This patch fixes a fairly serious tlb flushing bug that makes aio use under uml very unreliable -- SEGVs, Oops and panic()s occur as a result of stale tlb entires being used by uml when aio switches mms due to the fact that uml does not implement the activate_mm() hook. This patch introduces a simple but correct approach (read: hammer) for implementing activate_mm() in uml by doing a force_flush_all() if the new mm is different from old. With this patch in place, uml is able to succeed at the aio test case that was randomly faulting for me before. Cc: Jeff Dike <jdike@addtoit.com> Cc: <blaisorblade@yahoo.it> Signed-off-by:

mm/filemap_xip.c: In function `__xip_unmap': mm/filemap_xip.c:194: request for member `pte' in something not a structure or union Apparently pte_pfn() takes a pte_t, not a pointer to a pte_t. From looking at asm/page.h, it seems to be the same on ia32 or ppc (iff STRICT_MM_TYPECHECKS is enabled, which is disabled by default on ppc). Acked-by:

The current CardBus window allocation code in yenta_socket is unable to handle the transparent PCI-bridge handling update in 2.6.13. We need to check _all_ resources of a given type to find the best one suitable for CardBus windows, not just the first one. Signed-off-by:

Dominik Brodowski authored
If the CardBus windows were pre-configured and the CardBus bridge is behind a transparent PCI-PCI bridge, pci_find_parent_resource() might return a different resource than the real parent if it is called before the window is determined. Therefore, move that call around. Also fix return of value in void function. Signed-off-by:

Bug symptoms ~~~~~~~~~~~~ For the same inode VFS calls read_inode() twice and doesn't call clear_inode() between the two read_inode() invocations. Bug description ~~~~~~~~~~~~~~~ Suppose we have an inode which has zero reference count but is still in the inode cache. Suppose kswapd invokes shrink_icache_memory() to free some RAM. In prune_icache() inodes are removed from i_hash. prune_icache () is then going to call clear_inode(), but drops the inode_lock spinlock before this. If in this moment another task calls iget() for an inode which was just removed from i_hash by prune_icache(), then iget() invokes read_inode() for this inode, because it is *already removed* from i_hash. The end result is: we call iget(#N) then iput(#N); inode #N has zero i_count now and is in the inode cache; kswapd starts. kswapd removes the inode #N from i_hash ans is preempted; we call iget(#N) again; read_inode() is invoked as the result; but we expect clear_inode() before. Fix ~~~~~~~ To fix the bug I remove inodes from i_hash later, when clear_inode() is actually called. I remove them from i_hash under spinlock protection. Since the i_state is set to I_FREEING, it is safe to do this. The others will sleep waiting for the inode state change. I also postpone removing inodes from i_sb_list. It is not compulsory to do so but I do it for readability reasons. Inodes are added/removed to the lists together everywhere in the code and there is no point to change this rule. This is harmless because the only user of i_sb_list which somehow may interfere with me (invalidate_list()) is excluded by the iprune_sem mutex. The same race is possible in invalidate_list() so I do the same for it. Acked-by:

This patch fixes queer behavior in __wait_on_freeing_inode(). If I_LOCK was not set it called yield(), effectively busy waiting for the removal of the inode from the hash. This change was introduced within "[PATCH] eliminate inode waitqueue hashtable" Changeset 1.1938.166.16 last october by wli. The solution is to restore the old behavior, of unconditionally waiting on the waitqueue. It doesn't matter if I_LOCK is not set initally, the task will go to sleep, and wake up when wake_up_inode() is called from generic_delete_inode() after removing the inode from the hash chain. Comment is also updated to better reflect current behavior. This condition is very hard to trigger normally (simultaneous clear_inode() with iget()) so probably only heavy stress testing can reveal any change of behavior. Signed-off-by:

OK, I can see what's happening here. eth0 doesn't detect link-up until after a few seconds, so when the vlan interface is opened immediately after eth0 has been opened, it inherits the link-down state. Subsequently the vlan interface is never properly activated and are thus unable to transmit any packets. dev->state bits are not supposed to be manipulated directly. Something similar is probably needed for the netif_device_present() bit, although I don't know how this is meant to work for a virtual device. Signed-off-by:David S. Miller <davem@davemloft.net>

The following driver provides complete interrupt-in and interrupt-out reports (raw data) to a user program. Until now it uses the HIDIOCGDEVINFO ioctl call, because I don't know better :-(. Perhaps, it will be ok for you - and I will be happy, if you assign 8 minor numbers. I have tested it in several environments and it works very well for me. However, it has a problem with two or more devices at the same hub, if the two or more devices need 1 ms interrupt-in transfers. Unfortunately more than one interrupt-in transfer every ms isn't possible (ehci driver?). This is why the min_interrupt_in_interval and min_interrupt_out_interval are increased to 2 ms (see the corresponding module parameters). This way, I can use two devices simultaneously at the same hub. Signed-off-by:

The recent "pm_message_t" changes removed functionality from the Linux PM framework. This patch removes it from the OMAP OHCI too, removing the distinction between (previous) PM_SUSPEND_MEM and PM_SUSPEND_DISK state transitions ... now the only suspend semantics supportable are what was previously PM_SUSPEND_DISK (4) and is now "PMSG_SUSPEND" (3).

This driver is a basic keypress input driver for the Keyspan Digital Remote with part number UIA-11. Currently there is an older remote with part number UIA-10 which isn't supported by this driver. Support for the older UIA-10 could be added but a binary file is required to be download to the device, and I don't have that file. I also don't have a UIA-10 device so I wouldn't be able to test any of the changes. Signed-off-by:

Make usbmon to print Setup packets of Control transfers. This is useful when debugging enumeration issues. This is a change to the trace format which is not fully compatible. A parser has to look at the data length word now. If that word is a character like 's', read setup packet before proceeding with data. I decided not to bump the API tag for this because not many such parsers exist at this point. Signed-off-by:
