The driver is using now solely its own request queue.
- tape->next_stage is always NULL so it is safe to remove
all code depending on tape->next_stage != NULL
- this patch removes the last place which sets
IDETAPE_FLAG_PIPELINE_ACTIVE in tape->flags

The computation of the block offset of the the tape position (MTIOCPOS,

Since we don't do pipeline read-ahead anymore, we don't have to look for

In order to do away with queueing read requests on the pipeline, several things
have to be done:
1. Do not allocate additional pipeline stages in idetape_init_read() until
(tape->nr_stages < max_stages) and do only read operation preparations. As a
collateral result, idetape_add_stage_tail() becomes unused so remove it.
2. Queue the read request's buffer directly thru idetape_queue_rw_tail().
3. Remove now unused idetape_kmalloc_stage() and idetape_switch_buffers().

Pipeline handling calculations in idetape_calculate_speeds() can
go since they do not have any effect on other functionality besides:
1. info is only being exported through /proc as a read-only item
(controlled_pipeline_head_speed, uncontrolled_pipeline_head_speed)
2. used in idetape_restart_speed_control() which, in turn, is unrelated to
other code
3. used only for pipeline frames number accounting (tape->pipeline_head),
also unused elsewhere.
4.some variables are:
only written to: tape->buffer_head;
unused: tape->tape_head, tape->last_tape_head

typical case: four sockets system, every node has 4g ram, and we are using:
memmap=10g$4g
to mask out memory on node1 and node2
when numa is enabled, early_node_mem is used to get node_data and node_bootmap.
if it can not get memory from the same node with find_e820_area(), it will
use alloc_bootmem to get buff from previous nodes.
so check it and print out some info about it.
need to move early_res_to_bootmem into every setup_node_bootmem.
and it takes range that node has. otherwise alloc_bootmem could return addr
that reserved early.
depends on "mm: make reserve_bootmem can crossed the nodes".

"mm: make reserve_bootmem can crossed the nodes" provides new
reserve_bootmem(), let reserve_bootmem_generic() use that.
reserve_bootmem_generic() is used to reserve initramdisk, so this way
we can make sure even when bootloader or kexec load ranges cross the
node memory boundaries, reserve_bootmem still works.

Make the nodes other than node 0 use bdata->last_success for fast

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.

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 ;-)

* Make ide_hwif_setup_dma() return an error value.
* Pass 'const struct ide_port_info *d' instead of 'unsigned long dmabase'
to ->init_dma method and make it return an error value.
* Rename ide_get_or_set_dma_base() to ide_pci_dma_base(),
change ordering of its arguments and then export it.
* Export ide_pci_set_master().
* Do complete DMA setup inside ->init_dma method and update ->init_dma
users accordingly.
* Sanitize code for DMA setup in ide_init_port().
v2:
* Fix for CONFIG_BLK_DEV_IDEDMA_PCI=n configs
(from Jiri Slaby <jirislaby@gmail.com>):
Fix following compiler warning by returning EINVAL:

Always use "fast" MWDMA support and remove dma_{black,white}_list
(they were based on completely bogus ->ide_dma_check implementation
which didn't set neither the host controller timings nor the device
for the desired transfer mode).
