After commit 26b88520 ("mmc: omap_hsmmc: remove private DMA API implementation"), the Nokia N800 here stopped booting: [ 2.086181] Waiting for root device /dev/mmcblk0p1... [ 2.324066] Unhandled fault: imprecise external abort (0x406) at 0x00000000 [ 2.331451] Internal error: : 406 [#1] ARM [ 2.335784] Modules linked in: [ 2.339050] CPU: 0 Not tainted (3.6.0-rc3 #60) [ 2.344146] PC is at default_idle+0x28/0x30 [ 2.348602] LR is at trace_hardirqs_on_caller+0x15c/0x1b0 ... This turned out to be due to memory corruption caused by long-broken PIO code in drivers/mmc/host/omap.c. (Previously, this driver had been using DMA; but the above commit caused the MMC driver to fall back to PIO mode with an unmodified Kconfig.) The PIO code, added with the rest of the driver in commit 730c9b7e ("[MMC] Add OMAP MMC host driver"), confused bytes with 16-bit words. This bug caused memory located after the PIO transfer buffer to be corrupted with transfers larger than 32 bytes. The driver also did not increment the buffer pointer after the transfer occurred. This bug resulted in data corruption during any transfer larger than 64 bytes. Signed-off-by:

For several MoviNAND eMMC parts, there are known issues with secure erase and secure trim. For these specific MoviNAND devices, we skip these operations. Specifically, there is a bug in the eMMC firmware that causes unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE enabled.

The documentation for the dw_mmc part says that the low power mode should normally only be set for MMC and SD memory and should be turned off for SDIO cards that need interrupts detected. The best place I could find to do this is when the SDIO interrupt was first enabled. I rely on the fact that dw_mci_setup_bus() will be called when it's time to reenable. Signed-off-by:

Data transfer will be continued until all the bytes are transmitted, even if data crc error occurs during a multiple-block data transfer. This means RXDR/TXDR interrupts will occurs until data transfer is terminated. Early setting of host->sg to NULL prevents going into xxx_data_pio functions, hence permanent unhandled RXDR/TXDR interrupts occurs. And checking error interrupt status in the xxx_data_pio functions is no need because dw_mci_interrupt does do the same. This patch also removes it. Signed-off-by:

Datasheet of SYNOPSYS mentions that DTO(Data Transfer Over) interrupt will be raised even if some error interrupts, however it is actually found that DTO does not occur. SYNOPSYS has confirmed this issue. Current implementation defers the call of tasklet_schedule until DTO when the error interrupts is happened. This patch fixes error handling. Signed-off-by:

RINTSTS status includes masked interrupts as well as unmasked. data_status and cmd_status are set by value of RINTSTS in interrupt handler and tasklet finally uses it to decide whether error is happened or not. In addition, MINTSTS status is used for setting data_status in PIO. Masked error interrupt will not be handled and that status can be considered non-error case. Signed-off-by:

Even if the datasheet says that the not busy flag has to be used only for write operations, it's false except for version lesser than v2xx. Not waiting on the not busy flag for read operations can cause the controller to hang-up during the initialization of some SD cards with DMA after the first CMD6 -- the next command is sent too early.

Since commit 30832ab5 ("mmc: sdhci: Always pass clock request value zero to set_clock host op") was merged, esdhc_set_clock starts hitting "if (clock == 0)" where ESDHC_SYSTEM_CONTROL has been operated. This causes SDHCI card-detection function being broken. Fix the regression by moving "if (clock == 0)" above ESDHC_SYSTEM_CONTROL operation. Signed-off-by:

Pull arm-soc cpuidle enablement for OMAP from Olof Johansson: "Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but didn't go in because the pull request ended up rejected. So it just got merged, and we got this staged branch that enables the coupled cpuidle code on OMAP. With a stable git workflow from the other maintainer we could have staged this earlier, but that wasn't the case so we have had to merge it late. The alternative is to hold it off until 3.7 but given that the code is well-isolated to OMAP and they are eager to see it go in, I didn't push back hard in that direction." * tag 'pm2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: OMAP4: CPUidle: Open broadcast clock-event device.

