2.6.26-stable review patch. If anyone has any objections, please let us know. ------------------ From: David Winn commit 08650869e0ec581f8d88cfdb563d37f5383abfe2 upstream Commit 22af89aa0c0b4012a7431114a340efd3665a7617 ("fbcon: replace mono_col macro with static inline") changed the order of operations for computing monochrome color values. This generates 0xffff000f instead of 0x0000000f for a 4 bit monochrome color, leading to image corruption if it is passed to cfb_imageblit or other similar functions. Fix it up.
