linux-2.6 (2.6.18.dfsg.1-12) UNRELEASED; urgency=low
+ [ Steve Langasek ]
* Set CONFIG_MATHEMU=y on alpha, which is required for proper fp math on
at least ev4-ev56 systems. Closes: #411813.
* linux-image packages need to depend on a newer version of coreutils,
because of the use of readlink -q -m inherited from kernel-package.
Closes: #413311.
+ [ Jurij Smakov ]
+ * Add bugfix/sparc/e450-boot-failure.patch to fix boot failure on
+ E450 machines. Thanks to David Miller for the patch and to Daniel
+ Smolik for testing.
