2010-05-17ARM: mx3: Fix a race condition in mxcmmcDaniel Mack
From cefcdab08d1c9636c4a7290bc2bbe937d051bce4 Mon Sep 17 00:00:00 2001 From: Volker Ernst <volker.ernst@txtr.com> Date: Mon, 26 Apr 2010 22:51:07 +0200 Subject: [PATCH] ARM: mx3: Fix a race condition in mxcmmc This fixes a race condition regarding interrupt bits in the SDHC controller driver code. In case of PIO-transfer it does not clear SDHC-status bit#11/12 in the INT-handler anymore. INT-handler might be called during an ongoing PIO-data-transfer (with some other INT-flag set) and PIO-transfer depends on these bits being set to detect the end of the data-transfer. This also means that at the end of PIO- transfer that PIO-software has to clear these bits itself. However in case of DMA-transfer these bits have to be cleared in the INT-handler, because they are used to generate INTs then. Works solid, no more problems here, can transfer big files.

2010-04-14ARM: MXC: mxcmmc: work around a bug in the SDHC busy line handlingDaniel Mack
MX3 SoCs have a silicon bug which corrupts CRC calculation of multi-block transfers when connected SDIO peripheral doesn't drive the BUSY line as required by the specs. One way to prevent this is to only allow 1-bit transfers. Another way is playing tricks with the DMA engine, but this isn't mainline yet. So for now, we live with the performance drawback of 1-bit transfers until a nicer solution is found. This patch introduces a new host controller callback 'init_card' which is for now only called from mmc_sdio_init_card().

2010-04-14MXC: mxc_nand: support i.MX21Ivo Clarysse
On i.MX21 SoCs, if the NFC_CONFIG1:NFC_INT_MASK bit is set, NFC_CONFIG2:NFC_INT always reads out zero, even if an operation is completed. This patch uses enable_irq and disable_irq_nosync instead of NFC_CONFIG1:NFC_INT_MASK to mask NFC interrupts. This allows NFC_CONFIG2:NFC_INT to also be used to detect operation completion on i.MX21. The i.MX21 NFC does not signal reset completion using NFC_CONFIG1:NFC_INT_MASK, so instead reset completion is tested by checking if NFC_CONFIG2 becomes 0.

2010-04-12sparc64: Fix memory leak in pci_register_iommu_region().David S. Miller
Found by kmemleak. If request_resource() fails, we leak the struct resource we allocated to represent the IOMMU mapping area. This actually happens on sun4v machines because the IOMEM area is only reported sans the IOMMU region, unlike all previous systems. I'll need to fix that at some point, but for now fix the leak.

2010-04-12sparc64: Add kmemleak annotation to sun4v_build_virq()David S. Miller
The only reference we store to this memory is in the form of a physical address, so kmemleak can't see it. Add a kmemleak_not_leak() annotation. It's probably useful to be able to look at a dump of these things either via debugfs or similar, and thus we could at some point store them in some kind of table and therefore get rid of this annotation.
