2015-08-18x86/irq: Build correct vector mapping for multiple MSI interruptsJiang Liu
Alex Deucher, Mark Rustad and Alexander Holler reported a regression with the latest v4.2-rc4 kernel, which breaks some SATA controllers. With multi-MSI capable SATA controllers, only the first port works, all other ports time out when executing SATA commands. This happens because the first argument to assign_irq_vector_policy() is always the base linux irq number of the multi MSI interrupt block, so all subsequent vector assignments operate on the base linux irq number, so all MSI irqs are handled as the first irq number. Therefor the other MSI irqs of a device are never set up correctly and never fire. Add the loop iterator to the base irq number so all vectors are assigned correctly.

2015-08-18SCSI: Fix NULL pointer dereference in runtime PMAlan Stern
The routines in scsi_rpm.c assume that if a runtime-PM callback is invoked for a SCSI device, it can only mean that the device's driver has asked the block layer to handle the runtime power management (by calling blk_pm_runtime_init(), which among other things sets q->dev). However, this assumption turns out to be wrong for things like the ses driver. Normally ses devices are not allowed to do runtime PM, but userspace can override this setting. If this happens, the kernel gets a NULL pointer dereference when blk_post_runtime_resume() tries to use the uninitialized q->dev pointer. This patch fixes the problem by calling the block layer's runtime-PM routines only if the device's driver really does have a runtime-PM callback routine. Since ses doesn't define any such callbacks, the crash won't occur. This fixes Bugzilla #101371.

2015-08-18fnic: Use the local variable instead of I/O flag to acquire io_req_lock in ↵Hiral Shah
fnic_queuecommand() to avoid deadloack We added changes in fnic driver patch 1.6.0.16 to acquire io_req_lock in fnic_queuecommand() before issuing I/O so that io completion is serialized. But when releasing the lock we check for the I/O flag and this could be modified if IO abort occurs before I/O completion. In this case we wont release the lock and causes deadlock in some scenerios. Using the local variable to check the IO lock status will resolve the problem.

2015-08-18ARM: 8418/1: add boot image dependencies to not generate invalid imagesMasahiro Yamada
U-Boot is often used to boot the kernel on ARM boards, but uImage is not built by "make all", so we are often inclined to do "make all uImage" to generate DTBs, modules and uImage in a single command, but we should notice a pitfall behind it. In fact, "make all uImage" could generate an invalid uImage if it is run with the parallel option (-j). You can reproduce this problem with the following procedure: [1] First, build "all" and "uImage" separately. You will get a valid uImage $ git clean -f -x -d $ export CROSS_COMPILE=<your-tools-prefix> $ make -s -j8 ARCH=arm multi_v7_defconfig $ make -s -j8 ARCH=arm all $ make -j8 ARCH=arm UIMAGE_LOADADDR=0x80208000 uImage CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h make[1]: `include/generated/mach-types.h' is up to date.

Besides, "Kernel: arch/arm/boot/zImage is ready" is displayed twice, before and after the uImage log. The root cause of this is the race condition between zImage and uImage. Actually, uImage depends on zImage, but the dependency between the two is only described in arch/arm/boot/Makefile. Because arch/arm/boot/Makefile is not included from the top-level Makefile, it cannot know the dependency between zImage and uImage. Consequently, when we run make with the parallel option, Kbuild updates vmlinux first, and then two different threads descends into the arch/arm/boot/Makefile almost at the same time, one for updating zImage and the other for uImage. While one thread is re-generating zImage, the other also tries to update zImage before creating uImage on top of that. zImage is overwritten by the slower thread and then uImage is created based on the half-written zImage. This is the reason why "Kernel: arch/arm/boot/zImage is ready" is displayed twice, and a broken uImage is created. The same problem could happen on bootpImage. This commit adds dependencies among Image, zImage, uImage, and bootpImage to arch/arm/Makefile, which is included from the top-level Makefile.

The mmap semaphore should not be taken when page faults are disabled. Since pagefault_disable() no longer disables preemption, we now need to use faulthandler_disabled() in place of in_atomic().

2015-08-18MIPS: Fix LLVM build issue.Ralf Baechle
Matthew Fortune <Matthew.Fortune@imgtec.com> reports: The genex.S file appears to mix the case of a macro between its definition and use. A cut down example of this is below. The macro __build_clear_none has lower case 'build' but ends up being instantiated with upper case BUILD. Can this be fixed on master. It has been picked up by the LLVM integrated assembler which is currently case sensitive. We are likely to fix the assembler as well but the code is currently inconsistent in the kernel. .macro __build_clear_none .endm .macro __BUILD_HANDLER exception handler clear verbose ext .align 5 .globl handle_\exception; .align 2; .type handle_\exception, @function; .ent handle_\exception, 0; handle_\exception: .frame $29, 184, $29 .set noat .globl handle_\exception\ext; .type handle_\exception\ext, @function; handle_\exception\ext: __BUILD_clear_\clear .endm .macro BUILD_HANDLER exception handler clear verbose __BUILD_HANDLER \exception \handler \clear \verbose _int .endm BUILD_HANDLER ftlb ftlb none silent Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Reported-by: Matthew Fortune <Matthew.Fortune@imgtec.com>

This reverts commit: 2c7577a75837 ("sched/x86_64: Don't save flags on context switch") It was a nice speedup. It's also not quite correct: SYSENTER enables interrupts too early. We can re-add this optimization once the SYSENTER code is beaten into shape, which should happen in 4.3 or 4.4.

2015-08-17ASoC: topology: Add Kconfig option for topologyMark Brown
Allow the topology code to be compiled out so that users who don't need topology don't need to havve the code compiled in, saving them some memory. Some more configuration could be added to remove some of the hooks into the core data structures but that is probably best done with some refactoring to use functions to do the updates of the data structures rather than ifdefing in the code as we'd need to do at the minute.

2015-08-18crypto: caam - add support for LS1021AHoria Geant?
LS1021A is a QorIQ SoC having little endian CAAM. There are a few differences b/w QorIQ and i.MX from CAAM perspective: 1. i.MX platforms are somewhat special wrt. 64-bit registers: -big endian format at 64-bit level: MSW at address+0 and LSW at address+4 -little endian format at 32-bit level (within MSW and LSW) and thus need special handling. 2. No CCM (clock controller module) for QorIQ. No CAAM clocks to enable / disable. A new Kconfig option - CRYPTO_DEV_FSL_CAAM_LE - is added to indicate CAAM is little endian (*). It is hidden from the user (to avoid misconfiguration); when adding support for a new platform with LE CAAM, either the Kconfig needs to be updated or the corresponding defconfig needs to indicate that CAAM is LE. (*) Using a DT property to provide CAAM endianness would not allow for the ifdeffery. In order to keep changes to a minimum, the following changes are postponed: -endianness fix of the last word in the S/G (rsvd2, bpid, offset), fields are always 0 anyway; -S/G format fix for i.MX7 (yes, i.MX7 support was not added yet, but still...)

2015-08-18crypto: vmx - Fixing GHASH Key issue on little endianLeonidas Da Silva Barbosa
GHASH table algorithm is using a big endian key. In little endian machines key will be LE ordered. After a lxvd2x instruction key is loaded as it is, LE/BE order, in first case it'll generate a wrong table resulting in wrong hashes from the algorithm. Bug affects only LE machines. In order to fix it we do a swap for loaded key. Cc: stable@vger.kernel.org Signed-off-by: Leonidas S Barbosa <leosilva@linux.vnet.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
