Subject: [PATCH 3.2 24/87] x86/LDT: Print the real LDT base address

3.2.77-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Jan Beulich <JBeulich@...e.com>

commit 0d430e3fb3f7cdc13c0d22078b820f682821b45a upstream.

This was meant to print base address and entry count; make it do so
again.
