[patch 0/4] genirq: Clean up license information

[patch 0/4] genirq: Clean up license information

[Thomas Gleixner]

The following patch series cleans up the licensing information in the
generic irq subsystem.

  * Replace boiler plate language and sloppy references with SPDX

  * Add missing SPDX identifiers to files with no license reference

  * Use the proper tag format

While at it clean up the top of file comments by removing pointless
references to the filename itself and condense the information where
appropriate.

Thanks,

	tglx

[patch 4/4] genirq: Add missing SPDX identifiers

[Thomas Gleixner]

[-- Attachment #1: genirq--Add-missing-SPDX-identifiers.patch --]
[-- Type: text/plain, Size: 2751 bytes --]

These files do not contain a license reference and were not updated in the
initial SPDX conversion because the license was deduced by the scanners via
EXPORT_SYMBOL_GPL as GPL2.0 only.

Add the missing GPL-2.0 identifiers.

genirq: Add missing SPDX identifiers

Add SPDX identifiers to files

 - which contain an explicit license boiler plate or reference

 - which do not contain a license reference and were not updated in the
   initial SPDX conversion because the license was deduced by the scanners
   via EXPORT_SYMBOL_GPL as GPL2.0 only.

[ tglx: Moved adding identifiers from the patch which removes the
  	references/boilerplate ]

Hello.

What do you think of the proposal to convert all the tags
to the "-or-later" and "-only" variants that the
https://spdx.org/licenses/ uses today?

Ick ick ick ick.  Let's stick with what we have today, if we do decide

Why would it be foolish to have the kernel
match the spdx license text?
