4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Huacai Chen <redacted>

commit 3484de7bcbed20ecbf2b8d80671619e7059e2dd7 upstream.

Due to datasheet, reserving 0xff800000~0xffffffff (8MB below 4GB) is
not enough for RS780E integrated GPU's TOM (top of memory) registers
and MSI/MSI-x memory region, so we reserve 0xfe000000~0xffffffff (32MB
below 4GB).
