2011-04-01powerpc/smp: Remove unused generic_cpu_enable()Benjamin Herrenschmidt2-23/+0
Nobody uses it, besides we should always use the normal __cpu_up path anyways Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-04-01powerpc/smp: Fix generic_mach_cpu_die()Benjamin Herrenschmidt1-2/+1
This is used by some "soft" hotplug implementations. I needs to call idle_task_exit() when the CPU is going away, and we remove the now no-longer needed set_cpu_online() and local_irq_enable() which are handled by the return to start_secondary Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-04-01powerpc/smp: soft-replugged CPUs must go back to start_secondaryBenjamin Herrenschmidt4-4/+17
Various thing are torn down when a CPU is hot-unplugged. That CPU is expected to go back to start_secondary when re-plugged to re initialize everything, such as clock sources, maps, ... Some implementations just return from cpu_die() callback in the idle loop when the CPU is "re-plugged". This is not enough. We fix it using a little asm trampoline which resets the stack and calls back into start_secondary as if we were all fresh from boot. The trampoline already existed on ppc64, but we add it for ppc32 Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-04-01powerpc: Make decrementer interrupt robust against offlined CPUsBenjamin Herrenschmidt1-4/+11
With some implementations, it is possible that a timer interrupt occurs every few seconds on an offline CPU. In this case, just re-arm the decrementer and return immediately Signed-off-by: Benjamin Herrenschmidt <[email protected]>

2011-03-31mlx4: Fixing bad size of event queue bufferYevgeny Petrilin1-1/+3
We should reduce the number of reserved completion queues from the total number of entries. Since the queue size is power of two, not reducing the reserved entries, caused a double queue size, which may lead to allocation failures in some cases.

2011-03-30sparc64: Fix section mis-match errors.David S. Miller11-14/+14
Fix all of the problems spotted by CONFIG_DEBUG_SECTION_MISMATCH under arch/sparc during a 64-bit defconfig build. They fall into two categorites: 1) of_device_id is marked as __initdata, and we can never do this since these objects sit in the device core data structures way past boot. So even if a driver will never be reloaded, we have to keep the device ID table around. Mark such cases const instead. 2) The bootmem alloc/free handling code in mdesc.c was not fully marked __init as it should be, thus generating a reference to free_bootmem_late() (which is __init) from non-__init code.

2011-03-30connector: convert to synchronous netlink message processingPatrick McHardy3-89/+32
Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms) and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct netlink_skb_parms) removed some members from struct netlink_skb_parms that depend on the current context, all netlink users are now required to do synchronous message processing. connector however queues received messages and processes them in a work queue, which is not valid anymore. This patch converts connector to do synchronous message processing by invoking the registered callback handler directly from the netlink receive function. In order to avoid invoking the callback with connector locks held, a reference count is added to struct cn_callback_entry, the reference is taken when finding a matching callback entry on the device's queue_list and released after the callback handler has been invoked.

2011-03-30atm/solos-pci: Don't flap VCs when carrier state changesPhilip A. Prindeville3-25/+3
Don't flap VCs when carrier state changes; higher-level protocols can detect loss of connectivity and act accordingly. This is more consistent with how other network interfaces work. We no longer use release_vccs() so we can delete it. release_vccs() was duplicated from net/atm/common.c; make the corresponding function exported, since other code duplicates it and could leverage it if it were public.

According to Thomas, the former is the correct direct conversion, but it does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c seems to initialize both to the same thing), and the chip data in some ways is the more logical. Somebody should really decide on one of the other. This merge picks irq_desc_get_handler_data() as the straightforward pure conversion to new names, as per Thomas.

2011-03-30netdev: fix mtu check when TSO is enabledDaniel Lezcano1-2/+22
In case the device where is coming from the packet has TSO enabled, we should not check the mtu size value as this one could be bigger than the expected value. This is the case for the macvlan driver when the lower device has TSO enabled. The macvlan inherit this feature and forward the packets without fragmenting them. Then the packets go through dev_forward_skb and are dropped. This patch fix this by checking TSO is not enabled when we want to check the mtu size.

