2015-03-05x86/intel/quark: Select COMMON_CLKAndy Shevchenko1-0/+1
The commit 8bbc2a135b63 ("x86/intel/quark: Add Intel Quark platform support") introduced a minimal support of Intel Quark SoC. That allows to use core parts of the SoC. However, the SPI, I2C, and GPIO drivers can't be selected by kernel configuration because they depend on COMMON_CLK. The patch adds a COMMON_CLK selection to the platfrom definition to allow user choose the drivers.

2015-03-05workqueue: fix hang involving racing cancel[_delayed]_work_sync()'s for ↵Tejun Heo2-5/+54
PREEMPT_NONE cancel[_delayed]_work_sync() are implemented using __cancel_work_timer() which grabs the PENDING bit using try_to_grab_pending() and then flushes the work item with PENDING set to prevent the on-going execution of the work item from requeueing itself. try_to_grab_pending() can always grab PENDING bit without blocking except when someone else is doing the above flushing during cancelation. In that case, try_to_grab_pending() returns -ENOENT. In this case, __cancel_work_timer() currently invokes flush_work(). The assumption is that the completion of the work item is what the other canceling task would be waiting for too and thus waiting for the same condition and retrying should allow forward progress without excessive busy looping Unfortunately, this doesn't work if preemption is disabled or the latter task has real time priority. Let's say task A just got woken up from flush_work() by the completion of the target work item. If, before task A starts executing, task B gets scheduled and invokes __cancel_work_timer() on the same work item, its try_to_grab_pending() will return -ENOENT as the work item is still being canceled by task A and flush_work() will also immediately return false as the work item is no longer executing. This puts task B in a busy loop possibly preventing task A from executing and clearing the canceling state on the work item leading to a hang. task A task B worker executing work __cancel_work_timer() try_to_grab_pending() set work CANCELING flush_work() block for work completion completion, wakes up A __cancel_work_timer() while (forever) { try_to_grab_pending() -ENOENT as work is being canceled flush_work() false as work is no longer executing } This patch removes the possible hang by updating __cancel_work_timer() to explicitly wait for clearing of CANCELING rather than invoking flush_work() after try_to_grab_pending() fails with -ENOENT.

2015-03-04seq_buf: Fix seq_buf_bprintf() truncationSteven Rostedt (Red Hat)1-1/+1
In seq_buf_bprintf(), bstr_printf() is used to copy the format into the buffer remaining in the seq_buf structure. The return of bstr_printf() is the amount of characters written to the buffer excluding the '\0', unless the line was truncated! If the line copied does not fit, it is truncated, and a '\0' is added to the end of the buffer. But in this case, '\0' is included in the length of the line written. To know if the buffer had overflowed, the return length will be the same or greater than the length of the buffer passed in. The check in seq_buf_bprintf() only checked if the length returned from bstr_printf() would fit in the buffer, as the seq_buf_bprintf() is only to be an all or nothing command. It either writes all the string into the seq_buf, or none of it. If the string is truncated, the pointers inside the seq_buf must be reset to what they were when the function was called. This is not the case. On overflow, it copies only part of the string. The fix is to change the overflow check to see if the length returned from bstr_printf() is less than the length remaining in the seq_buf buffer, and not if it is less than or equal to as it currently does. Then seq_buf_bprintf() will know if the write from bstr_printf() was truncated or not.

2015-03-04drm/msm/mdp5: Avoid flushing registers when CRTC is disabledStephane Viau1-7/+19
When a CRTC is disabled, no CTL is allocated to it (CRTC->ctl == NULL); in that case we should not try to FLUSH registers and do nothing instead. This can happen when we try to move a cursor but the CRTC's CTL (CONTROL) has not been allocated yet (inactive CRTC). It can also happens when we .atomic_check()/.atomic_flush() on a disabled CRTC. A CTL needs to be kept as long as the CRTC is alive. Releasing it after the last VBlank is safer than in .atomic_flush().

2015-03-05drm/mm: Support 4 GiB and larger rangesThierry Reding4-104/+110
The current implementation is limited by the number of addresses that fit into an unsigned long. This causes problems on 32-bit Tegra where unsigned long is 32-bit but drm_mm is used to manage an IOVA space of 4 GiB. Given the 32-bit limitation, the range is limited to 4 GiB - 1 (or 4 GiB - 4 KiB for page granularity). This commit changes the start and size of the range to be an unsigned 64-bit integer, thus allowing much larger ranges to be supported.

