Thanks Gavin. I had tried that. The problem is, this particular flag is
not a user-selectable one, and even if I enable it by directly editing the
vendors/.../config.linux, it always gets undone when I actually go and
configure my kernel. This option seems to be forcibly enforced by the
Kconfig. There's got to be some way to keep it without hacking the Kconfig.
Thanks,

</div>You should have a board-specific directory in the "vendors" tree, and \
have<br> that selected as your current board via the top-level uClinux makefile<br>
(CAUTION: if you change the board selection it will replace your current<br>
.config files and do a clean rebuild, so make sure you've saved your current<br>
ones elsewhere if you need to change the selected board and have changes you<br>
wish to preserve).<br>
<br>
One of the options in the top-level makefile's config menu is to save your<br>
modified .config files to the vendors folder as the new defaults for that<br>
board. (Or if you want to do it manually, look at the existing vendor<br>
folders. The naming conventions for the default config files should<br>
hopefully be obvious.)<br>
