Doh. Could you please do the following for now?
- unsigned long addr, mapping_size;
+ unsigned long addr, mapping_size = 0;
I'd like to delay spinning v6 with this until I see any input you might
have on the rest of the set.
And for future reference, how are you ending up with
-Werror=maybe-uninitialized? On powerpc/next, with pseries_le_defconfig,
I get -Wno-maybe-uninitialized.
