[ Upstream commit 2fd0f46c ] In usecases where force_port_map is used saved_port_map is never set, resulting in not programming the PORTS_IMPL register as part of initial config. This patch fixes this by setting it to port_map even in case where force_port_map is used, making it more inline with other parts of the code. Fixes: 566d1827 ("libata: disable forced PORTS_IMPL for >= AHCI 1.3") Cc: stable@vger.kernel.org # v4.5+ Signed-off-by:

[ Upstream commit 3b672623 ] The buck9 regulator of S2MPS11 PMIC had incorrect vsel_mask (0xff instead of 0x1f) thus reading entire register as buck9's voltage. This effectively caused regulator core to interpret values as higher voltages than they were and then to set real voltage much lower than intended. The buck9 provides power to other regulators, including LDO13 and LDO19 which supply the MMC2 (SD card). On Odroid XU3/XU4 the lower voltage caused SD card detection errors on Odroid XU3/XU4: mmc1: card never left busy state mmc1: error -110 whilst initialising SD card During driver probe the regulator core was checking whether initial voltage matches the constraints. With incorrect vsel_mask of 0xff and default value of 0x50, the core interpreted this as 5 V which is outside of constraints (3-3.775 V). Then the regulator core was adjusting the voltage to match the constraints. With incorrect vsel_mask this new voltage mapped to a vere low voltage in the driver. Signed-off-by:

[ Upstream commit 7f9be775 ] On s390 we only can enable hugepages if the underlying hardware/hypervisor also does support this. Common code now would assume this to be signaled by setting HPAGE_SHIFT to 0. But on s390, where we only support one hugepage size, there is a link between HPAGE_SHIFT and pageblock_order. So instead of setting HPAGE_SHIFT to 0, we will implement the check for the hardware capability. Signed-off-by:

[ Upstream commit b5dcec69 ] Allowing userptr bo which are basicly a list of page from some vma (so either anonymous page or file backed page) would lead to serious corruption of kernel structures and counters (because we overwrite the page->mapping field when mapping buffer). This will already block if the buffer was populated before anyone does try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm vm fault handler. So to be safe just add a check to verify_access() callback. Reviewed-by:

[ Upstream commit bfaddd9f ] This reverts commit e64c952e. ATPX is the ACPI method for controlling AMD PowerXpress laptops. There are flags to indicate which methods are supported. If the dGPU power down flag is not supported, the driver needs to implement the dGPU power down manually. We had previously always forced the driver to assume the ATPX dGPU power down was present, but this causes problems on boards where it is not, leading to GPU hangs when attempting to power down the dGPU. Manual dGPU power down is not currently supported in the Linux driver. Some laptops indicate that the ATPX dGPU power down method is not present, but it actually apparently is. I'm not sure if this is a bios bug and it should be set or if there is a reason it was unset and the method should not be used. This is not an issue on other OSes since both the ATPX and the manual driver power down methods are supported. This is apparently fairly widespread, so just revert for now. bugs: https://bugzilla.kernel.org/show_bug.cgi?id=115321 https://bugzilla.kernel.org/show_bug.cgi?id=116581 https://bugzilla.kernel.org/show_bug.cgi?id=116251 Cc: stable@vger.kernel.org Signed-off-by:

[ Upstream commit 6997e57d ] The REAL_LE feature entry in the ibm_pa_feature struct is missing an MMU feature value, meaning all the remaining elements initialise the wrong values. This means instead of checking for byte 5, bit 0, we check for byte 0, bit 0, and then we incorrectly set the CPU feature bit as well as MMU feature bit 1 and CPU user feature bits 0 and 2 (5). Checking byte 0 bit 0 (IBM numbering), means we're looking at the "Memory Management Unit (MMU)" feature - ie. does the CPU have an MMU. In practice that bit is set on all platforms which have the property. This means we set CPU_FTR_REAL_LE always. In practice that seems not to matter because all the modern cpus which have this property also implement REAL_LE, and we've never needed to disable it. We're also incorrectly setting MMU feature bit 1, which is: #define MMU_FTR_TYPE_8xx 0x00000002 Luckily the only place that looks for MMU_FTR_TYPE_8xx is in Book3E code, which can't run on the same cpus as scan_features(). So this also doesn't matter in practice. Finally in the CPU user feature mask, we're setting bits 0 and 2. Bit 2 is not currently used, and bit 0 is: #define PPC_FEATURE_PPC_LE 0x00000001 Which says the CPU supports the old style "PPC Little Endian" mode. Again this should be harmless in practice as no 64-bit CPUs implement that mode. Fix the code by adding the missing initialisation of the MMU feature. Also add a comment marking CPU user feature bit 2 (0x4) as reserved. It would be unsafe to start using it as old kernels incorrectly set it.

[ Upstream commit 8f815cdd ] A non-privileged user can create a netlink socket with the same port_id as used by an existing open nl80211 netlink socket (e.g. as used by a hostapd process) with a different protocol number. Closing this socket will then lead to the notification going to nl80211's socket release notification handler, and possibly cause an action such as removing a virtual interface. Fix this issue by checking that the netlink protocol is NETLINK_GENERIC. Since generic netlink has no notifier chain of its own, we can't fix the problem more generically.

[ Upstream commit e2726020 ] All existing users of NETLINK_URELEASE use it to clean up resources that were previously allocated to a socket via some command. As a result, no users require getting this notification for unbound sockets. Sending it for unbound sockets, however, is a problem because any user (including unprivileged users) can create a socket that uses the same ID as an existing socket. Binding this new socket will fail, but if the NETLINK_URELEASE notification is generated for such sockets, the users thereof will be tricked into thinking the socket that they allocated the resources for is closed. In the nl80211 case, this will cause destruction of virtual interfaces that still belong to an existing hostapd process; this is the case that Dmitry noticed. In the NFC case, it will cause a poll abort. In the case of netlink log/queue it will cause them to stop reporting events, as if NFULNL_CFG_CMD_UNBIND/NFQNL_CFG_CMD_UNBIND had been called. Fix this problem by checking that the socket is bound before generating the NETLINK_URELEASE notification. Cc: stable@vger.kernel.org Signed-off-by:
