+Subject: ALSA: hda: Match both PCI ID and SSID for driver blacklist
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 977dfef40c8996b69afe23a9094d184049efb7bb upstream.
+
+The commit 3c6fd1f07ed0 ("ALSA: hda: Add driver blacklist") added a
+new blacklist for the devices that are known to have empty codecs, and
+one of the entries was ASUS ROG Zenith II (PCI SSID 1043:874f).
+However, it turned out that the very same PCI SSID is used for the
+previous model that does have the valid HD-audio codecs and the change
+broke the sound on it.
+
+Since the empty codec problem appear on the certain AMD platform (PCI
+ID 1022:1487), this patch changes the blacklist matching to both PCI
+ID and SSID using pci_match_id(). Also, the entry that was removed by
+the previous fix for ASUS ROG Zenigh II is re-added.

+Subject: dma-direct: exclude dma_direct_map_resource from the min_low_pfn check
+
+From: Christoph Hellwig <hch@lst.de>
+
+commit 68a33b1794665ba8a1d1ef1d3bfcc7c587d380a6 upstream.
+
+The valid memory address check in dma_capable only makes sense when mapping
+normal memory, not when using dma_map_resource to map a device resource.
+Add a new boolean argument to dma_capable to exclude that check for the
+dma_map_resource case.
+
+Fixes: b12d66278dd6 ("dma-direct: check for overflows on 32 bit DMA addresses")

+The commit 842f4be95899 ("KVM: VMX: Add a trampoline to fix VMREAD error
