+Subject: ima: Allow template selection with ima_template[_fmt]= after ima_hash=
+
+From: Roberto Sassu <roberto.sassu@huawei.com>
+
+commit bb8e52e4906f148c2faf6656b5106cf7233e9301 upstream.
+
+Commit c2426d2ad5027 ("ima: added support for new kernel cmdline parameter
+ima_template_fmt") introduced an additional check on the ima_template
+variable to avoid multiple template selection.
+
+Unfortunately, ima_template could be also set by the setup function of the
+ima_hash= parameter, when it calls ima_template_desc_current(). This causes
+attempts to choose a new template with ima_template= or with
+ima_template_fmt=, after ima_hash=, to be ignored.
+
+Achieve the goal of the commit mentioned with the new static variable
+template_setup_done, so that template selection requests after ima_hash=
+are not ignored.
+
+Finally, call ima_init_template_list(), if not already done, to initialize
+the list of templates before lookup_template_desc() is called.

+Because of the possible failure of the dma_supported(), the

+Therefore, it should be better to check it and return the error if

+And since the sdhci_setup_host() has already checked the return value of
+the enable_dma, we need not check it in sdhci_resume_host() again.

+From: Pavel Parkhomenko <Pavel.Parkhomenko@baikalelectronics.ru>
+
+commit aec12836e7196e4d360b2cbf20cf7aa5139ad2ec upstream.
+
+When setting up autonegotiation for 88E1118R and compatible PHYs,
+a software reset of PHY is issued before setting up polarity.
+This is incorrect as changes of MDI Crossover Mode bits are
+disruptive to the normal operation and must be followed by a
+software reset to take effect. Let's patch m88e1118_config_aneg()
+to fix the issue mentioned before by invoking software reset
+of the PHY just after setting up MDI-x polarity.

+Subject: net: phy: marvell: Fix RGMII Tx/Rx delays setting in 88e1121-compatible PHYs
+
+From: Pavel Parkhomenko <Pavel.Parkhomenko@baikalelectronics.ru>
+
+commit fe4f57bf7b585dca58f1496c4e2481ecbae18126 upstream.
+
+It is mandatory for a software to issue a reset upon modifying RGMII
+Receive Timing Control and RGMII Transmit Timing Control bit fields of MAC
+Specific Control register 2 (page 2, register 21) otherwise the changes
+won't be perceived by the PHY (the same is applicable for a lot of other
+registers). Not setting the RGMII delays on the platforms that imply it'
+being done on the PHY side will consequently cause the traffic loss. We
+discovered that the denoted soft-reset is missing in the
+m88e1121_config_aneg() method for the case if the RGMII delays are
+modified but the MDIx polarity isn't changed or the auto-negotiation is
+left enabled, thus causing the traffic loss on our platform with Marvell
+Alaska 88E1510 installed. Let's fix that by issuing the soft-reset if the
+delays have been actually set in the m88e1121_config_aneg_rgmii_delays()
+method.
