Linus Torvalds [Fri, 9 Apr 2010 17:05:33 +0000 (10:05 -0700)]
This reverts commit ba168fc37dea145deeb8fa9e7e71c748d2e00d74.

It changes user-visible sysfs interfaces, and breaks some existing user
space applications which apparently rely on the fact that the output
does not contain the "0x" prefix.
