2016-01-06net: Add eth_platform_get_mac_address() helper.David S. Miller
A repeating pattern in drivers has become to use OF node information and, if not found, platform specific host information to extract the ethernet address for a given device. Currently this is done with a call to of_get_mac_address() and then some ifdef'd stuff for SPARC. Consolidate this into a portable routine, and provide the arch_get_platform_mac_address() weak function hook for all architectures to implement if they want. Signed-off-by: David S.

2016-01-06storvsc: Tighten up the interrupt pathK. Y. Srinivasan
On the interrupt path, we repeatedly establish the pointer to the storvsc_device. While the compiler does inline get_in_stor_device() (and other static functions) in the call chain in the interrupt path, the compiler is repeatedly inlining the call to get_in_stor_device() each time it is invoked. The return value of get_in_stor_device() can be cached in the interrupt path since there is higher level serialization in place to ensure correct handling when the module unload races with the processing of an incoming message from the host. Optimize this code path by caching the pointer to storvsc_device and passing it as an argument. Signed-off-by: K. Y.

2016-01-06ethernet/atheros/alx: sanitize buffer sizing and paddingJarod Wilson
This is based on the work done by Przemek Rudy in bug 70761 at bugzilla.kernel.org, but with some work done to disentagle and clarify things a bit. Similar to Przemek's work and other drivers, we're adding a padding of 16 here, but we're also disentangling mtu size calculations from max buffer size calculations a bit, and adding ETH_HLEN to the value written into ALX_MTU. Hopefully, with a bit more consistency and clarity, things behave better here. Sadly, I can only test in my alx-driven E2200, which worked just fine before this patch. In comment #58 of bug 70761, Eugene A. Shatokhin reports that this patch does help considerably for a ROSA Linux user of his with an AR8162 network adapter when patched into a 4.1.x-based kernel, with several days of normal operation where wired network previously wasn't usable without setting MTU to 9000 as a work-around.

2016-01-06ARM: OMAP2+: Fix onenand rate detection to avoid filesystem corruptionTony Lindgren
Commit 63aa945b1013 ("memory: omap-gpmc: Add Kconfig option for debug") unified the GPMC debug for the SoCs with GPMC. The commit also left out the option for HWMOD_INIT_NO_RESET as we now require proper timings for GPMC to be able to remap GPMC devices out of address 0. Unfortunately on Nokia N900, onenand now only partially works with the device tree provided timings. It works enough to get detected but the clock rate supported by the onenand chip gets misdetected. This in turn causes the GPMC timings to be miscalculated and this leads into file system corruption on N900. Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync write. This is needed also for async timings when we write to onenand with omap2_onenand_set_async_mode(). Without sync write bit set, the async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff. Let's exit with an error if onenand rate is not detected. And let's remove the extra call to omap2_onenand_set_async_mode() as we only need to do this once at the end of omap2_onenand_setup_async().

2016-01-06arm64: head.S: use memset to clear BSSMark Rutland
Currently we use an open-coded memzero to clear the BSS. As it is a trivial implementation, it is sub-optimal. Our optimised memset doesn't use the stack, is position-independent, and for the memzero case can use of DC ZVA to clear large blocks efficiently. In __mmap_switched the MMU is on and there are no live caller-saved registers, so we can safely call an uninstrumented memset. This patch changes __mmap_switched to use memset when clearing the BSS. We use the __pi_memset alias so as to avoid any instrumentation in all kernel configurations.

2016-01-06arm64: entry: remove pointless SPSR mode checkMark Rutland
In work_pending, we may skip work if the stacked SPSR value represents anything other than an EL0 context. We then immediately invoke the kernel_exit 0 macro as part of ret_to_user, assuming a return to EL0. This is somewhat confusing. We use work_pending as part of the ret_to_user/ret_fast_syscall state machine. We only use ret_fast_syscall in the return from an SVC issued from EL0. We use ret_to_user for return from EL0 exception handlers and also for return from ret_from_fork in the case the task was not a kernel thread (i.e. it is a user task). Thus in all cases the stacked SPSR value must represent an EL0 context, and the check is redundant. This patch removes it, along with the now unused no_work_pending label.

2016-01-06Bluetooth: btmrvl: don't send data to firmware while processing suspendChin-Ran Lo
Usually when driver sends data to firmware it receives TX_DONE (DN_LD_HOST_INT_STATUS) interrupt from firmware right away. It's also observed that some times the fireware could delay sending DN_LD_HOST_INT_STATUS interrupt. If driver sends data to firmware during suspend processing and the TX_DONE interrupt is delayed, it may come back at wrong time when SDIO host driver is in the middle of suspending. Block any data from stack while suspending. Also skip sending data that are already in driver tx_queue. Don't purge the skb queue on suspend to avoid intermittent music after system resumes from S3.
