[PATCH 3/3] USB: musb: dsps: propagate device-tree node

To be able to use DSPS-based controllers with device-tree descriptions of the USB topology, we need to associate the glue device's device-tree node with the child controller device. Note that this can also be used to eventually let USB core manage generic phys. Also note that the other glue drive

[PATCH 2/3] USB: musb: host: prevent core phy initialisation

[PATCH] drm/vmwgfx: Fix scatterlist unmapping

dma_unmap_sg() should be called with the same number of entries originally passed to dma_map_sg(), not the number it returned, which may be fewer.

[PATCH 5/6] Pmalloc selftest

[PATCH] virtio_balloon: add array of stat names

Jason Wang points out that it's vary hard for users to build an array of stat names. The naive thing is to use VIRTIO_BALLOON_S_NR but that breaks if we add more stats. Let's add an array of reasonably readable names. Fixes: 6c64fe7f2 ("virtio_balloon: export hugetlb page allocation counts") Cc:

[PATCH 3/6] Protectable Memory

The MMU available in many systems running Linux can often provide R/O protection to the memory pages it handles. However, the MMU-based protection works efficiently only when said pages contain exclusively data that will not need further modifications. Statically allocated variables can be segreg

[RFC PATCH v22 0/6] mm: security: ro protection for dynamic data

This patch-set introduces the possibility of protecting memory that has been allocated dynamically. The memory is managed in pools: when a memory pool is protected, all the memory that is currently part of it, will become R/O. A R/O pool can be expanded (adding more protectable memory). It can al

The vmap_area structure has a field of type struct llist_node, named purge_list and is used when performing lazy purge of the area. Such field is left unused during the actual utilization of the structure. This patch renames the field to a more generic "area_list", to allow for utilization outsid

When a page is used for virtual memory, it is often necessary to obtain a handler to the corresponding vm_struct, which refers to the virtually continuous area generated when invoking vmalloc. The struct page has a "mapping" field, which can be re-used, to store a pointer to the parent area. This
