2021-02-07compat: redefine version constants for sublevel>=256Jason A. Donenfeld
With the 4.4.256 and 4.9.256 kernels, the previous calculation for integer comparison overflowed. This commit redefines the broken constants to have more space for the sublevel. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2020-04-30compat: timeconst.h is a generated artifactJason A. Donenfeld
Before we were trying to check for timeconst.h by looking in the kernel source directory. This isn't quite correct on configurations in which the object directory is separate from the kernel source directory, for example when using O="elsewhere" as a make option when building the kernel. The correct fix is to use $(CURDIR), which should point to where we want. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

Android kernels backported d35a00b8e33dab7385f724e713ae71c8be0a49f4, so now we need to do feature detection. Link: https://android-review.googlesource.com/c/kernel/common/+/1103831 Signed-off-by: Nathan Chancellor <natechancellor@gmail.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-12-09global: add SPDX tags to all filesGreg Kroah-Hartman
It's good to have SPDX identifiers in all files as the Linux kernel developers are working to add these identifiers to all files. Update all files with the correct SPDX license identifier based on the license text of the project or based on the license in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Modified-by: Jason A.

2017-09-18queue: entirely rework parallel systemJason A. Donenfeld
This removes our dependency on padata and moves to a different mode of multiprocessing that is more efficient. This began as Samuel Holland's GSoC project and was gradually reworked/redesigned/rebased into this present commit, which is a combination of his initial contribution and my subsequent rewriting and redesigning.
