Today powerpc64 uses a set of pgtable_caches while powerpc32 uses standard pages when using 4k pages and a single pgtable_cache if using other size pages. In preparation of implementing huge pages on the 8xx, this patch replaces the specific powerpc32 handling by the 64 bits approach. This is done by: * moving 64 bits pgtable_cache_add() and pgtable_cache_init() in a new file called init-common.c * modifying pgtable_cache_init() to also handle the case without PMD * removing the 32 bits version of pgtable_cache_add() and pgtable_cache_init() * copying related header contents from 64 bits into both the book3s/32 and nohash/32 header files On the 8xx, the following cache sizes will be used: * 4k pages mode: - PGT_CACHE(10) for PGD - PGT_CACHE(3) for 512k hugepage tables * 16k pages mode: - PGT_CACHE(6) for PGD - PGT_CACHE(7) for 512k hugepage tables - PGT_CACHE(3) for 8M hugepage tables Signed-off-by: NChristophe Leroy <christophe.leroy@c-s.fr> Reviewed-by: NAneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: NScott Wood <oss@buserror.net>

1. qm_mcc_querywq layout not used for now, so drop it; 2. queryfq, queryfq_np and alterfq are used only for accesses to the 'fqid' field, so replace these with a generic 'fq' layout. As a consequence, 'querycgr' turns into 'cgr' following the same reasoning above and for consistent naming.

The qman portals are platform devices themselves, so they should handle dma mappings. Creating a dummy platform device in order to support dma mapping operations is not justified (and not portable).

qman_query_fq*() may return other error codes apart from -ERANGE, in which cases the error handling done by the resource cleanup callers would be wrong. The patch fixes the handling of those cases, and cleans up related code inside the resource cleanup & release handlers (i.e. replace hardcoded fqid value with corresponding define).

Version 3.00 of the ISA states that the PATS (partition table size) field of the PTCR (partition table control register) and the PRTS (process table size) field of the partition table entry must both be less than or equal to 24. However the actual size of the partition and process tables is equal to 2 to the power of 12 plus the PATS and PRTS fields, respectively. This means that the max allowable size of each of these tables is 2^36 or 64GB for both. Thus when checking the size shift for each we should be checking for values of greater than 36 instead of the current check for shifts larger than 24 and 23.
