As cpu stoppers are\nguaranteed to be available for all online cpus,\nstop_machine_create/destroy() are no longer necessary and removed.\n\nWith resource management and synchronization handled by cpu_stop, the\nnew implementation is much simpler. Asking the cpu_stop to execute\nthe stop_cpu() state machine on all online cpus with cpu hotplug\ndisabled is enough.\n\nstop_machine itself doesn\u0027t need to manage any global resources\nanymore, so all per-instance information is rolled into struct\nstop_machine_data and the mutex and all static data variables are\nremoved.\n\nThe previous implementation created and destroyed RT workqueues as\nnecessary which made stop_machine() calls highly expensive on very\nlarge machines. According to Dimitri Sivanich, preventing the dynamic\ncreation/destruction makes booting faster more than twice on very\nlarge machines. cpu_stop resources are preallocated for all online\ncpus and should have the same effect.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Dimitri Sivanich \u003csivanich@sgi.com\u003e\n" }, { "commit": "1142d810298e694754498dbb4983fcb6cb7fd884", "tree": "8c5d23b76f129e23d9d967182aa434795e44af5c", "parents": [ "99bd5e2f245d8cd17d040c82d40becdb3efd9b69" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Thu May 06 18:49:20 2010 +0200" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Thu May 06 18:49:20 2010 +0200" }, "message": "cpu_stop: implement stop_cpu[s]()\n\nImplement a simplistic per-cpu maximum priority cpu monopolization\nmechanism.

Based on the\ntests in the bug reports below, Windows apparently uses [_MIN to _MAX].\n\nPer spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location\ndescriptors, \"_LEN must be (_MAX - _MIN + 1)\", and when that\u0027s true, it\ndoesn\u0027t matter which way we compute the end. But of course, there are\nBIOSes that don\u0027t follow this rule, and we\u0027re better off if Linux handles\nthose exceptions the same way as Windows.\n\nThis patch makes Linux use [_MIN to _MAX], as Windows seems to do. This\neffectively reverts d558b483d5 and 03db42adfe and replaces them with\nsimpler code.\n\n https://bugzilla.kernel.org/show_bug.cgi?id\u003d14337 (round)\n https://bugzilla.kernel.org/show_bug.cgi?id\u003d15480 (truncate)\n\nSigned-off-by: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "3fb938b2a8bdbcf6086192d90fb7c73425e41fb9", "tree": "3b273692ee6a34c603f83a645b29573c404ffc97", "parents": [ "970b06485ffee36aa3549dfe4c6b2a2c2118354d", "83bf6f11e82eba8533f8dbd241b2c2825e42ae5d" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 28 07:58:36 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 28 07:58:36 2010 -0700" }, "message": "Merge branch \u0027urgent\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6\n\n* \u0027urgent\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6:\n pcmcia: fix matching rules for pseudo-multi-function cards\n pcmcia: pcmcia_dev_present bugfix\n" }, { "commit": "970b06485ffee36aa3549dfe4c6b2a2c2118354d", "tree": "1b0f6f4182e73d19071addf8a209e5fb58483d08", "parents": [ "696e65c3606aa3f587eeb181766baf49ea750cfc", "33f60e9640b2f60dde6735293d4aa5ecc5b1d5d5" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 28 07:56:05 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 28 07:56:05 2010 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block\n\n* \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block:\n coda: move backing-dev.h kernel include inside __KERNEL__\n mtd: ensure that bdi entries are properly initialized and registered\n Move mtd_bdi_*mappable to mtdcore.c\n btrfs: convert to using bdi_setup_and_register()\n Catch filesystems lacking s_bdi\n drbd: Terminate a connection early if sending the protocol fails\n drbd: fix memory leak\n Fix JFFS2 sync silent failure\n smbfs: add bdi backing to mount session\n ncpfs: add bdi backing to mount session\n exofs: add bdi backing to mount session\n ecryptfs: add bdi backing to mount session\n coda: add bdi backing to mount session\n cifs: add bdi backing to mount session\n afs: add bdi backing to mount session.\n 9p: add bdi backing to mount session\n bdi: add helper function for doing init and register of a bdi for a file system\n block: ensure jiffies wrap is handled correctly in blk_rq_timed_out_timer\n" }, { "commit": "696e65c3606aa3f587eeb181766baf49ea750cfc", "tree": "1975089f9faa51eb40f6680b3dd7394cd57b8eed", "parents": [ "1600f9def09de07c5dbeb539e978fa73880690dd", "d8d8b63b6dc413696ade040e52173c068df11702" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 28 07:55:35 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 28 07:55:35 2010 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/wim/linux-2.6-watchdog\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/wim/linux-2.6-watchdog:\n watchdog: booke_wdt: fix build -

Improved error handling.\n2. Added the missing timeout arguments to usb_control_msg().\n\nThe following is a new Linux driver which exposes certain models of Sierra\nWireless modems to the operating system as Network Interface Cards (NICs).\n\nThis driver requires a version of the sierra.c driver which supports\nblacklisting to work properly. The blacklist in sierra.c rejects the interfaces\nclaimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts\n(i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.\nThe version of sierra.c which supports blacklisting is\navailable from the sierra wireless knowledge base page for older kernels. It is\nalso available in Linux kernel starting from version 2.6.31.\n\nThis driver works with all Sierra Wireless devices configured with PID\u003d68A3\nlike USB305, USB306 provided the corresponding firmware version is I2.0\n(for USB305) or M3.0 (for USB306) and later.\nThis driver will not work with earlier firmware versions than the ones shown\nabove. In this case the driver will issue an error message indicating\nincompatibility and will not serve the device\u0027s USB-to-WWAN interface.\n\nSierra_net.c sits atop a pre-existing Linux driver called usbnet.c.\nA series of hook functions are provided in sierra_net.c which are called by\nusbnet.c in response to a particular condition such as receipt or transmission\nof a data packet. As such, usbnet.c does most of the work of making\na modem appear to the system as a network device and for properly exchanging\ntraffic between the USB subsystem and the Network card interface.\nSierra_net.c is concerned with managing the data exchanged between the\nUSB-to-WWAN interface and the upper layers of the operating system.\n\nSigned-off-by: Elina Pasheva \u003cepasheva@sierrawireless.com\u003e\nSigned-off-by: Rory Filer \u003crfiler@sierrawireless.com\u003e\nSigned-off-by: David S.
