[merged mm-stable] powerpc-reword-arch_force_max_order-prompt-and-help-text.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: powerpc: reword ARCH_FORCE_MAX_ORDER prompt and help text
has been removed from the -mm tree.  Its filename was
     powerpc-reword-arch_force_max_order-prompt-and-help-text.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: powerpc: reword ARCH_FORCE_MAX_ORDER prompt and help text
Date: Fri, 24 Mar 2023 08:22:28 +0300

The prompt and help text of ARCH_FORCE_MAX_ORDER are not even close to
describe this configuration option.

Update both to actually describe what this option does.

-	  The kernel memory allocator divides physically contiguous memory
