The largest change here is the L2 changes to work around problems for the Armada 37x/380 devices, where most of the size comes down to comments rather than code. The other significant fix here is for the ptrace code, to ensure that rewritten syscalls work as intended. This was pointed out by Kees Cook, but Will Deacon reworked the patch to be more elegant. The remainder are fairly trivial changes" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: 8087/1: ptrace: reload syscall number after secure_computing() check ARM: 8086/1: Set memblock limit for nommu ARM: 8085/1: sa1100: collie: add top boot mtd partition ARM: 8084/1: sa1100: collie: revert back to cfi_probe ARM: 8080/1: mcpm.h: remove unused variable declaration ARM: 8076/1: mm: add support for HW coherent systems in PL310 cache 29 June 2014, 20:40:08 UTC

42309ab Will Deacon 27 June 2014, 16:01:47 UTC ARM: 8087/1: ptrace: reload syscall number after secure_computing() check On the syscall tracing path, we call out to secure_computing() to allow seccomp to check the syscall number being attempted. As part of this, a SIGTRAP may be sent to the tracer and the syscall could be re-written by a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall is ignored by the current code unless TIF_SYSCALL_TRACE is also set on the current thread. This patch slightly reworks the enter path of the syscall tracing code so that we always reload the syscall number from current_thread_info()->syscall after the potential ptrace traps.

98ea2db Thomas Petazzoni 13 June 2014, 09:58:38 UTC ARM: 8076/1: mm: add support for HW coherent systems in PL310 cache When a PL310 cache is used on a system that provides hardware coherency, the outer cache sync operation is useless, and can be skipped. Moreover, on some systems, it is harmful as it causes deadlocks between the Marvell coherency mechanism, the Marvell PCIe controller and the Cortex-A9. To avoid this, this commit introduces a new Device Tree property 'arm,io-coherent' for the L2 cache controller node, valid only for the PL310 cache. It identifies the usage of the PL310 cache in an I/O coherent configuration. Internally, it makes the driver disable the outer cache sync operation. Note that technically speaking, a fully coherent system wouldn't require any of the other .outer_cache operations. However, in practice, when booting secondary CPUs, these are not yet coherent, and therefore a set of cache maintenance operations are necessary at this point. This explains why we keep the other .outer_cache operations and only ->sync is disabled. While in theory any write to a PL310 register could cause the deadlock, in practice, disabling ->sync is sufficient to workaround the deadlock, since the other cache maintenance operations are only used in very specific situations. Contrary to previous versions of this patch, this new version does not simply NULL-ify the ->sync member, because the l2c_init_data structures are now 'const' and therefore cannot be modified, which is a good thing. Therefore, this patch introduces a separate l2c_init_data instance, called of_l2c310_coherent_data.

81a9c5e Mikulas Patocka 23 June 2014, 17:42:37 UTC iscsi-target: fix iscsit_del_np deadlock on unload On uniprocessor preemptible kernel, target core deadlocks on unload. The following events happen: * iscsit_del_np is called * it calls send_sig(SIGINT, np->np_thread, 1); * the scheduler switches to the np_thread * the np_thread is woken up, it sees that kthread_should_stop() returns false, so it doesn't terminate * the np_thread clears signals with flush_signals(current); and goes back to sleep in iscsit_accept_np * the scheduler switches back to iscsit_del_np * iscsit_del_np calls kthread_stop(np->np_thread); * the np_thread is waiting in iscsit_accept_np and it doesn't respond to kthread_stop The deadlock could be resolved if the administrator sends SIGINT signal to the np_thread with killall -INT iscsi_np The reproducible deadlock was introduced in commit db6077fd0b7dd41dc6ff18329cec979379071f87, but the thread-stopping code was racy even before. This patch fixes the problem. Using kthread_should_stop to stop the np_thread is unreliable, so we test np_thread_state instead. If np_thread_state equals ISCSI_NP_THREAD_SHUTDOWN, the thread exits.

