now it is possible to add missing checks to ide_tune_dma() and remove

pdc202xx_old: rewrite mode programming code (v2)
This patch is based on the documentation (I would like to thank Promise
for it) and also partially on the older vendor driver.
Rewrite mode programming code:
* disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled
even if both devices on the channel are not DMA capable and after reset
* enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset()
as they need to be setup correctly also for PIO only devices, plus IORDY
wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for
ATAPI devices
* remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma()
(driver sets ->autotune to 1 so PIO modes are always programmed => lower
nibble of register A never equals 4 => "chipset_is_set" is always true)
* enable PIO mode programming for all ATAPI devices
(it was limited to ->media == ide_cdrom devices)
* remove extra reads of registers A/B/C, don't read register D et all
* do clearing / programming of registers A/B/C in one go
(gets rid of extra PCI config space read/write cycle)
* set initial values of drive_conf/AP/BP/CP variables to zero
(paranoia for the case when PCI reads fail)
* remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen
(ide_rate_filter() takes care of it)
* fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)
* fix bitmasks for clearing bits of register B:
- when programming DMA mode bit 0x10 of register B was cleared which
resulted in overclocked PIO timing setting (iff PIO0 was used)
- when programming PIO mode bits 0x18 weren't cleared so suboptimal
timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)
* add FIXME comment about missing locking for 66MHz clock register
Also while at it:
* remove unused defines
* do a few cosmetic / CodingStyle fixes
* bump driver version
v2:
* in pdc202xx_tune_chipset() the old content of drive configuration
registers is used only by the debugging code so cover "drive_conf"
PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO

RDMA/cma: Add check to validate that cm_id is bound to a device
Several checks in the rdma_cm check against the state of the
cm_id, but only to validate that the cm_id is bound to an underlying
transport specific CM and an RDMA device. Make the check explicit
in what we're trying to check for, since we're not synchronizing
against the cm_id state.
This will allow a user to disconnect a cm_id or reject a connection
after receiving a device removal event.

The cma_iw_handler needs to validate the state of the rdma_cm_id before
processing a new connection request to ensure that a device removal is

IB/ipath: Shadow the gpio_mask register
Once upon a time, GPIO interrupts were rare. But then a chip bug in
the waldo series forced the use of a GPIO interrupt to signal packet
reception. This greatly increased the frequency of GPIO interrupts
which have the gpio_mask bits set on the waldo chips. Other bits in
the gpio_status register are used for I2C clock and data lines, these
bits are usually on. An "unlikely" annotation leftover from the old
days was improperly applied to these bits, and an unnecessary chip
mmio read was being accessed in the interrupt fast path on waldo.
Remove the stagnant unlikely annotation in the interrupt handler and
keep a shadow copy of the gpio_mask register to avoid the slow mmio
read when testing for interruptable GPIO bits.
