This patch breaks the build on ARM:

gcc -O1 -fno-omit-frame-pointer -marm -g -fno-strict-aliasing -std=gnu99 -Wall 
-Wstrict-prototypes -Wdeclaration-after-statement -Wno-unused-but-set-variable

smmu.c: In function 'arm_smmu_reassign_dev':
smmu.c:2712:9: error: too few arguments to function 'arm_smmu_assign_dev'
   ret = arm_smmu_assign_dev(t, devfn, dev);
smmu.c:2607:12: note: declared here

/local/scratch/ianj/xen.git/xen/Rules.mk:168: recipe for target 'smmu.o' failed
make[6]: *** [smmu.o] Error 1

I had a quick look but it's not a simple matter of plumbing through an
additional flags parameter becuase the reassign_device method
apparently doesn't take flags.

Tiejun, please can you send a patch to fix this up.  Please send just
a revised version of this patch.  I think the rest of the series will
rebase just fine on top of it.  (If I'm wrong then we will need to do
something more complex.)
