+Subject: afs: Don't cross .backup mountpoint from backup volume
+
+From: Marc Dionne <marc.dionne@auristor.com>
+
+commit 29be9100aca2915fab54b5693309bc42956542e5 upstream.
+
+Don't cross a mountpoint that explicitly specifies a backup volume
+(target is <vol>.backup) when starting from a backup volume.
+
+It it not uncommon to mount a volume's backup directly in the volume
+itself. This can cause tools that are not paying attention to get
+into a loop mounting the volume onto itself as they attempt to
+traverse the tree, leading to a variety of problems.
+
+This doesn't prevent the general case of loops in a sequence of
+mountpoints, but addresses a common special case in the same way
+as other afs clients.

+Subject: mmc: core: Do not force a retune before RPMB switch
+
+From: Jorge Ramirez-Ortiz <jorge@foundries.io>
+
+commit 67380251e8bbd3302c64fea07f95c31971b91c22 upstream.
+
+Requesting a retune before switching to the RPMB partition has been
+observed to cause CRC errors on the RPMB reads (-EILSEQ).
+
+Since RPMB reads can not be retried, the clients would be directly
+affected by the errors.
+
+This commit disables the retune request prior to switching to the RPMB
+partition: mmc_retune_pause() no longer triggers a retune before the
+pause period begins.
+
+This was verified with the sdhci-of-arasan driver (ZynqMP) configured
+for HS200 using two separate eMMC cards (DG4064 and 064GB2). In both
+cases, the error was easy to reproduce triggering every few tenths of
+reads.
+
+With this commit, systems that were utilizing OP-TEE to access RPMB
+variables will experience an enhanced performance. Specifically, when
+OP-TEE is configured to employ RPMB as a secure storage solution, it not
+only writes the data but also the secure filesystem within the
+partition. As a result, retrieving any variable involves multiple RPMB
+reads, typically around five.
+
+For context, on ZynqMP, each retune request consumed approximately
+8ms. Consequently, reading any RPMB variable used to take at the very
+minimum 40ms.
+
+After droping the need to retune before switching to the RPMB partition,
+this is no longer the case.

+Subject: net: sfp-bus: fix SFP mode detect from bitrate
+
+From: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
+
+commit 97eb5d51b4a584a60e5d096bdb6b33edc9f50d8d upstream.
+
+The referenced commit moved the setting of the Autoneg and pause bits
+early in sfp_parse_support(). However, we check whether the modes are
+empty before using the bitrate to set some modes. Setting these bits
+so early causes that test to always be false, preventing this working,
+and thus some modules that used to work no longer do.
+
+Move them just before the call to the quirk.
