2010-08-12CRIS: Define io_remap_pfn_range as remap_pfn_rangeJesper Nilsson1-0/+3
CRIS don't need any special mapping for io, but didn't define this, meaning that all uses of io_remap_pfn_range lead to compile errors. This fixes a compile error introduced in CRIS when drivers/mtd/mtdchar.c mmap handling was changed in commit dd02b67d5e9e7896891fa27eb5db65f55a290998 Signed-off-by: Jesper Nilsson <[email protected]>

2010-08-12mfd: Add TPS6586x driverMike Rapoport4-0/+437
Add mfd core driver for TPS6586x PMICs family. The driver provides I/O access for the sub-device drivers and performs regstration of the sub-devices based on the platform requirements. In addition it implements GPIOlib interface for the chip GPIOs.

2010-08-12mfd: AB8500 mask off irrelevant bits from the SPI messageLinus Walleij1-1/+6

2010-08-12mfd: Fix 88pm860x uninitialized variable and clean upDan Carpenter1-40/+32
The original code had a compile warning: drivers/mfd/88pm860x-core.c:431: warning: ‘ret’ may be used uninitialized in this function It seems like the warning is valid if either pdata or pdata->touch is NULL. This patch checks pdata and pdata->touch at the beginning of the function. That means everything can be pulled in one indent level. Now all the statements fit within the 80 character limit. Also at that point the "use_gpadc" variable isn't needed and removing it simplifies the logic.

2010-08-12dm mpath: support discardMike Snitzer1-0/+10
Enable discard support in the DM multipath target. This discard support depends on a few discard-specific fixes to the block layer's request stacking driver methods. Discard requests are optional so don't allow a failed discard to trigger path failures. If there is a real problem with a given path the barriers associated with the discard (either before or after the discard) will cause path failure. That said, unconditionally passing discard failures up the stack is not ideal. This must be fixed once DM has more information about the nature of the underlying storage failure.

2010-08-12dm stripe: support discardsMikulas Patocka1-0/+39
The DM core will submit a discard bio to the stripe target for each stripe in a striped DM device. The stripe target will determine stripe-specific portions of the supplied bio to be remapped into individual (at most 'num_discard_requests' extents). If a given stripe-specific discard bio doesn't touch a particular stripe the bio will be dropped.

2010-08-12dm: split discard requests on target boundariesMike Snitzer1-24/+23
Update __clone_and_map_discard to loop across all targets in a DM device's table when it processes a discard bio. If a discard crosses a target boundary it must be split accordingly. Update __issue_target_requests and __issue_target_request to allow a cloned discard bio to have a custom start sector and size.
