[PATCH RFCv1 3/5] virtio-mem: try to merge "System RAM (virtio_mem)" resources
virtio-mem adds memory in memory block granularity, to be able to remove it in the same granularity again later, and to grow slowly on demand. This, however, results in quite a lot of resources when adding a lot of memory. Resources are effectively stored in a list-based tree. Having a lot of resources not only wastes memory, it also makes traversing that tree more expensive, and makes /proc/iomem

[PATCH RFCv1 0/5] mm/memory_hotplug: selective merging of memory resources
Some add_memory*() users add memory in small, contiguous memory blocks. Examples include virtio-mem, hyper-v balloon, and the XEN balloon. This can quickly result in a lot of memory resources, whereby the actual resource boundaries are not of interest (e.g., it might be relevant for DIMMs, exposed via /proc/iomem to user space). We really want to merge added resources in this scenario where

[RFC PATCH v2] cover: armv7: celt_pitch_xcorr: Introduce ARM neon intrinsics
From: Viswanath Puttagunta <viswanath.puttagunta at linaro.org> Hi, Optimizes celt_pitch_xcorr for floating point. Changes from RFCv1: - Rebased on top of commit aad281878: Fix celt_pitch_xcorr_c signature. which got rid of ugly code around CELT_PITCH_XCORR_IMPL passing of "arch" parameter. - Unified with --enable-intrinsics used by x86 - Modified algorithm to be more in-line with algorithm in celt_pitch_xcorr_a...

[PATCH 0/5]
...e that has its own DMA translation logic, it can efficiently structure the memory mapping to get best performance. Note, this only impacts the devices that want its own DMA translation (less times of set_map() call). For other type of devices, there's no changes in the behaviour. Changes from RFCV1: - tweak the comments per Michael's request Jason Wang (5): vhost-vdpa: refine ioctl pre-processing vhost: generialize backend features setting/getting vhost-vdpa: support get/set backend features vhost-vdpa: support IOTLB batching hints vdpasim: support batch updating drivers/vdp...

[RFC PATCHv2] Intrinsics/RTCD related fixes. Mostly x86.
From: Jonathan Lennox <jonathan at vidyo.com> * Makes ?enable-intrinsics work with clang and other non-GCC compilers * Enables RTCD for the floating-point-mode SSE code in Celt. * Disables use of RTCD in cases where the compiler targets an instruction set by default. * Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk when Opus is built in floating-point mode, not
