Liu Shixin via Jfs-discussion 1f4a325933 fs/jfs: fix shift exponent db_agl2size negative 
[ Upstream commit fad376fce0 ]

As a shift exponent, db_agl2size can not be less than 0. Add the missing
check to fix the shift-out-of-bounds bug reported by syzkaller:

 UBSAN: shift-out-of-bounds in fs/jfs/jfs_dmap.c:2227:15
 shift exponent -744642816 is negative

Reported-by: syzbot+0be96567042453c0c820@syzkaller.appspotmail.com
Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
