* [arm/armel] Add a kernel for Orion based devices, such as the QNAP
TS-109/TS-209.
* [arm/armel] Unset CRYPTO_DEV_HIFN_795X since it causes a build failure.
+ * [arm] Pad the SSB structure so crossing-compiling a kernel for ARM
+ won't fail because of sanity checks; patch from Gordon Farquharson.
[ Daniel Baumann ]
* Added patch from unionfs upstream to export release_open_intent symbol.

+Align the members of the SSB device structure to a 32 bit boundary so
+that the b43 driver can be built for arm using a cross compiler. This
+alignment is required so that the test in scripts/mod/file2alias.c

+FATAL: drivers/net/wireless/b43/b43: sizeof(struct ssb_device_id)=6 is not a
