[Xen-devel] [PATCH v5 1/8] hvmloader: Remove all 64-bit print arguments

[George Dunlap <george.dunlap@xxxxxxxxxxxxx>]

The printf() available to hvmloader does not handle 64-bit data types;
manually break them down as two 32-bit strings.

v4:
 - Make macros for the requisite format and bit shifting
