2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

Merge common irq mapping code between PowerPC and Microblaze. This patch merges of_irq_find_parent(), of_irq_map_raw() and of_irq_map_one(). The functions are dependent on one another, so all three are merged in a single patch. Other than cosmetic difference (ie. DBG() vs. pr_debug()), the implementations are identical. of_irq_to_resource() is also merged, but in this case the implementations are different. This patch drops the microblaze version and uses the powerpc implementation unchanged. The microblaze version essentially open-coded irq_of_parse_and_map() which it does not need to do. Therefore the powerpc version is safe to adopt.

2008-12-01powerpc: Fix IRQ assignment for some PCIe devicesAdhemerval Zanella
Currently, some PCIe devices on POWER6 machines do not get interrupts assigned correctly. The problem is that OF doesn't create an "interrupt" property for them. The fix is for of_irq_map_pci to fall back to using the value in the PCI interrupt-pin register in config space, as we do when there is no OF device-tree node for the device. I have verified that this works fine with a pair of Squib-E SAS adapter on a P6-570. Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-07-22powerpc: Fix OF parsing of 64 bits PCI addressesBenjamin Herrenschmidt
The OF parsing code for PCI addresses isn't always treating properly the address space indication 0b11 (ie. 0x3) as meaning 64 bits memory space. This means that it fails to parse addresses for PCI BARs that have this encoding set by the firmware, which happens on some SLOF versions and breaks offb palette handling on Powerstation.

2007-07-26Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()"Paul Mackerras
This reverts commit fd6e9d3945ee122eb513ada8b17296d243c1ce5e. Having #size-cells == 0 in a node indicates that things under the node aren't directly accessible, and therefore we shouldn't try to translate addresses for devices under the node into CPU physical addresses. Some drivers, such as the nvram driver for powermacs, rely on of_address_to_resource failing if they are called for a node representing a device whose resources aren't directly accessible by the CPU. These drivers were broken by commit fd6e9d39, resulting in the "Lombard" powerbook hanging early in the boot process. Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-12-20[POWERPC] Workaround oldworld OF bug with IRQs & P2P bridgesBenjamin Herrenschmidt
On some oldworld PowerMacs, OF doesn't assign interrupts properly beyond P2P bridges. Fortunately, the fix is easy as all those machines just wire all IRQ lines together to one IRQ which is assigned to the bridge itself. We already have a special function for parsing Apple OldWorld interrupts which are special, so let's add to it the ability to walk up the PCI tree to find interrupts.

2006-10-06[POWERPC] Don't get PCI IRQ from OF for devices with no IRQBenjamin Herrenschmidt
This patch adds checking of the PCI_INTERRUPT_PIN register before using standard OF parsing to retreive PCI interrupts. The reason is that some PCI devices may have no PCI interrupt, though they may have interrupts attached via other means. In this case, we shall not use irq->pdev, but device-specific code can later retreive those interrupts instead. Without that patch, Maple and derivatives don't get the right interrupt for the second IDE channel as the linux IDE code fallsback to the PCI irq instead of trying to use the legacy ones for the on-board controller (which has no PCI_INTERRUPT_PIN). Having no PCI IRQ assign to it (as it doesn't request any) fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

