Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

# Usage: configinit.sh config-spec-file [ build output dir ]
|
|
#
|
|
# Create a .config file from the spec file. Run from the kernel source tree.
|
|
# Exits with 0 if all went well, with 1 if all went well but the config
|
|
# did not match, and some other number for other failures.
|
|
#
|
|
# The first argument is the .config specification file, which contains
|
|
# desired settings, for example, "CONFIG_NO_HZ=y". For best results,
|
|
# this should be a full pathname.
|
|
#
|
|
# The second argument is a optional path to a build output directory,
|
|
# for example, "O=/tmp/foo". If this argument is omitted, the .config
|
|
# file will be generated directly in the current directory.
