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

[ Upstream commit 62008578b73f16e274070a232b939ba5933bb8ba ]

Previously we used "%#08x" to print a 32-bit value. This fills an
8-character field with "0x...", but of course many 32-bit values require a
10-character field "0x12345678" for this format. Fix the formats to avoid
confusion.
