[PATCH v2 13/14] include/linux/compiler.h: remove unused KENTRY macro

From: Nick Desaulniers
Date: Tue Aug 27 2019 - 16:41:07 EST


This macro is not used throughout the kernel. Delete it rather than
update the __section to be a fully spelled out
__attribute__((__section__())) to avoid
https://bugs.llvm.org/show_bug.cgi?id=42950.

- * KENTRY - kernel entry point
- * This can be used to annotate symbols (functions or data) that are used
- * without their linker symbol being referenced explicitly. For example,
- * interrupt vector handlers, or functions in the kernel image that are found
- * programatically.
- *
- * Not required for symbols exported with EXPORT_SYMBOL, or initcalls. Those
- * are handled in their own way (with KEEP() in linker scripts).
- *
- * KENTRY can be avoided if the symbols in question are marked as KEEP() in the
- * linker script. For example an architecture could KEEP() its entire
- * boot/exception vector code rather than annotate each function and data.
