The patch titled
Clean up ELF note generation
has been removed from the -mm tree. Its filename was
clean-up-elf-note-generation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Clean up ELF note generation
From: Jeremy Fitzhardinge <jeremy@xxxxxxxx>
Three cleanups:
1: ELF notes are never mapped, so there's no need to have any access
flags in their phdr.
2: When generating them from asm, tell the assembler to use a SHT_NOTE
section type. There doesn't seem to be a way to do this from C.
3: Use ANSI rather than traditional cpp behaviour to stringify the
macro argument.
