2015-01-17ARM: rockchip: disable jtag/sdmmc autoswitching on rk3288Heiko Stübner1-0/+27
rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux settings depending on the card state. This collides with a lot of assumptions. It only works when using the internal card-detect mechanism and breaks horribly when using either the normal card-detect via the slot-gpio function or via any other pin. Also there is of course no link between the mmc and jtag on the software-side, so the jtag clocks may very well be disabled when the card is ejected and the soc switches back to the jtag pinmux. Leaving the switching function enabled did result in mmc timeouts and rcu stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases, as we expect the devicetree to explicitly select either mmc or jtag pinmuxes anyway.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull ftrace fixes from Steven Rostedt: "This holds a few fixes to the ftrace infrastructure as well as the mixture of function graph tracing and kprobes. When jprobes and function graph tracing is enabled at the same time it will crash the system: # modprobe jprobe_example # echo function_graph > /sys/kernel/debug/tracing/current_tracer After the first fork (jprobe_example probes it), the system will crash. This is due to the way jprobes copies the stack frame and does not do a normal function return. This messes up with the function graph tracing accounting which hijacks the return address from the stack and replaces it with a hook function. It saves the return addresses in a separate stack to put back the correct return address when done. But because the jprobe functions do not do a normal return, their stack addresses are not put back until the function they probe is called, which means that the probed function will get the return address of the jprobe handler instead of its own. The simple fix here was to disable function graph tracing while the jprobe handler is being called. While debugging this I found two minor bugs with the function graph tracing. The first was about the function graph tracer sharing its function hash with the function tracer (they both get filtered by the same input). The changing of the set_ftrace_filter would not sync the function recording records after a change if the function tracer was disabled but the function graph tracer was enabled. This was due to the update only checking one of the ops instead of the shared ops to see if they were enabled and should perform the sync. This caused the ftrace accounting to break and a ftrace_bug() would be triggered, disabling ftrace until a reboot. The second was that the check to update records only checked one of the filter hashes. It needs to test both the "filter" and "notrace" hashes. The "filter" hash determines what functions to trace where as the "notrace" hash determines what functions not to trace (trace all but these). Both hashes need to be passed to the update code to find out what change is being done during the update. This also broke the ftrace record accounting and triggered a ftrace_bug(). This patch set also include two more fixes that were reported separately from the kprobe issue. One was that init_ftrace_syscalls() was called twice at boot up. This is not a major bug, but that call performed a rather large kmalloc (NR_syscalls * sizeof(*syscalls_metadata)). The second call made the first one a memory leak, and wastes memory. The other fix is a regression caused by an update in the v3.19 merge window. The moving to enable events early, moved the enabling before PID 1 was created. The syscall events require setting the TIF_SYSCALL_TRACEPOINT for all tasks. But for_each_process_thread() does not include the swapper task (PID 0), and ended up being a nop. A suggested fix was to add the init_task() to have its flag set, but I didn't really want to mess with PID 0 for this minor bug. Instead I disable and re-enable events again at early_initcall() where it use to be enabled. This also handles any other event that might have its own reg function that could break at early boot up" * tag 'trace-fixes-v3.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix enabling of syscall events on the command line tracing: Remove extra call to init_ftrace_syscalls() ftrace/jprobes/x86: Fix conflict between jprobes and function graph tracing ftrace: Check both notrace and filter for old hash ftrace: Fix updating of filters for shared global_ops filters

to be page aligned" This patch partially reverts commit 421520ba98290a73b35b7644e877a48f18e06004 (only the arm64 part). There is no guarantee that the boot-loader places other images like dtb in a different page than initrd start/end, especially when the kernel is built with 64KB pages. When this happens, such pages must not be freed. The free_reserved_area() already takes care of rounding up "start" and rounding down "end" to avoid freeing partially used pages.

Actually SLM calls intel_pebs_aliases_core2() which uses INST_RETIRED.ANY_P to count the number of cycles. It's a PEBS capable event. But inv and cmask must be set to count cycles. Considering SLM allows all events as PEBS with no flags, only INST_RETIRED.ANY_P, inv=1, cmask=16 needs to handled specially.

2015-01-16perf/rapl: Fix sysfs_show() initialization for RAPL PMUStephane Eranian1-12/+32
This patch fixes a problem with the initialization of the sysfs_show() routine for the RAPL PMU. The current code was wrongly relying on the EVENT_ATTR_STR() macro which uses the events_sysfs_show() function in the x86 PMU code. That function itself was relying on the x86_pmu data structure. Yet RAPL and the core PMU (x86_pmu) have nothing to do with each other. They should therefore not interact with each other. The x86_pmu structure is initialized at boot time based on the host CPU model. When the host CPU is not supported, the x86_pmu remains uninitialized and some of the callbacks it contains are NULL. The false dependency with x86_pmu could potentially cause crashes in case the x86_pmu is not initialized while the RAPL PMU is. This may, for instance, be the case in virtualized environments. This patch fixes the problem by using a private sysfs_show() routine for exporting the RAPL PMU events.

