For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time. Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" }, { "commit": "bf6ee0ae494596aaf311e8430684db85d1d2f25c", "tree": "80af10d1539d20ed00ffe19bb5af51cd6a976a19", "parents": [ "0a8fe0d756fba2953462cec6db09c81dd732d0b5" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Tue Oct 03 22:17:48 2006 +0200" }, "committer": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Tue Oct 03 22:17:48 2006 +0200" }, "message": "remove mentionings of devfs in documentation\n\nNow that devfs is removed, there\u0027s no longer any need to document how to\ndo this or that with devfs.\n\nThis patch includes some improvements by Joe Perches.\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\n" }, { "commit": "095d030cff0eafd29ee31e022d374874146a5b4c", "tree": "cec6f1906b77ed55f71933bd090097487d5da976", "parents": [ "1cfee2b3c21d71a8c20884dbb77ed343558db87f" ], "author": { "name": "Eric Sesterhenn", "email": "snakebyte@gmx.de", "time": "Sat Sep 30 23:28:05 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 01 00:39:24 2006 -0700" }, "message": "[PATCH] Off-by-one in drivers/char/mwave/mwavedd.c\n\nThis fixes two off by ones in the mwave driver, found\nvia find -iname \\*.[ch] | xargs grep \"\u003e ARRAY_SIZE(\"\n\nSigned-off-by: Eric Sesterhenn \u003csnakebyte@gmx.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "62322d2554d2f9680c8ace7bbf1f97d8fa84ad1a", "tree": "904f8b8354a4079cc1daaa355fe30200dcae9dc9", "parents": [ "d459ec0baa5d22e111dfb139c46d6d788a9eac20" ], "author": { "name": "Arjan van de Ven", "email": "arjan@infradead.org", "time": "Mon Jul 03 00:24:21 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 03 15:26:59 2006 -0700" }, "message": "[PATCH] make more file_operation structs static\n\nMark the static struct file_operations in drivers/char as const.

My scripts\nwill pick it up again in the next round.\n\nSigned-off-by: Tim Schmielau \u003ctim@physik3.uni-rostock.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5981d644209c38029df7f91eb8c61bc5952f182b", "tree": "68d05c78caee0ac9e8e9e0d569326bdbd3fb73a9", "parents": [ "0f302dc35412dc67035efc188b9d5c40711b4222" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Wed Aug 31 22:19:33 2005 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Wed Aug 31 22:19:33 2005 +0100" }, "message": "[SERIAL] Convert mwave to use serial8250_(un)?register_port\n\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "e8e1c7292ee9b64c35b3f6d7f905ca5e854aea95", "tree": "99a1e06d364c935cbb2d3b76ca0c4fc6676ba6d6", "parents": [ "67da54cf5d577c9dda835d0cf42379657d15d6c9" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Sat Jun 25 14:59:09 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Jun 25 16:25:05 2005 -0700" }, "message": "[PATCH] drivers/char/mwave/tp3780i.c: remove dead code\n\nThis patch removes some dead code found by the Coverity checker.\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3b01b47cf95682d02676efa5d0b48e759db405b3", "tree": "5838c04402ab8b2c4d92ad97f6767d8a513cebbc", "parents": [ "dbc6b5f55908d7351380bca69393f5839508ad3f" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Sat Jun 25 14:59:03 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Jun 25 16:25:03 2005 -0700" }, "message": "[PATCH] drivers/char/mwave/3780i.c: cleanups\n\nThis patch contains the following cleanups:\n- make a needlessly global function static\n- #if 0 the unused global function dsp3780I_ReadGenCfg\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c97f97b374fe07bc300dea629cba14612442c26d", "tree": "d92065bf4ecaefae6a559da15ff47383758ff685", "parents": [ "f040ffab7488c02c0806ec8808fa619d463560f9" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Sat Jun 25 14:58:55 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Jun 25 16:25:01 2005 -0700" }, "message": "[PATCH] drivers/char/mwave/tp3780i.c: remove kernel 2.2 #if\u0027s\n\nThis patch removes #if\u0027s for kernel 2.2 .\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "74880c063b06efd103c924abfe19d9d8fa4864c4", "tree": "7d0995426cec1f3577a5f8e5f61ada43a0df9813", "parents": [ "ff381d2223a30ee70752791fd9c3588d8f1cab77" ], "author": { "name": "Yani Ioannou", "email": "yani.ioannou@gmail.com", "time": "Tue May 17 06:41:12 2005 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Jun 20 15:15:32 2005 -0700" }, "message": "[PATCH] Driver Core: drivers/base - drivers/i2c/chips/adm1026.c: update device attribute callbacks\n\nSigned-off-by: Yani Ioannou \u003cyani.ioannou@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
