Description Ben Kero 2009-08-19 18:25:40 UTC

Trying to upgrade kernels on some powerpc equipment, reach the same error on powe5 and a G5.  sys-kernel/hardened-sources-2.6.28-r7 to 2.6.29 all break with the following error:

/usr/src/linux-2.6.28-hardened-r7/arch/powerpc/include/asm/mman.h:41: error: 'VM_SAO' undeclared (first use in this function)

Reproducible: Always

Steps to Reproduce:
1. emerge =sys-kernel/2.6.28-r7
2. Make your kernel config
3. make

Actual Results:  
Bad error

Expected Results:  
A compiled kernel

Comment 3 Ben Kero 2009-08-19 18:32:05 UTC

Looking through include/linux/mm.h, it seems that things sourced in before line 42 use VM_SAO, and it's therefore undefined when they try.  If I define it at the top of mm.h, it seems to compile without error.

Can you test hardened-sources-2.6.32-r9.  I have a dual core G5 running it no problems.

This kernel is off the tree, and it works with never versions, so I'm closing this bug.
