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. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "5ab116c9349ef52d6fbd2e2917a53f13194b048e", "tree": "636a6cf02d5ca47c6da5d4935b07ddf08666a09c", "parents": [ "5574169613b40b85d6f4c67208fa4846b897a0a1" ], "author": { "name": "Miao Xie", "email": "miaox@cn.fujitsu.com", "time": "Tue Mar 23 13:35:34 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 24 16:31:21 2010 -0700" }, "message": "cpuset: fix the problem that cpuset_mem_spread_node() returns an offline node\n\ncpuset_mem_spread_node() returns an offline node, and causes an oops.\n\nThis patch fixes it by initializing task-\u003emems_allowed to\nnode_states[N_HIGH_MEMORY], and updating task-\u003emems_allowed when doing\nmemory hotplug.\n\nSigned-off-by: Miao Xie \u003cmiaox@cn.fujitsu.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nReported-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nTested-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\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": "7463e633c5f94792dcff1afefb0d2961318a9d09", "tree": "db2ee59033f50dfe2b3ebe48c08cefef86720bc8", "parents": [ "cfd8d6c0ed89ba387609419e3d8d4c6b92a5d446" ], "author": { "name": "H Hartley Sweeten", "email": "hartleys@visionengravers.com", "time": "Fri Mar 05 13:42:46 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:32 2010 -0800" }, "message": "init/main.c: make setup_max_cpus static for !SMP\n\nThe only in tree external users of the symbol setup_max_cpus are in\narch/x86/.

Because the memory policy is applied in the process\u0027s\ncontext originally. After applying this patch, one task directly\nmanipulates anothers mems_allowed, and we use alloc_lock in the\ntask_struct to protect mems_allowed and memory policy of the task.\n\nBut in the fast path, we didn\u0027t use lock to protect them, because adding a\nlock may lead to performance regression. But if we don\u0027t add a lock,the\ntask might see no nodes when changing cpuset\u0027s mems_allowed to some\nnon-overlapping set. In order to avoid it, we set all new allowed nodes,\nthen clear newly disallowed ones.\n\n[lee.schermerhorn@hp.com:\n The rework of mpol_new() to extract the adjusting of the node mask to\n apply cpuset and mpol flags \"context\" breaks set_mempolicy() and mbind()\n with MPOL_PREFERRED and a NULL nodemask--i.e., explicit local\n allocation.

So base addresses,\ninterrupts and other configuration can be kept with the processor or board\ncode, and the platform driver can be reused by many different platforms.\n\nFor early devices we have nothing today. For instance, to configure early\ntimers and early serial ports we cannot use platform devices. This\nbecause the setup order during boot. Timers are needed before the\nplatform driver core code is available. The same goes for early printk\nsupport. Early in this case means before initcalls.\n\nThese early drivers today have their configuration either hard coded or\nthey receive it using some special configuration method. This is working\nquite well, but if we want to support both regular kernel modules and\nearly devices then we need to have two ways of configuring the same\ndriver. A single way would be better.\n\nThe early platform driver patch is basically a set of functions that allow\ndrivers to register themselves and architecture code to locate them and\nprobe. Registration happens through early_param(). The time for the\nprobe is decided by the architecture code.\n\nSee Documentation/driver-model/platform.txt for more details.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Magnus Damm \u003cdamm@igel.co.jp\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nCc: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "02af61bb50f5d5f0322dbe5ab2a0d75808d25c7b", "tree": "fa087ed8a584d7b66016e6a1421e538369d52e5a", "parents": [ "abd41443ac76d3e9c29a8c1d9e9a3312306cc55e" ], "author": { "name": "Zhaolei", "email": "zhaolei@cn.fujitsu.com", "time": "Fri Apr 10 14:26:18 2009 +0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Apr 12 15:22:55 2009 +0200" }, "message": "tracing, kmemtrace: Separate include/trace/kmemtrace.h to kmemtrace part and tracepoint part\n\nImpact: refactor code for future changes\n\nCurrent kmemtrace.h is used both as header file of kmemtrace and kmem\u0027s\ntracepoints definition.\n\nTracepoints\u0027 definition file may be used by other code, and should only have\ndefinition of tracepoint.\n\nWe can separate include/trace/kmemtrace.h into 2 files:\n\n include/linux/kmemtrace.h: header file for kmemtrace\n include/trace/kmem.h: definition of kmem tracepoints\n\nSigned-off-by: Zhao Lei \u003czhaolei@cn.fujitsu.com\u003e\nAcked-by: Eduard -

