hi

I am trying to build the 2.4 32-bit (both HEAD and 2_4_23) kernel for the 
rm5231 cpu - both the cobalt and the ite8172 configurations (just using the 
default configurations from arch/mips/). I get the 
following error due to the changes made to support multiple page sizes. 
Looking at the code, this probably affects all configurations except for the 
ones that use MIPS32 (it seems that these configurations - for example the 
malta, actually do not ever use _PTE_T_LOG2) which include tlbex-mips32.S. 
The code from offset.c 
seems to generate a offset.h which has _PTE_T_LOG2 defined to be $2. Here is 
the snippet from the offset.h -

#define _PGD_T_LOG2    $2
#define _PMD_T_LOG2    $2
#define _PTE_T_LOG2    $2

Is something wrong with the code, or with my configuration?

Thanks