2015-03-04locks: fix fasync_struct memory leak in lease upgrade/downgrade handlingJeff Layton1-1/+2
Commit 8634b51f6ca2 (locks: convert lease handling to file_lock_context) introduced a regression in the handling of lease upgrade/downgrades. In the event that we already have a lease on a file and are going to either upgrade or downgrade it, we skip doing any list insertion or deletion and simply re-call lm_setup on the existing lease. As of commit 8634b51f6ca2 however, we end up calling lm_setup on the lease that was passed in, instead of on the existing lease. This causes us to leak the fasync_struct that was allocated in the event that there was not already an existing one (as it always appeared that there wasn't one).

2015-03-04clk: at91: implement suspend/resume for the PMC irqchipBoris BREZILLON2-1/+20
The irq line used by the PMC block is shared with several peripherals including the init timer which is registering its handler with IRQF_NO_SUSPEND. Implement the appropriate suspend/resume callback for the PMC irqchip, and inform irq core that PMC irq handler can be safely called while the system is suspended by setting IRQF_COND_SUSPEND.

The IRQ line used by the RTC device is usually shared with the system timer (PIT) on at91 platforms. Since timers are registering their handlers with IRQF_NO_SUSPEND, we should expect being called in suspended state, and properly wake the system up when this is the case. Set IRQF_COND_SUSPEND flag when registering the IRQ handler to inform irq core that it can safely be called while the system is suspended.

2015-03-04PM / wakeup: export pm_system_wakeup symbolBoris BREZILLON1-0/+1
Export pm_system_wakeup function to allow irq handlers to deal with system wakeup. This is needed for shared IRQ lines where one of the handler is registered with IRQF_NO_SUSPEND, while the other ones want to configure it as a wakeup source. In this specific case, irq core does not handle the wakeup process and leave the decision to each irq handler.

2015-03-04team: don't traverse port list using rcu in team_set_mac_addressJiri Pirko1-3/+3
Currently the list is traversed using rcu variant. That is not correct since dev_set_mac_address can be called which eventually calls rtmsg_ifinfo_build_skb and there, skb allocation can sleep. So fix this by remove the rcu usage here. Fixes: 3d249d4ca7 "net: introduce ethernet teaming device" Signed-off-by: Jiri Pirko <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2015-03-04net: fec: fix rcv is not last issue when do suspend/resume testFugang Duan1-1/+1
When do suspend/resume stress test, some log shows "rcv is not +last". The issue is that enet suspend will disable phy clock, phy link down, after resume back, enet MAC redo initial and ready to tx/rx packet, but phy still is not ready which is doing auto-negotiation. When phy link is not up, don't schdule napi soft irq. [Peter] It has fixed kernel panic after long time suspend/resume test with nfs rootfs.

This patch fixes the backward compatibility of the older driver with the newer firmware by making the binding unique so that the older driver won't recognize the non-supported interfaces. v2: Address comments from v1 * updated cover letter subject line with net: xgene * Documentation: formatted compatible string values as list v1: * Initial version ==================== Signed-off-by: David S.

2015-03-04net: ping: Return EAFNOSUPPORT when appropriate.Lorenzo Colitti2-4/+13
1. For an IPv4 ping socket, ping_check_bind_addr does not check the family of the socket address that's passed in. Instead, make it behave like inet_bind, which enforces either that the address family is AF_INET, or that the family is AF_UNSPEC and the address is 0.0.0.0. 2. For an IPv6 ping socket, ping_check_bind_addr returns EINVAL if the socket family is not AF_INET6. Return EAFNOSUPPORT instead, for consistency with inet6_bind. 3. Make ping_v4_sendmsg and ping_v6_sendmsg return EAFNOSUPPORT instead of EINVAL if an incorrect socket address structure is passed in. 4. Make IPv6 ping sockets be IPv6-only. The code does not support IPv4, and it cannot easily be made to support IPv4 because the protocol numbers for ICMP and ICMPv6 are different. This makes connect(::ffff:192.0.2.1) fail with EAFNOSUPPORT instead of making the socket unusable. Among other things, this fixes an oops that can be triggered by: int s = socket(AF_INET, SOCK_DGRAM, IPPROTO_ICMP); struct sockaddr_in6 sin6 = { .sin6_family = AF_INET6, .sin6_addr = in6addr_any, }; bind(s, (struct sockaddr *) &sin6, sizeof(sin6)); Change-Id: If06ca86d9f1e4593c0d6df174caca3487c57a241 Signed-off-by: Lorenzo Colitti <[email protected]> Signed-off-by: David S.
