      "message": "[PATCH] remove many unneeded #includes of sched.h\n\nAfter Al Viro (finally) succeeded in removing the sched.h #include in module.h\nrecently, it makes sense again to remove other superfluous sched.h includes.\nThere are quite a lot of files which include it but don\u0027t actually need\nanything defined in there.  Presumably these includes were once needed for\nmacros that used to live in sched.h, but moved to other header files in the\ncourse of cleaning it up.\n\nTo ease the pain, this time I did not fiddle with any header files and only\nremoved #includes from .c-files, which tend to cause less trouble.\n\nCompile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,\narm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,\nallmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all\nconfigs in arch/arm/configs on arm.

      "message": "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers\n\nMaintain a per-CPU global \"struct pt_regs *\" variable which can be used instead\nof passing regs around manually through all ~1800 interrupt handlers in the\nLinux kernel.\n\nThe regs pointer is used in few places, but it potentially costs both stack\nspace and code to pass it around.  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"

      "message": "[SERIAL] IP22: fix serial console hangs\n\nThe patch below fixes serial console hangs as seen on IP22\nmachines. Typically, while booting, the machine hangs for ~1 minute\ndisplaying \"INIT: \", then the same thing happens again when init\nenters in the designated runlevel and finally the getty process on\nttyS0 hangs indefinitely (though strace\u0027ing it helps).\n\nstrace (-e raw\u003dioctl, otherwise the ioctl() translation is utterly\nbogus) reveals that getty hangs on ioctl() 0x540f which happens to be\nTCSETSW (I saw it hang on another console ioctl() but couldn\u0027t\nreproduce that one).\n\nA diff between ip22zilog and sunzilog revealed the following\ndifferences:\n 1. the channel A flag being set on up.port.flags instead of up.flags\n 2. the channel A flag being set on what is marked as being channel B\n 3. sunzilog has a call to uart_update_timeout(port, termios-\u003ec_cflag, baud);\n    at the end of sunzilog_set_termios(), which ip22zilog lacks (on\n    purpose ?)\n\nThe patch below addresses point 1 and fixes the serial console hangs\njust fine. However point 2 should be investigated by someone familiar\nwith the IP22 Zilog; it\u0027s probably OK as is but even if it is, a\ncomment in ip22zilog.c is badly needed.\n\nPoint 3 is left as an exercise for whoever feels like digging into\nip22zilog :)\n\nThese are the main obvious differences between ip22zilog and\nsunzilog. Newer versions of sunzilog (Linus\u0027s git tree as of today)\nare more close to ip22zilog as the sbus_{write,read}b have been\nchanged into simple {write,read}b, which shrinks the diff by a fair\namount.

      "message": "[PATCH] TTY layer buffering revamp\n\nThe API and code have been through various bits of initial review by\nserial driver people but they definitely need to live somewhere for a\nwhile so the unconverted drivers can get knocked into shape, existing\ndrivers that have been updated can be better tuned and bugs whacked out.\n\nThis replaces the tty flip buffers with kmalloc objects in rings. 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"
