2010-04-14ARM: MXC: mxcmmc: work around a bug in the SDHC busy line handlingDaniel Mack3-0/+25
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 Clarysse1-16/+25
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. Miller1-3/+8
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. Signed-off-by: David S. Miller <[email protected]>
2010-04-12sparc64: Add kmemleak annotation to sun4v_build_virq()David S. Miller1-0/+8
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.

It's the only way we'll be able to implement the function graph tracer properly. A positive is that we no longer have to worry about the linker over-optimizing the tail call, since we don't use a tail call any more. Signed-off-by: David S. Miller <[email protected]>

2010-04-12sparc64: Adjust __raw_local_irq_save() to cooperate in NMIs.David S. Miller1-2/+12
If we are in an NMI then doing a plain raw_local_irq_disable() will write PIL_NORMAL_MAX into %pil, which is lower than PIL_NMI, and thus we'll re-enable NMIs and recurse. Doing a simple: %pil = %pil | PIL_NORMAL_MAX does what we want, if we're already at PIL_NMI (15) we leave it at that setting, else we set it to PIL_NORMAL_MAX (14). This should get the function tracer working on sparc64. Signed-off-by: David S. Miller <[email protected]>
2010-04-12sparc64: Use kstack_valid() in die_if_kernel().David S. Miller1-23/+3
