commit 8a603f91 upstream. If the host toolchain is not glibc based then the arm kernel build fails with HOSTCC arch/arm/vdso/vdsomunge arch/arm/vdso/vdsomunge.c:48:22: fatal error: byteswap.h: No such file or directory Observed: with omap2plus_defconfig and compile on Mac OS X with arm ELF cross-compiler. Reason: byteswap.h is a glibc only header. Solution: replace by private byte-swapping macros (taken from arch/mips/boot/elf2ecoff.c and kindly improved by Russell King) Tested to compile on Mac OS X 10.9.5 host. Signed-off-by:

commit 1bd5dfe4 upstream. Commit 685e2d08 ("ARM: OMAP1: Change interrupt numbering for sparse IRQ") turned on SPARSE_IRQ on OMAP1, but forgot to change the number of INT_DMA_LCD. This broke the boot at least on Nokia 770, where the device hangs during framebuffer initialization. Fix by defining INT_DMA_LCD like the other interrupts.

commit 7e381ec6 upstream. LDO1 regulator (VDD_SD) is connected to SoC's vddshv8. vddshv8 needs to be kept always powered (see commit 5a0f93c6 ("ARM: dts: Add am57xx-beagle-x15"), but at the moment VDD_SD is enabled/disabled depending on whether an SD card is inserted or not. This patch sets LDO1 regulator to always-on. This patch has a side effect of fixing another issue, HDMI DDC not working when SD card is not inserted: Why this happens is that the tpd12s015 (HDMI level shifter/ESD protection chip) has LS_OE GPIO input, which needs to be enabled for the HDMI DDC to work. LS_OE comes from gpio6_28. The pin that provides gpio6_28 is powered by vddshv8, and vddshv8 comes from VDD_SD. So when SD card is not inserted, VDD_SD is disabled, and LS_OE stays off. The proper fix for the HDMI DDC issue would be to maybe have the pinctrl framework manage the pin specific power. Apparently this fixes also a third issue (copy paste from Kishon's patch): ldo1_reg in addition to being connected to the io lines is also connected to the card detect line. On card removal, omap_hsmmc driver does a regulator_disable causing card detect line to be pulled down. This raises a card insertion interrupt and once the MMC core detects there is no card inserted, it does a regulator disable which again raises a card insertion interrupt. This happens in a loop causing infinite MMC interrupts. Fixes: 5a0f93c6 ("ARM: dts: Add am57xx-beagle-x15") Cc: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by:

commit 51a6256b upstream. On each next iteration of for_each_compatible_node() the reference counter for current device node is already decreased by the loop iterator. The manual call to of_node_get() is required only on loop break which is not happening here. The double of_node_get() (with enabled CONFIG_OF_DYNAMIC) lead to decreasing the counter below expected, initial value.

commit 6d69bb53 upstream. Mapping an image with a long parent chain (e.g. image foo, whose parent is bar, whose parent is baz, etc) currently leads to a kernel stack overflow, due to the following recursion in the reply path: rbd_osd_req_callback() rbd_obj_request_complete() rbd_img_obj_callback() rbd_img_parent_read_callback() rbd_obj_request_complete() ... Limit the parent chain to 16 images, which is ~5K worth of stack. When the above recursion is eliminated, this limit can be lifted. Fixes: http://tracker.ceph.com/issues/12538Signed-off-by:

commit 1f2c6651 upstream. Currently we leak parent_spec and trigger a "parent reference underflow" warning if rbd_dev_create() in rbd_dev_probe_parent() fails. The problem is we take the !parent out_err branch and that only drops refcounts; parent_spec that would've been freed had we called rbd_dev_unparent() remains and triggers rbd_warn() in rbd_dev_parent_put() - at that point we have parent_spec != NULL and parent_ref == 0, so counter ends up being -1 after the decrement. Redo rbd_dev_probe_parent() to fix this. Signed-off-by:

commit bae818ee upstream. rbd requires stable pages, as it performs a crc of the page data before they are send to the OSDs. But since kernel 3.9 (patch 1d1d1a76 "mm: only enforce stable page writes if the backing device requires it") it is not assumed anymore that block devices require stable pages. This patch sets the necessary flag to get stable pages back for rbd. In a ceph installation that provides multiple ext4 formatted rbd devices "bad crc" messages appeared regularly (ca 1 message every 1-2 minutes on every OSD that provided the data for the rbd) in the OSD-logs before this patch. After this patch this messages are pretty much gone (only ca 1-2 / month / OSD). Signed-off-by:

commit cc917ab4 upstream. Pinning a userptr onto the hardware raises interesting questions about the lifetime of such a surface as the framebuffer extends that life beyond the client's address space. That is the hardware will need to keep scanning out from the backing storage even after the client wants to remap its address space. As the hardware pins the backing storage, the userptr becomes invalid and this raises a WARN when the clients tries to unmap its address space. The situation can be even more complicated when the buffer is passed between processes, between a client and display server, where the lifetime and hardware access is even more confusing. Deny it.

