Also, using per-cpu allocations for the thread-groups complicates the per-cpu allocator in that its currently aimed to be a fixed sized allocator and the only possible extention to that would be vmap based, which is seriously constrained on 32 bit archs. So making the per-cpu memory requirement depend on the number of processes is an issue. Lastly, it didn't deal with cpu-hotplug, although admittedly that might be fixable.

These pointers are set to NULL as soon as the corresponding descriptor has been submitted to the channel (in dma_run_dependencies()). But, the first 'next' in chain is still remaining set, regardless the fact, that tx->next has been already submitted. This may lead to multiple submissions of the same descriptor. This patch fixes this. Actually, some previous implementation of the xxx_run_dependencies() function already had this fix in place. The fdb..0eaf3 commit, beside the correct things, broke this.

Alsa should now be using the ASoC driver. For boards not yet using ASoC, please see sound/soc/omap/osk5912.c. Add dummy aic23_power_up and aic23_power_down functions for 770 to keep things compiling. Remove references to omap_gpio_switch, and unused h2_nand_dev_ready function. This patch is based on an earlier patch by Arun KS.

The script was originally written by Arnd Bergman and exten by me to cover a few more files. When the header files differed the script uses the following: The original m68k file is named _mm.h [mm for memory manager] The m68knommu file is named _no.h [no for no memory manager] The files uses the following include guard: This include gaurd works as the m68knommu toolchain set the __uClinux__ symbol - so this should work in userspace too. Merging the header files for m68k and m68knommu exposes the (unexpected?) ABI differences thus it is easier to actually identify these and thus to fix them. The commit has been build tested with both a m68k and a m68knommu toolchain - with success. The commit has also been tested with "make headers_check" and this patch fixes make headers_check for m68knommu.

This has caused weird boot failures in kmap_atomic much later in the boot process (initial userspace faults) on a 32-bit PAE system with a larger number of CPUs (smaller CPU counts tend not to run over into the next page so don't show up the problem). Solve this by attempting to clear out the page table, and copy any of its entries to the new one. Also, add a bug if a nonlinear condition is encountered and can't be resolved, which might save some hours of debugging if this fragile scheme ever breaks again... Once we have such logic, we can also use it to eliminate the early ioremap trickery around the page table setup for the fixmap area. This also fixes potential issues with FIX_* entries sharing the leaf page table with the early ioremap ones getting discarded by early_ioremap_clear() and not restored by early_ioremap_reset(). It at once eliminates the temporary (and configuration, namely NR_CPUS, dependent) unavailability of early fixed mappings during the time the fixmap area page tables get constructed. Finally, also replace the hard coded calculation of the initial table space needed for the fixmap area with a proper one, allowing kernels configured for large CPU counts to actually boot.

This is important because filesystem callbacks aren't called from under dqptr_sem which used to cause *lots* of problems with lock ranking (and with OCFS2 they became close to unsolvable). The patch also removes two functions which were introduced solely because OCFS2 needed them to cope with the old locking scheme. As time showed, they were not enough for OCFS2 anyway and it would be unnecessary work to adapt them to the new locking scheme in which they aren't needed. As a result OCFS2 needs the following patch to compile properly with quotas. Sorry to any bisecters which hit this in advance.

Wysocki" Date: Fri, 16 Jan 2009 21:54:43 +0100 Subject: [PATCH 050/805] PCI PM: Restore standard config registers of all devices early There is a problem in our handling of suspend-resume of PCI devices that many of them have their standard config registers restored with interrupts enabled and they are put into the full power state with interrupts enabled as well. This may lead to the following scenario: * an interrupt vector is shared between two or more devices * one device is resumed earlier and generates an interrupt * the interrupt handler of another device tries to handle it and attempts to access the device the config space of which hasn't been restored yet and/or which still is in a low power state * the system crashes as a result To prevent this from happening we should restore the standard configuration registers of all devices with interrupts disabled and we should put them into the D0 power state right after that. Unfortunately, this cannot be done using the existing pci_set_power_state(), because it can sleep.

The issue is that IEEE-802.11 allows APs to send a subset of what a country regulatory domain defines. This was clarified in this document: http://tinyurl.com/11d-clarification As such it is possible, and this is what is done in practice, that a single band 2.4 GHz AP will only send 2.4 GHz band regulatory information through the 802.11 country information element and then the current intersection with what CRDA provided yields a regulatory domain with no 5 GHz information -- even though that country may actually allow 5 GHz operation. We correct this by only applying the intersection rules on a channel if the the intersection yields a regulatory rule on the same band the channel is on. Signed-off-by: Luis R.

When running modprobe rt73usb, and then rmmod rt73usb, and then iwconfig, the wlan0 device does not disappear. When repeating this process again, we get a kernel Oops errors and "BUG: unable to handle kernel paging request..." message in the kernel log. The reason for this is that there is an error in rt2x00rfkill_free(), which is called in the process of removing the device (rt2x00lib_remove_dev() in rt2x00dev.c). rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is bit number 1 () in rt2x00dev->flags instead of in rt2x00dev->rfkill_state. As a result, when checking the DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call ieee80211_unregister_hw(). This patch corrects this: the parameter for __test_and_clear_bit() in rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not &rt2x00dev->flags.

Add a debug check to test this theory. If it triggers then it triggers because the resume code calls it with irqs enabled, which is a no-no not just for timekeeping_resume(), but also bad for a number of other resume handlers.

CM contains, among other blocks, an Interrupt Generator (IG) and a Clock and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are supported over dmaengine and irq-chip APIs respectively. IDMAC is a specialised DMA controller, its DMA channels cannot be used for general-purpose operations, even though it might be possible to configure a memory-to-memory channel for memcpy operation. This driver will not work with generic dmaengine clients, clients, wishing to use it must use respective wrapper structures, they also must specify which channels they require, as channels are hard-wired to specific IPU functions.

If the kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y on the make command line, arch/x86/mm/init_64.c is compiled with the -fno-inline-functions-called-once gcc option defeating inlining of kernel_physical_mapping_init() within init_memory_mapping(). When kernel_physical_mapping_init() is not inlined it is placed in the .init.text section according to the __init in it's current declaration. A later call to kernel_physical_mapping_init() during a memory hotplug operation encounters an int3 trap because the .init.text section memory has been freed. This patch eliminates the crash caused by the int3 trap by moving the non-inlined kernel_physical_mapping_init() from .init.text to .meminit.text.

This happens then the TGO (transfer ongoing) bit in the TSR is set (and UND). It seems like clening up after the underrun makes the driver and the macb hardware end up in an inconsistent state. The result of this is that in the following calls to macb_tx no TX buffers are released -> the netif_queue was stopped, and never woken up again. The solution is to disable the transmitter, if TGO is set, before clening up after the underrun, and re-enable the transmitter when the cleaning up is done.

The patch starts by consolidating David Woodhouse's earlier patch under the same name. Specifically, the patch moves the request_firmware call into a separate tg3_request_firmware() function and calls that function from tg3_open() rather than tg3_init_one(). The patch then goes on to limit the number of devices that will make request_firmware calls. The original firmware patch unnecessarily requested TSO firmware for devices that did not need it. This patch reduces the set of devices making TSO firmware patches to approximately the following device set : 5703, 5704, and 5705. Finally, the patch reduces the effects of a request_firmware() failure. For those devices that are requesting TSO firmware, the driver will turn off the TSO capability. If TSO firmware becomes available at a later time, the device can be closed and then opened again to reacquire the TSO capability.

The trick in socket splicing where we try to convert the skb->data into a page based reference using virt_to_page() does not work so well. The idea is to pass the virt_to_page() reference via the pipe buffer, and refcount the buffer using a SKB reference. But if we are splicing from a socket to a socket (via sendpage) this doesn't work. The from side processing will grab the page (and SKB) references. The sendpage() calls will grab page references only, return, and then the from side processing completes and drops the SKB ref. The page based reference to skb->data is not enough to keep the kmalloc() buffer backing it from being reused. Yet, that is all that the socket send side has at this point. This leads to data corruption if the skb->data buffer is reused by SLAB before the send side socket actually gets the TX packet out to the device. The fix employed here is to simply allocate a page and copy the skb->data bytes into that page. This will hurt performance, but there is no clear way to fix this properly without a copy at the present time, and it is important to get rid of the data corruption. With fixes from Herbert Xu.

Therefore, also write zeroes to the extended interrupt mask register when shutting down the port. This fixes the interrupt storm seen on the Pegasos board when shutting down the interface.

He provided a fix where it was replaced to kfree_skb(), as it should be. However, in i2400mu_rx(), the error path was missing returning an indication of the failure. Changed to reset rx_skb to NULL and return it to the caller, i2400mu_rxd(). It will be treated as a transient error and just ignore the packet. Depending on the buffering conditions inside the device, the data packet might be dropped or the device will signal the host again for data-ready-to-read and the host will retry.

If the calculation is incorrect, then the commits will never take place and the buffer will simply fill up and report an error. Each page in the ring buffer has a small header: struct buffer_data_page { u64 time_stamp; local_t commit; unsigned char data[]; }; Unfortuntely, some of the calculations used sizeof(struct buffer_data_page) to know the size of the header. But this is incorrect on some archs, where sizeof(struct buffer_data_page) does not equal offsetof(struct buffer_data_page, data), and on those archs, the commits are never processed.

If there happened bus resets without self ID complete events in the meantime, or self ID complete events with invalid selfIDs, the topology comparison could identify nodes wrongly, or more likely just corrupt kernel memory or panic right away. We now discard all nodes of the old topology and treat all current nodes as new ones if the current self ID generation is not the previous one plus 1.

Until now, firewire-core reported affected nodes as lost to the highlevel drivers (firewire-sbp2 and userspace drivers). We now delay the destruction of device representations until after at least two seconds after the last bus reset. If a "new" device is detected in this period whose bus information block and root directory header match that of a device which is pending for deletion, we resurrect that device and send update calls to highlevel drivers.
