2014-07-18ARM: 8101/1: mach-iop13xx: fix possible build failureArnd Bergmann
After applying patch: "ARM: 8078/1: get rid of hardcoded assumptions about kernel stack size" following build failure happens on iop13xx platform: In file included from include/linux/srcu.h:33:0, from include/linux/notifier.h:15, from include/linux/reboot.h:5, from arch/arm/mach-iop13xx/include/mach/iop13xx.h:6, from arch/arm/mach-iop13xx/include/mach/hardware.h:14, from arch/arm/mach-iop13xx/include/mach/memory.h:4, from arch/arm/include/asm/memory.h:24, from arch/arm/include/asm/page.h:163, from arch/arm/include/asm/thread_info.h:17, from include/linux/thread_info.h:54, from include/asm-generic/preempt.h:4, from arch/arm/include/generated/asm/preempt.h:1, from include/linux/preempt.h:18, from include/linux/spinlock.h:50, from include/linux/seqlock.h:35, from include/linux/time.h:5, from include/uapi/linux/timex.h:56, from include/linux/timex.h:56, from include/linux/sched.h:19, from arch/arm/kernel/asm-offsets.c:13: include/linux/rcupdate.h: In function '__rcu_read_lock': >> include/linux/rcupdate.h:220:2: error: implicit declaration of function 'preempt_disable' [-Werror=implicit-function-declaration] preempt_disable(); The problem here is recursive header inclusion which could be avoided by removing linux/reboot.h from mach/iop13xxx.h. linux/reboot.h in include/mach/iop13xx.h is needed only for enum reboot_mode, so header it could be replaced with a enum declaration. Whatever patch "ARM: 8078/1: get rid of hardcoded assumptions about kernel stack size" does, I think it's good to avoid unnecessary header inclusion here in any case.

Move iop13xx PCI to fixed i/o mapping and remove io.h. This changes the PCIe bus address to start at 0x10000. Let's hope this works. If it does not, the alternative would be to revert the value we write into OIOTVR to zero and set sys->io_offset to 64K.

2011-06-21net: remove mm.h inclusion from netdevice.hAlexey Dobriyan
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-08-29async_tx: add support for asynchronous GF multiplicationDan Williams
[ Based on an original patch by Yuri Tikhonov ] This adds support for doing asynchronous GF multiplication by adding two additional functions to the async_tx API: async_gen_syndrome() does simultaneous XOR and Galois field multiplication of sources. async_syndrome_val() validates the given source buffers against known P and Q values. When a request is made to run async_pq against more than the hardware maximum number of supported sources we need to reuse the previous generated P and Q values as sources into the next operation. Care must be taken to remove Q from P' and P from Q'. For example to perform a 5 source pq op with hardware that only supports 4 sources at a time the following approach is taken: p, q = PQ(src0, src1, src2, src3, COEF({01}, {02}, {04}, {08})) p', q' = PQ(p, q, q, src4, COEF({00}, {01}, {00}, {10})) p' = p + q + q + src4 = p + src4 q' = {00}*p + {01}*q + {00}*q + {10}*src4 = q + {10}*src4 Note: 4 is the minimum acceptable maxpq otherwise we punt to synchronous-software path. The DMA_PREP_CONTINUE flag indicates to the driver to reuse p and q as sources (in the above manner) and fill the remaining slots up to maxpq with the new sources/coefficients. Note1: Some devices have native support for P+Q continuation and can skip this extra work. Devices with this capability can advertise it with dma_set_maxpq. It is up to each driver how to handle the DMA_PREP_CONTINUE flag. Note2: The api supports disabling the generation of P when generating Q, this is ignored by the synchronous path but is implemented by some dma devices to save unnecessary writes. In this case the continuation algorithm is simplified to only reuse Q as a source. Cc: H.

2009-04-08async_tx: rename zero_sum to valDan Williams
'zero_sum' does not properly describe the operation of generating parity and checking that it validates against an existing buffer. Change the name of the operation to 'val' (for 'validate'). This is in anticipation of the p+q case where it is a requirement to identify the target parity buffers separately from the source buffers, because the target parity buffers will not have corresponding pq coefficients.

2006-12-07[ARM] 3995/1: iop13xx: add iop13xx supportDan Williams
The iop348 processor integrates an Xscale (XSC3 512KB L2 Cache) core with a Serial Attached SCSI (SAS) controller, multi-ported DDR2 memory controller, 3 Application Direct Memory Access (DMA) controllers, a 133Mhz PCI-X interface, a x8 PCI-Express interface, and other peripherals to form a system-on-a-chip RAID subsystem engine. The iop342 processor replaces the SAS controller with a second Xscale core for dual core embedded applications. The iop341 processor is the single core version of iop342. This patch supports the two Intel customer reference platforms iq81340mc for external storage and iq81340sc for direct attach (HBA) development.
