+Subject: cryptoloop: add a deprecation warning
+
+From: Christoph Hellwig <hch@lst.de>
+
+[ Upstream commit 222013f9ac30b9cec44301daa8dbd0aae38abffb ]
+
+Support for cryptoloop has been officially marked broken and deprecated
+in favor of dm-crypt (which supports the same broken algorithms if
+needed) in Linux 2.6.4 (released in March 2004), and support for it has
+been entirely removed from losetup in util-linux 2.23 (released in April
+2013). Add a warning and a deprecation schedule.

+From: Kim Phillips <kim.phillips@amd.com>
+
+[ Upstream commit 26db2e0c51fe83e1dd852c1321407835b481806e ]
+
+Erratum #1197 "IBS (Instruction Based Sampling) Register State May be
+Incorrect After Restore From CC6" is published in a document:

+ "Revision Guide for AMD Family 19h Models 00h-0Fh Processors" 56683 Rev. 1.04 July 2021

+Implement the erratum's suggested workaround and ignore IBS samples if

+
+From: Shai Malin <smalin@marvell.com>
+
+[ Upstream commit b0cd08537db8d2fbb227cdb2e5835209db295a24 ]
+
+For VFs we should return with an error in case we didn't get the exact
+number of msix vectors as we requested.
+Not doing that will lead to a crash when starting queues for this VF.

+
+From: Shai Malin <smalin@marvell.com>
+
+[ Upstream commit e543468869e2532f5d7926e8f417782b48eca3dc ]
+
+Thanks to Kees Cook who detected the problem of memset that starting
+from not the first member, but sized for the whole struct.
+The better change will be to remove the redundant memset and to clear
+only the msix_cnt member.
