X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d955d90b90db4b3ac2a3e56d271f372c41fb00d6;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [PATCH] IP27: Really set PCI64_ATTR_VIRTUAL, not PCI64_ATTR_PREC. IOC3's homegrown DMA mapping functions that are used to optimize things a little on IP27 set the wrong bit.
