By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. diff --git a/MAINTAINERS b/MAINTAINERS index 0b49e978e0d6..3cfdcd451147 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -5625,9 +5625,9 @@ F: include/linux/ata.h F: include/linux/libata.h SERVER ENGINES 10Gbps iSCSI - BladeEngine 2 DRIVER -M: Jayamohan Kallickal <jayamohank@serverengines.com> +M: Jayamohan Kallickal <jayamohan.kallickal@emulex.com> L: linux-scsi@vger.kernel.org -W: http://www.serverengines.com +W: http://www.emulex.com S: Supported F: drivers/scsi/be2iscsi/ diff --git a/drivers/message/fusion/mptbase.h b/drivers/message/fusion/mptbase.h index 1735c84ff757..fe902338539b 100644 --- a/drivers/message/fusion/mptbase.h +++ b/drivers/message/fusion/mptbase.h @@ -76,8 +76,8 @@ #define COPYRIGHT "Copyright (c) 1999-2008 " MODULEAUTHOR #endif -#define MPT_LINUX_VERSION_COMMON "3.04.18" -#define MPT_LINUX_PACKAGE_NAME "@(#)mptlinux-3.04.18" +#define MPT_LINUX_VERSION_COMMON "3.04.19" +#define MPT_LINUX_PACKAGE_NAME "@(#)mptlinux-3.04.19" #define WHAT_MAGIC_STRING "@" "(" "#" ")" #define show_mptmod_ver(s,ver) \ diff --git a/drivers/message/fusion/mptscsih.c b/drivers/message/fusion/mptscsih.c index 0d9b82a44540..a1d4ee6671be 100644 --- a/drivers/message/fusion/mptscsih.c +++ b/drivers/message/fusion/mptscsih.c @@ -1415,11 +1415,8 @@ mptscsih_qcmd(struct scsi_cmnd *SCpnt, void (*done)(struct scsi_cmnd *)) dmfprintk(ioc, printk(MYIOC_s_DEBUG_FMT "qcmd: SCpnt=%p, done()=%p\n", ioc->name, SCpnt, done)); - if (ioc->taskmgmt_quiesce_io) { - dtmprintk(ioc, printk(MYIOC_s_WARN_FMT "qcmd: SCpnt=%p timeout + 60HZ\n", - ioc->name, SCpnt)); + if (ioc->taskmgmt_quiesce_io) return SCSI_MLQUEUE_HOST_BUSY; - } /* * Put together a MPT SCSI request... @@ -1773,7 +1770,6 @@ mptscsih_abort(struct scsi_cmnd * SCpnt) int scpnt_idx; int retval; VirtDevice *vdevice; - ulong sn = SCpnt->serial_number; MPT_ADAPTER *ioc; /* If we can't locate our host adapter structure, return FAILED status. @@ -1859,8 +1855,7 @@ mptscsih_abort(struct scsi_cmnd * SCpnt) vdevice->vtarget->id, vdevice->lun, ctx2abort, mptscsih_get_tm_timeout(ioc)); - if (SCPNT_TO_LOOKUP_IDX(ioc, SCpnt) == scpnt_idx && - SCpnt->serial_number == sn) { + if (SCPNT_TO_LOOKUP_IDX(ioc, SCpnt) == scpnt_idx) { dtmprintk(ioc, printk(MYIOC_s_DEBUG_FMT "task abort: command still in active list!

The command syntax is, - * - * echo 2 <where> <count> <value> > pciCfg - * - * where, 2 is the iDiag command for PCI config space write, <where> is - * the offset from the beginning of the device's PCI config space to write - * into, <count> is the size of data to write into the PCI config space, - * it will be 1 for writing a byte (8 bits), 2 for writing a word (16 bits - * or 2 bytes), or 4 for writing a dword (32 bits or 4 bytes), and <value> - * is the data to be written into the PCI config space register at the - * offset. - * - * Examples: - * To disable PCI device's interrupt assertion, - * - * 1) Read in device's PCI config space register command field <cmd>: - * - * echo 1 4 2 > pciCfg - * cat pciCfg - * - * 2) Set bit 10 (Interrupt Disable bit) in the <cmd>: - * - * <cmd> = <cmd> | (1 < 10) - * - * 3) Write the modified command back: - * - * echo 2 4 2 <cmd> > pciCfg - * - * 3. For PCI config space register set bits access, it supports a single PCI - * config space register set bits in the size of a byte (8 bits), a word - * (16 bits), or a dword (32 bits). The command syntax is, - * - * echo 3 <where> <count> <bitmask> > pciCfg - * - * where, 3 is the iDiag command for PCI config space set bits, <where> is - * the offset from the beginning of the device's PCI config space to set - * bits into, <count> is the size of the bitmask to set into the PCI config - * space, it will be 1 for setting a byte (8 bits), 2 for setting a word - * (16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4 bytes), and - * <bitmask> is the bitmask, indicating the bits to be set into the PCI - * config space register at the offset. The logic performed to the content - * of the PCI config space register, regval, is, - * - * regval |= <bitmask> - * - * 4. For PCI config space register clear bits access, it supports a single - * PCI config space register clear bits in the size of a byte (8 bits), - * a word (16 bits), or a dword (32 bits). The command syntax is, - * - * echo 4 <where> <count> <bitmask> > pciCfg - * - * where, 4 is the iDiag command for PCI config space clear bits, <where> - * is the offset from the beginning of the device's PCI config space to - * clear bits from, <count> is the size of the bitmask to set into the PCI - * config space, it will be 1 for setting a byte (8 bits), 2 for setting - * a word(16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4 - * bytes), and <bitmask> is the bitmask, indicating the bits to be cleared - * from the PCI config space register at the offset. the logic performed - * to the content of the PCI config space register, regval, is, - * - * regval &= ~<bitmask> - * - * Note, for all single register read, write, set bits, or clear bits access, - * the offset (<where>) must be aligned with the size of the data: - * - * For data size of byte (8 bits), the offset must be aligned to the byte - * boundary; for data size of word (16 bits), the offset must be aligned - * to the word boundary; while for data size of dword (32 bits), the offset - * must be aligned to the dword boundary.
