2015-09-20macvtap: fix TUNSETSNDBUF values > 64kMichael S. Tsirkin
Upon TUNSETSNDBUF, macvtap reads the requested sndbuf size into a local variable u. commit 39ec7de7092b ("macvtap: fix uninitialized access on TUNSETIFF") changed its type to u16 (which is the right thing to do for all other macvtap ioctls), breaking all values > 64k. The value of TUNSETSNDBUF is actually a signed 32 bit integer, so the right thing to do is to read it into an int. Cc: David S.

2015-09-21KVM: x86: trap AMD MSRs for the TSeg base and maskPaolo Bonzini
These have roughly the same purpose as the SMRR, which we do not need to implement in KVM. However, Linux accesses MSR_K8_TSEG_ADDR at boot, which causes problems when running a Xen dom0 under KVM. Just return 0, meaning that processor protection of SMRAM is not in effect.

This reverts commit 1298267b548a78840bd4b3e030993ff8747ca5e6. That commit claim that the Vitesse VSC8641 is compatible with Vitesse 82xx. But this is not true. It seems that all the registers used in Vitesse phy driver are not compatible between 8641 and 82xx. It does cause malfunction of the Ethernet on p1010rdb-pa board.

2015-09-20net: Fix behaviour of unreachable, blackhole and prohibit routesNikola Forró
Man page of ip-route(8) says following about route types: unreachable - these destinations are unreachable. Packets are dis‐ carded and the ICMP message host unreachable is generated. The local senders get an EHOSTUNREACH error. blackhole - these destinations are unreachable. Packets are dis‐ carded silently. The local senders get an EINVAL error. prohibit - these destinations are unreachable. Packets are discarded and the ICMP message communication administratively prohibited is generated. The local senders get an EACCES error. In the inet6 address family, this was correct, except the local senders got ENETUNREACH error instead of EHOSTUNREACH in case of unreachable route. In the inet address family, all three route types generated ICMP message net unreachable, and the local senders got ENETUNREACH error. In both address families all three route types now behave consistently with documentation. Signed-off-by: Nikola Forró <nforro@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-09-20NFSv4: Recovery of recalled read delegations is brokenTrond Myklebust
When a read delegation is being recalled, and we're reclaiming the cached opens, we need to make sure that we only reclaim read-only modes. A previous attempt to do this, relied on retrieving the delegation type from the nfs4_opendata structure. Unfortunately, as Kinglong pointed out, this field can only be set when performing reboot recovery. Furthermore, if we call nfs4_open_recover(), then we end up clobbering the state->flags for all modes that we're not recovering... The fix is to have the delegation recall code pass this information to the recovery call, and then refactor the recovery code so that nfs4_open_delegation_recall() does not need to call nfs4_open_recover().

Access to the kvm->buses (like with the kvm_io_bus_read() and -write() functions) has to be protected via the kvm->srcu lock. The kvmppc_h_logical_ci_load() and -store() functions are missing this lock so far, so let's add it there, too. This fixes the problem that the kernel reports "suspicious RCU usage" when lock debugging is enabled.

In guest_exit_cont we call kvmhv_commence_exit which expects the trap number as the argument. However r3 doesn't contain the trap number at this point and as a result we would be calling the function with a spurious trap number.

thunderbolt 2 controller The pci device ids listed in the thunderbolt driver are to restrictive, which prevents the driver from being loaded on recent Apple MacBooks using a thunderbolt 2 controller. In particular this prevented any hot-plugging functionality for thunderbolt based ethernet dongles (i.e. Apples thunderbolt gigabit ethernet broadcom tg3 based dongle Model A1433 EMC 2590). Changing the subvendor and subdevice to PCI_ANY_ID the thunderbolt driver loads and binds to the pci device 07:00.0 System peripheral: Intel Corporation Device 156c which is the thunderbolt 2 controller on the MacBookPro12,1. Successfully tested on MacBookPro12,1. With the patch the thunderbolt module gets now loaded on boot. And it provides hot-plugging support both for a cold-plugged and a warm-plugged ethernet dongle.

2015-09-19fs-writeback: unplug before cond_resched in writeback_sb_inodesChris Mason
Commit 505a666ee3fc ("writeback: plug writeback in wb_writeback() and writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes, which increases the merge rate when relatively contiguous small files are written by the filesystem. It helps both on flash and spindles. For an fs_mark workload creating 4K files in parallel across 8 drives, this commit improves performance ~9% more by unplugging before calling cond_resched(). cond_resched() doesn't trigger an implicit unplug, so explicitly getting the IO down to the device before scheduling reduces latencies for anyone waiting on clean pages. It also cuts down on how often we use kblockd to unplug, which means less work bouncing from one workqueue to another.

2015-09-19ASoC: fsl_ssi: Fix checking of dai format for AC97 modeAdam Thomson
Current code incorrectly treats dai format for AC97 as bit mask whereas it's actually an integer value. This causes DAI formats other than AC97 (e.g. DSP_B) to trigger AC97 related code, which is incorrect and breaks functionality. This patch fixes the code to correctly compare values to determine AC97 or not.

2015-09-19mm: fix type cast in __pfn_to_phys()Tyler Baker
The various definitions of __pfn_to_phys() have been consolidated to use a generic macro in include/asm-generic/memory_model.h. This hit mainline in the form of 012dcef3f058 "mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h". When the generic macro was implemented the type cast to phys_addr_t was dropped which caused boot regressions on ARM platforms with more than 4GB of memory and LPAE enabled. It was suggested to use PFN_PHYS() defined in include/linux/pfn.h as provides the correct logic and avoids further duplication.
