Subject: [IA64] SAL work around for windows 2003.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~14211

[IA64] SAL work around for windows 2003.

Temporal work around of SAL emulation for Windows
Some windows crashes with 17606:b03e24f9c1d8. This patch
temporally works around the issue.
The right fix is to support those SAL calls with GFW.
