There is a client side error "Stale file handle" when mounting from a
nfs server running on 32bit arch.
Steps to reproduce:
1. $ MACHINE=qemux86 bitbake core-image-sato
2. $ runqemu qemux86 kvm nographic qemuparams="-m 1024"
3. $ echo "/nfs_root *(insecure,rw,async,no_root_squash,no_subtree_check)" \
>> /etc/exports
$ /etc/init.d/nfsserver restart
root@qemux86:~# mount -t nfs 127.0.0.1:/nfs_root /mnt
mount: mounting 127.0.0.1:/nfs_root on /mnt failed: Stale file handle
Backport a patch to fix this issue.

+Subject: [PATCH] Fix include order between config.h and stat.h
+
+At least on Arch linux ARM, the definition of struct stat in stat.h depends
+on __USE_FILE_OFFSET64. This symbol comes from config.h when defined,
+therefore config.h must always be included before stat.h. Fix all
+occurrences where the order is wrong by moving config.h to the top.
+
+This fixes the client side error "Stale file handle" when mounting from
+a server running Arch Linux ARM.
