[ Upstream commit ddefc033 ] The commit referenced below introduced device locking around save and restore of state for each device during a PCI bus "try" reset, making it decidely non-"try" and prone to deadlock in the event that a device is already locked. Restore __pci_reset_bus() and __pci_reset_slot() to their advertised locking semantics by pushing the save and restore functions into the branch where the entire tree is already locked. Extend the helper function names with "_locked" and update the comment to reflect this calling requirement.

[ Upstream commit 15d90a6a ] earth-pt1 driver was decomposed/restructured by the commit b732539e ("media: dvb: earth-pt1: decompose pt1 driver into sub drivers"), but it introduced a problem regarding concurrent streaming: Opening a new terrestial stream stops the reception of an existing, already-opened satellite stream. The demod IC in earth-pt1 boards contains 2 pairs of terr. and sat. blocks, supporting 4 concurrent demodulations, and the above problem was because the config of a terr. block contained whole reset/init of the pair blocks, thus each open() of a terrestrial frontend wrongly cleared the config of its peer satellite block of the demod. This whole/pair reset should be executed earlier and not on each open(). Fixes: b732539e ("media: dvb: earth-pt1: decompose pt1 driver into sub drivers") Signed-off-by:

[ Upstream commit ca70ea43 ] MCPM does a soft reset of the CPUs and uses common cpu_resume() routine to perform low-level platform initialization. This results in a try to install HYP stubs for the second time for each CPU and results in false HYP/SVC mode mismatch detection. The HYP stubs are already installed at the beginning of the kernel initialization on the boot CPU (head.S) or in the secondary_startup() for other CPUs. To fix this issue MCPM code should use a cpu_resume() routine without HYP stubs installation. This change fixes HYP/SVC mode mismatch on Samsung Exynos5422-based Odroid XU3/XU4/HC1 boards.

[ Upstream commit c60f83b8 ] Currently, the address range calculation for file-based filters works as long as the vma that maps the matching part of the object file starts from offset zero into the file (vm_pgoff==0). Otherwise, the resulting filter range would be off by vm_pgoff pages. Another related problem is that in case of a partially matching vma, that is, a vma that matches part of a filter region, the filter range size wouldn't be adjusted. Fix the arithmetics around address filter range calculations, taking into account vma offset, so that the entire calculation is done before the filter configuration is passed to the PMU drivers instead of having those drivers do the final bit of arithmetics.

[ Upstream commit 8cfaf106 ] In cpufeatures_process_feature(), if a provided CPU feature is unknown and enable_unknown is false, we erroneously print that the feature is being enabled and return true, even though no feature has been enabled, and may also set feature bits based on the last entry in the match table. Fix this so that we only set feature bits from the match table if we have actually enabled a feature from that table, and when failing to enable an unknown feature, always print the "not enabling" message and return false. Coincidentally, some older gccs (<GCC 7), when invoked with -fsanitize-coverage=trace-pc, cause a spurious uninitialised variable warning in this function: arch/powerpc/kernel/dt_cpu_ftrs.c: In function ‘cpufeatures_process_feature’: arch/powerpc/kernel/dt_cpu_ftrs.c:686:7: warning: ‘m’ may be used uninitialized in this function [-Wmaybe-uninitialized] if (m->cpu_ftr_bit_mask) An upcoming patch will enable support for kcov, which requires this option.

[ Upstream commit 9c2054a5 ] When a DSA port is added to a bridge and brought up, the resulting STP state programmed into the hardware depends on the order that these operations are performed. However, the Linux bridge code believes that the port is in disabled mode. If the DSA port is first added to a bridge and then brought up, it will be in blocking mode. If it is brought up and then added to the bridge, it will be in disabled mode. This difference is caused by DSA always setting the STP mode in dsa_port_enable() whether or not this port is part of a bridge. Since bridge always sets the STP state when the port is added, brought up or taken down, it is unnecessary for us to manipulate the STP state. Apparently, this code was copied from Rocker, and the very next day a similar fix for Rocker was merged but was not propagated to DSA. See e47172ab ("rocker: put port in FORWADING state after leaving bridge") Fixes: b73adef6 ("net: dsa: integrate with SWITCHDEV for HW bridging") Signed-off-by:

[ Upstream commit 36003d4c ] Commit 4c06c4e6 ("driver core: Fix possible supplier PM-usage counter imbalance") introduced a regression that causes suppliers to be suspended prematurely for device links added during consumer driver probe if the initial PM-runtime status of the consumer is "suspended" and the consumer is resumed after adding the link and before pm_runtime_put_suppliers() is called. In that case, pm_runtime_put_suppliers() will drop the rpm_active refcount for the link by one and (since rpm_active is equal to two after the preceding consumer resume) the supplier's PM-runtime usage counter will be decremented, which may cause the supplier to suspend even though the consumer's PM-runtime status is "active". For this reason, partially revert commit 4c06c4e6 as the problem it tried to fix needs to be addressed somewhat differently, and change pm_runtime_get_suppliers() and pm_runtime_put_suppliers() so that the latter only drops rpm_active references acquired by the former. [This requires adding a new field to struct device_link, but I coulnd't find a cleaner way to address the issue that would work in all cases.] This causes pm_runtime_put_suppliers() to effectively ignore device links added during consumer probe, so device_link_add() doesn't need to worry about ensuring that suppliers will remain active after pm_runtime_put_suppliers() for links created with DL_FLAG_RPM_ACTIVE set and it only needs to bump up rpm_active by one for those links, so pm_runtime_active_link() is not necessary any more.
