Subject: [PATCH v3 13/14] include/linux/compiler.h: remove unused KENTRY macro
Date: Wed, 28 Aug 2019 15:55:34 -0700 [thread overview]
Message-ID: <20190828225535.49592-14-ndesaulniers@google.com> (raw)
In-Reply-To: <20190828225535.49592-1-ndesaulniers@google.com>
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.
Tested-by: Sedat Dilek <sedat.dilek@gmail.com>

- * 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.