setup_peg2 must do some refcounting. of_get_pci_address may need to drop the node Pegasos l2cr : L2 cache was not active, activating PCI bus 0 controlled by pci at 80000000 Badness in kref_get at /home/olaf/kernel/olh/ppc64/linux-2.6.16-rc2-olh/lib/kref.c:32 Call Trace: [C037BD00] [C0007934] show_stack+0x5c/0x184 (unreliable) [C037BD30] [C000E068] program_check_exception+0x184/0x584 [C037BD90] [C000F5F0] ret_from_except_full+0x0/0x4c --- Exception: 700 at kref_get+0xc/0x24 LR = of_node_get+0x24/0x3c [C037BE50] [C004FD94] __pte_alloc_kernel+0x64/0x80 (unreliable) [C037BE70] [C000CA18] of_get_parent+0x34/0x58 [C037BE90] [C0009B18] of_get_address+0x24/0x174 [C037BED0] [C000A108] of_address_to_resource+0x24/0x68 [C037BF00] [C038B128] chrp_find_bridges+0x114/0x470 [C037BF90] [C038AE48] chrp_setup_arch+0x1fc/0x32c [C037BFB0] [C03849B0] setup_arch+0x144/0x188 [C037BFD0] [C037C45C] start_kernel+0x34/0x1a8 [C037BFF0] [000037A0] 0x37a0 Badness in kref_get at /home/olaf/kernel/olh/ppc64/linux-2.6.16-rc2-olh/lib/kref.c:32 Call Trace: [C037BC90] [C0007934] show_stack+0x5c/0x184 (unreliable) [C037BCC0] [C000E068] program_check_exception+0x184/0x584 [C037BD20] [C000F5F0] ret_from_except_full+0x0/0x4c --- Exception: 700 at kref_get+0xc/0x24 LR = of_node_get+0x24/0x3c [C037BDE0] [00000000] 0x0 (unreliable) [C037BE00] [C000CA18] of_get_parent+0x34/0x58 [C037BE20] [C0009CE8] of_translate_address+0x2c/0x2fc [C037BEA0] [C0009FE8] __of_address_to_resource+0x30/0xc4 [C037BED0] [C000A130] of_address_to_resource+0x4c/0x68 [C037BF00] [C038B128] chrp_find_bridges+0x114/0x470 [C037BF90] [C038AE48] chrp_setup_arch+0x1fc/0x32c [C037BFB0] [C03849B0] setup_arch+0x144/0x188 [C037BFD0] [C037C45C] start_kernel+0x34/0x1a8 [C037BFF0] [000037A0] 0x37a0 PCI bus 0 controlled by pci at c0000000 Top of RAM: 0x10000000, Total RAM: 0x10000000 Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-14[PATCH] powerpc: Recognize /chaos bridge on old pmacs as PCIPaul Mackerras
The first generation of PCI powermacs had a host bridge called /chaos which was for all intents and purposes a PCI host bridge, but has a device_type of "vci" in the device tree (presumably it's not really PCI at the hardware level or something). The OF parsing stuff in arch/powerpc/kernel/prom_parse.c currently doesn't recognize it as a PCI bridge, which means that controlfb.c can't get its device addresses. This makes prom_parse.c recognize a device_type of "vci" as indicating a PCI host bridge. With this, controlfb works again.

2006-01-09[PATCH] powerpc: pci_address_to_pio fixBenjamin Herrenschmidt
This fixes pci_address_to_pio() to return an unsigned long (to be safe) and fixes a bug in the implementation that caused it to return a bogus IO port number Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] powerpc: Update OF address parsersBenjamin Herrenschmidt
This updates the OF address parsers to return the IO flags indicating the type of address obtained. It also adds a PCI call for converting physical addresses that hit IO space into into IO tokens, and add routines that return the translated addresses into struct resource Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] powerpc: udbg updatesBenjamin Herrenschmidt
The udbg low level io layer has an issue with udbg_getc() returning a char (unsigned on ppc) instead of an int, thus the -1 if you had no available input device could end up turned into 0xff, filling your display with bogus characters. This fixes it, along with adding a little blob to xmon to do a delay before exiting when getting an EOF and fixing the detection of ADB keyboards in udbg_adb.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] powerpc: Add OF address parsing code (#2)Benjamin Herrenschmidt
Parsing addresses extracted from Open Firmware isn't a simple matter. We have various bits of code that try to do it in various place, including some heuristics in prom.c that pre-parse addresses at boot and fill device-nodes "addrs", but those are dodgy at best and I want to deprecate them. So this patch introduces a new set of routines that should be capable of parsing most types of addresses and translating them into CPU physical addresses. It currently works for things on PCI busses and ISA busses and should work on "standard" busses like the root bus or the MacIO bus that don't put funky flags in addresses. If you have other bus types that do use funky flags, you'll have to add new bus type translators, which is fairly easy.
