Andrew,

I can't compile 2.6.9-rc1-mm3, because of this:

  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
fs/built-in.o(.text+0x9d170): In function `gzip1_alloc':
: undefined reference to `in_softirq'
fs/built-in.o(.text+0x9d1b3): In function `gzip1_alloc':
: undefined reference to `in_softirq'
make: *** [.tmp_vmlinux1] Error 1

Attached is the .config.

Regards,
RJW
