* docs: complete bumping minimal GNU Make version to 3.81Max Filippov2017-05-061-1/+1
| | | | | | | | | Commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81") changes one entry of GNU make version in the changes.rst, there's still one more entry saying that one need version 3.80. Fix that. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* docs: bump minimal GNU Make version to 3.81Masahiro Yamada2017-05-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 2014, you can't successfully build kernels with GNU Make version 3.80. Example errors: $ git describe v4.11 $ make --version | head -1 GNU Make 3.80 $ make defconfig HOSTCC scripts/basic/fixdep scripts/Makefile.host:135: *** missing separator. Stop. make: *** [defconfig] Error 2 $ make ARCH=arm64 help arch/arm64/Makefile:43: *** unterminated call to function `warning': missing `)'. Stop. $ make help >/dev/null ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional. Stop. make: *** [help] Error 2 The first breakage was introduced by commit c8589d1e9e01 ("kbuild: handle multi-objs dependency appropriately"). Since then (i.e. v3.18), GNU Make 3.80 has not been able to compile the kernel, but nobody has ever complained aboutt (or noticed) it. Even GNU Make 3.81 is more than 10 years old. It would not hurt to match the documentation with reality instead of fixing makefiles.

Apart from two fixes pulls, everything should have been in drm-next for at least 2 weeks. The biggest thing in here is AMD released the public headers for their upcoming VEGA GPUs. These as always are quite a sizeable chunk of header files. They've also added initial non-display support for those GPUs, though they aren't available in production yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Documentation/process/4.Coding.rst there were a couple of paragraphs that spilled over the 80 character line length. This was likely caused when the document was converted to reStructuredText. Re-flow the paragraphs and make the document references proper reStructuredText :ref: links. This also adds the appropriate reStructuredText file heading to kernel-parameters.rst as referenced by the kernel-parameters link in this patch.
