K 10 svn:author V 3 jhb K 8 svn:date V 27 2016-12-05T19:16:46.792529Z K 7 svn:log V 828 MFC 303688,303750,305166,305167: Centralize and rework page pod handling. Note that the TOE DDP code in 10 is different from 11 and later and had to be updated directly. 303688: cxgbe/t4_tom: Read the chip's DDP page sizes and save them in a per-adapter data structure. This replaces a global array with hardcoded page sizes. 303750: cxgbe/t4_tom: The page pod arena allocates from pod address space and not index space. The minimum valid allocation out of this arena is the size of a single page pod. 305166: cxgbe/t4_tom: Add general purpose routines to deal with page pod regions and allocations within them. Switch to these routines to manage the TOE DDP region. 305167: cxgbe/t4_tom: Two new routines to allocate and write page pods for a buffer in the kernel's address space.
