* Kobject: the cris iop_fw_load.c code is brokenGreg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | | | This code is really really really broken. So much so that it's almost impossible to fix with a simple patch, so just comment out the offending registration with the kobject core, and mark the driver as broken. The problem is that the code is trying to register a "raw" struct device, which is not allowed. struct device is only for use within the driver model. This is being done to try to use the firmware layer which wants a struct device. To properly fix this, use something easy, like a platform device, which is a struct device and can be used for this kind of thing.

* CRISv32: add cache flush operationsJesper Nilsson2007-11-14
| | | | | | | | | | | | | | | These are needed due to a cache bug, and can be used to make sure that the DMA descriptors are flushed to memory and can be safely handled by DMA. flush_dma_descr - Flush one DMA descriptor. flush_dma_list - Flush a complete list of DMA descriptors. cris_flush_cache - Flush the complete cache. cris_flush_cache_range - Flush only the specified range Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | define new percpu interface for shared dataFenghua Yu2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

* [PATCH] MSI-X: fix resume crashEric W. Biederman2007-03-28
| | | | | | | | | | | | | | So I think the right solution is to simply make pci_enable_device just flip enable bits and move the rest of the work someplace else. However a thorough cleanup is a little extreme for this point in the release cycle, so I think a quick hack that makes the code not stomp the irq when msi irq's are enabled should be the first fix.

Since __cpuinit would map to __init with this kind of a configuration, we get a .text refering .init.data warning. This patch solves the problem by converting all of __cpu_up, _cpu_up and cpu_up from __devinit to __cpuinit. The approach is justified since the callers of cpu_up are either dependent on CONFIG_HOTPLUG_CPU or are of __init type. Thus when CONFIG_HOTPLUG_CPU=y, all these cpu up functions would land up in .text section, and when CONFIG_HOTPLUG_CPU=n, all these functions would land up in .init section.

Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies.

* / [PATCH] genirq: rename desc->handler to desc->chipIngo Molnar2006-06-29
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch-queue improves the generic IRQ layer to be truly generic, by adding various abstractions and features to it, without impacting existing functionality. While the queue can be best described as "fix and improve everything in the generic IRQ layer that we could think of", and thus it consists of many smaller features and lots of cleanups, the one feature that stands out most is the new 'irq chip' abstraction. The irq-chip abstraction is about describing and coding and IRQ controller driver by mapping its raw hardware capabilities [and quirks, if needed] in a straightforward way, without having to think about "IRQ flow" (level/edge/etc.) type of details. This stands in contrast with the current 'irq-type' model of genirq architectures, which 'mixes' raw hardware capabilities with 'flow' details. The patchset supports both types of irq controller designs at once, and converts i386 and x86_64 to the new irq-chip design. As a bonus side-effect of the irq-chip approach, chained interrupt controllers (master/slave PIC constructs, etc.) are now supported by design as well. The end result of this patchset intends to be simpler architecture-level code and more consolidation between architectures. We reused many bits of code and many concepts from Russell King's ARM IRQ layer, the merging of which was one of the motivations for this patchset. This patch: rename desc->handler to desc->chip. Originally i did not want to do this, because it's a big patch. But having both "desc->handler", "desc->handle_irq" and "action->handler" caused a large degree of confusion and made the code appear alot less clean than it truly is. I have also attempted a dual approach as well by introducing a desc->chip alias - but that just wasnt robust enough and broke frequently. So lets get over with this quickly. The conversion was done automatically via scripts and converts all the code in the kernel. This renaming patch is the first one amongst the patches, so that the remaining patches can stay flexible and can be merged and split up without having some big monolithic patch act as a merge barrier.

* [PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHMChristoph Lameter2006-06-25
| | | | | | | | | | | | | | | | | Remove VM_LOCKED before remap_pfn range from device drivers and get rid of VM_SHM. remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not place pages on the LRU. The pages are therefore never subject to swap anyways. Remove all the vm_flags settings before calling remap_pfn_range. After removing all the vm_flag settings no use of VM_SHM is left. Drop it.

* [PATCH] set_page_dirty() return value fixesAndrew Morton2006-03-24
| | | | | | | | | | | | We need set_page_dirty() to return true if it actually transitioned the page from a clean to dirty state. This wasn't right in a couple of places. Do a kernel-wide audit, fix things up. This leaves open the possibility of returning a negative errno from set_page_dirty() sometime in the future. But we don't do that at present.
