Subject: [PATCH] vmware-vga: CVE-2014-3689: turn off hw accel

Quick & easy stopgap for CVE-2014-3689:  We just compile out the

hardware acceleration functions which lack sanity checks.  Thankfully

we have capability bits for them (SVGA_CAP_RECT_COPY and

SVGA_CAP_RECT_FILL), so guests should deal just fine, in theory.

Subsequent patches will add the missing checks and re-enable the

hardware acceleration emulation.
