The stub driver expects to access the usb interface and usb device structures even if the device has been disconnected in the meantime. This change gets a reference to them in the stub probe function using usb_get_intf()/usb_get_dev() and drops them in the disconnect function. This fixes an oops observed with a Logic Controls Line display (0fa8:a030) which disconnects itself when it is reset: [ 1348.562274] BUG: unable to handle kernel paging request at 5f7433e5 [ 1348.562327] IP: [<c0393b02>] usb_lock_device_for_reset+0x22/0xd0 [ 1348.562374] *pde = 00000000 [ 1348.562397] Oops: 0000 [#1] [ 1348.562418] last sysfs file: /sys/devices/pci0000:00/0000:00:10.2/usb4/4-1/bConfigurationValue [ 1348.562454] Modules linked in: usbip vhci_hcd usbip_common_mod fbcon tileblit font bitblit softcursor serio_raw uvesafb pcspkr via_rng snd_via82xx gameport snd_ac97_codec ac97_bus snd_pcm_oss snd_mixer_oss snd_pcm snd_page_alloc snd_mpu401_uart snd_rawmidi snd_seq_oss snd_seq_midi_event snd_seq snd_timer snd_seq_device snd usbhid hid via_rhine soundcore mii igel_flash aufs pata_via [ 1348.562649] [ 1348.562670] Pid: 2855, comm: usbip_eh Not tainted (2.6.32 #23.37-ud-r113) M300C [ 1348.562704] EIP: 0060:[<c0393b02>] EFLAGS: 00010216 CPU: 0 [ 1348.562734] EIP is at usb_lock_device_for_reset+0x22/0xd0 [ 1348.562762] EAX: 5f7433cd EBX: 5f7433cd ECX: de293a5c EDX: dd326a00 [ 1348.562793] ESI: 5f7433cd EDI: 000400f6 EBP: cf43ff48 ESP: cf43ff38 [ 1348.562824] DS: 007b ES: 007b FS: 0000 GS: 00e0 SS: 0068 [ 1348.562854] Process usbip_eh (pid: 2855, ti=cf43e000 task=d2c7f230 task.ti=cf43e000) [ 1348.562884] Stack: [ 1348.562900] d6ec9960 de2939cc 5f7433cd 5f743431 cf43ff70 df8fd32f de2939cc d2c7f230 [ 1348.562940] <0> cf43ff70 00000282 00000282 de2939cc d2c7f230 d2c7f230 cf43ffa8 df84416d [ 1348.562987] <0> cf43ff88 d2c7f230 de293a24 d2c7f230 00000000 d2c7f230 c014e760 cf43ff94 [ 1348.563042] Call Trace: [ 1348.563073] [<df8fd32f>] ? stub_device_reset+0x3f/0x110 [usbip] [ 1348.563114] [<df84416d>] ? event_handler_loop+0xcd/0xe8 [usbip_common_mod] [ 1348.563156] [<c014e760>] ? autoremove_wake_function+0x0/0x50 [ 1348.563193] [<df843d80>] ? usbip_thread+0x0/0x60 [usbip_common_mod] [ 1348.563230] [<df843dd1>] ? usbip_thread+0x51/0x60 [usbip_common_mod] [ 1348.563265] [<c014e374>] ? kthread+0x74/0x80 [ 1348.563294] [<c014e300>] ? kthread+0x0/0x80 [ 1348.563326] [<c0103c47>] ? kernel_thread_helper+0x7/0x10 [ 1348.563351] Code: 00 e8 73 4d 00 00 5d c3 90 55 89 e5 83 ec 10 89 5d f4 89 75 f8 89 7d fc 0f 1f 44 00 00 8b 3d c0 2e 67 c0 81 c7 fa 00 00 00 89 c3 <8b> 40 18 89 d6 85 c0 75 15 b8 ed ff ff ff 8b 5d f4 8b 75 f8 8b [ 1348.563528] EIP: [<c0393b02>] usb_lock_device_for_reset+0x22/0xd0 SS:ESP 0068:cf43ff38 [ 1348.563570] CR2: 000000005f7433e5 [ 1348.563593] ---[ end trace 9c3f1e3a2e5299d9 ]--- Signed-off-by:

Lately, mailbox callbacks have been replaced by notifier block call chains, this needs to be changed in the users of mailbox, otherwise compilation will break due to missing parameters. For this new change to work, io_mbox_msg needs to be compatible with the notifier_call definition. Reported-by:

The ni_labpc driver module only requests a shared IRQ for PCI devices, requesting a non-shared IRQ for non-PCI devices. As this module is also used by the ni_labpc_cs module for certain National Instruments PCMCIA cards, it also needs to request a shared IRQ for PCMCIA devices, otherwise you get a IRQ mismatch with the CardBus controller.

IVA MMU can manage up to 4GB of address space through its page tables, given that it's L1 is divided into 1MB sections it requires at least 16KB for its table which represents 4096 entries of 32 bits each. Previously, only 1GB was being handled by setting the page table size to 4KB, any virtual address beyond of the L1 size used, would fall into memory that does not belong to L1 translation tables, leading to unpredictable results. So, set the L1 table size to cover the entire MMU range (4GB) whether is meant to be used or not. Reported-by:

The original code called input_free_device(rmi4_data->input_dev) after input_unregister_device(rmi4_data->input_dev) and that's a double free. This is described in the comments to input_unregister_device(). The normal way to handle this is to make input_register_device() the last function in the probe which can fail. That way you can avoid the call to input_unregister_device() entirely. Signed-off-by:

Removed the call to netif_stop_queue() in netvsc_probe() as the queue is not initialized at that point and further call to it after queue initialization is really not necessary. This change was prompted after an upstream change went into 2.6.37 (netif_tx_stop_queue) that now checks if netif_stop_queue is called before register with netdev is done. This will eliminate the warning message to the log when hv_netvsc driver starts up. Signed-off-by:

While most users of a physical Malta board are using the serial port as the console, a lot of QEMU users would prefer to interact with a graphical console. Enable the Cirrus FB support in the Malta default configuration to make that possible. Note that the default console will still be the serial port, users have to pass "console=tty0" to the kernel to use the Cirrus FB. Signed-off-by:

Just do what everyone else is doing by placing __read_mostly things in the .data.read_mostly section. mips_io_port_base can not be read-only (const) and writable (__read_mostly) at the same time. One of them has to go, so I chose to eliminate the __read_mostly. It will still get stuck in a portion of memory that is not adjacent to things that are written, and thus not be on a dirty cache line, for whatever that is worth. Signed-off-by:

This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches. Signed-off-by:

On the off chance that uasm ever warns about overflow, there is no way to know what the offending instruction is. Change the printks to WARNs, so we can get a nice stack trace. It has the added benefit of being much more noticeable than the short single line warning message, so is less likely to be ignored. Signed-off-by:
