The most important one is probably, that dma-debug now warns if a dma-handle is not checked with dma_mapping_error by the device driver. This requires minor changes to some architectures which make use of dma-debug. Most of these changes have the respective Acks by the Arch-Maintainers. Besides that there are updates to the AMD IOMMU driver for refactor the IOMMU-Groups support and to make sure it does not trigger a hardware erratum. The OMAP changes (for which I pulled in a branch from Tony Lindgren's tree) have a conflict in linux-next with the arm-soc tree. The conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in the arm-soc tree. It is safe to delete the file too so solve the conflict. Similar changes are done in the arm-soc tree in the common clock framework migration. A missing hunk from the patch in the IOMMU tree will be submitted as a seperate patch when the merge-window is closed." * tag 'iommu-updates-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (29 commits) ARM: dma-mapping: support debug_dma_mapping_error ARM: OMAP4: hwmod data: ipu and dsp to use parent clocks instead of leaf clocks iommu/omap: Adapt to runtime pm iommu/omap: Migrate to hwmod framework iommu/omap: Keep mmu enabled when requested iommu/omap: Remove redundant clock handling on ISR iommu/amd: Remove obsolete comment iommu/amd: Don't use 512GB pages iommu/tegra: smmu: Move bus_set_iommu after probe for multi arch iommu/tegra: gart: Move bus_set_iommu after probe for multi arch iommu/tegra: smmu: Remove unnecessary PTC/TLB flush all tile: dma_debug: add debug_dma_mapping_error support sh: dma_debug: add debug_dma_mapping_error support powerpc: dma_debug: add debug_dma_mapping_error support mips: dma_debug: add debug_dma_mapping_error support microblaze: dma-mapping: support debug_dma_mapping_error ia64: dma_debug: add debug_dma_mapping_error support c6x: dma_debug: add debug_dma_mapping_error support ARM64: dma_debug: add debug_dma_mapping_error support intel-iommu: Prevent devices with RMRRs from being placed into SI Domain ...

For the 256-bit key cases, we run short on registers in the unrolled loops. So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that get clobbered. The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this. So if we have a mix of multi-block and single-block calls, the single-block unrolled 256-bit encrypt/decrypt can run with some of the key registers clobbered. Handle this by always explicitly loading those registers before using the non-unrolled 256-bit macro. This was discovered thanks to all of the new test cases added by Jussi Kivilinna.

Then, in commit de7d2b567d040e3b, Joe Perches added a warning for zero-length vmallocs, which can happen without kallsyms on modules with no init sections (eg. zlib_deflate). Fix this once and for all; the module code has to handle zero length anyway, so get it right at the caller and remove the now-gratuitous checks within the arch-specific module_alloc implementations.

I propose to add the get ability by using SO_ATTACH_FILTER in getsockopt. To be less irritating to eyes the SO_GET_FILTER alias to it is declared. This ability is required by checkpoint-restore project to be able to save full state of a socket. There are two issues with getting filter back. First, kernel modifies the sock_filter->code on filter load, thus in order to return the filter element back to user we have to decode it into user-visible constants. Fortunately the modification in question is interconvertible. Second, the BPF_S_ALU_DIV_K code modifies the command argument k to speed up the run-time division by doing kernel_k = reciprocal(user_k). Bad news is that different user_k may result in same kernel_k, so we can't get the original user_k back. Good news is that we don't have to do it. What we need to is calculate a user2_k so, that reciprocal(user2_k) == reciprocal(user_k) == kernel_k i.e. if it's re-loaded back the compiled again value will be exactly the same as it was. That said, the user2_k can be calculated like this user2_k = reciprocal(kernel_k) with an exception, that if kernel_k == 0, then user2_k == 1. The optlen argument is treated like this -- when zero, kernel returns the amount of sock_fprog elements in filter, otherwise it should be large enough for the sock_fprog array. changes since v1: * Declared SO_GET_FILTER in all arch headers * Added decode of vlan-tag codes Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.

Quite a bit of that stuff is actually shared with architecture trees; in such cases it's literally shared branch pulled by both, not a cherry-pick. A lot of ugliness and black magic is gone (-3KLoC total in this one): - kernel_thread()/kernel_execve()/sys_execve() redesign. We don't do syscalls from kernel anymore for either kernel_thread() or kernel_execve(): kernel_thread() is essentially clone(2) with callback run before we return to userland, the callbacks either never return or do successful do_execve() before returning. kernel_execve() is a wrapper for do_execve() - it doesn't need to do transition to user mode anymore. As a result kernel_thread() and kernel_execve() are arch-independent now - they live in kernel/fork.c and fs/exec.c resp. sys_execve() is also in fs/exec.c and it's completely architecture-independent. - daemonize() is gone, along with its parts in fs/*.c - struct pt_regs * is no longer passed to do_fork/copy_process/ copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump. - sys_fork()/sys_vfork()/sys_clone() unified; some architectures still need wrappers (ones with callee-saved registers not saved in pt_regs on syscall entry), but the main part of those suckers is in kernel/fork.c now." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: (113 commits) do_coredump(): get rid of pt_regs argument print_fatal_signal(): get rid of pt_regs argument ptrace_signal(): get rid of unused arguments get rid of ptrace_signal_deliver() arguments new helper: signal_pt_regs() unify default ptrace_signal_deliver flagday: kill pt_regs argument of do_fork() death to idle_regs() don't pass regs to copy_process() flagday: don't pass regs to copy_thread() bfin: switch to generic vfork, get rid of pointless wrappers xtensa: switch to generic clone() openrisc: switch to use of generic fork and clone unicore32: switch to generic clone(2) score: switch to generic fork/vfork/clone c6x: sanitize copy_thread(), get rid of clone(2) wrapper, switch to generic clone() take sys_fork/sys_vfork/sys_clone prototypes to linux/syscalls.h mn10300: switch to generic fork/vfork/clone h8300: switch to generic fork/vfork/clone tile: switch to generic clone() ...

