registration\n\nThis patch (as1522) adds two new routines to the usb-serial core, for\nregistering and unregistering serial drivers. Instead of registering\nthe usb_driver and usb_serial_drivers separately, with error checking\nfor each one, the drivers can all be registered and unregistered by a\nsingle function call. This reduces duplicated code.\n\nMore importantly, the new core routines change the order in which the\ndrivers are registered. Currently the usb-serial drivers are all\nregistered first and the usb_driver is done last, which leaves a\nwindow for problems. A udev script may quickly add a new dynamic-ID\nfor a usb-serial driver, causing the corresponding usb_driver to be\nprobed. If the usb_driver hasn\u0027t been registered yet then an oops\nwill occur.\n\nThe new routine prevents such problems by registering the usb_driver\nfirst. To insure that it gets probed properly for already-attached\nserial devices, we call driver_attach() after all the usb-serial\ndrivers have been registered.\n\nAlong with adding the new routines, the patch modifies the \"generic\"\nserial driver to use them. Further patches will similarly modify all\nthe other in-tree USB serial drivers.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: Greg Kroah-Hartman

CR0 accesses\n are quite slow and expensive, don\u0027t flip the bit back and forth for\n no good reason.\n\n - Make sure that the same model works for both x86-32 and x86-64, so\n that there are no gratuitous differences between the two due to the\n way they save and restore segment state differently due to\n architectural differences that really don\u0027t matter to the FPU state.\n\n - Avoid exposing the \"preload\" state to the context switch routines,\n and in particular allow the concept of lazy state restore: if nothing\n else has used the FPU in the meantime, and the process is still on\n the same CPU, we can avoid restoring state from memory entirely, just\n re-expose the state that is still in the FPU unit.\n\n That optimized lazy restore isn\u0027t actually implemented here, but the\n infrastructure is set up for it. Of course, older CPU\u0027s that use\n \u0027fnsave\u0027 to save the state cannot take advantage of this, since the\n state saving also trashes the state.\n\nIn other words, there is now an actual _design_ to the FPU state saving,\nrather than just random historical baggage.

The\n change to TS_USEDFPU would be overwritten by the final store.\n\n In practice, this seldom happened, though, because the \u0027status\u0027 field\n was seldom used more than once, so gcc would generally tend to\n generate code that used a read-modify-write instruction and thus\n happened to avoid this problem - RMW instructions are naturally low\n fat and preemption-safe.\n\n - On x86-32, the current_thread_info() pointer would, during interrupts\n and softirqs, point to a *copy* of the real thread_info, because\n x86-32 uses %esp to calculate the thread_info address, and thus the\n separate irq (and softirq) stacks would cause these kinds of odd\n thread_info copy aliases.\n\n This is normally not a problem, since interrupts aren\u0027t supposed to\n look at thread information anyway (what thread is running at\n interrupt time really isn\u0027t very well-defined), but it confused the\n heck out of irq_fpu_usable() and the code that tried to squirrel\n away the FPU state.\n\n (It also caused untold confusion for us poor kernel developers).\n\nIt also turns out that using \u0027task_struct\u0027 is actually much more natural\nfor most of the call sites that care about the FPU state, since they\ntend to work with the task struct for other reasons anyway (ie\nscheduling).

With preemption this can\nhappen even without the page fault - but because of the user access, we\ncannot just disable preemption around the save/restore instruction.\n\nThere are various ways to solve this, including using the\n\"enable/disable_page_fault()\" helpers to not allow page faults at all\nduring the sequence, and fall back to copying things by hand without the\nuse of the native FP state save/restore instructions.\n\nHowever, the simplest thing to do is to just allow the #NM from kernel\nspace, but fix the race in setting and clearing CR0.TS that this all\nexposed: the TS bit changes and the TS_USEDFPU bit absolutely have to be\natomic wrt scheduling, so while the actual state save/restore can be\ninterrupted and restarted, the act of actually clearing/setting CR0.TS\nand the TS_USEDFPU bit together must not.\n\nInstead of just adding random \"preempt_disable/enable()\" calls to what\nis already excessively ugly code, this introduces some helper functions\nthat mostly mirror the \"kernel_fpu_begin/end()\" functionality, just for\nthe user state instead.\n\nThose helper functions should probably eventually replace the other\nad-hoc CR0.TS and TS_USEDFPU tests too, but I\u0027ll need to think about it\nsome more: the task switching functionality in particular needs to\nexpose the difference between the \u0027prev\u0027 and \u0027next\u0027 threads, while

This could take seconds or longer.\n\nWith the patch applied I get the expected number of samples:\n\n SAMPLE events: 9948\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: \u003cstable@kernel.org\u003e\n" }, { "commit": "64f8c13561fbd2f1a8b4a8975b2aee73b561093e", "tree": "96a397f590a064de9987ff1144a293fc2bf3602f", "parents": [ "54321242afe6fcf8b7e589bc21ecf832bc5a206a" ], "author": { "name": "majianpeng", "email": "majianpeng@gmail.com", "time": "Fri Feb 03 14:35:59 2012 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Feb 16 16:15:12 2012 +1100" }, "message": "powerpc/adb: Use set_current_state()\n\nSigned-off-by: majianpeng \u003cmajianpeng@gmail.com\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "54321242afe6fcf8b7e589bc21ecf832bc5a206a", "tree": "dfc1d3bd73cd1c28421e27bbbbcad60368a69907", "parents": [ "a1a1d1bfc9be2a5ea8cce78ebd0f17c79489f053" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Feb 13 20:42:18 2012 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Feb 16 16:15:10 2012 +1100" }, "message": "powerpc: Disable interrupts early in Program Check\n\nProgram Check exceptions are the result of WARNs, BUGs, some\ntype of breakpoints, kprobe, and other illegal instructions.\n\nWe want interrupts (and thus preemption) to remain disabled\nwhile doing the initial stage of testing the reason and\nbranching off to a debugger or kprobe, so we are still on\nthe original CPU which makes debugging easier in various cases.\n\nThis is how the code was intended, hence the local_irq_enable()\nright in the middle of program_check_exception().\n\nHowever, the assembly exception prologue for that exception was\nincorrectly marked as enabling interrupts, which defeats that\n(and records a redundant enable with lockdep).\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "a1a1d1bfc9be2a5ea8cce78ebd0f17c79489f053", "tree": "78a3d679a281096d34c8437e38547d3fcb0e3b2c", "parents": [ "13635dfdc6aa8d2890e02dc441decfcb4ae63e14" ], "author": { "name": "Stephen Rothwell", "email": "sfr@canb.auug.org.au", "time": "Tue Feb 14 16:31:09 2012 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Feb 16 16:15:08 2012 +1100" }, "message": "powerpc: Remove legacy iSeries from ppc64_defconfig\n\nSince we are heading towards removing the Legacy iSeries platform, start\nby no longer building it for ppc64_defconfig.\n\nSigned-off-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "13635dfdc6aa8d2890e02dc441decfcb4ae63e14", "tree": "817d08d8b06183bccb28e0c829213f1fceab3b3a", "parents": [ "40c8cefaaf12734327db7199a56e60058d98e7b6" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Feb 14 18:22:20 2012 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Feb 16 16:15:03 2012 +1100" }, "message": "powerpc/fsl/pci: Fix PCIe fixup regression\n\nUpstream changes to the way PHB resources are registered\nbroke the resource fixup for FSL boards.\n\nWe can no longer rely on the resource pointer array for the PHB\u0027s\npci_bus structure, so let\u0027s leave it alone and go straight for\nthe PHB resources instead.