2011-03-30net/usb: Ethernet quirks for the LG-VL600 4G modemAndrzej Zaborowski6-9/+387
This adds a driver for the CDC Ethernet part of this modem. The device's ID is blacklisted in cdc_ether.c and is white-listed in this new driver because of the quirks needed to make it useful. The modem's firmware exposes a CDC ACM port for modem control and a CDC Ethernet port for network data. The descriptors look fine but both ports actually are some sort of multiplexers requiring non- standard headers added/removed from every packet or they get ignored. All information is based on a usb traffic log from a Windows machine. On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps. Userspace scripts are required to talk to the CDC ACM port. Signed-off-by: Andrzej Zaborowski <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2011-03-30bridge: mcast snooping, fix length check of snooped MLDv1/2Linus Lüssing1-1/+1
"len = ntohs(ip6h->payload_len)" does not include the length of the ipv6 header itself, which the rest of this function assumes, though. This leads to a length check less restrictive as it should be in the following line for one thing. For another, it very likely leads to an integer underrun when substracting the offset and therefore to a very high new value of 'len' due to its unsignedness.

2011-03-30via-ircc: Use pci_{get, set}_drvdata() instead of static pointer variableBen Hutchings1-67/+15
via-ircc still maintains its own array of device pointers in Linux 2.4 style. Worse, it always uses index 0, so it will crash if there are multiple suitable devices in the system. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2011-03-30net: gre: provide multicast mappings for ipv4 and ipv6Timo Teräs4-0/+29
My commit 6d55cb91a0020ac0 (gre: fix hard header destination address checking) broke multicast. The reason is that ip_gre used to get ipgre_header() calls with zero destination if we have NOARP or multicast destination. Instead the actual target was decided at ipgre_tunnel_xmit() time based on per-protocol dissection. Instead of allowing the "abuse" of ->header() calls with invalid destination, this creates multicast mappings for ip_gre. This also fixes "ip neigh show nud noarp" to display the proper multicast mappings used by the gre device.

2011-03-30ALSA: firewire-speakers: fix hang when unplugging a running deviceClemens Ladisch1-2/+1
When aborting a PCM stream, the xrun is signaled only if the stream is running. When disconnecting a PCM stream, calling snd_card_disconnect() too early would change the stream into a non-running state and thus prevent the xrun from being noticed by user space. To prevent this, move the snd_card_disconnect() call after the xrun. Signed-off-by: Clemens Ladisch <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>

2011-03-29net: Fix warnings caused by MAX_SKB_FRAGS change.David S. Miller1-1/+1
After commit a715dea3c8e9ef2771c534e05ee1d36f65987e64 ("net: Always allocate at least 16 skb frags regardless of page size"), the value of MAX_SKB_FRAGS can now take on either an "unsigned long" or an "int" value. This causes warnings like: net/packet/af_packet.c: In function ‘tpacket_fill_skb’: net/packet/af_packet.c:948: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 2 has type ‘int’ Fix by forcing the constant to be unsigned long, otherwise we have a situation where the type of a system wide constant is variable.

2011-03-30nilfs2: fix data loss in mmap page write for hole blocksRyusuke Konishi1-6/+5
From the result of a function test of mmap, mmap write to shared pages turned out to be broken for hole blocks. It doesn't write out filled blocks and the data will be lost after umount. This is due to a bug that the target file is not queued for log writer when filling hole blocks. Also, nilfs_page_mkwrite function exits normal code path even after successfully filled hole blocks due to a change of block_page_mkwrite function; just after nilfs was merged into the mainline, block_page_mkwrite() started to return VM_FAULT_LOCKED instead of zero by the patch "mm: close page_mkwrite races" (commit: b827e496c893de0c). The current nilfs_page_mkwrite() is not handling this value properly. This corrects nilfs_page_mkwrite() and will resolve the data loss problem in mmap write. [This should be applied to every kernel since 2.6.30 but a fix is needed for 2.6.37 and prior kernels] Signed-off-by: Ryusuke Konishi <[email protected]> Tested-by: Ryusuke Konishi <[email protected]> Cc: stable <[email protected]> [2.6.38]