This new method is now used in the default 'diff' output, making the sum of the 'baseline' column be 100%, eliminating blind spots. * libtraceevent fixes for compiler warnings trying to make perf it build on some distros, like fedora 14, 32-bit, some of the warnings really pointed to real bugs. * Add a browser for 'perf script' and make it available from the report and annotate browsers. It does filtering to find the scripts that handle events found in the perf.data file used. From Feng Tang * perf inject changes to allow showing where a task sleeps, from Andrew Vagin. * Makefile improvements from Namhyung Kim. * Add --pre and --post command hooks in 'stat', from Peter Zijlstra. * Don't stop synthesizing threads when one vanishes, this is for the existing threads when we start a tool like trace. * Use sched:sched_stat_runtime to provide a thread summary, this produces the same output as the 'trace summary' subcommand of tglx's original "trace" tool. * Support interrupted syscalls in 'trace' * Add an event duration column and filter in 'trace'. * There are references to the man pages in some tools, so try to build Documentation when installing, warning the user if that is not possible, from Borislav Petkov. * Give user better message if precise is not supported, from David Ahern. * Try to find cross-built objdump path by using the session environment information in the perf.data file header, from Irina Tirdea, original patch and idea by Namhyung Kim. * Diplays more output on features check for make V=1, so that one can figure out what is happening by looking at gcc output, etc. From Jiri Olsa. * Add on_exit implementation for systems without one, e.g. Android, from Bernhard Rosenkraenzer. * Only process events for vcpus of interest, helps handling large number of events, from David Ahern. * Cross compilation fixes for Android, from Irina Tirdea. * Add documentation on compiling for Android, from Irina Tirdea. * perf diff improvements from Jiri Olsa. * Target (task/user/cpu/syswide) handling improvements, from Namhyung Kim. * Add support in 'trace' for tracing workload given by command line, from Namhyung Kim. * ... and much more." * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (194 commits) uprobes: Use percpu_rw_semaphore to fix register/unregister vs dup_mmap() race perf evsel: Introduce is_group_member method perf powerpc: Use uapi/unistd.h to fix build error tools: Pass the target in descend tools: Honour the O= flag when tool build called from a higher Makefile tools: Define a Makefile function to do subdir processing perf ui: Always compile browser setup code perf ui: Add ui_progress__finish() perf ui gtk: Implement ui_progress functions perf ui: Introduce generic ui_progress helper perf ui tui: Move progress.c under ui/tui directory perf tools: Add basic event modifier sanity check perf tools: Omit group members from perf_evlist__disable/enable perf tools: Ensure single disable call per event in record comand perf tools: Fix 'disabled' attribute config for record command perf tools: Fix attributes for '{}' defined event groups perf tools: Use sscanf for parsing /proc/pid/maps perf tools: Add gtk.<command> config option for launching GTK browser perf tools: Fix compile error on NO_NEWT=1 build perf hists: Initialize all of he->stat with zeroes ...

Userspace tracers that also record TSCs are then on exactly the same time base as the kernel and events can be unambiguously interlaced. Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large timestamp values. v2: Move arch-specific bits out of generic code. v3: Rename "x86-tsc", cleanups v7: Generic arch bits in Kbuild.

Contained in here is a bunch more reworks of the tty port layer from Jiri and bugfixes from Alan, along with a number of other tty and serial driver updates by the various driver authors. Also, Jiri has been coerced^Wconvinced to be the co-maintainer of the TTY layer, which is much appreciated by me. All of these have been in the linux-next tree for a while. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>" Fixed up some trivial conflicts in the staging tree, due to the fwserial driver having come in both ways (but fixed up a bit in the serial tree), and the ioctl handling in the dgrp driver having been done slightly differently (staging tree got that one right, and removed both TIOCGSOFTCAR and TIOCSSOFTCAR). * tag 'tty-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (146 commits) staging: sb105x: fix potential NULL pointer dereference in mp_chars_in_buffer() staging/fwserial: Remove superfluous free staging/fwserial: Use WARN_ONCE when port table is corrupted staging/fwserial: Destruct embedded tty_port on teardown staging/fwserial: Fix build breakage when !CONFIG_BUG staging: fwserial: Add TTY-over-Firewire serial driver drivers/tty/serial/serial_core.c: clean up HIGH_BITS_OFFSET usage staging: dgrp: dgrp_tty.c: Audit the return values of get/put_user() staging: dgrp: dgrp_tty.c: Remove the TIOCSSOFTCAR ioctl handler from dgrp driver serial: ifx6x60: Add modem power off function in the platform reboot process serial: mxs-auart: unmap the scatter list before we copy the data serial: mxs-auart: disable the Receive Timeout Interrupt when DMA is enabled serial: max310x: Setup missing "can_sleep" field for GPIO tty/serial: fix ifx6x60.c declaration warning serial: samsung: add devicetree properties for non-Exynos SoCs serial: samsung: fix potential soft lockup during uart write tty: vt: Remove redundant null check before kfree. tty/8250 Add check for pci_ioremap_bar failure tty/8250 Add support for Commtech's Fastcom Async-335 and Fastcom Async-PCIe cards tty/8250 Add XR17D15x devices to the exar_handle_irq override ...