commit 40a24488 upstream. In order to flush the results from in-batch pipecontrol writes (used for example in glQuery) before declaring the batch complete (and so declaring the query results coherent), we need to set the FlushEnable bit in our flushing pipecontrol. The FlushEnable bit "waits until all previous writes of immediate data from post-sync circles are complete before executing the next command". I get GPU hangs on byt without flushing these writes (running ue4). piglit has examples where the flush is required for correct rendering. Signed-off-by:

commit 2a6c521b upstream. On nv50+, we restrict the valid domains to just the one where the buffer was originally created. However after the buffer is evicted to system memory, we might move it back to a different domain that was not originally valid. When sharing the buffer and retrieving its GEM_INFO data, we still want the domain that will be valid for this buffer in a pushbuf, not the one where it currently happens to be. This resolves fdo#92504 and several others. These are due to suspend evicting all buffers, making it more likely that they temporarily end up in the wrong place.

commit a2d76290 upstream. The stack tracer was triggering the WARN_ON() in module.c: static void module_assert_mutex_or_preempt(void) { #ifdef CONFIG_LOCKDEP if (unlikely(!debug_locks)) return; WARN_ON(!rcu_read_lock_sched_held() && !lockdep_is_held(&module_mutex)); #endif } The reason is that the stack tracer traces all function calls, and some of those calls happen while exiting or entering user space and idle. Some of these functions are called after RCU had already stopped watching, as RCU does not watch userspace or idle CPUs. If a max stack is hit, then the save_stack_trace() is called, which will check module addresses and call module_assert_mutex_or_preempt(), and then trigger the warning. Sad part is, the warning itself will also do a stack trace and tigger the same warning. That probably should be fixed. The warning was added by 0be964be "module: Sanitize RCU usage and locking" but this bug has probably been around longer. But it's unlikely to cause much harm, but the new warning causes the system to lock up. Cc: Peter Zijlstra <peterz@infradead.org> Cc:"Paul E. McKenney" <paulmck@linux.vnet.ibm.com> Signed-off-by:

commit 296291cd upstream. Currently a simple program below issues a sendfile(2) system call which takes about 62 days to complete in my test KVM instance. int fd; off_t off = 0; fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644); ftruncate(fd, 2); lseek(fd, 0, SEEK_END); sendfile(fd, fd, &off, 0xfffffff); Now you should not ask kernel to do a stupid stuff like copying 256MB in 2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin should have a way to stop you. We actually do have a check for fatal_signal_pending() in generic_perform_write() which triggers in this path however because we always succeed in writing something before the check is done, we return value > 0 from generic_perform_write() and thus the information about signal gets lost. Fix the problem by doing the signal check before writing anything. That way generic_perform_write() returns -EINTR, the error gets propagated up and the sendfile loop terminates early. Signed-off-by:

commit ababae44 upstream. Commit 4857c91f changed the way how irq affinity is setup in setup_ioapic_dest() from using the core helper function to unconditionally calling the irq_set_affinity() callback of the underlying irq chip. That results in a NULL pointer dereference for the rare case where the underlying irq chip is lapic_chip which has no irq_set_affinity() callback. lapic_chip is occasionally used for the timer interrupt (irq 0). The fix is simple: Check the availability of the callback instead of calling it unconditionally. Fixes: 4857c91f "x86/ioapic: Force affinity setting in setup_ioapic_dest()" Signed-off-by:

commit 8a53554e upstream. When multiple GOP devices exists, but none of them implements ConOut, the code should just choose the first GOP (according to the comments). But currently 'fb_base' will refer to the last GOP, while other parameters to the first GOP, which will likely result in a garbled display. I can reliably reproduce this bug using my ASRock Z87M Extreme4 motherboard with CSM and integrated GPU disabled, and two PCIe video cards (NVidia GT640 and GTX980), booting from efi-stub (booting from grub works fine). On the primary display the ASRock logo remains and on the secondary screen it is garbled up completely. Signed-off-by:

commit 34198710 upstream. SX_TLV controls are intended for situations where the register behind the control has some non-zero value indicating the minimum gain and then gains increasing from there and eventually overflowing through zero. Currently every CODEC implementing these controls specifies the minimum as the non-zero value for the minimum and the maximum as the number of gain settings available. This means when the info callback subtracts the minimum value from the maximum value to calculate the number of gain levels available it is actually under reporting the available levels. This patch fixes this issue by adding a new snd_soc_info_volsw_sx callback that does not subtract the minimum value.

commit d18ca5b7 upstream. Add lock to prevent concurrent access for control message as control message function uses shared buffer. Without the lock there may be remote control polling which messes the buffer causing IO errors. Increase buffer size and add check for maximum supported message length.
