+Subject: block: change all __u32 annotations to __be32 in affs_hardblocks.h
+
+From: Michael Schmitz <schmitzmic@gmail.com>
+
+commit 95a55437dc49fb3342c82e61f5472a71c63d9ed0 upstream.
+
+The Amiga partition parser module uses signed int for partition sector
+address and count, which will overflow for disks larger than 1 TB.
+
+Use u64 as type for sector address and size to allow using disks up to
+2 TB without LBD support, and disks larger than 2 TB with LBD. The RBD
+format allows to specify disk sizes up to 2^128 bytes (though native
+OS limitations reduce this somewhat, to max 2^68 bytes), so check for
+u64 overflow carefully to protect against overflowing sector_t.
+
+This bug was reported originally in 2012, and the fix was created by
+the RDB author, Joanne Dow <jdow@earthlink.net>. A patch had been
+discussed and reviewed on linux-m68k at that time but never officially
+submitted (now resubmitted as patch 1 of this series).
+
+Patch 3 (this series) adds additional error checking and warning
+messages. One of the error checks now makes use of the previously
+unused rdb_CylBlocks field, which causes a 'sparse' warning
+(cast to restricted __be32).
+
+Annotate all 32 bit fields in affs_hardblocks.h as __be32, as the
+on-disk format of RDB and partition blocks is always big endian.
