The code can patch both SMP-\u003eUP and UP-\u003eSMP.\nThe UP-\u003eSMP case is useful for CPU hotplug.\n\nWith CONFIG_CPU_HOTPLUG enabled the code switches to UP at boot time and\nwhen the number of CPUs goes down to 1, and switches to SMP when the number\nof CPUs goes up to 2.\n\nWithout CONFIG_CPU_HOTPLUG or on non-SMP-capable systems the code is\npatched once at boot time (if needed) and the tables are released\nafterwards.\n\nThe changes in detail:\n\n * The current alternatives bits are moved to a separate file,\n the SMP alternatives code is added there.\n\n * The patch adds some new elf sections to the kernel:\n .smp_altinstructions\n\tlike .altinstructions, also contains a list\n\tof alt_instr structs.\n .smp_altinstr_replacement\n\tlike .altinstr_replacement, but also has some space to\n\tsave original instruction before replaving it.\n .smp_locks\n\tlist of pointers to lock prefixes which can be nop\u0027ed\n\tout on UP.\n The first two are used to replace more complex instruction\n sequences such as spinlocks and semaphores. It would be possible\n to deal with the lock prefixes with that as well, but by handling\n them as special case the table sizes become much smaller.\n\n * The sections are page-aligned and padded up to page size, so they\n can be free if they are not needed.\n\n * Splitted the code to release init pages to a separate function and\n use it to release the elf sections if they are unused.\n\nSigned-off-by: Gerd Hoffmann \u003ckraxel@suse.de\u003e\nSigned-off-by: Chuck Ebbert \u003c76306.1226@compuserve.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "7835e98b2e3c66dba79cb0ff8ebb90a2fe030c29", "tree": "405a96eade34845dabe2f125b6c5eb095846869d", "parents": [ "70dc991d66cac40fdb07346dba2b5d862d732c34" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Wed Mar 22 00:08:40 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Mar 22 07:54:02 2006 -0800" }, "message": "[PATCH] remove set_page_count() outside mm/\n\nset_page_count usage outside mm/ is limited to setting the refcount to 1.\nRemove set_page_count from outside mm/, and replace those users with\ninit_page_count() and set_page_refcounted().\n\nThis allows more debug checking, and tighter control on how code is allowed\nto play around with page-\u003e_count.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "70dc991d66cac40fdb07346dba2b5d862d732c34", "tree": "53ba8de1ae2d49f7479391e82794e35f14c0f7f7", "parents": [ "84097518d1ecd2330f9488e4c2d09953a3340e74" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Wed Mar 22 00:08:35 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Mar 22 07:54:01 2006 -0800" }, "message": "[PATCH] remove set_page_count(page, 0) users (outside mm)\n\nA couple of places set_page_count(page, 1) that don\u0027t need to.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fe1db50c7222c67466e41241bc7ef17b469bcf1d", "tree": "1956b61473d8e9cc8a1a0849e75a728b1395f902", "parents": [ "f462e8f913bdc7a28ce55508d0c045a0c445b157" ], "author": { "name": "Paolo \u0027Blaisorblade\u0027 Giarrusso", "email": "blaisorblade@yahoo.it", "time": "Fri Feb 24 13:03:58 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Feb 24 14:31:37 2006 -0800" }, "message": "[PATCH] uml: tidying COW code\n\nImprove (especially for coherence) some prototypes, and return code of\ninit_cow_file in error case - for a short write return -EINVAL, otherwise\nreturn the error we got!\n\nSigned-off-by: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nAcked-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f462e8f913bdc7a28ce55508d0c045a0c445b157", "tree": "ce584e748f632d90307d3c2cd62294f3b209c903", "parents": [ "dc1561ac019ff7b6f75c5175abd2ec65c8dbd581" ], "author": { "name": "Paolo \u0027Blaisorblade\u0027 Giarrusso", "email": "blaisorblade@yahoo.it", "time": "Fri Feb 24 13:03:57 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Feb 24 14:31:37 2006 -0800" }, "message": "[PATCH] uml: better error reporting for read_output\n\nDo precise error handling: print precise error messages, distinguishing short\nreads and read errors.

