New in this\npatch is the realization that the only dynamic entries\nthat need to be handled have ifname as the asscii string\nand ifindex as their ctl_name.\n\nWhen a sys_sysctl is called the code now looks in the\ntranslation table converting the binary name to the\npath under /proc where the value is to be found. Opens\nthat file, and calls into a format conversion wrapper\nthat calls fop-\u003eread and then fop-\u003ewrite as appropriate.\n\nSince in practice the practically no one uses or tests\nsys_sysctl rewritting the code to be beautiful is a little\nsilly. The redeeming merit of this work is it allows us to\nrip out all of the binary sysctl syscall support from\neverywhere else in the tree. Allowing us to remove\na lot of dead (after this patch) and barely maintained code.\n\nIn addition it becomes much easier to optimize the sysctl\nimplementation for being the backing store of /proc/sys,\nwithout having to worry about sys_sysctl.\n\nSigned-off-by: Eric W.

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.

This new algorithm\u0027s update-side expense\nis similar to that of classic hierarchical RCU, and, in absence\nof read-side preemption or blocking, is exactly that of classic\nhierarchical RCU. Perhaps more important, this new algorithm\nhas a much simpler implementation, saving well over 1,000 lines\nof code compared to mainline\u0027s implementation of preemptable\nRCU, which will hopefully be retired in favor of this new\nalgorithm.\n\nThe simplifications are obtained by maintaining per-task\nnesting state for running tasks, and using a simple\nlock-protected algorithm to handle accounting when tasks block\nwithin RCU read-side critical sections, making use of lessons\nlearned while creating numerous user-level RCU implementations\nover the past 18 months.\n\nSigned-off-by: Paul E.

In addition, depending\nif ramdisks are supported or not, the messages are not at all the same.\n\nSo keep the messages more in sync with what is really doing the kernel,\nand only display a second message in case of failure. This also ensure\nthat the printk message cannot be split by other printk\u0027s.\n\nSigned-off-by: Eric Piel \u003ceric.piel@tremplin-utc.net\u003e\nAcked-by: H.

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" } ], "next": "05cfbd66d07c44865983c8b65ae9d0037d874206" }
