The following are my commands to build toolchian

USE="-*" UCLIBC_CPU=ARM920T crossdev -v -t armeb-softfloat-linux-uclibc --b
2.18-r1 --g 3.4.6-r2 --k 2.6.25-r2 --l 0.9.28.3-r3
USE="-*" UCLIBC_CPU=ARM920T crossdev -v -t armeb-softfloat-linux-uclibc --b
2.18-r1 --g 3.4.6-r2 --k 2.6.25-r2 --l 0.9.28.3-r6

Both failed with the following messages:

It looks like the header file "asm/page.h" is obsoleted in 2.6.25-r2, so
uclibc cannot be compiled due to the missing header file.
Any solution to this? Thanks.

none of this is actually relevant ...

i thought Ned included a patch for this in newer 0.9.28 versions ... you could 
just touch the "asm/page.h" file in your kernel dir to work around the issue
