gcc-fix-put-user.patch doesn't apply cleanly to any kernel that
includes commit 538094 ("ARM: 8051/1: put_user: fix possible data
corruption in put_user") or a backport of it because the surrounding
lines (context) of the patch are different:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=537094b64b229bf3ad146042f83e74cf6abe59df
This commit fixes the problem by removing the context from the patch. It
also changes linux-sony-amami, linux-sony-aries, and linux-sony-taoshan
to use the shared patch.
I have confirmed that all six affected kernels still compile. [skip ci]
All kernels compile again, after the GCC 8 upgrade.
All 3.x kernels have been changed to use GCC 6 now, because we can't
say for sure that they boot with GCC 8 even if we made them compile
with that newer GCC. If someone wants to test a kernel for a newer
device which they can test, see the instructions on
<https://postmarketos.org/vendorkernel>.
The linux-sony-castor-windy 4.x kernel did not compile out of the box
with the latest GCC, so we set it to GCC 6 as well. This can probably
be fixed easily.
linux-teclast-x80-pro: removed Werror and updated to latest 4.14 kernel
from kernel.org, otherwise this would not compile anymore (tested with
both GCC 6 and 8, probably incompatibility with the latest binutils or
something).
This commit will take too long to compile in CI, so let's [skip ci].
I've compiled all kernels multiple times and fixed them up until all of
them were working again.
