2013-09-17usb: gadget: mv_u3d_core: fix violation of locking discipline in ↵Alexey Khoroshilov
mv_u3d_ep_disable() mv_u3d_nuke() expects to be calles with ep->u3d->lock held, because mv_u3d_done() does. But mv_u3d_ep_disable() calls it without lock that can lead to unpleasant consequences.

mips allmodconfig fails with ERROR: "copy_from_user_page" [drivers/staging/lustre/lustre/libcfs/libcfs.ko] undefined! which is due to LUSTRE using copy_from_user_page which is not exported by any architecture.

Enable only those interrupts that we can handle & acknowledge in the interrupt handler. At least on EdgeRouter Lite, the hardware may occasionally interrupt with some error condition when the physical link status changes frequently. Since the interrupt condition is not acked properly, this leads to the following warning and the IRQ gets disabled completely: [ 41.324700] eth0: Link down [ 44.324721] eth0: 1000 Mbps Full duplex, port 0, queue 0 [ 44.885590] irq 117: nobody cared (try booting with the "irqpoll" option) [ 44.892397] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.11.0-rc5-edge-los.git-27d042f-dirty-00950-gaa42f2d-dirty #8 [ 44.902825] Stack : ffffffff815c0000 0000000000000004 0000000000000003 0000000000000000 ffffffff81fd0000 ffffffff815c0000 0000000000000004 ffffffff8118530c ffffffff815c0000 ffffffff811858d8 0000000000000000 0000000000000000 ffffffff81fd0000 ffffffff81fc0000 ffffffff8152f3a0 ffffffff815b7bf7 ffffffff81fc6688 ffffffff815b8060 0000000000000000 0000000000000000 0000000000000000 ffffffff815346c8 ffffffff815346b0 ffffffff814a6a18 ffffffff8158b848 ffffffff81145614 ffffffff81593800 ffffffff81187174 ffffffff815b7d00 ffffffff8158b760 0000000000000000 ffffffff814a9184 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 ffffffff811203b8 0000000000000000 0000000000000000 ...

2013-09-17dma/Kconfig: Make TI_EDMA select TI_PRIV_EDMAJosh Boyer
The TI_EDMA driver unconditionally calls functions provided by the TI_PRIV_EDMA code, but it doesn't force that to be built-in. If that isn't otherwise enabled somewhere, you can get build errors like: linux-3.12.0-0.rc0.git1.1.fc21.armv7hl/drivers/dma/edma.c:593: undefined reference to `edma_free_slot' drivers/built-in.o: In function `edma_terminate_all': linux-3.12.0-0.rc0.git1.1.fc21.armv7hl/drivers/dma/edma.c:169: undefined reference to `edma_stop' drivers/built-in.o: In function `edma_execute': linux-3.12.0-0.rc0.git1.1.fc21.armv7hl/drivers/dma/edma.c:122: undefined reference to `edma_write_slot' linux-3.12.0-0.rc0.git1.1.fc21.armv7hl/drivers/dma/edma.c:149: undefined reference to `edma_link' linux-3.12.0-0.rc0.git1.1.fc21.armv7hl/drivers/dma/edma.c:152: undefined reference to `edma_start' Make TI_EDMA select TI_PRIV_EDMA to avoid this.

The L2 cache controller(PL310) version on the i.MX6D/Q is r3p1-50rel0 The L2 cache controller(PL310) version on the i.MX6DL/SOLO/SL is r3p2 But according to ARM PL310 errata: 752271 ID: 752271: Double linefill feature can cause data corruption Fault Status: Present in: r3p0, r3p1, r3p1-50rel0. Fixed in r3p2 Workaround: The only workaround to this erratum is to disable the double linefill feature. This is the default behavior. without this patch, you will meet the following error when run the memtester application at: http://pyropus.ca/software/memtester/ FAILURE: 0x00100000 != 0x00200000 at offset 0x01365664.

2013-09-17ARM: imx51.dtsi: fix PATA device clockArnaud Patard (Rtp)
Commit 718a350 (ARM: i.MX51: Add PATA support) adds pata support to the imx51.dtsi file and is using clock 161. The problem is that the right clock is 172, according to commit 5d530bb (ARM: i.MX5: Add PATA and SRTC clocks). Using the clock 172 makes things work again (and kills a nasty system freeze).
