Back in the day we relied on a default value that used to be 8KiB
and it worked perfectly fine for ARC's default 8KiB page as well as
4 KiB ones, but not for 16 KiB, see [1] for more details.
So that we fixed by setting "max-page-size" if 16KiB pages are in use by
commit d024d369b8 ("arch/arc: Accommodate 16 KiB MMU pages").
But as Yann very rightfully mentioned here [2] we should be setting this
thing explicitly for all page sizes because:
1. Defaults might change unexpectedly
2. Explicitly set stuff is better understood
3. We act similarly to all settings but not only addressing some corner cases

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
