[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 3/5] xen/x86: Shuffle use of __attribute__((packed))
This is almost all manual shuffling of __attribute__((packed)) statements to
__packed at the head of the structure.
The only different change is in tboot.h, removing some now-redundant ifdefs.
