Building with gcc-4.6 results in this warning due to dmar_table_print_dmar_entry being inlined as in newer compiler versions: WARNING: vmlinux.o(.text+0x5c8bee): Section mismatch in reference from the function dmar_walk_remapping_entries() to the function .init.text:dmar_table_print_dmar_entry() The function dmar_walk_remapping_entries() references the function __init dmar_table_print_dmar_entry(). This is often because dmar_walk_remapping_entries lacks a __init annotation or the annotation of dmar_table_print_dmar_entry is wrong. This removes the __init annotation to avoid the warning.

This reverts commit bbdf0b2ff32a ("drm/i915/bxt: Disable device ready before shutdown command"). Disable device ready before shutdown command was added previously to avoid a split screen issue seen on dual link DSI panels. As of now, dual link is not supported and will need some rework in the upstream code. For single link DSI panels, the change is not required. This will cause failure in sending SHUTDOWN packet during disable. Hence reverting the change. Will handle the change as part of dual link enabling in upstream.

2017-09-18mtd: spi-nor: fix DMA unsafe buffer issue in spi_nor_read_sfdp()Cyrille Pitchen
spi_nor_read_sfdp() calls nor->read() to read the SFDP data. When the m25p80 driver is used (pretty common case), nor->read() is then implemented by the m25p80_read() function, which is likely to initialize a 'struct spi_transfer' from its buf argument before appending this structure inside the 'struct spi_message' argument of spi_sync(). Besides the SPI sub-system states that both .tx_buf and .rx_buf members of 'struct spi_transfer' must point into dma-safe memory. However, two of the three calls of spi_nor_read_sfdp() were given pointers to stack allocated memory as buf argument, hence not in a dma-safe area. Hopefully, the third and last call of spi_nor_read_sfdp() was already given a kmalloc'ed buffer argument, hence dma-safe. So this patch fixes this issue by introducing a spi_nor_read_sfdp_dma_unsafe() function which simply wraps the existing spi_nor_read_sfdp() function and uses some kmalloc'ed memory as a bounce buffer.

2017-09-18mtd: spi-nor: Check consistency of the memory size extracted from the SFDPBoris Brezillon
One field of the flash parameter table contains information about the flash device size. Most of the time the data extracted from this field is valid, but sometimes the BFPT section of the SFDP table is corrupted or invalid and this field is set to 0xffffffff, thus resulting in an integer overflow when setting params->size. Since NOR devices are anayway always smaller than 2^64 bytes, we can easily stop the BFPT parsing if the size reported in this table is invalid.

gcc-4.6 and older fail to inline integrator_clocksource_init, so they end up showing a harmless warning: WARNING: vmlinux.o(.text+0x4aa94c): Section mismatch in reference from the function integrator_clocksource_init() to the function .init.text:clocksource_mmio_init() The function integrator_clocksource_init() references the function __init clocksource_mmio_init().

2017-09-15net: smsc911x: Quieten netif during suspendGeert Uytterhoeven
If the network interface is kept running during suspend, the net core may call net_device_ops.ndo_start_xmit() while the Ethernet device is still suspended, which may lead to a system crash. E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is driven by a PM controlled clock. If the Ethernet registers are accessed while the clock is not running, the system will crash with an imprecise external abort. As this is a race condition with a small time window, it is not so easy to trigger at will. Using pm_test may increase your chances: # echo 0 > /sys/module/printk/parameters/console_suspend # echo platform > /sys/power/pm_test # echo mem > /sys/power/state To fix this, make sure the network interface is quietened during suspend.
