2.6.26-stable review patch. If anyone has any objections, please let us know. ------------------ From: Petr Tesarik commit 938bb03d188a1e688fb0bcae49788f540193e80a uptream Aesthetic regards aside, commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667 still leaves a bug in the error message, because it uses the unconverted big-endian value for printk. Fix this by using a local variable in machine byte order. The result is correct, more readable, and also produces slightly shorter code on i386.
