Subject: [PATCH 14/14] xtensa: reword ARCH_FORCE_MAX_ORDER prompt and help text
Date: Thu, 23 Mar 2023 11:21:56 +0200 [thread overview]
Message-ID: <20230323092156.2545741-15-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.
Signed-off-by: Mike Rapoport (IBM) <rppt@kernel.org>

- int "Maximum zone order"
+ int "Order of maximal physically contiguous allocations"
default "10"
help
- 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.
+
+ Don't change if unsure.
