Subject: [PATCH 3.12 77/88] EDAC: Remove arbitrary limit on number of channels

From: Tony Luck <tony.luck@...el.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit c44696fff04ff62f65441afe9ea244b47653dd6d upstream.

Currently set to "6", but the reset of the code will dynamically
allocate as needed.  We need to go to "8" today, but drop the check
completely to save doing this again when we need even larger numbers.
