3.5.7.23 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: David Vrabel <david.vra...@citrix.com>
commit a9fbf4d591da6cd1d3eaab826c7c15f77fc8f6a3 upstream.
Commit d0380e6c3c0f6edb986d8798a23acfaf33d5df23 (early_printk:
consolidate random copies of identical code) added in 3.10 introduced
a check for con->index == -1 in early_console_register().
Initialize index to -1 for the xenboot console so earlyprintk=xen
works again.
