task_end_request() modified to always call ide_end_drive_cmd()
for taskfile requests. Previously, ide_end_drive_cmd() was
called only when IDE_TFLAG_FLAGGED was set. Also,
ide_dma_intr() is modified to use task_end_request().
Enables TASKFILE ioctls to get valid register outputs on
successful completion.

In ide_taskfile_ioctl(), there was a race condition involving
drive->io_32bit. It was cleared and restored during ioctl
requests but there was no synchronization with other requests.
So, other requests could execute with the altered ->io_32bit
setting or updated drive->io_32bit could be overwritten by
ide_taskfile_ioctl().
This patch adds IDE_TFLAG_IO_16BIT flag to indicate to
ide_pio_datablock() that 16-bit I/O is needed regardless of
drive->io_32bit settting.

Remove broken disk byte-swapping support:
- it can cause a data corruption on SMP (or if using PREEMPT on UP)
- all data coming from disk are byte-swapped by taskfile_*_data() which
results in incorrect identify data being reported by /proc/ide/ and IOCTLs
- "hdx=bswap/byteswap" kernel parameter has been broken on m68k host drivers
(including Atari/Q40 ones) since 2.5.x days (because of 'hwif' zero-ing)
- byte-swapping is limited to PIO transfers (for working with TiVo disks on
x86 machines using user-space solutions or dm-byteswap should result in
much better performance because DMA can be used)

* Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c
file for probing PCI host drivers registered with IDE core (special case
for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of
the ordering in which all IDE host drivers are probed when IDE is built-in
during link time.
* Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch
specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris
arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific).
* Move probing of ide-cris (cris arch specific) host driver before cmd640
(x86 arch specific).
* Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends
on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300
(h8300 arch specific).
* Add "probe_vlb" kernel parameter to cmd640 host driver and update
Documentation/ide.txt accordingly.
* Make IDE_ARM config option visible so it can also be disabled if needed.
* Remove bogus comment from ide.c while at it.
v2:
* Fix two issues spotted by Sergei:
- replace ENOMEM error value by ENOENT in ide-h8300 host driver
- fix MODULE_PARM_DESC() in cmd640 host driver

There's no need to have a sized array in the prototype, might as well

In s390's spin_lock_irqsave, interrupts remain disabled while
spinning. In other architectures like x86 and powerpc, interrupts are
re-enabled while spinning if IRQ is not masked before spin_lock_irqsave
is called.
The following patch re-enables interrupts through local_irq_restore
while spinning for a lock acquisition.
This can improve system response.

This patch fixes a problem with the following scenario:
1. Linux booted from DASD "A"
2. Reboot from DASD "B" using "/sys/firmware/reipl/ccw/device"
3. Reboot DASD "B"
Without this patch in step 3 on newer s390 systems under LPAR instead of
DASD "B", DASD "A" will be booted. The reason is that in step 2 we use CCW
reipl and in step 3 we use DIAG308 (subcode 3) reipl. DIAG308 does not
notice the CCW reipl and still thinks that it has to reboot DASD "A".
Before applying this fix, ensure to have MCF RJ9967101E or z9 GA3 base driver
installed.

In case of a kernel panic it is currently possible to specify that a dump
should be created, the system should be rebooted or stopped. Virtual sysfs
files under the directory /sys/firmware/ are used for that configuration.
In addition to that, there are kernel parameters 'vmhalt', 'vmpoff'
and 'vmpanic', which can be used to specify z/VM commands, which are
automatically executed in case of halt, power off or a kernel panic.
This patch combines both functionalities and allows to specify the z/VM CP
commands also via sysfs attributes. In addition to that, it enhances the
existing handling of shutdown triggers (e.g. halt or panic) and associated
shutdown actions (e.g. dump or reipl) and makes it more flexible.

Currently the vmalloc area starts at a dynamic address depending on
the memory size. There was also an 8MB security hole after the
physical memory to catch out-of-bounds accesses.
We can simplify the code by putting the vmalloc area explicitely at
the top of the kernel mapping and setting the vmalloc size to a fixed
value of 128MB/128GB for 31bit/64bit systems. Part of the vmalloc
area will be used for the vmem_map. This leaves an area of 96MB/1GB
for normal vmalloc allocations.

The clear-by-asce operation of the idte instruction gets an asce
(address-space-control-element) as argument to specify which TLBs
need to get flushed. The current code passes a plain pointer to
the start of the pgd without the additional bits which would make
the pointer an asce. The current machines don't mind the difference
but a future model might want to use the designation type control
bits in the asce as a filter for the TLBs to flush.

