Subject: [046/117] Revert "memory-hotplug: add 0x prefix to HEX block_size_bytes"

2.6.33-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Linus Torvalds <torvalds@...ux-foundation.org>

commit 4dc86ae1f925b2121d4e75058675895f83e54c71 upstream.

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.
