2014-05-09Revert "net: eth: cpsw: Correctly attach to GPIO bitbang MDIO driver"Johan Hovold
This reverts commit f8d56d8f892be43a2404356073e16401eb5a42e6 ("net: eth: cpsw: Correctly attach to GPIO bitbang MDIO driver"). Fix potential null-pointer dereference at probe if the mdio-gpio device has not been successfully probed yet. The offending commit is plain wrong for a number of reasons. First of all it accesses internal driver data of an unrelated device. Neither does it check that the data is non-null (which it is in case the device has not been probed yet). Furthermore, the decision on whether to treat any driver data according to the mdio-gpio driver's internals is made based on the node name. But the name is not compared against "mdio" which is the normal name for the node, but rather against "gpio" which the node does not have to be named (and shouldn't be according to the binding documentation). [ If this hack is to be kept out-of-tree it should at least be matching against the compatible property. ] Cc: Stefan Roese <sr@denx.de> Cc: stable <stable@vger.kernel.org> # v3.14 Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: David S.

2014-05-09drm/i915/vlv: reset VLV media force wake request registerJani Nikula
Media force wake get hangs the machine when the system is booted without displays attached. The assumption is that (at least some versions of) the firmware has skipped some initialization in that case. Empirical evidence suggests we need to reset the media force wake request register in addition to the render one to avoid hangs.

2014-05-09net: cdc_mbim: handle unaccelerated VLAN tagged framesBjørn Mork
This driver maps 802.1q VLANs to MBIM sessions. The mapping is based on a bogus assumption that all tagged frames will use the acceleration API because we enable NETIF_F_HW_VLAN_CTAG_TX. This fails for e.g. frames tagged in userspace using packet sockets. Such frames will erroneously be considered as untagged and silently dropped based on not being IP. Fix by falling back to looking into the ethernet header for a tag if no accelerated tag was found.

2014-05-09x86, vdso, time: Cast tv_nsec to u64 for proper shifting in update_vsyscall()Boris Ostrovsky
With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall() may lose upper bits or, worse, add them since compiler will do this: (u64)(tk->wall_to_monotonic.tv_nsec << tk->shift) instead of ((u64)tk->wall_to_monotonic.tv_nsec << tk->shift) So if, for example, tv_nsec is 0x800000 and shift is 8 we will end up with 0xffffffff80000000 instead of 0x80000000. And then we are stuck in the subsequent 'while' loop. We need an explicit cast.

2014-05-09x86: Fix typo preventing msr_set/clear_bit from having an effectAndres Freund
Due to a typo the msr accessor function introduced in 22085a66c2fab6cf9b9393c056a3600a6b4735de didn't have any lasting effects because they accidentally wrote the old value back. After c0a639ad0bc6b178b46996bd1f821a04643e2bde this at the very least this causes cpuid limits not to be lifted on some cpus leading to missing capabilities for those.

2014-05-09locks: only validate the lock vs. f_mode in F_SETLK codepathsJeff Layton
v2: replace missing break in switch statement (as pointed out by Dave Jones) commit bce7560d4946 (locks: consolidate checks for compatible filp->f_mode values in setlk handlers) introduced a regression in the F_GETLK handler. flock64_to_posix_lock is a shared codepath between F_GETLK and F_SETLK, but the f_mode checks should only be applicable to the F_SETLK codepaths according to POSIX. Instead of just reverting the patch, add a new function to do this checking and have the F_SETLK handlers call it.

2014-05-09mac80211: fix vif name tracingEliad Peller
If sdata doesn't have a valid dev (e.g. in case of monitor vif), the vif_name field was initialized with (a length of) some short string, but later was set to a different, potentially larger one. This resulted in out-of-bounds write, which usually appeared as garbage in the trace log. Simply trace sdata->name, as it should always have the correct name for both cases.

