HI,

when compiling kvm user space on the lastest kernel tree,

the compile FAIL; but on 2.6.29, this compile has succeeded.

The version of the lastest kernel tree is

[root@fedora9 linux-2.6 {master}]$ git describe
v2.6.29-9854-gd508afb

[root@fedora9 kvm-userspace {master}]$ make
.......
rm -f include/asm include-compat/asm
ln -sf asm-x86 include/asm
ln -sf asm-x86 include-compat/asm
make -C /home/zwu/kernel/linux-2.6/ M=`pwd` \
LINUXINCLUDE="-I`pwd`/include -Iinclude \
\
-Iarch/x86/include -I`pwd`/include-compat \

-include `pwd`/x86/external-module-compat.h "

make[1]: *** [all] Error 2

It seems that the macro "CONFIG_MMU_NOTIFIER" is undefined in the
lastest kernel tree.

Cheers,
