[PATCH v4 1/9] mtd: sharpslpart: add sharpslpart MTD partition parser

The Sharp SL Series (Zaurus) PXA handhelds have 16/64/128M of NAND flash and share the same layout of the first 7M partition, managed by Sharp FTL. The purpose of this self-contained patch is to add a common parser and remove the hardcoded sizes in the board files (these devices are not yet

[PATCH 12/15] mm/migrate: new memory migration helper for use with device memory v4

This patch add a new memory migration helpers, which migrate memory backing a range of virtual address of a process to different memory (which can be allocated through special allocator). It differs from numa migration by working on a range of virtual address and thus by doing migration in chunk
