kernel module compilation error

[Vijay Nikam]

Hello All,

I upgraded the Linux kernel version from 2.6.20 to 2.6.23 on eval
board mpc8313erdb. Then I wrote a simple hello_world kernel module for
testing but when I do make it gives following compilation error.
Whereas I did not had this problem with kernel 2.6.20 !!!

It says; 'include/asm/current.h:35: error: invalid register name for ‘current’'

Following is complete error log
