Subject: [PATCH 3.4 101/107] x86/LDT: Print the real LDT base address

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

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

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


commit 0d430e3fb3f7cdc13c0d22078b820f682821b45a upstream.

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