Subject: Update util.h
X-Git-Tag: 9.0.0-rc1~32
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=443a645cafb0d7a2a5b7eff4c1a5e9976025a720;p=pvdrivers%2Fwin%2Fxencons.git

Update util.h

XENCONS does not use much of the functionality in util.h, including the
__AllocatePages() function modified by this change, however
it is good to keep the header in-sync with the other drivers.
