2014-08-04x86/efi: Fix 3DNow optimization build failure in EFI stubMatt Fleming
Building a 32-bit kernel with CONFIG_X86_USE_3DNOW and CONFIG_EFI_STUB leads to the following build error, drivers/firmware/efi/libstub/lib.a(efi-stub-helper.o): In function `efi_relocate_kernel': efi-stub-helper.c:(.text+0xda5): undefined reference to `_mmx_memcpy' This is due to the fact that the EFI boot stub pulls in the 3DNow optimized versions of the memcpy() prototype from arch/x86/include/asm/string_32.h, even though the _mmx_memcpy() implementation isn't available in the EFI stub. For now, predicate CONFIG_EFI_STUB on !CONFIG_X86_USE_3DNOW. This is most definitely a temporary fix. A complete solution will involve selectively including kernel headers/symbols into the early-boot execution environment of the EFI boot stub, i.e. something analogous to the way that the _SETUP symbol is used. Previous attempts have been made to fix this kind of problem, though none seem to have ever been merged, http://lkml.kernel.org/r/20120329104822.GA17233@x1.osrc.amd.com Clearly, this problem has been around for a long time.

The fix is to set new_nodes[0] to NULL, since the out_nocoalesce path safely ignores NULL entries in the new_nodes array. This regression was introduced in 2d7f9531.

2014-08-04Drivers: net-next: hyperv: Increase the size of the sendbuf regionKY Srinivasan
Intel did some benchmarking on our network throughput when Linux on Hyper-V is as used as a gateway. This fix gave us almost a 1 Gbps additional throughput on about 5Gbps base throughput we hadi, prior to increasing the sendbuf size. The sendbuf mechanism is a copy based transport that we have which is clearly more optimal than the copy-free page flipping mechanism (for small packets). In the forwarding scenario, we deal only with MTU sized packets, and increasing the size of the senbuf area gave us the additional performance. For what it is worth, Windows guests on Hyper-V, I am told use similar sendbuf size as well. The exact value of sendbuf I think is less important than the fact that it needs to be larger than what Linux can allocate as physically contiguous memory. Thus the change over to allocating via vmalloc(). We currently allocate 16MB receive buffer and we use vmalloc there for allocation. Also the low level channel code has already been modified to deal with physically dis-contiguous memory in the ringbuffer setup. Based on experimentation Intel did, they say there was some improvement in throughput as the sendbuf size was increased up to 16MB and there was no effect on throughput beyond 16MB. Thus I have chosen 16MB here. Increasing the sendbuf value makes a material difference in small packet handling In this version of the patch, based on David's feedback, I have added additional details in the commit log.

Note that this branch also includes the new GICv3 driver (merged via a stable tag from Jason's irqchip tree), since there is a fix for older binutils on top. Changes include: - context tracking support (NO_HZ_FULL) which narrowly missed 3.16 - vDSO layout rework following Andy's work on x86 - TEXT_OFFSET fuzzing for bootloader testing - /proc/cpuinfo tidy-up - preliminary work to support 48-bit virtual addresses, but this is currently disabled until KVM has been ported to use it (the patches do, however, bring some nice clean-up) - boot-time CPU sanity checks (especially useful on heterogenous systems) - support for syscall auditing - support for CC_STACKPROTECTOR - defconfig updates" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (55 commits) arm64: add newline to I-cache policy string Revert "arm64: dmi: Add SMBIOS/DMI support" arm64: fpsimd: fix a typo in fpsimd_save_partial_state ENDPROC arm64: don't call break hooks for BRK exceptions from EL0 arm64: defconfig: enable devtmpfs mount option arm64: vdso: fix build error when switching from LE to BE arm64: defconfig: add virtio support for running as a kvm guest arm64: gicv3: Allow GICv3 compilation with older binutils arm64: fix soft lockup due to large tlb flush range arm64/crypto: fix makefile rule for aes-glue-%.o arm64: Do not invoke audit_syscall_* functions if !CONFIG_AUDIT_SYSCALL arm64: Fix barriers used for page table modifications arm64: Add support for 48-bit VA space with 64KB page configuration arm64: asm/pgtable.h pmd/pud definitions clean-up arm64: Determine the vmalloc/vmemmap space at build time based on VA_BITS arm64: Clean up the initial page table creation in head.S arm64: Remove asm/pgtable-*level-types.h files arm64: Remove asm/pgtable-*level-hwdef.h files arm64: Convert bool ARM64_x_LEVELS to int ARM64_PGTABLE_LEVELS arm64: mm: Implement 4 levels of translation tables ...

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "This pull request has a lot of work done. The main thing is the changes to the ftrace function callback infrastructure. It's introducing a way to allow different functions to call directly different trampolines instead of all calling the same "mcount" one. The only user of this for now is the function graph tracer, which always had a different trampoline, but the function tracer trampoline was called and did basically nothing, and then the function graph tracer trampoline was called. The difference now, is that the function graph tracer trampoline can be called directly if a function is only being traced by the function graph trampoline. If function tracing is also happening on the same function, the old way is still done. The accounting for this takes up more memory when function graph tracing is activated, as it needs to keep track of which functions it uses. I have a new way that wont take as much memory, but it's not ready yet for this merge window, and will have to wait for the next one. Another big change was the removal of the ftrace_start/stop() calls that were used by the suspend/resume code that stopped function tracing when entering into suspend and resume paths. The stop of ftrace was done because there was some function that would crash the system if one called smp_processor_id()! The stop/start was a big hammer to solve the issue at the time, which was when ftrace was first introduced into Linux. Now ftrace has better infrastructure to debug such issues, and I found the problem function and labeled it with "notrace" and function tracing can now safely be activated all the way down into the guts of suspend and resume Other changes include clean ups of uprobe code, clean up of the trace_seq() code, and other various small fixes and clean ups to ftrace and tracing" * tag 'trace-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (57 commits) ftrace: Add warning if tramp hash does not match nr_trampolines ftrace: Fix trampoline hash update check on rec->flags ring-buffer: Use rb_page_size() instead of open coded head_page size ftrace: Rename ftrace_ops field from trampolines to nr_trampolines tracing: Convert local function_graph functions to static ftrace: Do not copy old hash when resetting tracing: let user specify tracing_thresh after selecting function_graph ring-buffer: Always run per-cpu ring buffer resize with schedule_work_on() tracing: Remove function_trace_stop and HAVE_FUNCTION_TRACE_MCOUNT_TEST s390/ftrace: remove check of obsolete variable function_trace_stop arm64, ftrace: Remove check of obsolete variable function_trace_stop Blackfin: ftrace: Remove check of obsolete variable function_trace_stop metag: ftrace: Remove check of obsolete variable function_trace_stop microblaze: ftrace: Remove check of obsolete variable function_trace_stop MIPS: ftrace: Remove check of obsolete variable function_trace_stop parisc: ftrace: Remove check of obsolete variable function_trace_stop sh: ftrace: Remove check of obsolete variable function_trace_stop sparc64,ftrace: Remove check of obsolete variable function_trace_stop tile: ftrace: Remove check of obsolete variable function_trace_stop ftrace: x86: Remove check of obsolete variable function_trace_stop ...

The old way never worked properly as it assumed the bad config was a subset of the good config, and just found the config that would break the build. The new way does a diff of the bad config verses the good config and makes the similar until it finds that one config works and the other does not and reports the config that makes that difference.
