[PATCH] vsprintf: use %pR, %pr instead of %pRt, %pRf

From: Bjorn Helgaas
Date: Tue Oct 27 2009 - 15:27:08 EST

Jesse accidentally applied v1 [1] of the patchset instead of v2 [2]. This
is the diff between v1 and v2.

The changes in this patch are:
- tidied vsprintf stack buffer to shrink and compute size more
accurately
- use %pR for decoding and %pr for "raw" (with type and flags) instead
of adding %pRt and %pRf

[1] http://lkml.org/lkml/2009/10/6/491
[2] http://lkml.org/lkml/2009/10/13/441
