ioctl HDIO_OBSOLETE_IDENTITY
This patch fixes a memory overrun in function ide_get_identity_ioctl() which
chooses the size of a memory buffer depending on the ioctl command that led
to the function call, however, passes that buffer to a function which needs the
buffer size to be always chosen unconditionally.
Due to conditional compilation the memory overrun can only happen on big endian
machines. The error can be triggered using ioctl HDIO_OBSOLETE_IDENTITY. Usage
of ioctl HDIO_GET_IDENTITY is safe.

commit 2f0d0fd2a605666d38e290c5c0d2907484352dc4 ("ide-acpi: cleanup
do_drive_get_GTF()") didn't account for the lack of hwif->acpidata
check in generic_ide_suspend() [ indirect user of do_drive_get_GTF()
through ide_acpi_exec_tfs() ] resulting in broken resume when ACPI
support is enabled but ACPI data is unavailable.
Fix it by adding ide_port_acpi() helper for checking if port needs
ACPI handling and cleaning generic_ide_{suspend,resume}() to use it
instead of hiding hwif->acpidata and ide_noacpi checks in IDE ACPI
helpers (this should help in preventing similar bugs in the future).
While at it:
- kill superfluous debugging printks in ide_acpi_{get,push}_timing()

There are some devices in the wild that clear the DRQ bit during the
last word of a packet command and therefore could use a "second chance"
for that last word of data to be xferred instead of simply failing the
request. Do that by attempting to suck in those last bytes in PIO mode.
In addition, the ATA_ERR bit has to be cleared for we cannot be sure the
data is valid otherwise.
See http://bugzilla.kernel.org/show_bug.cgi?id=13399 for details.

In 86ccf37c6acd74cf7e4b7751ee045de19943c5a0 the driver was modified
to deal with the removal of the pciirq argument to ide_pci_setup_ports().
But in the conversion only the first port's IRQ gets setup.

There are some broken devices that report multiple DMA xfer modes
enabled at once (ATA spec doesn't allow it) but otherwise work fine
with DMA so just delete ide_id_dma_bug().
[ As discovered by detective work by Frans and Bart, due to how
handling of the ID block was handled before commit c419993
("ide-iops: only clear DMA words on setting DMA mode") this
check was always seeing zeros in the fields or other similar
garbage. Therefore this check wasn't actually checking anything.
Now that the tests actually check the real bits, all we see are
devices that trigger the check yet work perfectly fine, therefore
killing this useless check is the best thing to do. -DaveM ]

Currently the error gets repeated too frequently, for example each

Frans Pop reported that his CDROM drive reports a blocksize of 2352,
and this causes new warnings due to commit
e8e7b9eb11c34ee18bde8b7011af41938d1ad667 ("ide-cd: fix oops when using
growisofs").
What we're trying to do is make sure that "blocklen >> SECTOR_BITS"
is something the block layer won't choke on.
And for Frans' case "2352 >> SECTOR_BITS" is equal to
"2048 >> SECTOR_BITS", and thats "4".
So warning in this case gives no real benefit.

Add ide_host_enable_irqs() helper and use it in ide_host_register()
before registering ports. Then remove no longer needed IRQ unmasking
from in init_irq().
This should fix the problem with "screaming" shared IRQ on the first
port (after request_irq() call while we have the unexpected IRQ pending
on the second port) which was uncovered by my rework of the serialized
interfaces support.

This allows the callers to now pass down the full set of FAULT_FLAG_xyz
flags to handle_mm_fault(). All callers have been (mechanically)
converted to the new calling convention, there's almost certainly room
for architectures to clean up their code and then add FAULT_FLAG_RETRY
when that support is added.

The fault handling routines really want more fine-grained flags than a
single "was it a write fault" boolean - the callers will want to set
flags like "you can return a retry error" etc.
And that's actually how the VM works internally, but right now the
top-level fault handling functions in mm/memory.c all pass just the
'write_access' boolean around.
This switches them over to pass around the FAULT_FLAG_xyzzy 'flags'
variable instead. The 'write_access' calling convention still exists
for the exported 'handle_mm_fault()' function, but that is next.

31a985f "ipc: use __ARCH_WANT_IPC_PARSE_VERSION in ipc/util.h" would
choose the implementation of ipc_parse_version() based on a symbol
defined in <asm/unistd.h>.
But it failed to also include this header and thus broke
IPC_64-passing 32-bit userspace because the flag wasn't masked out
properly anymore and the command not understood.
Include <linux/unistd.h> to give the architecture a chance to ask for
the no-no-op ipc_parse_version().

Some hosts (hardware configurations, or particular SD/MMC slots) may
not support 4-bit bus. For example, on MPC8569E-MDS boards we can
switch between serial (1-bit only) and nibble (4-bit) modes, thought
we have to disable more peripherals to work in 4-bit mode.
Along with some small core changes, this patch modifies sdhci-of
driver, so that now it looks for "sdhci,1-bit-only" property in the
device-tree, and if specified we enable a proper quirk.

The selected 4930G model seemed to keep the subwoofer 'tuba'
function from operating correctly. Removing the existing PCI

instead of to LFE as one would expect.
This attempts to enable all functionality and keep the amount
of available mixer sliders low. Any slider that had no audible
effect on the output audio has been removed, and as such EAPD

The discussion about using "access_ok()" in get_user_pages_fast() (see
commit 7f8189068726492950bf1a2dcfd9b51314560abf: "x86: don't use
'access_ok()' as a range check in get_user_pages_fast()" for details and
end result), made us notice that x86-64 was really being very sloppy
about virtual address checking.
So be way more careful and straightforward about masking x86-64 virtual
addresses:
- All the VIRTUAL_MASK* variants now cover half of the address
space, it's not like we can use the full mask on a signed
integer, and the larger mask just invites mistakes when
applying it to either half of the 48-bit address space.
- /proc/kcore's kc_offset_to_vaddr() becomes a lot more
obvious when it transforms a file offset into a
(kernel-half) virtual address.
- Unify/simplify the 32-bit and 64-bit USER_DS definition to
be based on TASK_SIZE_MAX.
This cleanup and more careful/obvious user virtual address checking also
uncovered a buglet in the x86-64 implementation of strnlen_user(): it
would do an "access_ok()" check on the whole potential area, even if the
string itself was much shorter, and thus return an error even for valid
strings. Our sloppy checking had hidden this.
So this fixes 'strnlen_user()' to do this properly, the same way we
already handled user strings in 'strncpy_from_user()'. Namely by just
checking the first byte, and then relying on fault handling for the
rest. That always works, since we impose a guard page that cannot be
mapped at the end of the user space address space (and even if we
didn't, we'd have the address space hole).
