Subject: [PATCH AUTOSEL 5.15 3/5] drm/vmwgfx: Fix missing HYPERVISOR_GUEST dependency

From: Alexey Makhalov <alexey.makhalov@...adcom.com>

[ Upstream commit 8c4d6945fe5bd04ff847c3c788abd34ca354ecee ]

VMWARE_HYPERCALL alternative will not work as intended without VMware guest code
initialization.

  [ bp: note that this doesn't reproduce with newer gccs so it must be
    something gcc-9-specific. ]
