ad09315cad mm: fix alloc_bootmem_core to use fast searching for all nodes
Make the nodes other than node 0 use bdata->last_success for fast
search too.

We need to use __alloc_bootmem_core() for vmemmap allocation for other
nodes when numa and sparsemem/vmemmap are enabled.

Also, make fail_block path increase i with incr only after ALIGN
to avoid extra increase when size is larger than align.

e123dd3f0e mm: make mem_map allocation continuous
vmemmap allocation currently has this layout:

 [ffffe20000000000-ffffe200001fffff] PMD ->ffff810001400000 on node 0
 [ffffe20000200000-ffffe200003fffff] PMD ->ffff810001800000 on node 0
 [ffffe20000400000-ffffe200005fffff] PMD ->ffff810001c00000 on node 0
 [ffffe20000600000-ffffe200007fffff] PMD ->ffff810002000000 on node 0
 [ffffe20000800000-ffffe200009fffff] PMD ->ffff810002400000 on node 0
...

note that there is a 2M hole between them - not optimal.

the root cause is that usemap (24 bytes) will be allocated after every 2M
mem_map, and it will push next vmemmap (2M) to the next (2M) alignment.

solution: try to allocate the mem_map continously.

after the patch, we get:

 [ffffe20000000000-ffffe200001fffff] PMD ->ffff810001400000 on node 0
 [ffffe20000200000-ffffe200003fffff] PMD ->ffff810001600000 on node 0
 [ffffe20000400000-ffffe200005fffff] PMD ->ffff810001800000 on node 0
 [ffffe20000600000-ffffe200007fffff] PMD ->ffff810001a00000 on node 0
 [ffffe20000800000-ffffe200009fffff] PMD ->ffff810001c00000 on node 0
...

which is the ideal layout.

and usemap will share a page because of they are allocated continuously too:

sparse_early_usemap_alloc: usemap = ffff810024e00000 size = 24
sparse_early_usemap_alloc: usemap = ffff810024e00080 size = 24
sparse_early_usemap_alloc: usemap = ffff810024e00100 size = 24
sparse_early_usemap_alloc: usemap = ffff810024e00180 size = 24
...

so we make the bootmem allocation more compact and use less memory
for usemap => mission accomplished ;-)

While at it:

* Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods.

* Drop "ide_" "infixes" from DMA methods.

* au1xxx-ide.c:
  - use auide_dma_{test_irq,end}() directly in auide_dma_timeout()

* pdc202xx_old.c:
  - drop "old_" "infixes" from DMA methods

* siimage.c:
  - add siimage_dma_test_irq() helper
  - print SATA warning in siimage_init_one()

* Remove no longer needed ->init_hwif implementations.

v2:
* Changes based on review from Sergei:
  - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/
  - s/drive->hwif/hwif/ in idefloppy_pc_intr().
  - fix patch description w.r.t. au1xxx-ide changes
  - fix au1xxx-ide build
  - fix naming for cmd64*_dma_ops
  - drop "ide_" and "old_" infixes
  - s/hpt3xxx_dma_ops/hpt37x_dma_ops/
  - s/hpt370x_dma_ops/hpt370_dma_ops/
  - use correct DMA ops for HPT302/N, HPT371/N and HPT374

v3:
* Two bugs slipped in v2 (noticed by Sergei):
  - use correct DMA ops for HPT374 (for real this time)
  - handle HPT370/HPT370A properly
