Subject: xfs: enhance dinode verifier
Origin: https://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git/commit?id=b42db0860e13067fcc7cbfba3966c9e652668bbc
Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2018-10322
Add several more validations to xfs_dinode_verify:
- For LOCAL data fork formats, di_nextents must be 0.
- For LOCAL attr fork formats, di_anextents must be 0.
- For inodes with no attr fork offset,
- format must be XFS_DINODE_FMT_EXTENTS if set at all
- di_anextents must be 0.
Thanks to dchinner for pointing out a couple related checks I had
forgotten to add.

Subject: xfs: set format back to extents if xfs_bmap_extents_to_btree
Origin: https://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git/commit?id=2c4306f719b083d17df2963bc761777576b8ad1b
Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2018-10323
If xfs_bmap_extents_to_btree fails in a mode where we call
xfs_iroot_realloc(-1) to de-allocate the root, set the
format back to extents.
Otherwise we can assume we can dereference ifp->if_broot
based on the XFS_DINODE_FMT_BTREE format, and crash.

Subject: parisc: Make bzImage default build target
From: Helge Deller <deller@gmx.de>
Date: Wed, 18 Apr 2018 07:49:19 +0200
Forwarded: https://patchwork.kernel.org/patch/10347405/
Debian uses "make all" to build the Linux kernel, thus to be able to use
the self-decompressing kernel as default debian kernel we need to make
bzImage the default build target.
