Subject: tmem: Only enable by default for x86_64
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~12784
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https://%22%22/%22http:/www.example.com/cgi/%22https:/%22%22?a=commitdiff_plain;h=bf3f5a47a09bfac278c08679bd142869e55df19d;p=xen.git

tmem: Only enable by default for x86_64

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.
