[merged] dma-debug-switch-check-from-_text-to-_stext.patch removed from -mm tree

The patch titled
     Subject: dma-debug: switch check from _text to _stext
has been removed from the -mm tree.  Its filename was
     dma-debug-switch-check-from-_text-to-_stext.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Laura Abbott <redacted>
Subject: dma-debug: switch check from _text to _stext

In include/asm-generic/sections.h:

/*
 * Usage guidelines:
 * _text, _data: architecture specific, don't use them in
 * arch-independent code
 * [_stext, _etext]: contains .text.* sections, may also contain
 * .rodata.*
 *                   and/or .init.* sections

_text is not guaranteed across architectures.  Architectures such as ARM
may reuse parts which are not actually text and erroneously trigger a bug.
Switch to using _stext which is guaranteed to contain text sections.
