Hi Jim,
I have downloaded 2.6.18 sanitized headers from the following link which was suggested by you.
I am trying to build the toolchain for MIPS for linux-2.6.18 kernel using these headers and uClibc-0.9.28 and gcc-3.4.3.
When i tried to compile busybox-1.00 i get the following error
"undefined reference to `getpageshift' ".
Then i searched in the mailing list and found your article
I added the following definition for getpageshift(), suggested in the above link in the asm-mips/page.h file
Here is a santized
version

I am not able to find definition for getpagesize().Can you please help me finding the definition for same. Is it in kernel or in userland?.
BTW:
I tried the same thing on Linux-2.6.17.13. I could build the toolchain by modifying the page.h as mentioned above. I could build the images for both Linux-2.6.17.13 and root file system for MIPS processor.But when i tried to execute any command pointing to busybox i was getting kernel crash.
When i tried to debug this issue i found that
"asm/page.h" file is included in some of the files in the busybox.
Is this crash because of getpageshift() which is defined in asm-mips/page.h.?.
What is the expected output of getpagesize()?.
Could you advise a solution for this?.
Regards,
Sathesh

Actually my Cross-LFS team has created a sanitation script to clean the
headers, you can get the script from http://headers.cross-lfs.org, or
you can download a bundle from http://ftp.jg555.com/headers
