[Xen-devel] [PATCH] tmem should default off for 32-bit Xen

[Dan Magenheimer <dan.magenheimer@xxxxxxxxxx>]

While tmem has gotten limited testing with a 32-bit Xen, it
has severe limitations due to 32-bit heap restrictions.
So, turn it off by default for 32-bit so nobody accidentally
runs into this.
