2011-11-08sunhme: Allow usage on SBI based SBus systemsoftedal1-1/+1
To prevent the SBus driver for Sun Happy Meal cards from being loaded for PCI cards utilizing the same chipset, a filter was added to the probe function in commit 0b492fce3d72d982a7981905f85484a1e1ba7fde. The filter was implemented by checking the name of the parent node in the OF tree. This patch extends this filter, so that the driver will load on SBus systems that are based upon SBI SBus Bridges.

2011-11-08n_gsm: Fix timingsAlan Cox1-5/+7
Alek Du reported that the code erroneously applies time to jiffies conversions twice to the t1 and t2 values. In normal use on a modem link this cases no visible problem but on a slower link it will break as with HZ=1000 as is typical we are running t1/t2 ten times too fast. Alek's original patch removed the conversion from the timer setting but we in fact have to be more careful as the contents of t1/t2 are visible via the device API and we thus need to correct the constants.

2011-11-08MIPS: Kernel hangs occasionally during boot.Al Cooper1-19/+19
The Kernel hangs occasionally during boot after "Calibrating delay loop..". This is caused by the c0_compare_int_usable() routine in cevt-r4k.c returning false which causes the system to disable the timer and hang later. The false return happens because the routine is using a series of four calls to irq_disable_hazard() as a delay while it waits for the timer changes to propagate to the cp0 cause register. On newer MIPS cores, like the 74K, the series of irq_disable_hazard() calls turn into ehb instructions and can take as little as a few clock ticks for all 4 instructions. This is not enough of a delay, so the routine thinks the timer is not working. This fix uses up to a max number of cycle counter ticks for the delay and uses back_to_back_c0_hazard() instead of irq_disable_hazard() to handle the hazard condition between cp0 writes and cp0 reads.

2011-11-08Fix incorrect usage of NET_IP_ALIGNNico Erfurth1-3/+4
The driver used NET_IP_ALIGN to remove some additional padding inside of the rx_fixup function. On many architectures NET_IP_ALIGN defaults to 2 which removed the correct amount of bytes. On MCORE2-machines commit ea812ca1b06113597adcd8e70c0f84a413d97544 introduces a change which sets NET_IP_ALIGN to 0 by default. Which triggered the bug on these machines. This fix introduces a new RXW_PADDING define and uses this instead of NET_IP_ALIGN. The name was taken from the original SMSC7500 driver which is provided by SMSC.

2011-11-08r8169: increase the delay parameter of pm_schedule_suspendhayeswang1-1/+1
The link down would occur when reseting PHY. And it would take about 2 ~ 5 seconds from link down to link up. If the delay of pm_schedule_suspend is not long enough, the device would enter runtime_suspend before link up. After link up, the device would wake up and reset PHY again. Then, you would find the driver keep in a loop of runtime_suspend and rumtime_resume.

2011-11-08ALSA: usb-audio - Fix the missing volume quirks at delayed initTakashi Iwai1-50/+59
In the recent usb-audio driver, the initialization of volume ranges may be delayed when the device doesn't respond well at the probing time. But the volume quirks for certain devices are applied only in mixer_ctl_feature_info() thus only at the very first probe and will be missing when the volume range is initialized later. This patch moves the volume quirk code to be always called from the volume-range extraction (get_min_max()), so that the quirks are properly applied in the later init time.

Fixes a possible memory corruption when the link is larger than MAXPATHLEN and XFS_DEBUG is not enabled. This also remove the S_ISLNK assert, since the inode mode is checked previously in xfs_readlink_by_handle() and via VFS. Updated to address concerns raised by Ben Hutchings about the loose attention paid to 32- vs 64-bit values, and the lack of handling a potentially negative pathlen value: - Changed type of "pathlen" to be xfs_fsize_t, to match that of ip->i_d.di_size - Added checking for a negative pathlen to the too-long pathlen test, and generalized the message that gets reported in that case to reflect the change As a result, if a negative pathlen were encountered, this function would return EFSCORRUPTED (and would fail an assertion for a debug build)--just as would a too-long pathlen.

