commit f466ae66 upstream. It is now legal to invoke synchronize_sched() at early boot, which causes Tiny RCU's synchronize_sched() to emit spurious splats. This commit therefore removes the cond_resched() from Tiny RCU's synchronize_sched(). Fixes: 8b355e3b ("rcu: Drive expedited grace periods from workqueue") Signed-off-by:

commit 89e9f7bc upstream. Martin reported that the Supermicro X8DTH-i/6/iF/6F advertises incorrect host bridge windows via _CRS: pci_root PNP0A08:00: host bridge window [io 0xf000-0xffff] pci_root PNP0A08:01: host bridge window [io 0xf000-0xffff] Both bridges advertise the 0xf000-0xffff window, which cannot be correct. Work around this by ignoring _CRS on this system. The downside is that we may not assign resources correctly to hot-added PCI devices (if they are possible on this system).

commit 621cb4e7 upstream. This patch modifies the build dependencies on the jitdump support in perf. As it stands jitdump was wrongfully made dependent 100% on using DWARF. However, the dwarf dependency, only exist if generating the source line table in genelf_debug.c. The rest of the support does not need DWARF. This patch removes the dependency on DWARF for the entire jitdump support. It keeps it only for the genelf_debug.c support. Signed-off-by:

commit ed6c166c upstream. Fixes a perf diff regression issue which was introduced by commit 5baecbcd ("perf symbols: we can now read separate debug-info files based on a build ID") The binary name could be same when perf diff different binaries. Build id is used to distinguish between them. However, the previous patch assumes the same binary name has same build id. So it overwrites the build id according to the binary name, regardless of whether the build id is set or not. Check the has_build_id in dso__load. If the build id is already set, use it.

commit c482af64 upstream. For non-special QPs, the port value becomes non-zero only at the RESET-to-INIT transition. If the QP has not undergone that transition, its port number value is still zero. If such a QP is destroyed before being moved out of the RESET state, subtracting one from the qp port number results in a negative value. Using that negative value as an index into the qp1_proxy array results in an out-of-bounds array reference. Fix this by testing that the QP type is one that uses qp1_proxy before using the port number. For special QPs of all types, the port number is specified at QP creation time.

commit afd02cd3 upstream. When enabling many VFs, the total amount of DMA mappings increase significantly. This causes DMA allocations to take a lot of time since they are serialized in the kernel. As a result the driver enters into fatal condition due to timeout and the system hangs. To recover from this we disable MR cache for VFs. PFs will still have a full cache and VFs cache can be manipulated as usual after driver load. Fixes: e126ba97 ('mlx5: Add driver for Mellanox Connect-IB adapters') Signed-off-by:

commit 5d7400c4 upstream. Always stating PIN_CONFIG_BIAS_DISABLE is supported gives untrue output when examining /sys/kernel/debug/pinctrl/e6060000.pfc/pinconf-pins if the operation get_bias() is implemented but the pin is not handled by the get_bias() implementation. In that case the output will state that "input bias disabled" indicating that this pin has bias control support. Make support for PIN_CONFIG_BIAS_DISABLE depend on that the pin either supports SH_PFC_PIN_CFG_PULL_UP or SH_PFC_PIN_CFG_PULL_DOWN. This also solves the issue where SoC specific implementations print error messages if their particular implementation of {set,get}_bias() is called with a pin it does not know about. Signed-off-by:

commit 20156ce2 upstream. The find_num_contig() will return 1 when the pmd is not present. It will cause a kernel dead loop in the following scenaro: 1.) pmd entry is not present. 2.) the page fault occurs: ... hugetlb_fault() --> hugetlb_no_page() --> set_huge_pte_at() 3.) set_huge_pte_at() will only set the first PMD entry, since the find_num_contig just return 1 in this case. So the PMD entries are all empty except the first one. 4.) when kernel accesses the address mapped by the second PMD entry, a new page fault occurs: ... hugetlb_fault() --> huge_ptep_set_access_flags() The second PMD entry is still empty now. 5.) When the kernel returns, the access will cause a page fault again. The kernel will run like the "4)" above. We will see a dead loop since here. The dead loop is caught in the 32M hugetlb page (2M PMD + Contiguous bit). This patch removes wrong pmd check, and fixes this dead loop. This patch also removes the redundant checks for PGD/PUD in the find_num_contig(). Acked-by:

commit d4791db5 upstream. Whenever a PE is initialised in powernv, opal_pci_eeh_freeze_clear() is called. This is to remove any existing freeze, and has no negative side effects if the PE is already in an unfrozen state. On PHB backends that don't support this operation and return OPAL_UNSUPPORTED, this creates a scary and misleading warning message. Skip the warning message on init if OPAL_UNSUPPORTED is returned.
