Ah, my fault. I changed the handling of "codepage" options, but it wasn't
mentioned on changelog at all. (Sorry, I didn't notice this changes.)

Now, the codepage option recognizes only real NLS codepage module.
(It uses FAT_DEFAULT_CODEPAGE, not NLS_DEFAULT. And FAT_DEFAULT_CODEPAGE
only recognizes the numbers.)

Previously, it recognized/loaded all NLS modules via CONFIG_NLS_DEFAULT,
if it can't load the nls_cp437.ko or specified codepage.

But this is seriously wrong. For example, if fatfs using the
nls_utf8.ko for codepage, it will store the wrong 8.3-alias to
disk. (At least, windows can't read this. And several peoples reported
this problem.)

Anyway, could you please check FAT_DEFAULT_CODE/FAT_DEFAULT_IOCHARSET
and NLS_xxx in your .config.

Yes, this should be done automatically by config system. However...
