[PATCH] PCI/cxgb4: Extend T3 PCI quirk to T4+ devices

by Ganesh Goudar

From: Casey Leedom <leedom(a)chelsio.com> We've run into a problem where our device is attached to a Virtual Machine and the use of the new pci_set_vpd_size() API doesn't help. The VM kernel has been informed that the accesses are okay, but all of the actual VPD Capability Accesses are trapped down into the KVM Hypervisor where it goes ahead and imposes the silent denials. The right idea is to follow the kernel.org commit 1c7de2b4ff88 ("PCI: Enable access to non-standard VPD for Chelsio devices (cxgb3)") which Alexey Kardashevskiy authored to establish a PCI Quirk for our T3-based adapters. This commit extends that PCI Quirk to cover Chelsio T4 devices and later. The advantage of this approach is that the VPD Size gets set early in the Base OS/Hypervisor Boot and doesn't require that the cxgb4 driver even be available in the Base OS/Hypervisor. Thus PF4 can be exported to a Virtual Machine and everything should work.

[PATCH] mm: hide a #warning for COMPILE_TEST

by Arnd Bergmann

We get a warning about some slow configurations in randconfig kernels: mm/memory.c:83:2: error: #warning Unfortunate NUMA and NUMA Balancing config, growing page-frame for last_cpupid. [-Werror=cpp] The warning is reasonable by itself, but gets in the way of randconfig build testing, so I'm hiding it whenever CONFIG_COMPILE_TEST is set. The warning was added in 2013 in commit 75980e97dacc ("mm: fold page->_last_nid into page->flags where possible").

[Linux-stable-mirror] [PATCH] ashmem: Fix lockdep issue during llseek

by Joel Fernandes

ashmem_mutex create a chain of dependencies like so: (1) mmap syscall -> mmap_sem -> (acquired) ashmem_mmap ashmem_mutex (try to acquire) (block) (2) llseek syscall -> ashmem_llseek -> ashmem_mutex -> (acquired) inode_lock -> inode->i_rwsem (try to acquire) (block) (3) getdents -> iterate_dir -> inode_lock -> inode->i_rwsem (acquired) copy_to_user -> mmap_sem (try to acquire) There is a lock ordering created between mmap_sem and inode->i_rwsem causing a lockdep splat [2] during a syzcaller test, this patch fixes the issue by unlocking the mutex earlier. Functionally that's Ok since we don't need to protect vfs_llseek.

[PATCH] [4.14 only backport] Bluetooth: BT_HCIUART now depends on SERIAL_DEV_BUS

by Arnd Bergmann

commit 05e89fb576f580ac95e7a5d00bdb34830b09671a upstream. It is no longer possible to build BT_HCIUART into the kernel when SERIAL_DEV_BUS is a loadable module, even if none of the SERIAL_DEV_BUS based implementations are selected: drivers/bluetooth/hci_ldisc.o: In function `hci_uart_set_flow_control': hci_ldisc.c:(.text+0xb40): undefined reference to `serdev_device_set_flow_control' hci_ldisc.c:(.text+0xb5c): undefined reference to `serdev_device_set_tiocm' This adds a dependency to avoid the broken configuration.
