Subject: Fix 64-bit vsprintf.
X-Git-Tag: v2008.10-rc1~808^2~27
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bf05293973b348f6946c9df92cd3c65ece42d0be;p=platform%2Fkernel%2Fu-boot.git

Fix 64-bit vsprintf.

There were some size and unsigned problems.
Also add support for "ll" size modifier in format string like glibc