2014-05-09mac80211: allow VHT with peers not capable of 40MHzJohannes Berg
There are two (related) issues with this. One case, reported by Michal, is related to hostap: it unsets the 20/40 capability bit for stations that associate when it's in 20 MHz mode. The other case, reported by Eyal, is that some APs like Netgear R6300v2 and probably others based on the BCM4360 chipset can be configured for doing VHT at 20Mhz. In this case the beacon has a VHT IE but the HT cap indicates transmitter only support 20Mhz. In both of these cases, we currently avoid VHT and use only HT this means we can't use the highest rates (MCS8), so fixing this leads to throughput improvements.

2014-05-08sparc64: Fix huge TSB mapping on pre-UltraSPARC-III cpus.David S. Miller
Access to the TSB hash tables during TLB misses requires that there be an atomic 128-bit quad load available so that we fetch a matching TAG and DATA field at the same time. On cpus prior to UltraSPARC-III only virtual address based quad loads are available. UltraSPARC-III and later provide physical address based variants which are easier to use. When we only have virtual address based quad loads available this means that we have to lock the TSB into the TLB at a fixed virtual address on each cpu when it runs that process. We can't just access the PAGE_OFFSET based aliased mapping of these TSBs because we cannot take a recursive TLB miss inside of the TLB miss handler without risking running out of hardware trap levels (some trap combinations can be deep, such as those generated by register window spill and fill traps). Without huge pages it's working perfectly fine, but when the huge TSB got added another chunk of fixed virtual address space was not allocated for this second TSB mapping. So we were mapping both the 8K and 4MB TSBs to the same exact virtual address, causing multiple TLB matches which gives undefined behavior. Signed-off-by: David S. Miller <davem@davemloft.net>

2014-05-08tracepoint: Fix use of tracepoint funcs after rcu freeMathieu Desnoyers
Commit de7b2973903c "tracepoint: Use struct pointer instead of name hash for reg/unreg tracepoints" introduces a use after free by calling release_probes on the old struct tracepoint array before the newly allocated array is published with rcu_assign_pointer. There is a race window where tracepoints (RCU readers) can perform a "use-after-grace-period-after-free", which shows up as a GPF in stress-tests.

2014-05-08trace: module: Maintain a valid user countRomain Izard
The replacement of the 'count' variable by two variables 'incs' and 'decs' to resolve some race conditions during module unloading was done in parallel with some cleanup in the trace subsystem, and was integrated as a merge. Unfortunately, the formula for this replacement was wrong in the tracing code, and the refcount in the traces was not usable as a result. Use 'count = incs - decs' to compute the user count.

2014-05-08ACPI / processor: do not mark present at boot but not onlined CPU as onlinedIgor Mammedov
acpi_processor_add() assumes that present at boot CPUs are always onlined, it is not so if a CPU failed to become onlined. As result acpi_processor_add() will mark such CPU device as onlined in sysfs and following attempts to online/offline it using /sys/device/system/cpu/cpuX/online attribute will fail. Do not poke into device internals in acpi_processor_add() and touch "struct device { .offline }" attribute, since for CPUs onlined at boot it's set by: topology_init() -> arch_register_cpu() -> register_cpu() before ACPI device tree is parsed, and for hotplugged CPUs it's set when userspace onlines CPU via sysfs.

This reverts commit c42deffd5b53c9e583d83c7964854ede2f12410d. commit <mmc: rtsx: add support for pre_req and post_req> did use mutex_unlock() in tasklet, but mutex_unlock() can't be used in tasklet(atomic context). The driver needs to use mutex to avoid concurrency, so we can't use tasklet here, the patch need to be removed. The spinlock host->lock and pcr->lock may deadlock, one way to solve the deadlock is remove host->lock in sd_isr_done_transfer(), but if using workqueue the we can avoid using the spinlock and also avoid the problem.

2014-05-07x86-64, build: Fix stack protector Makefile breakage with 32-bit userlandGeorge Spelvin
If you are using a 64-bit kernel with 32-bit userland, then scripts/gcc-x86_64-has-stack-protector.sh invokes 32-bit gcc with -mcmodel=kernel, which produces: <stdin>:1:0: error: code model 'kernel' not supported in the 32 bit mode and trips the "broken compiler" test at arch/x86/Makefile:120. There are several places a fix is possible, but the following seems cleanest. (But it's minimal; it would also be possible to factor out a bunch of stuff from the two branches of the if.)
