Subject: [PATCH 06/14] m68k: reword ARCH_FORCE_MAX_ORDER prompt and help text
Date: Thu, 23 Mar 2023 11:21:48 +0200	[thread overview]
Message-ID: <20230323092156.2545741-7-rppt@kernel.org> (raw)
In-Reply-To: <20230323092156.2545741-1-rppt@kernel.org>

From: "Mike Rapoport (IBM)" <rppt@kernel.org>

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
-	  blocks into "zones", where each zone is a power of two number of
-	  pages.  This option selects the largest power of two that the kernel
-	  keeps in the memory allocator.  If you need to allocate very large
-	  blocks of physically contiguous memory, then you may need to
-	  increase this value.
+	  The kernel page allocator limits the size of maximal physically
+	  contiguous allocations. The limit is called MAX_ORDER and it
+	  defines the maximal power of two of number of pages that can be
+	  allocated as a single contiguous block. This option allows
+	  overriding the default setting when ability to allocate very
+	  large blocks of physically contiguous memory is required.
 
 	  For systems that have holes in their physical address space this
 	  value also defines the minimal size of the hole that allows
 	  freeing unused memory map.
 
+	  Don't change if unsure.
