Felix Fietkau 212aa33226 kernel: enable memory compaction
Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

Alex Maclean 11d6547455 config: extend small_flash feature
Extend the small_flash feature to disable swap, core dumps, and
kernel debug info, and change the squashfs block size to 1024KiB.

Also change squashfs fragment cache to 2 for small_flash to ease memory
usage.

Mathias Kresin cf7154db07 kernel: only optimized for size if small_flash
Add a new config option to allow to select the default compile
optimization level for the kernel.

Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.

Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.

Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.

Exceptions to the above are:

  - lantiq, where the optimization for size is only required for the
    xway_legacy subtarget but was set for the whole target
  - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
    plenty of space and an optimization for size doesn't make much sense
  - rb532, which has 128MByte flash

Rosen Penev 45219c1c0f kernel: Restrict dmesg output to root.
In typical OpenWrt setups, there are no other users that have a shell spawned for them by default.

This can be overriden by the kernel.dmesg_output syssctl.

Felix Fietkau bdd2772f1d kernel: mtdsplit: add support for brnImages
This adds brnImage (used with the brnboot bootloader) firmware parsing
support. brnboot verifies the integrity of the firmware stored on the
"Code Image" partitions by looking at the 12 byte footer at the very end
of the partition. This footer contains the checksum of the original
brnImage (kernel + rootfs/squashfs) and must not be touched (by our JFFS2
rootfs_data - otherwise the image will not be bootable anymore).

Big thanks to Mathias Kresin for analyzing the brnImage structure and
finding out the information how to keep images valid even when adding a
nested rootfs_data partition.