And cleans up the variable-name\nand function-name language. ;-)\n\nThe boot CPU runs in the context of its idle thread during boot-up.\nDuring this time, idle_cpu(0) will always return nonzero, which will\nfool Classic and Hierarchical RCU into deciding that a large chunk of\nthe boot-up sequence is a big long quiescent state. This in turn causes\nRCU to prematurely end grace periods during this time.\n\nThis patch changes the rcutree.c and rcuclassic.c rcu_check_callbacks()\nfunction to ignore the idle task as a quiescent state until the\nsystem has started up the scheduler in rest_init(), introducing a\nnew non-API function rcu_idle_now_means_idle() to inform RCU of this\ntransition. RCU maintains an internal rcu_idle_cpu_truthful variable\nto track this state, which is then used by rcu_check_callback() to\ndetermine if it should believe idle_cpu().\n\nBecause this patch has the effect of disallowing RCU grace periods\nduring long stretches of the boot-up sequence, this patch also introduces\nJosh Triplett\u0027s UP-only optimization that makes synchronize_rcu() be a\nno-op if num_online_cpus() returns 1. This allows boot-time code that\ncalls synchronize_rcu() to proceed normally. Note, however, that RCU\ncallbacks registered by call_rcu() will likely queue up until later in\nthe boot sequence. Although rcuclassic and rcutree can also use this\nsame optimization after boot completes, rcupreempt must restrict its\nuse of this optimization to the portion of the boot sequence before the\nscheduler starts up, given that an rcupreempt RCU read-side critical\nsection may be preeempted.\n\nIn addition, this patch takes Nick Piggin\u0027s suggestion to make the\nsystem_state global variable be __read_mostly.\n\nChanges since v4:\n\no\tChanges the name of the introduced function and variable to\n\tbe less emotional. ;-)\n\nChanges since v3:\n\no\tWARN_ON(nr_context_switches() \u003e 0) to verify that RCU\n\tswitches out of boot-time mode before the first context\n\tswitch, as suggested by Nick Piggin.\n\nChanges since v2:\n\no\tCreated rcu_blocking_is_gp() internal-to-RCU API that\n\tdetermines whether a call to synchronize_rcu() is itself\n\ta grace period.\n\no\tThe definition of rcu_blocking_is_gp() for rcuclassic and\n\trcutree checks to see if but a single CPU is online.\n\no\tThe definition of rcu_blocking_is_gp() for rcupreempt\n\tchecks to see both if but a single CPU is online and if\n\tthe system is still in early boot.\n\n\tThis allows rcupreempt to again work correctly if running\n\ton a single CPU after booting is complete.\n\no\tAdded check to rcupreempt\u0027s synchronize_sched() for there\n\tbeing but one online CPU.\n\nTested all three variants both SMP and !SMP, booted fine, passed a short\nrcutorture test on both x86 and Power.\n\nLocated-by: Vegard Nossum \u003cvegard.nossum@gmail.com\u003e\nTested-by: Vegard Nossum \u003cvegard.nossum@gmail.com\u003e\nTested-by: Paul E.

up kernel boot\n\nRight now, most of the kernel boot is strictly synchronous, such that\nvarious hardware delays are done sequentially.\n\nIn order to make the kernel boot faster, this patch introduces\ninfrastructure to allow doing some of the initialization steps\nasynchronously, which will hide significant portions of the hardware delays\nin practice.\n\nIn order to not change device order and other similar observables, this\npatch does NOT do full parallel initialization.\n\nRather, it operates more in the way an out of order CPU does; the work may\nbe done out of order and asynchronous, but the observable effects\n(instruction retiring for the CPU) are still done in the original sequence.\n\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\n" }, {
