All slow clk users are not properly claiming it (get + prepare + enable) before using it. If all users properly claiming this clock release it, the clock is disabled, but faulty users still depends on it, and the system hangs. This fix prevents the slow clock from being disabled, and should solve the hanging issue, but offending drivers should be patched to properly claim this clock.

2015-01-13crypto: add missing crypto module aliasesMathias Krause
Commit 5d26a105b5a7 ("crypto: prefix module autoloading with "crypto-"") changed the automatic module loading when requesting crypto algorithms to prefix all module requests with "crypto-". This requires all crypto modules to have a crypto specific module alias even if their file name would otherwise match the requested crypto algorithm. Even though commit 5d26a105b5a7 added those aliases for a vast amount of modules, it was missing a few. Add the required MODULE_ALIAS_CRYPTO annotations to those files to make them get loaded automatically, again. This fixes, e.g., requesting 'ecb(blowfish-generic)', which used to work with kernels v3.18 and below. Also change MODULE_ALIAS() lines to MODULE_ALIAS_CRYPTO(). The former won't work for crypto modules any more.

2015-01-13x86/xen: properly retrieve NMI reasonJan Beulich
Using the native code here can't work properly, as the hypervisor would normally have cleared the two reason bits by the time Dom0 gets to see the NMI (if passed to it at all). There's a shared info field for this, and there's an existing hook to use - just fit the two together. This is particularly relevant so that NMIs intended to be handled by APEI / GHES actually make it to the respective handler. Note that the hook can (and should) be used irrespective of whether being in Dom0, as accessing port 0x61 in a DomU would be even worse, while the shared info field would just hold zero all the time. Note further that hardware NMI handling for PVH doesn't currently work anyway due to missing code in the hypervisor (but it is expected to work the native rather than the PV way).

2015-01-13mm: mmu_gather: use tlb->end != 0 only for TLB invalidationWill Deacon
When batching up address ranges for TLB invalidation, we check tlb->end != 0 to indicate that some pages have actually been unmapped. As of commit f045bbb9fa1b ("mmu_gather: fix over-eager tlb_flush_mmu_free() calling"), we use the same check for freeing these pages in order to avoid a performance regression where we call free_pages_and_swap_cache even when no pages are actually queued up. Unfortunately, the range could have been reset (tlb->end = 0) by tlb_end_vma, which has been shown to cause memory leaks on arm64. Furthermore, investigation into these leaks revealed that the fullmm case on task exit no longer invalidates the TLB, by virtue of tlb->end == 0 (in 3.18, need_flush would have been set). This patch resolves the problem by reverting commit f045bbb9fa1b, using instead tlb->local.nr as the predicate for page freeing in tlb_flush_mmu_free and ensuring that tlb->end is initialised to a non-zero value in the fullmm case.

2015-01-12tipc: fix bug in broadcast retransmit codeJon Paul Maloy
In commit 58dc55f25631178ee74cd27185956a8f7dcb3e32 ("tipc: use generic SKB list APIs to manage link transmission queue") we replace all list traversal loops with the macros skb_queue_walk() or skb_queue_walk_safe(). While the previous loops were based on the assumption that the list was NULL-terminated, the standard macros stop when the iterator reaches the list head, which is non-NULL. In the function bclink_retransmit_pkt() this macro replacement has lead to a bug. When we receive a BCAST STATE_MSG we unconditionally call the function bclink_retransmit_pkt(), whether there really is anything to retransmit or not, assuming that the sequence number comparisons will lead to the correct behavior. However, if the transmission queue is empty, or if there are no eligible buffers in the transmission queue, we will by mistake pass the list head pointer to the function tipc_link_retransmit(). Since the list head is not a valid sk_buff, this leads to a crash. In this commit we fix this by only calling tipc_link_retransmit() if we actually found eligible buffers in the transmission queue.

2015-01-12ARM: 8255/1: perf: Prevent wraparound during overflowDaniel Thompson
If the overflow threshold for a counter is set above or near the 0xffffffff boundary then the kernel may lose track of the overflow causing only events that occur *after* the overflow to be recorded. Specifically the problem occurs when the value of the performance counter overtakes its original programmed value due to wrap around. Typical solutions to this problem are either to avoid programming in values likely to be overtaken or to treat the overflow bit as the 33rd bit of the counter. Its somewhat fiddly to refactor the code to correctly handle the 33rd bit during irqsave sections (context switches for example) so instead we take the simpler approach of avoiding values likely to be overtaken. We set the limit to half of max_period because this matches the limit imposed in __hw_perf_event_init(). This causes a doubling of the interrupt rate for large threshold values, however even with a very fast counter ticking at 4GHz the interrupt rate would only be ~1Hz.

2015-01-12ARM: 8266/1: Remove early stack deallocation from restore_user_regsDaniel Thompson
Currently restore_user_regs deallocates the SVC stack early in its execution and relies on no exception being taken between the deallocation and the registers being restored. The introduction of a default FIQ handler that also uses the SVC stack breaks this assumption and can result in corrupted register state. This patch works around the problem by removing the early stack deallocation and using r2 as a temporary instead. I have not found a way to do this without introducing an extra mov instruction to the macro.

2015-01-12ARM: at91: board-dt-sama5: add phy_fixup to override NAND_TreeWenyou Yang
Appearance: On some SAMA5D4EK boards, after power up, the Eth1 doesn't work. Reason: The PIOE2 pin is connected to the NAND_Tree# of KSZ8081, But it outputs LOW during the reset period, which cause the NAND_Tree# enabled. Add phy_fixup() to disable NAND_Tree by overriding the Operation Mode Strap Override register(i.e. Register 16h) to clear the NAND_Tree bit.

2015-01-12arm64: KVM: Fix HCR setting for 32bit guestsMarc Zyngier
Commit b856a59141b1 (arm/arm64: KVM: Reset the HCR on each vcpu when resetting the vcpu) moved the init of the HCR register to happen later in the init of a vcpu, but left out the fixup done in kvm_reset_vcpu when preparing for a 32bit guest. As a result, the 32bit guest is run as a 64bit guest, but the rest of the kernel still manages it as a 32bit. Fun follows. Moving the fixup to vcpu_reset_hcr solves the problem for good.

2015-01-12s390/uprobes: fix user space PER eventsJan Willeke
If uprobes are single stepped for example with gdb, the behavior should now be correct. Before this patch, when gdb was single stepping a uprobe, the result was a SIGILL. When PER is active for any storage alteration and a uprobe is hit, a storage alteration event is indicated. These over indications are filterd out by gdb, if no change has happened within the observed area.
