2014-07-22ASoC: Move card field form platform/codec to componentLars-Peter Clausen10-24/+24
Both the snd_soc_codec and snd_soc_platform struct do have a pointer to the parent card and both handle this pointer in mostly the same way. This patch moves the card field to the component level which will allow further code consolidation between platforms and CODECS. Since there are only a handful of users of the snd_soc_codec struct's card field (and none of the snd_soc_platform's) these are update in this patch as well, which allows it to be removed from the snd_soc_codec struct.

2014-07-22ASoC: tegra: Replace instances of rtd->codec->card with rtd->cardLars-Peter Clausen6-16/+10
No need to go via the CODEC to get a pointer to the card. This will help to eventually remove the card field from the snd_soc_codec struct. Signed-off-by: Lars-Peter Clausen <[email protected]> Signed-off-by: Mark Brown <[email protected]>

This commit is for correction of my misunderstanding about return value of .put callback in ALSA Control interface. According to 'Writing ALSA Driver' (*1), return value of the callback has three patterns; 1: changed, 0: not changed, an negative value: fatal error. But I misunderstood that it's boolean; zero or nonzero. *1: Writing an ALSA Driver (2005, Takashi Iwai) http://www.alsa-project.org/main/index.php/ALSA_Driver_Documentation Signed-off-by: Takashi Sakamoto <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
2014-07-22ALSA: bebob: Use different labels for digital input/outputTakashi Sakamoto1-7/+16
This commit uses different labels for control elements of digital input/output interfaces to correct my misunderstanding about M-Audio Firewire 1814 and ProjectMix I/O. According to user manuals for these two models, they have two modes for digital input; one is S/PDIF in both of optical and coaxial interfaces, another is ADAT in optical interface only. But in current implementation, a control element for it reduced labels which a control element for digital output uses because of my misunderstanding that optical interface is not available for digital input with S/PDIF mode.

2014-07-22x86_32, entry: Store badsys error code in %eaxSven Wegener1-4/+5
Commit 554086d ("x86_32, entry: Do syscall exit work on badsys (CVE-2014-4508)") introduced a regression in the x86_32 syscall entry code, resulting in syscall() not returning proper errors for undefined syscalls on CPUs supporting the sysenter feature. The following code: > int result = syscall(666); > printf("result=%d errno=%d error=%s\n", result, errno, strerror(errno)); results in: > result=666 errno=0 error=Success Obviously, the syscall return value is the called syscall number, but it should have been an ENOSYS error. When run under ptrace it behaves correctly, which makes it hard to debug in the wild: > result=-1 errno=38 error=Function not implemented The %eax register is the return value register. For debugging via ptrace the syscall entry code stores the complete register context on the stack. The badsys handlers only store the ENOSYS error code in the ptrace register set and do not set %eax like a regular syscall handler would. The old resume_userspace call chain contains code that clobbers %eax and it restores %eax from the ptrace registers afterwards. The same goes for the ptrace-enabled call chain. When ptrace is not used, the syscall return value is the passed-in syscall number from the untouched %eax register. Use %eax as the return value register in syscall_badsys and sysenter_badsys, like a real syscall handler does, and have the caller push the value onto the stack for ptrace access.

2014-07-22drm/i915: fix freeze with blank screen booting highmemHugh Dickins1-2/+2
x86_64 boots and displays fine, but booting x86_32 with CONFIG_HIGHMEM has frozen with a blank screen throughout 3.16-rc on this ThinkPad T420s, with i915 generation 6 graphics. Fix 9d0a6fa6c5e6 ("drm/i915: add render state initialization"): kunmap() takes struct page * argument, not virtual address. Which the compiler kindly points out, if you use the appropriate u32 *batch, instead of silencing it with a void *. Why did bisection lead decisively to nearby 229b0489aa75 ("drm/i915: add null render states for gen6, gen7 and gen8")? Because the u32 deposited at that virtual address by the previous stub failed the PageHighMem test, and so did no harm.

2014-07-22powerpc: use _GLOBAL_TOC for memmoveLi Zhong1-1/+1
memmove may be called from module code copy_pages(btrfs), and it may call memcpy, which may call back to C code, so it needs to use _GLOBAL_TOC to set up r2 correctly.