Without that the id in the resulting pstore filename is wrong and userspace may have problems parsing it, but more importantly files in pstore can never be deleted and may fill the EFI flash (brick device?). This happens because when generic pstore code wants to delete a file, it passes the id to the EFI backend which reinterpretes it and a wrong variable name is attempted to be deleted. There's no error message but after remounting pstore, deleted files would reappear.

Make it use the non __ variant, which handles cases where we are called from the wrong CPU set. From me. - A fix for drbd, which allocates discard requests without room for the SCSI payload. From Lars Ellenberg. - A fix for user-after-free in the blkcg code from Tejun. - Addition of limiting gaps in SG lists, if the hardware needs it. This is the last pre-req patch for blk-mq to enable the full NVMe conversion.

0b86dbf Al Viro 23 June 2014, 07:44:40 UTC Fix 32-bit regression in block device read(2) blkdev_read_iter() wants to cap the iov_iter by the amount of data remaining to the end of device. That's what iov_iter_truncate() is for (trim iter->count if it's above the given limit). So far, so good, but the argument of iov_iter_truncate() is size_t, so on 32bit boxen (in case of a large device) we end up with that upper limit truncated down to 32 bits *before* comparing it with iter->count. Easily fixed by making iov_iter_truncate() take 64bit argument - it does the right thing after such change (we only reach the assignment in there when the current value of iter->count is greater than the limit, i.e. for anything that would get truncated we don't reach the assignment at all) and that argument is not the new value of iter->count - it's an upper limit for such. The overhead of passing u64 is not an issue - the thing is inlined, so callers passing size_t won't pay any penalty.

a07187c Mengdong Lin 26 June 2014, 10:45:16 UTC ALSA: hda - restore BCLK M/N values when resuming HSW/BDW display controller For Intel Haswell/Broadwell display HD-A controller, the 24MHz HD-A link BCLK is converted from Core Display Clock (CDCLK): BCLK = CDCLK * M / N And there are two registers EM4 and EM5 to program M, N value respectively. The EM4/EM5 values will be lost and when the display power well is disabled. BIOS programs CDCLK selected by OEM and EM4/EM5, but BIOS has no idea about display power well on/off at runtime. So the M/N can be wrong if non-default CDCLK is used when the audio controller resumes, which results in an invalid BCLK and abnormal audio playback rate. So this patch saves and restores valid M/N values on controller suspend/resume. And 'struct hda_intel' is defined to contain standard HD-A 'struct azx' and Intel specific fields, as Takashi suggested.

91ad11d Alex Smith 17 June 2014, 09:39:53 UTC recordmcount/MIPS: Fix possible incorrect mcount_loc table entries in modules On MIPS calls to _mcount in modules generate 2 instructions to load the _mcount address (and therefore 2 relocations). The mcount_loc table should only reference the first of these, so the second is filtered out by checking the relocation offset and ignoring ones that immediately follow the previous one seen. However if a module has an _mcount call at offset 0, the second relocation would not be filtered out due to old_r_offset == 0 being taken to mean that the current relocation is the first one seen, and both would end up in the mcount_loc table. This results in ftrace_make_nop() patching both (adjacent) instructions to branches over the _mcount call sequence like so: 0xffffffffc08a8000: 04 00 00 10 b 0xffffffffc08a8014 0xffffffffc08a8004: 04 00 00 10 b 0xffffffffc08a8018 0xffffffffc08a8008: 2d 08 e0 03 move at,ra ... The second branch is in the delay slot of the first, which is defined to be unpredictable - on the platform on which this bug was encountered, it triggers a reserved instruction exception. Fix by initializing old_r_offset to ~0 and using that instead of 0 to determine whether the current relocation is the first seen.