Interrupt enabling and disabling no\nlonger map to sigprocmask. Rather, a flag is set indicating whether\ninterrupts may be handled. If a signal comes in and interrupts are marked as\nOK, then it is handled normally. If interrupts are marked as off, then the\nsignal handler simply returns after noting that a signal needs handling. When\ninterrupts are enabled later on, this pending signals flag is checked, and the\nIRQ handlers are called at that point.\n\nThe point of this is to reduce the cost of local_irq_save et al, since they\nare very much more common than the signals that they are enabling and\ndisabling. Soft interrupts produce a speed-up of ~25% on a kernel build.\n\nSubtleties -\n\n UML uses sigsetjmp/siglongjmp to switch contexts. sigsetjmp has been\n wrapped in a save_flags-like macro which remembers the interrupt state at\n setjmp time, and restores it when it is longjmp-ed back to.\n\n The enable_signals function has to loop because the IRQ handler\n disables interrupts before returning. enable_signals has to return with\n signals enabled, and signals may come in between the disabling and the\n return to enable_signals. So, it loops for as long as there are pending\n signals, ensuring that signals are enabled when it finally returns, and\n that there are no pending signals that need to be dealt with.\n\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "09ee011eb322c2072ec184a88763c250a5485d8b", "tree": "ea13731ab3d7fe143b27b0f060956b3cec0f727a", "parents": [ "abaf69773d8dda98b917d94c07757f6520da7bec" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Wed Jan 18 17:42:48 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Jan 18 19:20:20 2006 -0800" }, "message": "[PATCH] uml: eliminate some globals\n\nStop using global variables to hold the file descriptor and offset used to map\nthe skas0 stubs.

So, a\nsymlink is made from arch/um/include/kernel-offsets.h to\ninclude/asm-um/asm-offsets.h.\n\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "33f0f88f1c51ae5c2d593d26960c760ea154c2e2", "tree": "f53a38cf49406863f079d74d0e8f91b276f7c1a9", "parents": [ "6ed80991a2dce4afc113be35089c564d62fa1f11" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Mon Jan 09 20:54:13 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jan 10 08:01:59 2006 -0800" }, "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" }, { "commit": "becf8b5d00f4b47e847f98322cdaf8cd16243861", "tree": "152ba7583324c64d34ecc70d5401957ca7225761", "parents": [ "97735f25d2ba898ec5e13746451525580631c834" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Mon Jan 09 20:52:38 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jan 10 08:01:39 2006 -0800" }, "message": "[PATCH] hrtimer: convert posix timers completely\n\n- convert posix-timers.c to use hrtimers\n\n- remove the now obsolete abslist code\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "e585e47031751f4e393e10ffd922885508b958dd", "tree": "08a641dab000aacb25c6b7331c32271e4109535f", "parents": [ "22c4e3084eb8b88288a622a57d8b35c450a439f2" ], "author": { "name": "Matt Mackall", "email": "mpm@selenic.com", "time": "Sun Jan 08 01:05:24 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:14:11 2006 -0800" }, "message": "[PATCH] tiny: Make *[ug]id16 support optional\n\nConfigurable 16-bit UID and friends support\n\nThis allows turning off the legacy 16 bit UID interfaces on embedded platforms.\n\n text data bss dec hex filename\n3330172 529036 190556 4049764 3dcb64 vmlinux-baseline\n3328268 529040 190556 4047864 3dc3f8 vmlinux\n\nFrom: Adrian Bunk \u003cbunk@stusta.de\u003e\n\n UID16 was accidentially disabled for !EMBEDDED.\n\nSigned-off-by: Matt Mackall \u003cmpm@selenic.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": "5e38291d80086f6972f471c7caffa03184de0bf0", "tree": "563a6aaac4f8c15f448080a3cec738821fa14a0b", "parents": [ "87ba81dba431232548ce29d5d224115d0c2355ac" ], "author": { "name": "Eric W.

