[fuse-devel] Problem (and solution): fuse 2.6.3 on arm with 2.6.18

[Torsten H. <tor...@se...>]

Hello,

I tried to compile the fuse driver for the nokia n800 (arm architecture)
with linux 2.6.18 (requiring the DCACHE_BUG workaround) and got the
following message while compiling:

...
  CC [M]  /home/thilbrich/kernel/fuse-2.6.3/kernel/control.o
  LD [M]  /home/thilbrich/kernel/fuse-2.6.3/kernel/fuse.o
  Building modules, stage 2.
  MODPOST
WARNING: "flush_cache_page"
[/home/thilbrich/kernel/fuse-2.6.3/kernel/fuse.ko] u ndefined!
  LD [M]  /home/thilbrich/kernel/fuse-2.6.3/kernel/fuse.ko
make[1]: Leaving directory
`/home/thilbrich/kernel/kernel-source-rx-34-2.6.18'

I checked both the nokia kernel and the vanilla kernel and, indeed, the
symbol "flush_cache_page" is not exported.  Of course, the module was
unloadable.

I finally copied the necessary code from the kernel to the module using
the patch attached to this message.

Note: I also tested the module from the kernel distribution but
obviously ran into the DCACHE_BUG.
