+Subject: powerpc/lib/sstep: Fix build errors with newer binutils
+
+From: Anders Roxell <anders.roxell@linaro.org>
+
+commit 8219d31effa7be5dbc7ff915d7970672e028c701 upstream.
+
+Building tinyconfig with gcc (Debian 11.2.0-16) and assembler (Debian
+2.37.90.20220207) the following build error shows up:
+
+ {standard input}: Assembler messages:
+ {standard input}:10576: Error: unrecognized opcode: `stbcx.'
+ {standard input}:10680: Error: unrecognized opcode: `lharx'
+ {standard input}:10694: Error: unrecognized opcode: `lbarx'
+
+Rework to add assembler directives [1] around the instruction. The
+problem with this might be that we can trick a power6 into
+single-stepping through an stbcx. for instance, and it will execute that
+in kernel mode.

+Subject: powerpc/lib/sstep: Fix 'sthcx' instruction
+
+From: Anders Roxell <anders.roxell@linaro.org>
+
+commit a633cb1edddaa643fadc70abc88f89a408fa834a upstream.
+
+Looks like there been a copy paste mistake when added the instruction
+'stbcx' twice and one was probably meant to be 'sthcx'. Changing to
+'sthcx' from 'stbcx'.

+Subject: scsi: qla2xxx: Fix incorrect reporting of task management failure
+
+From: Quinn Tran <qutran@marvell.com>
+
+commit 58ca5999e0367d131de82a75257fbfd5aed0195d upstream.
+
+User experienced no task management error while target device is responding
+with error. The RSP_CODE field in the status IOCB is in little endian.
+Driver assumes it's big endian and it picked up erroneous data.
+
+Convert the data back to big endian as is on the wire.
