The patch titled
i386: Put allocated ELF notes in read-only data segment
has been removed from the -mm tree. Its filename was
i386-put-allocated-elf-notes-in-read-only-data-segment.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: i386: Put allocated ELF notes in read-only data segment
From: Roland McGrath <roland@xxxxxxxxxx>
This changes the i386 linker script and the asm-generic macro it uses so that
ELF note sections with SHF_ALLOC set are linked into the kernel image along
with other read-only data. The PT_NOTE also points to their location.
This paves the way for putting useful build-time information into ELF notes
that can be found easily later in a kernel memory dump.
