License cleanup: add SPDX GPL-2.0 license identifier to files with no license
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.

x86/platform/intel-mid: Make IRQ allocation a bit more flexible
In the future we would use dynamic allocation for IRQ which brings non-1:1 mapping for IOAPIC domain. Thus, we need to respect return value of mp_map_gsi_to_irq() and assign it back to the device structure. Besides that we need to read GSI from interrupt pin register to avoid cases when some drivers will try to initialize PCI device twice in a row which will call pcibios_enable_irq() twice as well. serial 0000:00:04.1: Mapped GSI28 to IRQ5 serial 0000:00:04.2: Mapped GSI29 to IRQ5 serial 0000:00:04.3: Mapped GSI54 to IRQ5 8250_mid 0000:00:04.1: Mapped GSI28 to IRQ5 8250_mid 0000:00:04.2: Mapped GSI29 to IRQ6 8250_mid 0000:00:04.3: Mapped GSI54 to IRQ7 Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Cc: Bjorn Helgaas <bhelgaas@google.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-pci@vger.kernel.org Link: http://lkml.kernel.org/r/20170724173402.12939-1-andriy.shevchenko@linux.intel.com Signed-off-by: Ingo Molnar <mingo@kernel.org> |

This is the first pull request for the new dma-mapping subsystem
In this new subsystem we'll try to properly maintain all the generic
code related to dma-mapping, and will further consolidate arch code
into common helpers.
This pull request contains:
- removal of the DMA_ERROR_CODE macro, replacing it with calls
to ->mapping_error so that the dma_map_ops instances are
more self contained and can be shared across architectures (me)
- removal of the ->set_dma_mask method, which duplicates the
->dma_capable one in terms of functionality, but requires more
duplicate code.
- various updates for the coherent dma pool and related arm code
(Vladimir)
- various smaller cleanups (me)

x86/PCI: Avoid AMD SB7xx EHCI USB wakeup defect
On an AMD Carrizo laptop, when EHCI runtime PM is enabled, EHCI ports do not assert PME# for device plug/unplug events while in D3. As Alan Stern points out [1], the PME signal is not enabled when controller is in D3, therefore it's not being woken up when new devices get plugged in. Testing shows PME signal works when the EHCI power state is D2. Clear the PCI_PM_CAP_PME_D3 and PCI_PM_CAP_PME_D3cold bits in dev->pme_support to indicate the device will not assert PME# from those states.

PCI: Work around poweroff & suspend-to-RAM issue on Macbook Pro 11
Neither soft poweroff (transition to ACPI power state S5) nor
suspend-to-RAM (transition to state S3) works on the Macbook Pro 11,4 and
11,5.
The problem is related to the [mem 0x7fa00000-0x7fbfffff] space. When we
use that space, e.g., by assigning it to the 00:1c.0 Root Port, the ACPI
Power Management 1 Control Register (PM1_CNT) at [io 0x1804] doesn't work
anymore.
Linux does a soft poweroff (transition to S5) by writing to PM1_CNT. The
theory about why this doesn't work is:
- The write to PM1_CNT causes an SMI
- The BIOS SMI handler depends on something in
[mem 0x7fa00000-0x7fbfffff]
- When Linux assigns [mem 0x7fa00000-0x7fbfffff] to the 00:1c.0 Port, it
covers up whatever the SMI handler uses, so the SMI handler no longer
works correctly
Reserve the [mem 0x7fa00000-0x7fbfffff] space so we don't assign it to
anything.
This is voodoo programming, since we don't know what the real conflict is,
but we've failed to find the root cause.

x86/PCI/ce4100: Properly lock accessor functions
x86 wants to get rid of the global pci_lock protecting the config space accessors so ECAM mode can operate completely lockless, but the CE4100 PCI code relies on that to protect the simulation registers. Restructure the code so it uses the x86 specific pci_config_lock to serialize the inner workings of the CE4100 PCI magic. That allows to remove the global locking via pci_lock later.

This is a tree wide change and has been kept separate for that reason.

x86/boot/e820: Prefix the E820_* type names with "E820_TYPE_"
So there's a number of constants that start with "E820" but which are not types - these create a confusing mixture when seen together with 'enum e820_type' values: E820MAP E820NR E820_X_MAX E820MAX To better differentiate the 'enum e820_type' values prefix them with E820_TYPE_.

x86/boot/e820: Remove spurious asm/e820/api.h inclusions
A commonly used lowlevel x86 header, asm/pgtable.h, includes asm/e820/api.h spuriously, without making direct use of it. Removing it is not simple: over the years various .c code learned to rely on this indirect inclusion. Remove the unnecessary include - this should speed up the kernel build a bit, as a large header is not included anymore in totally unrelated code.

x86/PCI: Ignore _CRS on Supermicro X8DTH-i/6/iF/6F
Martin reported that the Supermicro X8DTH-i/6/iF/6F advertises incorrect host bridge windows via _CRS: pci_root PNP0A08:00: host bridge window [io 0xf000-0xffff] pci_root PNP0A08:01: host bridge window [io 0xf000-0xffff] Both bridges advertise the 0xf000-0xffff window, which cannot be correct. Work around this by ignoring _CRS on this system. The downside is that we may not assign resources correctly to hot-added PCI devices (if they are possible on this system).
