Merge tag 'trace-fixes-v3.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull ftrace bugfix from Steven Rostedt: "Takao Indoh reported that he was able to cause a ftrace bug while loading a module and enabling function tracing at the same time. He uncovered a race where the module when loaded will convert the calls to mcount into nops, and expects the module's text to be RW. But when function tracing is enabled, it will convert all kernel text (core and module) from RO to RW to convert the nops to calls to ftrace to record the function. After the convertion, it will convert all the text back from RW to RO. The issue is, it will also convert the module's text that is loading. If it converts it to RO before ftrace does its conversion, it will cause ftrace to fail and require a reboot to fix it again. This patch moves the ftrace module update that converts calls to mcount into nops to be done when the module state is still MODULE_STATE_UNFORMED. This will ignore the module when the text is being converted from RW back to RO" * tag 'trace-fixes-v3.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace/module: Hardcode ftrace_module_init() call into load_module()

BUG_ON() is a big hammer, and should be used _only_ if there is some major corruption that you cannot possibly recover from, making it imperative that the current process (and possibly the whole machine) be terminated with extreme prejudice. The trivial sanity check in the vmacache code is *not* such a fatal error. Recovering from it is absolutely trivial, and using BUG_ON() just makes it harder to debug for no actual advantage. To make matters worse, the placement of the BUG_ON() (only if the range check matched) actually makes it harder to hit the sanity check to begin with, so _if_ there is a bug (and we just got a report from Srivatsa Bhat that this can indeed trigger), it is harder to debug not just because the machine is possibly dead, but because we don't have better coverage. BUG_ON() must *die*. Maybe we should add a checkpatch warning for it, because it is simply just about the worst thing you can ever do if you hit some "this cannot happen" situation. Reported-by:

A race exists between module loading and enabling of function tracer. CPU 1 CPU 2 ----- ----- load_module() module->state = MODULE_STATE_COMING register_ftrace_function() mutex_lock(&ftrace_lock); ftrace_startup() update_ftrace_function(); ftrace_arch_code_modify_prepare() set_all_module_text_rw(); <enables-ftrace> ftrace_arch_code_modify_post_process() set_all_module_text_ro(); [ here all module text is set to RO, including the module that is loading!! ] blocking_notifier_call_chain(MODULE_STATE_COMING); ftrace_init_module() [ tries to modify code, but it's RO, and fails! ftrace_bug() is called] When this race happens, ftrace_bug() will produces a nasty warning and all of the function tracing features will be disabled until reboot. The simple solution is to treate module load the same way the core kernel is treated at boot. To hardcode the ftrace function modification of converting calls to mcount into nops. This is done in init/main.c there's no reason it could not be done in load_module(). This gives a better control of the changes and doesn't tie the state of the module to its notifiers as much. Ftrace is special, it needs to be treated as such. The reason this would work, is that the ftrace_module_init() would be called while the module is in MODULE_STATE_UNFORMED, which is ignored by the set_all_module_text_ro() call.

This patch fixes this section mismatch: WARNING: vmlinux.o(.text+0x1efc4): Section mismatch in reference from the function apm821xx_pciex_init_port_hw() to the function .init.text:ppc4xx_pciex_wait_on_sdr.isra.9() The function apm821xx_pciex_init_port_hw() references the function __init ppc4xx_pciex_wait_on_sdr.isra.9(). This is often because apm821xx_pciex_init_port_hw lacks a __init annotation or the annotation of ppc4xx_pciex_wait_on_sdr.isra.9 is wrong. apm821xx_pciex_init_port_hw is only referenced by a struct in __initdata, so it should be safe to add __init to apm821xx_pciex_init_port_hw.

The secondary threads in the core are kept offline before launching guests in kvm on powerpc: "371fefd6:KVM: PPC: Allow book3s_hv guests to use SMT processor modes." Hence their runlatch bits are cleared. When the secondary threads are called in to start a guest, their runlatch bits need to be set to indicate that they are busy. The primary thread has its runlatch bit set though, but there is no harm in setting this bit once again. Hence set the runlatch bit for all threads before they start guest. Signed-off-by:

Up until now we have been setting the runlatch bits for a busy CPU and clearing it when a CPU enters idle state. The runlatch bit has thus been consistent with the utilization of a CPU as long as the CPU is online. However when a CPU is hotplugged out the runlatch bit is not cleared. It needs to be cleared to indicate an unused CPU. Hence this patch has the runlatch bit cleared for an offline CPU just before entering an idle state and sets it immediately after it exits the idle state. Signed-off-by:

While testing memory hot-remove, I found following dead lock: Process #1141 is drmgr, trying to remove some memory, i.e. memory499. It holds the memory_hotplug_mutex, and blocks when trying to remove file "online" under dir memory499, in kernfs_drain(), at wait_event(root->deactivate_waitq, atomic_read(&kn->active) == KN_DEACTIVATED_BIAS); Process #1120 is trying to online memory499 by echo 1 > memory499/online In .kernfs_fop_write, it uses kernfs_get_active() to increase &kn->active, thus blocking process #1141.

We have two definitions of COMMAND_LINE_SIZE, one for the kernel and one for the boot wrapper. I assume this is so the boot wrapper can be self sufficient and not rely on kernel headers. Having two defines with the same name is confusing, I just updated the wrong one when trying to bump it. Make the boot wrapper define unique by calling it BOOT_COMMAND_LINE_SIZE. Signed-off-by:
