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

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.

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.

In the\nnormal situation for an IRQ driven serial port at typical speeds the\nbehaviour is pretty much the same, two buffers end up allocated and the\nkernel cycles between them as before.\n\nWhen there are delays or at high speed we now behave far better as the\nbuffer pool can grow a bit rather than lose characters. This also means\nthat we can operate at higher speeds reliably.\n\nFor drivers that receive characters in blocks (DMA based, USB and\nespecially virtualisation) the layer allows a lot of driver specific\ncode that works around the tty layer with private secondary queues to be\nremoved. The IBM folks need this sort of layer, the smart serial port\npeople do, the virtualisers do (because a virtualised tty typically\noperates at infinite speed rather than emulating 9600 baud).\n\nFinally many drivers had invalid and unsafe attempts to avoid buffer\noverflows by directly invoking tty methods extracted out of the innards\nof work queue structs. These are no longer needed and all go away. That\nfixes various random hangs with serial ports on overflow.\n\nThe other change in here is to optimise the receive_room path that is\nused by some callers. It turns out that only one ldisc uses receive room\nexcept asa constant and it updates it far far less than the value is\nread. We thus make it a variable not a function call.\n\nI expect the code to contain bugs due to the size alone but I\u0027ll be\nwatching and squashing them and feeding out new patches as it goes.\n\nBecause the buffers now dynamically expand you should only run out of\nbuffering when the kernel runs out of memory for real. That means a lot of\nthe horrible hacks high performance drivers used to do just aren\u0027t needed any\nmore.\n\nDescription:\n\ntty_insert_flip_char is an old API and continues to work as before, as does\ntty_flip_buffer_push() [this is why many drivers dont need modification]. It\ndoes now also return the number of chars inserted\n\nThere are also\n\ntty_buffer_request_room(tty, len)\n\nwhich asks for a buffer block of the length requested and returns the space\nfound. This improves efficiency with hardware that knows how much to\ntransfer.\n\nand tty_insert_flip_string_flags(tty, str, flags, len)\n\nto insert a string of characters and flags\n\nFor a smart interface the usual code is\n\n len \u003d tty_request_buffer_room(tty, amount_hardware_says);\n tty_insert_flip_string(tty, buffer_from_card, len);\n\nMore description!\n\nAt the moment tty buffers are attached directly to the tty. This is causing a\nlot of the problems related to tty layer locking, also problems at high speed\nand also with bursty data (such as occurs in virtualised environments)\n\nI\u0027m working on ripping out the flip buffers and replacing them with a pool of\ndynamically allocated buffers. This allows both for old style \"byte I/O\"\ndevices and also helps virtualisation and smart devices where large blocks of\ndata suddenely materialise and need storing.\n\nSo far so good. Lots of drivers reference tty-\u003eflip.*. Several of them also\ncall directly and unsafely into function pointers it provides. This will all\nbreak. Most drivers can use tty_insert_flip_char which can be kept as an API\nbut others need more.\n\nAt the moment I\u0027ve added the following interfaces, if people think more will\nbe needed now is a good time to say\n\n int tty_buffer_request_room(tty, size)\n\nTry and ensure at least size bytes are available, returns actual room (may be\nzero). At the moment it just uses the flipbuf space but that will change.\nRepeated calls without characters being added are not cumulative. (ie if you\ncall it with 1, 1, 1, and then 4 you\u0027ll have four characters of space. The\nother functions will also try and grow buffers in future but this will be a\nmore efficient way when you know block sizes.\n\n int tty_insert_flip_char(tty, ch, flag)\n\nAs before insert a character if there is room. Now returns 1 for success, 0\nfor failure.\n\n int tty_insert_flip_string(tty, str, len)\n\nInsert a block of non error characters. Returns the number inserted.\n\n int tty_prepare_flip_string(tty, strptr, len)\n\nAdjust the buffer to allow len characters to be added. Returns a buffer\npointer in strptr and the length available. This allows for hardware that\nneeds to use functions like insl or mencpy_fromio.\n\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nCc: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nSigned-off-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: John Hawkes \u003chawkes@sgi.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\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": "c889b89619339636240227abb9ee5c9ec1167a1a", "tree": "b5c9dcda9140bdd2f67e233abd5174c5289b9dab", "parents": [ "db93a82fa9d8b4d6e31c227922eaae829253bb88" ], "author": { "name": "Russell King", "email": "rmk@dyn-67.arm.linux.org.uk", "time": "Mon Nov 21 17:05:21 2005 +0000" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Mon Nov 21 17:05:21 2005 +0000" }, "message": "[SERIAL] imx: Fix missed platform_driver_unregister\n\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "3ae5eaec1d2d9c0cf53745352e7d4b152810ba24", "tree": "d8825be54cefb6ad6707478d719c8e30605bee7b", "parents": [ "00d3dcdd96646be6059cc21f2efa94c4edc1eda5" ], "author": { "name": "Russell King", "email": "rmk@dyn-67.arm.linux.org.uk", "time": "Wed Nov 09 22:32:44 2005 +0000" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Wed Nov 09 22:32:44 2005 +0000" }, "message": "[DRIVER MODEL] Convert platform drivers to use struct platform_driver\n\nThis allows us to eliminate the casts in the drivers, and eventually\nremove the use of the device_driver function pointer methods for\nplatform device drivers.\n\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\nAcked-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "8576762ff5d109b841fcf4e7d3883e0cf794f3cf", "tree": "ad8fc56461bc29531a2b42d71c17d1db3c909263", "parents": [ "e32e28edc3d894201e15b19df627af66023aa91f" ], "author": { "name": "Russell King", "email": "rmk@dyn-67.arm.linux.org.uk", "time": "Sun Oct 30 16:33:11 2005 +0000" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Sun Oct 30 16:33:11 2005 +0000" }, "message": "[DRIVER MODEL] Add missing driver_unregister to IMX serial driver\n\nFix the IMX serial driver to unregister its driver structure\nwhen it is unloaded.\n\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\nAcked-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "d052d1beff706920e82c5d55006b08e256b5df09", "tree": "dac91b70361b405ab8e15207f514a2f3e991e93d", "parents": [ "8a212ab6b8a4ccc6f3c3d1beba5f92655c576404" ], "author": { "name": "Russell King", "email": "rmk@dyn-67.arm.linux.org.uk", "time": "Sat Oct 29 19:07:23 2005 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Sat Oct 29 19:07:23 2005 +0100" }, "message": "Create platform_device.h to contain all the platform device details.\nConvert everyone who uses platform_bus_type to include\nlinux/platform_device.h.\n\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\nAcked-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "9480e307cd88ef09ec9294c7d97ebec18e6d2221", "tree": "967e26d3a23c24dd52b114d672312c207714308c", "parents": [ "a3a3395e487abc4c1371fe319a8ecbb3913a70a4" ], "author": { "name": "Russell King", "email": "rmk@arm.linux.org.uk", "time": "Fri Oct 28 09:52:56 2005 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Oct 28 09:52:56 2005 -0700" }, "message": "[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks\n\nIn PM v1, all devices were called at SUSPEND_DISABLE level.

Here\u0027s an (untested) patch to do exactly that.\n\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "ceca629e0b4858d6b8bff260dab2e947d31aca56", "tree": "56b9a6a6dbf1674c7111dfaa255f294c895dd4e2", "parents": [ "9f693d7b149a74bac301ee47136359294cffed25" ], "author": { "name": "Sascha Hauer", "email": "sascha@saschahauer.de", "time": "Wed Oct 12 19:58:08 2005 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Wed Oct 12 19:58:08 2005 +0100" }, "message": "[ARM] 2971/1: i.MX uart handle rts irq\n\nPatch from Sascha Hauer\n\nhandle rts interrupt\n\nSigned-off-by: Giancarlo Formicuccia \u003cgiancarlo.formicuccia@gmail.com\u003e\nSigned-off-by: Sascha Hauer \u003cs.hauer@pengutronix.de\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "86371d071bc38a181984b01d323b6172a4b7bb1f", "tree": "bc0e483864c97c0b38721ba4725028aa4d77116d", "parents": [ "ce80cc14810fbd78fa70c15c7e16a0b26d462fc6" ], "author": { "name": "Sascha Hauer", "email": "sascha@saschahauer.de", "time": "Mon Oct 10 10:17:42 2005 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Mon Oct 10 10:17:42 2005 +0100" }, "message": "[ARM] 2957/1: imx UART Error handling\n\nPatch from Sascha Hauer\n\nFix error path in imx_startup.\n\nSigned-off-by: Giancarlo Formicuccia \u003cgformicuccia@atinno.com\u003e\nSigned-off-by: Sascha Hauer \u003cs.hauer@pengutronix.de\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "9f4426dde2be352aabc326539eccc726cea2d98c", "tree": "a36e6d4f5b808e74c3701572168a85e7b6403a45", "parents": [ "f0e837d9182d7903bde3ebafbd1d0d68c6d32d43" ], "author": { "name": "Vincent Sanders", "email": "vince@kyllikki.org", "time": "Sat Oct 01 22:56:34 2005 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Sat Oct 01 22:56:34 2005 +0100" }, "message": "[ARM] 2944/1: GCC 4 mx1ads serial driver compile fix\n\nPatch from Vincent Sanders\n\nWhen building the mx1ads ARM platforms the serial driver fails to compile\nwith GCC 4.01 due to extern/static ambiguity.\n\nSigned-off-by: Vincent Sanders \u003cvince@arm.linux.org.uk\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "0f302dc35412dc67035efc188b9d5c40711b4222", "tree": "57cbbe8e722e6a82bfd8bb3b8227898c54615c72", "parents": [ "b129a8ccd53f74c43e4c83c8e0031a4990040830" ], "author": { "name": "Sascha Hauer", "email": "sascha@saschahauer.de", "time": "Wed Aug 31 21:48:47 2005 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Wed Aug 31 21:48:47 2005 +0100" }, "message": "[ARM] 2866/1: add i.MX set_mctrl / get_mctrl functions\n\nPatch from Sascha Hauer\n\nThis patch adds support for setting and getting RTS / CTS via\nset_mtctrl / get_mctrl functions.\n\nSigned-off-by: Sascha Hauer \u003cs.hauer@pengutronix.de\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "b129a8ccd53f74c43e4c83c8e0031a4990040830", "tree": "4c40afd836be87166d6d014380262f1baa19694f", "parents": [ "6b39374a27eb4be7e9d82145ae270ba02ea90dc8", "194d0710e1a7fe92dcf860ddd31fded8c3103b7a" ], "author": { "name": "Russell King", "email": "rmk@dyn-67.arm.linux.org.uk", "time": "Wed Aug 31 10:12:14 2005 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Wed Aug 31 10:12:14 2005 +0100" }, "message": "[SERIAL] Clean up and fix tty transmission start/stoping\n\nThe start_tx and stop_tx methods were passed a flag to indicate\nwhether the start/stop was from the tty start/stop callbacks, and\nsome drivers used this flag to decide whether to ask the UART to\nimmediately stop transmission (where the UART supports such a\nfeature.)\n\nThere are other cases when we wish this to occur - when CTS is\nlowered, or if we change from soft to hard flow control and CTS\nis inactive.