16f77de Paul Burton 18 June 2014, 14:00:46 UTC Revert "MIPS: Save/restore MSA context around signals" This reverts commit eec43a224cf1 "MIPS: Save/restore MSA context around signals" and the MSA parts of ca750649e08c "MIPS: kernel: signal: Prevent save/restore FPU context in user memory" (the restore path of which appears incorrect anyway...). The reverted patch took care not to break compatibility with userland users of struct sigcontext, but inadvertantly changed the offset of the uc_sigmask field of struct ucontext. Thus Linux v3.15 breaks the userland ABI. The MSA context will need to be saved via some other opt-in mechanism, but for now revert the change to reduce the fallout. This will have minimal impact upon use of MSA since the only supported CPU which includes it (the P5600) is 32-bit and therefore requires that the experimental CONFIG_MIPS_O32_FP64_SUPPORT Kconfig option be selected before the kernel will set FR=1 for a task, a requirement for MSA use. Thus the users of MSA are limited to known small groups of people & this patch won't be breaking any previously working MSA-using userland outside of experimental settings.

92a586b Takashi Iwai 25 June 2014, 12:24:47 UTC ALSA: usb-audio: Fix races at disconnection and PCM closing When a USB-audio device is disconnected while PCM is still running, we still see some race: the disconnect callback calls snd_usb_endpoint_free() that calls release_urbs() and then kfree() while a PCM stream would be closed at the same time and calls stop_endpoints() that leads to wait_clear_urbs(). That is, the EP object might be deallocated while a PCM stream is syncing with wait_clear_urbs() with the same EP. Basically calling multiple wait_clear_urbs() would work fine, also calling wait_clear_urbs() and release_urbs() would work, too, as wait_clear_urbs() just reads some fields in ep. The problem is the succeeding kfree() in snd_pcm_endpoint_free(). This patch moves out the EP deallocation into the later point, the destructor callback. At this stage, all PCMs must have been already closed, so it's safe to free the objects.

DST_NOCACHE dst were supposed to be freed from dst_release(). But it appears we want to keep such dst around, either in UDP sockets or tunnels. In sk_dst_get() we need to make sure dst refcount is not 0 before incrementing it, or else we might end up freeing a dst twice. DST_NOCACHE set on a dst does not mean this dst can not be attached to a socket or a tunnel. Then, before actual freeing, we need to observe a rcu grace period to make sure all other cpus can catch the fact the dst is no longer usable.

f7b50c4 Wei Liu 23 June 2014, 09:50:17 UTC xen-netback: bookkeep number of active queues in our own module The original code uses netdev->real_num_tx_queues to bookkeep number of queues and invokes netif_set_real_num_tx_queues to set the number of queues. However, netif_set_real_num_tx_queues doesn't allow real_num_tx_queues to be smaller than 1, which means setting the number to 0 will not work and real_num_tx_queues is untouched. This is bogus when xenvif_free is invoked before any number of queues is allocated. That function needs to iterate through all queues to free resources. Using the wrong number of queues results in NULL pointer dereference. So we bookkeep the number of queues in xen-netback to solve this problem. This fixes a regression introduced by multiqueue patchset in 3.16-rc1. There's another bug in original code that the real number of RX queues is never set. In current Xen multiqueue design, the number of TX queues and RX queues are in fact the same. We need to set the numbers of TX and RX queues to the same value. Also remove xenvif_select_queue and leave queue selection to core driver, as suggested by David Miller.

8b3dfda Takashi Iwai 24 June 2014, 11:55:25 UTC ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13 HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the default high-pass filter in some "safer" range, which results in the very soft tone from the built-in speakers in contrast to Windows. Also, the mute LED control is missing, since 92HD95 codec still has no HP-specific fixups for GPIO setups. This patch adds these missing features: the HPF is adjusted by the vendor-specific verb, and the LED is set up from a DMI string (but with the default polarity = 0 assumption due to the incomplete BIOS on the given machine).

0ffbce8 Jens Axboe 25 June 2014, 14:22:34 UTC blk-mq: blk_mq_start_hw_queue() should use blk_mq_run_hw_queue() Currently it calls __blk_mq_run_hw_queue(), which depends on the CPU placement being correct. This means it's not possible to call blk_mq_start_hw_queues(q) from a context that is correct for all queues, leading to triggering the WARN_ON(!cpumask_test_cpu(raw_smp_processor_id(), hctx->cpumask)); in __blk_mq_run_hw_queue().
