Till now block layer allowed two separate modes of request execution.
A request is always acquired from the request queue via
elv_next_request(). After that, drivers are free to either dequeue it
or process it without dequeueing. Dequeue allows elv_next_request()
to return the next request so that multiple requests can be in flight.
Executing requests without dequeueing has its merits mostly in
allowing drivers for simpler devices which can't do sg to deal with
segments only without considering request boundary. However, the
benefit this brings is dubious and declining while the cost of the API
ambiguity is increasing. Segment based drivers are usually for very
old or limited devices and as converting to dequeueing model isn't
difficult, it doesn't justify the API overhead it puts on block layer
and its more modern users.
Previous patches converted all block low level drivers to dequeueing
model. This patch completes the API transition by...
* renaming elv_next_request() to blk_peek_request()
* renaming blkdev_dequeue_request() to blk_start_request()
* adding blk_fetch_request() which is combination of peek and start
* disallowing completion of queued (not started) requests
* applying new API to all LLDs
Renamings are for consistency and to break out of tree code so that
it's apparent that out of tree drivers need updating.
[ Impact: block request issue API cleanup, no functional change ]

Card detection interrupts should be handled separately as they should
not be enabled before mmc_add_host() returns and should be disabled
before calling mmc_remove_host(). The same is for suspend and resume
routines.
sdhci_init() no longer enables card-detection irqs. Instead, two new
functions implemented: sdhci_enable_card_detection() and
sdhci_disable_card_detection().
New sdhci_reinit() call implemented to behave the same way as the old
sdhci_init().
Also, this patch implements and uses few new helpers to manage IRQs in
a more conveinient way, that is:
- sdhci_clear_set_irqs()
- sdhci_unmask_irqs()
- sdhci_mask_irqs()
- SDHCI_INT_ALL_MASK constant
sdhci_enable_sdio_irq() converted to these new helpers, plus the
helpers will be used by the subsequent patches.

Currently the SDHCI driver works with PCI accessors (write{l,b,w} and
read{l,b,w}).
With this patch drivers may change memory accessors, so that we can
support hosts with "weird" IO memory access requirments.
For example, in "FSL eSDHC" SDHCI hardware all registers are 32 bit
width, with big-endian addressing. That is, readb(0x2f) should turn
into readb(0x2c), and readw(0x2c) should be translated to
le16_to_cpu(readw(0x2e)).

Some MMC commands result in the card becoming busy after
the response is received. This needs to be specified
for the omap_hsmmc host controller, which is what this
patch does. However, the effect is that some commands
with no data will cause a Transfer Complete (TC) interrupt
in addition to the Command Complete (CC) interrupt.
In order to deal with that, the irq handler has needed
a few changes also.
The benefit of this change is that the omap_hsmmc host
controller driver now waits for the TC interrupt while
the card is busy, so the mmc_block driver needs to poll
the card status just once instead of repeatedly.
i.e. the net result is more sleep and less cpu.
The command sequence for open-ended multi-block write
with DMA is now:
Issue write command CMD25
Receive CC interrupt
Data is sent
Receive TC interrupt (DMA is done)
Issue stop command CMD12
Receive CC interrupt
Card is busy
Receive TC interrupt
Card is now ready for next transfer