Merge tag 'ecryptfs-3.6-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs Pull ecryptfs fixes from Tyler Hicks: - Fixes a bug when the lower filesystem mount options include 'acl', but the eCryptfs mount options do not - Cleanups in the messaging code - Better handling of empty files in the lower filesystem to improve usability. Failed file creations are now cleaned up and empty lower files are converted into eCryptfs during open(). - The write-through cache changes are being reverted due to bugs that are not easy to fix. Stability outweighs the performance enhancements here. - Improvement to the mount code to catch unsupported ciphers specified in the mount options * tag 'ecryptfs-3.6-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: eCryptfs: check for eCryptfs cipher support at mount eCryptfs: Revert to a writethrough cache model eCryptfs: Initialize empty lower files when opening them eCryptfs: Unlink lower inode when ecryptfs_create() fails eCryptfs: Make all miscdev functions use daemon ptr in file private_data eCryptfs: Remove unused messaging declarations and function eCryptfs: Copy up POSIX ACL and read-only flags from lower mount

Borislav Petkov reports that the new warning added in commit 88fdf75d ("mm: warn if pg_data_t isn't initialized with zero") triggers for him, and it is the node_start_pfn field that has already been initialized once. The call trace looks like this: x86_64_start_kernel -> x86_64_start_reservations -> start_kernel -> setup_arch -> paging_init -> zone_sizes_init -> free_area_init_nodes -> free_area_init_node and (with the warning replaced by debug output), Borislav sees On node 0 totalpages: 4193848 DMA zone: 64 pages used for memmap DMA zone: 6 pages reserved DMA zone: 3890 pages, LIFO batch:0 DMA32 zone: 16320 pages used for memmap DMA32 zone: 798464 pages, LIFO batch:31 Normal zone: 52736 pages used for memmap Normal zone: 3322368 pages, LIFO batch:31 free_area_init_node: pgdat->node_start_pfn: 4423680 <---- On node 1 totalpages: 4194304 Normal zone: 65536 pages used for memmap Normal zone: 4128768 pages, LIFO batch:31 free_area_init_node: pgdat->node_start_pfn: 8617984 <---- On node 2 totalpages: 4194304 Normal zone: 65536 pages used for memmap Normal zone: 4128768 pages, LIFO batch:31 free_area_init_node: pgdat->node_start_pfn: 12812288 <---- On node 3 totalpages: 4194304 Normal zone: 65536 pages used for memmap Normal zone: 4128768 pages, LIFO batch:31 so remove the bogus warning for now to avoid annoying people.

The only way to write LATCHED registers to write LATCH_BIT to LATCH register, that will latch COUNTER into LATCHED.e.g. writel_relaxed(SIRFSOC_TIMER_LATCH_BIT, sirfsoc_timer_base + SIRFSOC_TIMER_LATCH); Writing values to LATCHED registers directly is useless at all. Signed-off-by:

The initial ->atomic_open op was carried over from the old intent code, which was incomplete and didn't really work. Replace it with a fresh method. In particular: * always attempt to do an atomic open+lookup, both for the create case and for lookups of existing files. * fix symlink handling by returning 1 to the VFS so that we can follow the link to its destination. This fixes a longstanding ceph bug (#2392). Signed-off-by: -

Pull ARM DMA engine updates from Russell King: "This looks scary at first glance, but what it is is: - a rework of the sa11x0 DMA engine driver merged during the previous cycle, to extract a common set of helper functions for DMA engine implementations. - conversion of amba-pl08x.c to use these helper functions. - addition of OMAP DMA engine driver (using these helper functions), and conversion of some of the OMAP DMA users to use DMA engine. Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."
