Subject: Linux 3.14-rc0 + Merge branch 'akpm' (incoming from Andrew - Mon Jan
27) + Xen + i386 dom0 = BOOM
If I boot a kernel that is built on
commit 1b17366d695c8ab03f98d0155357e97a427e1dce
Merge: d12de1e 7179ba5
Author: Linus Torvalds <torvalds@...ux-foundation.org>
Date: Mon Jan 27 21:11:26 2014 -0800
Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
it boots .
But if I boot with
commit 54c0a4b46150db1571d955d598cd342c9f1d9657
Merge: 1b17366 c2218e2

Merge branch 'akpm' (incoming from Andrew)
it blows up.
