Subject: vmlinux.lds.h update
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7923f90fffa8746f6457d4eea2109fd3d6414189;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

vmlinux.lds.h update

Updated after review by Tim Abbott.
- Use HEAD_TEXT_SECTION
- Drop use of section-names.h and delete file
- Introduce EXIT_CALL

Deleting section-names.h required a few simple
updates of init.h
