\". No format string\nis required. See the tracepoint Documentation and Samples patches for\nusage examples.\n\nTaken from the documentation patch :\n\n\"A tracepoint placed in code provides a hook to call a function (probe)\nthat you can provide at runtime. A tracepoint can be \"on\" (a probe is\nconnected to it) or \"off\" (no probe is attached). When a tracepoint is\n\"off\" it has no effect, except for adding a tiny time penalty (checking\na condition for a branch) and space penalty (adding a few bytes for the\nfunction call at the end of the instrumented function and adds a data\nstructure in a separate section). When a tracepoint is \"on\", the\nfunction you provide is called each time the tracepoint is executed, in\nthe execution context of the caller. When the function provided ends its\nexecution, it returns to the caller (continuing from the tracepoint\nsite).\n\nYou can put tracepoints at important locations in the code. They are\nlightweight hooks that can pass an arbitrary number of parameters, which\nprototypes are described in a tracepoint declaration placed in a header\nfile.\"\n\nAddition and removal of tracepoints is synchronized by RCU using the\nscheduler (and preempt_disable) as guarantees to find a quiescent state\n(this is really RCU \"classic\"). The update side uses rcu_barrier_sched()\nwith call_rcu_sched() and the read/execute side uses\n\"preempt_disable()/preempt_enable()\".\n\nWe make sure the previous array containing probes, which has been\nscheduled for deletion by the rcu callback, is indeed freed before we\nproceed to the next update. It therefore limits the rate of modification\nof a single tracepoint to one update per RCU period. The objective here\nis to permit fast batch add/removal of probes on _different_\ntracepoints.\n\nChangelog :\n- Use #name \":\" #proto as string to identify the tracepoint in the\n tracepoint table. This will make sure not type mismatch happens due to\n connexion of a probe with the wrong type to a tracepoint declared with\n the same name in a different header.\n- Add tracepoint_entry_free_old.\n- Change __TO_TRACE to get rid of the \u0027i\u0027 iterator.\n\nMasami Hiramatsu \u003cmhiramat@redhat.com\u003e :\nTested on x86-64.\n\nPerformance impact of a tracepoint : same as markers, except that it\nadds about 70 bytes of instructions in an unlikely branch of each\ninstrumented function (the for loop, the stack setup and the function\ncall). It currently adds a memory read, a test and a conditional branch\nat the instrumentation site (in the hot path). Immediate values will\neventually change this into a load immediate, test and branch, which\nremoves the memory read which will make the i-cache impact smaller\n(changing the memory read for a load immediate removes 3-4 bytes per\nsite on x86_32 (depending on mov prefixes), or 7-8 bytes on x86_64, it\nalso saves the d-cache hit).\n\nAbout the performance impact of tracepoints (which is comparable to\nmarkers), even without immediate values optimizations, tests done by\nHideo Aoki on ia64 show no regression. His test case was using hackbench\non a kernel where scheduler instrumentation (about 5 events in code\nscheduler code) was added.\n\nQuoting Hideo Aoki about Markers :\n\nI evaluated overhead of kernel marker using linux-2.6-sched-fixes git\ntree, which includes several markers for LTTng, using an ia64 server.\n\nWhile the immediate trace mark feature isn\u0027t implemented on ia64, there\nis no major performance regression. So, I think that we don\u0027t have any\nissues to propose merging marker point patches into Linus\u0027s tree from\nthe viewpoint of performance impact.\n\nI prepared two kernels to evaluate. The first one was compiled without\nCONFIG_MARKERS. The second one was enabled CONFIG_MARKERS.\n\nI downloaded the original hackbench from the following URL:\nhttp://devresources.linux-foundation.org/craiger/hackbench/src/hackbench.c\n\nI ran hackbench 5 times in each condition and calculated the average and\ndifference between the kernels.\n\n The parameter of hackbench: every 50 from 50 to 800\n The number of CPUs of the server: 2, 4, and 8\n\nBelow is the results. As you can see, major performance regression\nwasn\u0027t found in any case. Even if number of processes increases,\ndifferences between marker-enabled kernel and marker- disabled kernel\ndoesn\u0027t increase. Moreover, if number of CPUs increases, the differences\ndoesn\u0027t increase either.\n\nCuriously, marker-enabled kernel is better than marker-disabled kernel\nin more than half cases, although I guess it comes from the difference\nof memory access pattern.\n\n* 2 CPUs\n\nNumber of | without | with | diff | diff |\nprocesses | Marker [Sec] | Marker [Sec] | [Sec] | [%]

So I\nCC\u0027ed this to KVM camp. Comments are appreciated.\n\nA pointer to dma_mapping_ops to struct dev_archdata is added. If the\npointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it\u0027s\nNULL, the system-wide dma_ops pointer is used as before.\n\nIf it\u0027s useful for KVM people, I plan to implement a mechanism to register\na hook called when a new pci (or dma capable) device is created (it works\nwith hot plugging). It enables IOMMUs to set up an appropriate\ndma_mapping_ops per device.\n\nThe major obstacle is that dma_mapping_error doesn\u0027t take a pointer to the\ndevice unlike other DMA operations. So x86 can\u0027t have dma_mapping_ops per\ndevice. Note all the POWER IOMMUs use the same dma_mapping_error function\nso this is not a problem for POWER but x86 IOMMUs use different\ndma_mapping_error functions.\n\nThe first patch adds the device argument to dma_mapping_error. The patch\nis trivial but large since it touches lots of drivers and dma-mapping.h in\nall the architecture.\n\nThis patch:\n\ndma_mapping_error() doesn\u0027t take a pointer to the device unlike other DMA\noperations. So we can\u0027t have dma_mapping_ops per device.\n\nNote that POWER already has dma_mapping_ops per device but all the POWER\nIOMMUs use the same dma_mapping_error function. x86 IOMMUs use device\nargument.\n\n[akpm@linux-foundation.org: fix sge]\n[akpm@linux-foundation.org: fix svc_rdma]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix bnx2x]\n[akpm@linux-foundation.org: fix s2io]\n[akpm@linux-foundation.org: fix pasemi_mac]\n[akpm@linux-foundation.org: fix sdhci]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix sparc]\n[akpm@linux-foundation.org: fix ibmvscsi]\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Muli Ben-Yehuda \u003cmuli@il.ibm.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Avi Kivity \u003cavi@qumranet.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fb5e2b379732e1a6ea32392980bb42e0212db842", "tree": "ce9506474dcd426ea0102836e9b719d7cb73a844", "parents": [ "37a4c940749670671adab211a2d9c9fed9f3f757" ], "author": { "name": "Jan Beulich", "email": "jbeulich@novell.com", "time": "Wed Jun 18 12:36:01 2008 +0100" }, "committer": { "name": "Sam Ravnborg", "email": "sam@ravnborg.org", "time": "Fri Jul 25 22:12:37 2008 +0200" }, "message": "vmlinux.lds: move __attribute__((__cold__)) functions back into final .text section\n\nDue to the addition of __attribute__((__cold__)) to a few symbols\nwithout adjusting the linker scripts, those symbols currently may end\nup outside the [_stext,_etext) range, as they get placed in\n.text.unlikely by (at least) gcc 4.3.0.

This has the effect of marking the pte as non-present,\nwhich will prevent the hardware from updating its state. When the new\nvalue is written back, the pte will be present again, and the hardware\ncan resume updating the access/dirty flags.\n\nWhen running in a virtualized environment, pagetable updates are\nrelatively expensive, since they generally involve some trap into the\nhypervisor. To mitigate the cost of these updates, we tend to batch\nthem.\n\nHowever, because of the atomic nature of ptep_get_and_clear(), it is\ninherently non-batchable. This new interface allows batching by\ngiving the underlying implementation enough information to open a\ntransaction between the read and write phases:\n\nptep_modify_prot_start() returns the current pte value, and puts the\n pte entry into a state where either the hardware will not update the\n pte, or if it does, the updates will be preserved on commit.\n\nptep_modify_prot_commit() writes back the updated pte, makes sure that\n any hardware updates made since ptep_modify_prot_start() are\n preserved.\n\nptep_modify_prot_start() and _commit() must be exactly paired, and\nused while holding the appropriate pte lock. They do not protect\nagainst other software updates of the pte in any way.\n\nThe current implementations of ptep_modify_prot_start and _commit are\nfunctionally unchanged from before: _start() uses ptep_get_and_clear()\nfetch the pte and zero the entry, preventing any hardware updates.\n_commit() simply writes the new pte value back knowing that the\nhardware has not updated the pte in the meantime.\n\nThe only current user of this interface is mprotect\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nAcked-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nAcked-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "6d72b7952fa7d7c61d021398970c29afde6a4443", "tree": "31c00be8e2837e2db2e62c694421a93a9f4c79d7", "parents": [ "6360b1fbb4a939efd34fc770c2ebd927c55506e0", "066519068ad2fbe98c7f45552b1f592903a9c8c8" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jun 16 11:24:00 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jun 16 11:24:00 2008 +0200" }, "message": "Merge branch \u0027linus\u0027 into core/rodata\n" }, { "commit": "e1a2a51e684bfe9d6165992d4a065439617a3107", "tree": "4d05a1b9ebadd0ab22e0e42ee3b053dddf11baf1", "parents": [ "273c11270d3715c4c06d4df1607a1a60034d887b" ], "author": { "name": "Rafael J.

However, drivers for external chips (on I2C and\nSPI busses) should be updated if they can be built as modules.\n\nSigned-off-by: Guennadi Liakhovetski \u003cg.liakhovetski@pengutronix.de\u003e\n[ gpio_ensure_requested() needs to update module usecounts too ]\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "d57594c203b1e7b54373080a797f0cbfa4aade68" }
