2013-10-29device: Make dev_WARN/dev_WARN_ONCE print device as well as driver nameBjorn Helgaas
dev_WARN() and dev_WARN_ONCE() are annoying because (1) they include only the driver name, not the device name, and (2) they print a spurious newline in the middle. This results in messages like this that are less useful than they should be: [ 40.094995] Device pcieport disabling already-disabled device This patch makes them work more like dev_printk().

2013-10-29sysfs: separate out dup filename warning into a separate functionTejun Heo
Separate out sysfs_warn_dup() out of sysfs_add_one(). This will help separating out the core sysfs functionalities into kernfs so that it can be used by non-sysfs users too.

2013-10-29sysfs: honor bin_attr.attr.ignore_lockdepTejun Heo
ignore_lockdep is currently honored only for regular files. There's no reason to ignore it for bin files. Update sysfs_ignore_lockdep() so that bin_attr.attr.ignore_lockdep works too. While this doesn't have any in-kernel user, this unifies the behaviors between regular and bin files and will help later changes.

2013-10-29sysfs: merge sysfs_elem_bin_attr into sysfs_elem_attrTejun Heo
3124eb1679 ("sysfs: merge regular and bin file handling") folded bin file handling into regular file handling. Among other things, bin file now shares the same open path including sysfs_open_dirent association using sysfs_dirent->s_attr.open. This is buggy because ->s_bin_attr lives in the same union and doesn't have the field. This bug doesn't trigger because sysfs_elem_bin_attr doesn't have an active field at the conflicting position. It does have a field "buffers" but it isn't used anymore. This patch collapses sysfs_elem_bin_attr into sysfs_elem_attr so that the bin_attr is accessed through ->s_attr.bin_attr which lives with ->s_attr.attr in an anonymous union. The code paths already assume bin_attr contains attr as the first element, so this doesn't add any more assumptions while making it explicit that the two types are handled together.

2013-10-29MIPS: mm: Use scratch for PGD when !CONFIG_MIPS_PGD_C0_CONTEXTJayachandran C
Allow usage of scratch register for current pgd even when MIPS_PGD_C0_CONTEXT is not configured. MIPS_PGD_C0_CONTEXT is set for 64r2 platforms to indicate availability of Xcontext for saving cpuid, thus freeing Context to be used for saving PGD. This option was also tied to using a scratch register for storing PGD. This commit will allow usage of scratch register to store the current pgd if one can be allocated for the platform, even when MIPS_PGD_C0_CONTEXT is not set. The cpuid will be kept in the CP0 Context register in this case. The code to store the current pgd for the TLB miss handler is now generated in all cases. When scratch register is available, the PGD is also stored in the scratch register.

2013-10-29MIPS: Tell R4k SC and MC variations apartMaciej W. Rozycki
There is no reliable way to tell R4000/R4400 SC and MC variations apart, however simple heuristic should give good results. Only the MC version supports coherent caching so we can rely on such a mode having been set for KSEG0 by the power-on firmware to reliably indicate an MC processor. SC processors reportedly hang on coherent cached memory accesses and Linux is linked to a cached load address so the firmware has to use the correct caching mode to download the kernel image in a cached mode successfully. OTOH if the firmware chooses to use either the non-coherent cached or the uncached mode for KSEG0 on an MC processor, then the SC variant will be reported, just as we currently do, so no regression here.

2013-10-29MIPS: DECstation I/O ASIC DMA interrupt classesMaciej W. Rozycki
This change complements commits d0da7c002f7b2a93582187a9e3f73891a01d8ee4 [MIPS: DEC: Convert to new irq_chip functions] and 5359b938c088423a28c41499f183cd10824c1816 [MIPS: DECstation I/O ASIC DMA interrupt handling fix] and implements automatic handling of the two classes of DMA interrupts the I/O ASIC implements, informational and errors. Informational DMA interrupts do not stop the transfer and use the `handle_edge_irq' handler that clears the request right away so that another request may be recorded while the previous is being handled. DMA error interrupts stop the transfer and require a corrective action before DMA can be reenabled. Therefore they use the `handle_fasteoi_irq' handler that only clears the request on the way out. Because MIPS processor interrupt inputs, one of which the I/O ASIC's interrupt controller is cascaded to, are level-triggered it is recommended that error DMA interrupt action handlers are registered with the IRQF_ONESHOT flag set so that they are run with the interrupt line masked. This change removes the export of clear_ioasic_dma_irq that now does not have to be called by device drivers to clear interrupts explicitly anymore. Originally these interrupts were cleared in the .end handler of the `irq_chip' structure, before it was removed. Signed-off-by: Maciej W.