It is expected that /sbin/halt -p works exactly like\n/sbin/halt, when the kernel does not implement power off functionality.\n\nThe kernel can do a lot of work in the reboot notifiers and in\ndevice_shutdown before we even get to machine_power_off. Some of that\nshutdown is not safe if you are leaving the power on, and it definitely\ngets in the way of using sysrq or pressing ctrl-alt-del. Since the\nshutdown happens in generic code there is no way to fix this in\narchitecture specific code :(\n\nSome machines are kernel oopsing today because of this.\n\nThe simple solution is to turn LINUX_REBOOT_CMD_POWER_OFF into\nLINUX_REBOOT_CMD_HALT if power_off functionality is not implemented.\n\nThis has the unfortunate side effect of disabling the power off\nfunctionality on architectures that leave pm_power_off to null and still\nimplement something in machine_power_off. And it will break the build on\nsome architectures that don\u0027t have a pm_power_off variable at all.\n\nOn both counts I say tough.\n\nFor architectures like alpha that don\u0027t implement the pm_power_off variable\npm_power_off is declared in linux/pm.h and it is a generic part of our\npower management code, and all architectures should implement it.\n\nFor architectures like parisc that have a default power off method in\nmachine_power_off if pm_power_off is not implemented or fails. It is easy\nenough to set the pm_power_off variable. And nothing bad happens there,\nthe machines just stop powering off.\n\nThe current semantics are impossible without a flag at the top level so we\ncan avoid the problem code if a power off is not implemented. pm_power_off\nis as good a flag as any with the bonus that it works without modification\non at least x86, x86_64, powerpc, and ppc today.\n\nAndrew can you pick this up and put this in the mm tree. Kernels that\ndon\u0027t compile or don\u0027t power off seem saner than kernels that oops or\npanic.

The intent is to make it obvious\nthat an IRQ can\u0027t exist without an open file descriptor.\n\nchan_enable will now open the channel, and when both opening and IRQ\nregistration are desired, this should be used. Opening only is done for the\ninitial console, so that interface still needs to exist.\n\nThe free_irqs_later interface is now gone. It was intended to avoid freeing\nan IRQ while it was being processed. It did this, but it didn\u0027t eliminate the\npossiblity of free_irq being called from an interrupt, which is bad. In its\nplace is a list of irqs to be freed, which is processed by the signal handler\njust before exiting. close_one_chan now disables irqs.\n\nWhen a host device disappears, it is just closed, and that disables IRQs.\n\nThe device id registered with the IRQ is now the chan structure, not the tty.\nThis is because the interrupt arrives on a descriptor associated with the\nchannel. This caused equivalent changes in the arguments to line_timer_cb.\nline_disable is gone since it is not used any more.\n\nThe count field in the line structure is gone. tty-\u003ecount is used instead.\n\nThe complicated logic in sigio_handler with freeing IRQs when necessary and\nmaking sure its idea of the next irq is correct is now much simpler.

Because we use syscall6 to remap the stack, the\nold contents of the stack (and the former value of ebp) are no longer\navailable. Some versions of gcc make from a real local, accessed through ebp,\ndespite my efforts to make it obvious that references to from are really\nconstants. This patch attempts to make it even more obvious by eliminating\nfrom and using a macro to access the stub\u0027s data explicitly with constants.\n\nMy original thinking on this was to replace syscall6 with a remap_stack\ninterface which saved ebp someplace and restored it afterwards. The problem\nis that there are no registers to put it in, except for esp. That could work,\nsince we can store a constant in esp after the mmap because we just replaced\nthe stack. However, this approach seems a tad cleaner.\n\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ba260e23efbabcff975f60401475c2bdd693f872", "tree": "61b78237e116abd22d15b4886c0e08f6bc63d243", "parents": [ "7a590611c0f1e1302c58fdfdc958f2d6bdddd78a" ], "author": { "name": "Paolo \u0027Blaisorblade\u0027 Giarrusso", "email": "blaisorblade@yahoo.it", "time": "Sun Nov 13 16:07:14 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Nov 13 18:14:15 2005 -0800" }, "message": "[PATCH] uml: fix daemon transport exit path bug\n\nFix some exit path bugs in the daemon driver.\n\nSigned-off-by: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nAcked-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ], "next": "7a590611c0f1e1302c58fdfdc958f2d6bdddd78a" }