2011-11-08x86/mce: Make mce_chrdev_ops 'static const'Luck, Tony3-5/+27
Arjan would like to make struct file_operations const, but mce-inject directly writes to the mce_chrdev_ops to install its write handler. In an ideal world mce-inject would have its own character device, but we have a sizable legacy of test scripts that hardwire "/dev/mcelog", so it would be painful to switch to a separate device now. Instead, this patch switches to a stub function in the mce code, with a registration helper that mce-inject can call when it is loaded. Note that this would also allow for a sane process to allow mce-inject to be unloaded again (with an unregister function, and appropriate module_{get,put}() calls), but that is left for potential future patches.

2011-11-08[media] v4l2-event: Don't set sev->fh to NULL on unsubscribeHans de Goede2-3/+2
Setting sev->fh to NULL causes problems for the del op added in the next patch of this series, since this op needs a way to get to its own data structures, and typically this will be done by using container_of on an embedded v4l2_fh struct. The reason the original code is setting sev->fh to NULL is to signal to users of the event framework that the unsubscription has happened, but since their is no shared lock between the event framework and users of it, this is inherently racy, and it also turns out to be unnecessary as long as both the event framework and the user of the framework do their own locking properly and the user guarantees that it holds no references to the subcribed_event structure after its del operation has been called. This is best explained by looking at the only code currently checking for sev->fh being set to NULL on unsubscribe, which is the v4l2-ctrls.c send_event function. Here is the relevant code from v4l2-ctrls: send_event(): if (sev->fh && (sev->fh != fh || (sev->flags & V4L2_EVENT_SUB_FL_ALLOW_FEEDBACK))) v4l2_event_queue_fh(sev->fh, &ev); Now lets say that v4l2_event_unsubscribe and v4l2-ctrls: send_event() race on the same sev, then the following could happens: 1) send_event checks sev->fh, finds it is not NULL <thread switch> 2) v4l2_event_unsubscribe sets sev->fh NULL 3) v4l2_event_unsubscribe calls v4l2_ctrls del_event function, this blocks as the thread calling send_event holds the ctrl_lock <thread switch> 4) send_event calls v4l2_event_queue_fh(sev->fh, &ev) which not is equivalent to calling: v4l2_event_queue_fh(NULL, &ev) 5) oops, NULL pointer deref. Now again without setting sev->fh to NULL in v4l2_event_unsubscribe and without the (now senseless since always true) sev->fh != NULL check in 1) send_event is about to call v4l2_event_queue_fh(sev->fh, &ev) <thread switch> 2) v4l2_event_unsubscribe removes sev->list from the fh->subscribed list <thread switch> 3) send_event calls v4l2_event_queue_fh(sev->fh, &ev) 4) v4l2_event_queue_fh blocks on the fh_lock spinlock <thread switch> 5) v4l2_event_unsubscribe unlocks the fh_lock spinlock 6) v4l2_event_unsubscribe calls v4l2_ctrls del_event function, this blocks as the thread calling send_event holds the ctrl_lock <thread switch> 8) v4l2_event_queue_fh takes the fh_lock 7) v4l2_event_queue_fh calls v4l2_event_subscribed, does not find it since sev->list has been removed from fh->subscribed already -> does nothing 9) v4l2_event_queue_fh releases the fh_lock 10) the caller of send_event releases the ctrl lock (mutex) <thread switch> 11) v4l2_ctrls del_event takes the ctrl lock 12) v4l2_ctrls del_event removes sev->node from the ev_subs list 13) v4l2_ctrls del_event releases the ctrl lock 14) v4l2_event_unsubscribe frees the sev, to which no references are being held anymore Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-11-08powerpc/ps3: irq: Remove IRQF_DISABLEDYong Zhang2-2/+2
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed.

2011-11-08powerpc/numa: NUMA topology support for PowerNVDipankar Sarma1-7/+17
This patch adds support for numa topology on powernv platforms running OPAL formware. It checks for the type of platform at run time and sets the affinity form correctly so that NUMA topology can be discovered correctly.

2011-11-08powerpc: Add System RAM to /proc/iomemAnton Blanchard1-0/+30
We've resisted adding System RAM to /proc/iomem because it is the wrong place for it. Unfortunately we continue to find tools that rely on this behaviour so give up and add it in. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
