[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: mm: cma: make mm/cma.h self-contained and conditionalize includes
has been removed from the -mm tree.  Its filename was
     mm-cma-make-mm-cmah-self-contained-and-conditionalize-includes.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm: cma: make mm/cma.h self-contained and conditionalize includes
Date: Sat, 15 Aug 2026 10:32:45 +0000

mm/cma.h uses types from <linux/spinlock.h>, <linux/mutex.h>,
<linux/atomic.h> and <linux/list.h> without explicitly including them,
violating the kernel header self-containment guidelines.

<linux/debugfs.h> and <linux/kobject.h> are also included unconditionally
even though they are only needed under CONFIG_CMA_DEBUGFS and
CONFIG_CMA_SYSFS respectively.  Move the struct cma_kobject definition and
<linux/kobject.h> inside the CONFIG_CMA_SYSFS block, and move
<linux/debugfs.h> inside CONFIG_CMA_DEBUGFS.

Remove spurious trailing semicolons after the empty inline function bodies
in the CONFIG_CMA_SYSFS #else branch.

Add <linux/cma.h> so that MAX_CMA_AREAS and CMA_MAX_NAME are always
available when this header is included.
