Clean up pda_power interrupt handling: Prior to this patch, the driver would pass information it needed to the interrupt handler dev_id pointer, and then prompt forget it ever did so, recreating that same information after a couple passes through the timer-based state machine. This patch removes the redundant checks by passing the pda_power_supply[] pointer through the state machine. The current code passed 'irq' through the state machine, as an index to recreate the pointer, when we could more simply pass around the pointer itself. This patch makes it easier to remove the 'irq' argument in the future, in addition to cleaning up the driver today. Signed-off-by: NJeff Garzik <jeff@garzik.org>

This reverts commit 9faf65fb. It bit people like Michal Piotrowski: "My system is too secure, I can not login :)" because it changed how CONFIG_NETLABEL worked, and broke older SElinux policies. As a result, quoth James Morris: "Can you please revert this patch? We thought it only affected people running MLS, but it will affect others. Sorry for the hassle."

The Intel(R) IOP series of i/o processors integrate an Xscale core with raid acceleration engines. The capabilities per platform are: iop219: (2) copy engines iop321: (2) copy engines (1) xor and block fill engine iop33x: (2) copy and crc32c engines (1) xor, xor zero sum, pq, pq zero sum, and block fill engine iop34x (iop13xx): (2) copy, crc32c, xor, xor zero sum, and block fill engines (1) copy, crc32c, xor, xor zero sum, pq, pq zero sum, and block fill engine The driver supports the features of the async_tx api: * asynchronous notification of operation completion * implicit (interupt triggered) handling of inter-channel transaction dependencies The driver adapts to the platform it is running by two methods. 1/ #include <asm/arch/adma.h> which defines the hardware specific iop_chan_* and iop_desc_* routines as a series of static inline functions 2/ The private platform data attached to the platform_device defines the capabilities of the channels 20070626: Callbacks are run in a tasklet. Given the recent discussion on LKML about killing tasklets in favor of workqueues I did a quick conversion of the driver. Raid5 resync performance dropped from 50MB/s to 30MB/s, so the tasklet implementation remains until a generic softirq interface is available. Changelog: * fixed a slot allocation bug in do_iop13xx_adma_xor that caused too few slots to be requested eventually leading to data corruption * enabled the slot allocation routine to attempt to free slots before returning -ENOMEM * switched the cleanup routine to solely use the software chain and the status register to determine if a descriptor is complete. This is necessary to support other IOP engines that do not have status writeback capability * make the driver iop generic * modified the allocation routines to understand allocating a group of slots for a single operation * added a null xor initialization operation for the xor only channel on iop3xx * support xor operations on buffers larger than the hardware maximum * split the do_* routines into separate prep, src/dest set, submit stages * added async_tx support (dependent operations initiation at cleanup time) * simplified group handling * added interrupt support (callbacks via tasklets) * brought the pending depth inline with ioat (i.e. 4 descriptors) * drop dma mapping methods, suggested by Chris Leech * don't use inline in C files, Adrian Bunk * remove static tasklet declarations * make iop_adma_alloc_slots easier to read and remove chances for a corrupted descriptor chain * fix locking bug in iop_adma_alloc_chan_resources, Benjamin Herrenschmidt * convert capabilities over to dma_cap_mask_t * fixup sparse warnings * add descriptor flush before iop_chan_enable * checkpatch.pl fixes * gpl v2 only correction * move set_src, set_dest, submit to async_tx methods * move group_list and phys to async_tx Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: NDan Williams <dan.j.williams@intel.com>

When a stripe is being expanded bulk copying takes place to move the data from the old stripe to the new. Since raid5_run_ops only operates on one stripe at a time these bulk copies are handled in-line under the stripe lock. In the dma offload case we poll for the completion of the operation. After the data has been copied into the new stripe the parity needs to be recalculated across the new disks. We reuse the existing postxor functionality to carry out this calculation. By setting STRIPE_OP_POSTXOR without setting STRIPE_OP_BIODRAIN the completion path in handle stripe can differentiate expand operations from normal write operations.

When a read bio is attached to the stripe and the corresponding block is marked R5_UPTODATE, then a read (biofill) operation is scheduled to copy the data from the stripe cache to the bio buffer. handle_stripe flags the blocks to be operated on with the R5_Wantfill flag. If new read requests arrive while raid5_run_ops is running they will not be handled until handle_stripe is scheduled to run again.

Check operations are scheduled when the array is being resynced or an explicit 'check/repair' command was sent to the array. Previously check operations would destroy the parity block in the cache such that even if parity turned out to be correct the parity block would be marked !R5_UPTODATE at the completion of the check. When the operation can be carried out by a dma engine the assumption is that it can check parity as a read-only operation. If raid5_run_ops notices that the check was handled by hardware it will preserve the R5_UPTODATE status of the parity disk. When a check operation determines that the parity needs to be repaired we reuse the existing compute block infrastructure to carry out the operation. Repair operations imply an immediate write back of the data, so to differentiate a repair from a normal compute operation the STRIPE_OP_MOD_REPAIR_PD flag is added.