2014-07-22powerpc/pseries: dynamically added OF nodes need to call of_node_initTyrel Datwyler2-0/+2
Commit 75b57ecf9 refactored device tree nodes to use kobjects such that they can be exposed via /sysfs. A secondary commit 0829f6d1f furthered this rework by moving the kobect initialization logic out of of_node_add into its own of_node_init function. The inital commit removed the existing kref_init calls in the pseries dlpar code with the assumption kobject initialization would occur in of_node_add. The second commit had the side effect of triggering a BUG_ON during DLPAR, migration and suspend/resume operations as a result of dynamically added nodes being uninitialized. This patch fixes this by adding of_node_init calls in place of the previously removed kref_init calls.

Antonio Quartulli says: ==================== pull request [net]: batman-adv 20140721 here you have two fixes that we have been testing for quite some time (this is why they arrived a bit late in the rc cycle). Patch 1) ensures that BLA packets get dropped and not forwarded to the mesh even if they reach batman-adv within QinQ frames. Forwarding them into the mesh means messing up with the TT database of other nodes which can generate all kind of unexpected behaviours during route computation. Patch 2) avoids a couple of race conditions triggered upon fast VLAN deletion-addition. Such race conditions are pretty dangerous because they not only create inconsistencies in the TT database of the nodes in the network, but such scenario is also unrecoverable (unless nodes are rebooted). ==================== Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: Fifth set of fixes for IIO in the 3.16 cycle. One nasty one that has been around a long time and a couple of non compliant ABI fixes. * The demux code used to split out desired channels for devices that only support reading sets of channels at one time had a bug where it was building it's conversion tables against the wrong bitmap resulting in it never actually demuxing anything. This is an old bug, but will be effecting an increasing number of drivers as it is often used to avoid some fiddly code in the individual drivers. * bma180 and mma8452 weren't obeying the ABI wrt to units for acceleration. Were in G rather than m/s^2. A little input check was missing from bma180 that might lead to acceptance of incorrect values. This last one is minor but might lead to incorrect userspace code working and problems in the future.

2014-07-21x86, MCE: Robustify mcheck_init_deviceBorislav Petkov1-4/+6
BorisO reports that misc_register() fails often on xen. The current code unregisters the CPU hotplug notifier in that case. If then a CPU is offlined and onlined back again, we end up with a second timer running on that CPU, leading to soft lockups and system hangs. So let's leave the hotcpu notifier always registered - even if mce_device_create failed for some cores and never unreg it so that we can deal with the timer handling accordingly.

2014-07-21tracing: Fix wraparound problems in "uptime" trace clockTony Luck2-5/+6
The "uptime" trace clock added in: commit 8aacf017b065a805d27467843490c976835eb4a5 tracing: Add "uptime" trace clock that uses jiffies has wraparound problems when the system has been up more than 1 hour 11 minutes and 34 seconds. It converts jiffies to nanoseconds using: (u64)jiffies_to_usecs(jiffy) * 1000ULL but since jiffies_to_usecs() only returns a 32-bit value, it truncates at 2^32 microseconds. An additional problem on 32-bit systems is that the argument is "unsigned long", so fixing the return value only helps until 2^32 jiffies (49.7 days on a HZ=1000 system). Avoid these problems by using jiffies_64 as our basis, and not converting to nanoseconds (we do convert to clock_t because user facing API must not be dependent on internal kernel HZ values).

2014-07-21batman-adv: fix TT VLAN inconsistency on VLAN re-addAntonio Quartulli3-14/+74
When a VLAN interface (on top of batX) is removed and re-added within a short timeframe TT does not have enough time to properly cleanup. This creates an internal TT state mismatch as the newly created softif_vlan will be initialized from scratch with a TT client count of zero (even if TT entries for this VLAN still exist). The resulting TT messages are bogus due to the counter / tt client listing mismatch, thus creating inconsistencies on every node in the network To fix this issue destroy_vlan() has to not free the VLAN object immediately but it has to be kept alive until all the TT entries for this VLAN have been removed. destroy_vlan() still removes the sysfs folder so that the user has the feeling that everything went fine. If the same VLAN is re-added before the old object is free'd, then the latter is resurrected and re-used. Implement such behaviour by increasing the reference counter of a softif_vlan object every time a new local TT entry for such VLAN is created and remove the object from the list only when all the TT entries have been destroyed.

This patch makes this function aware that the first frag and the header might share the same ring slot. That could happen if the first slot is bigger than PKT_PROT_LEN. Due to this the error path might release that slot twice or never, depending on the error scenario. xenvif_idx_release is also removed from xenvif_idx_unmap, and called separately.