2015-01-15ftrace/jprobes/x86: Fix conflict between jprobes and function graph tracingSteven Rostedt (Red Hat)1-5/+15
If the function graph tracer traces a jprobe callback, the system will crash. This can easily be demonstrated by compiling the jprobe sample module that is in the kernel tree, loading it and running the function graph tracer. # modprobe jprobe_example.ko # echo function_graph > /sys/kernel/debug/tracing/current_tracer # ls The first two commands end up in a nice crash after the first fork. (do_fork has a jprobe attached to it, so "ls" just triggers that fork) The problem is caused by the jprobe_return() that all jprobe callbacks must end with. The way jprobes works is that the function a jprobe is attached to has a breakpoint placed at the start of it (or it uses ftrace if fentry is supported). The breakpoint handler (or ftrace callback) will copy the stack frame and change the ip address to return to the jprobe handler instead of the function. The jprobe handler must end with jprobe_return() which swaps the stack and does an int3 (breakpoint). This breakpoint handler will then put back the saved stack frame, simulate the instruction at the beginning of the function it added a breakpoint to, and then continue on. For function tracing to work, it hijakes the return address from the stack frame, and replaces it with a hook function that will trace the end of the call. This hook function will restore the return address of the function call. If the function tracer traces the jprobe handler, the hook function for that handler will not be called, and its saved return address will be used for the next function. This will result in a kernel crash. To solve this, pause function tracing before the jprobe handler is called and unpause it before it returns back to the function it probed. Some other updates: Used a variable "saved_sp" to hold kcb->jprobe_saved_sp. This makes the code look a bit cleaner and easier to understand (various tries to fix this bug required this change). Note, if fentry is being used, jprobes will change the ip address before the function graph tracer runs and it will not be able to trace the function that the jprobe is probing.

2015-01-14net: fec: fix MDIO bus assignement for dual fec SoC'sStefan Agner2-0/+30
On i.MX28, the MDIO bus is shared between the two FEC instances. The driver makes sure that the second FEC uses the MDIO bus of the first FEC. This is done conditionally if FEC_QUIRK_ENET_MAC is set. However, in newer designs, such as Vybrid or i.MX6SX, each FEC MAC has its own MDIO bus. Simply removing the quirk FEC_QUIRK_ENET_MAC is not an option since other logic, triggered by this quirk, is still needed. Furthermore, there are board designs which use the same MDIO bus for both PHY's even though the second bus would be available on the SoC side. Such layout are popular since it saves pins on SoC side. Due to the above quirk, those boards currently do work fine. The boards in the mainline tree with such a layout are: - Freescale Vybrid Tower with TWR-SER2 (vf610-twr.dts) - Freescale i.MX6 SoloX SDB Board (imx6sx-sdb.dts) This patch adds a new quirk FEC_QUIRK_SINGLE_MDIO for i.MX28, which makes sure that the MDIO bus of the first FEC is used in any case. However, the boards above do have a SoC with a MDIO bus for each FEC instance. But the PHY's are not connected in a 1:1 configuration. A proper device tree description is needed to allow the driver to figure out where to find its PHY. This patch fixes that shortcoming by adding a MDIO bus child node to the first FEC instance, along with the two PHY's on that bus, and making use of the phy-handle property to add a reference to the PHY's.

2015-01-13crypto: add missing crypto module aliasesMathias Krause2-1/+2
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 Beulich1-1/+21
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).

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.

2015-01-12powerpc: Work around gcc bug in current_thread_info()Michael Ellerman1-6/+7
In commit a3e5b356b3ab "powerpc: Don't use local named register variable in current_thread_info" Anton changed the way we did current_thread_info() to accommodate LLVM, and it was not meant to have any effect elsewhere. Unfortunately it has exposed a gcc bug, where r1 gets copied into another register and then gcc uses that register to restore the toc after a function call, even when that register is volatile and has been clobbered by the function call. We could revert Anton's patch, but it's not clear the original code is safe either, we may just have been lucky. The cleanest solution is to just use the existing CURRENT_THREAD_INFO() asm macro, and call it using inline asm. Segher points out we don't need volatile on the asm, if the result of the shift is unused it's fine for the compiler to elide it.

In the end I just created a separate path when tracepoints are enabled. The offset on the stack used for this store is not valid for ABIv2 and it causes strange issues. I noticed it because OPAL console input was broken.
