Subject: mm-merge-nopfn-into-fault spufs fix
From: Cedric Le Goater <clg@xxxxxxxxxx>
Here's a tentative fix for mm-merge-nopfn-into-fault.patch.
./arch/powerpc/platforms/cell/spufs/file.c: In function 'spufs_mem_mmap_fault':
./arch/powerpc/platforms/cell/spufs/file.c:122: error: 'address' undeclared (first use in this function)
./arch/powerpc/platforms/cell/spufs/file.c:122: error: (Each undeclared identifier is reported only once
./arch/powerpc/platforms/cell/spufs/file.c:122: error: for each function it appears in.)
./arch/powerpc/platforms/cell/spufs/file.c:141: error: expected ';' before 'if'
./arch/powerpc/platforms/cell/spufs/file.c:122: warning: unused variable 'addr0'
I'm not sure how useful is the addr0 variable.