Add a new interface so that cpus can be put into standby state and
configured state.
Only offline cpus can be put into standby state or configured state.
For that the new percpu sysfs attribute "configure" must be used.
To put a cpu in standby state a "0" must be written to the attribute.
In order to switch it into configured state a "1" must be written to
the attribute.
Only cpus in configured state can be brought online.
In addition this patch introduces a static mapping of physical to
logical cpus. As a result only the sysfs directories of present cpus
will be created. To scan for new cpus the new sysfs attribute "rescan"
must be used.
Writing to /sys/devices/system/cpu/rescan will trigger a rescan of
cpus and will create directories for new cpus.
On IPL only configured cpus will be used. And on reboot/shutdown all
cpus will remain in their current state (configured/standby).

An IPoIB subnet on an IB fabric that spans multiple IB subnets can't
use link-local scope in multicast GIDs. The existing routines that
map IP/IPv6 multicast addresses into IB link-level addresses hard-code
the scope to link-local, and they also leave the partition key field
uninitialised. This patch adds a parameter (the link-level broadcast
address) to the mapping routines, allowing them to initialise both the
scope and the P_Key appropriately, and fixes up the call sites.
The next step will be to add a way to configure the scope for an IPoIB
interface.

This is based on user feedback from Doug Ledford at RedHat:
Events that occur on an rdma_cm_id are reported to userspace through an
event channel. Connection request events are reported on the event
channel associated with the listen. When the connection is accepted, a
new rdma_cm_id is created and automatically uses the listen event
channel. This is suboptimal where the user only wants listen events on
that channel.
Additionally, it may be desirable to have events related to connection
establishment use a different event channel than those related to
already established connections.
Allow the user to migrate an rdma_cm_id between event channels. All
pending events associated with the rdma_cm_id are moved to the new event
channel.

* Add IDE_HFLAG_ABUSE_SET_DMA_MODE host flag and use it to decide
what to do with transfer modes < XFER_PIO_0 in ide_set_xfer_rate().
* Set IDE_HFLAG_ABUSE_SET_DMA_MODE in host drivers that need it
(aec62xx, amd74xx, cs5520, cs5535, hpt34x, hpt366, pdc202xx_old,
serverworks, tc86c001 and via82cxxx) and cleanup ->set_dma_mode
methods in host drivers that don't (IDE core code guarantees that
->set_dma_mode will be called only for modes which are present
in SWDMA/MWDMA/UDMA masks).
While at it:
* Add IDE_HFLAGS_HPT34X/HPT3XX/PDC202XX/SVWKS define in
hpt34x/hpt366/pdc202xx_old/serverworks host driver.
There should be no functionality changes caused by this patch.

The maximum value used currently for 'extra' field in struct ide_port_info
is 240.
Make 'extra' u8 so it packs nicely together with enablebits[] and 'chipset'
fields (ide_pci_enablebit_t is 3 bytes and hwif_chipset_t is 1 byte).

* Export ide_get_lba_addr().
* Convert idedisk_{read_native,set}_max_address() to use ide_get_lba_addr().
* Remove incorrect comment from idedisk_read_native_max_address()
(noticed by Sergei).

* Factor out code reading taskfile registers from ide_end_drive_cmd()
to the new ide_tf_read() helper.
* Add IDE_TFLAG_IN_* taskfile flags to indicate the need to load
particular IDE taskfile register in ide_tf_read().
* Update ide_end_drive_cmd() to set respective IDE_TFLAG_IN_* taksfile flags.
* Add ide_get_lba_addr() for getting LBA sector address from taskfile struct.
* Factor out code getting sector address from ide_dump_ata_status()
to the new ide_dump_sector() function.
* Convert ide_dump_sector() to use ide_tf_read() and ide_get_lba_addr().
* Remove no longer needed ide_read_24().
The only change in functionality caused by this patch is that
ide_dump_ata_status() no longer prints "high"/"low" parts of LBA48
sector address (of course LBA48 sector address is still printed).

* Add IDE_TFLAG_DMA_PIO_FALLBACK taskfile flag to indicate the need
to skip loading taskfile registers in do_rw_taskfile().
* Export do_rw_taskfile().
* Convert __ide_do_rw_disk() to use do_rw_taskfile().
* Unexport ide_tf_load().
* Unexport {pre_task_out,task_in}_intr() and make it static.
* Remove incorrect comment about do_rw_taskfile() from <linux/ide.h>.
There should be no functionality changes caused by this patch.
v2:
* Add missing blk_fs_request() check to task_dma_ok() (for VDMA).

* Add IDE_TFLAG_CUSTOM_HANDLER taskfile flag and use it for internal requests
which require custom handlers. Check the flag in do_rw_taskfile() and set
handler accordingly.
* Cleanup ide_init_{specify,restore,setmult}_cmd() and rename it to
ide_tf_set_{specify,restore,setmult}_cmd().
* Make {set_geometry,recal,set_multmode}_intr() static.
* Remove no longer needed 'handler' field from ide_task_t.
v2:
* 'handler' in do_rw_taskfile() must be set to NULL initially.
There should be no functionality changes caused by this patch.
