Every tracing file must have its own TRACE_SYSTEM defined. The brcmsmac tracepoint header broke this and added in the middle of the file: #undef TRACE_SYSTEM #define TRACE_SYSTEM brcmsmac #undef TRACE_SYSTEM #define TRACE_SYSTEM brcmsmac_tx #undef TRACE_SYSTEM #define TRACE_SYSTEM brcmsmac_msg Unfortunately, this broke new code in the ftrace infrastructure. Moving each of these TRACE_SYSTEMs into their own trace file with just one TRACE_SYSTEM per file fixes the issue.

Dynamically allocated trampolines call ftrace_ops_get_func to get the function which they should call. For dynamic fops (FTRACE_OPS_FL_DYNAMIC flag is set) ftrace_ops_list_func is always returned. This is reasonable for static trampolines but goes against the main advantage of dynamic ones, that is avoidance of going through the list of all registered callbacks for functions that are only being traced by a single callback. We can fix it by returning ops->func (or recursion safe version) from ftrace_ops_get_func whenever it is possible for dynamic trampolines. Note that dynamic trampolines are not allowed for dynamic fops if CONFIG_PREEMPT=y.

A clean up of the recursive protection code changed val = this_cpu_read(current_context); val--; val &= this_cpu_read(current_context); to val = this_cpu_read(current_context); val &= val & (val - 1); Which has a duplicate use of '&' as the above is the same as val = val & (val - 1); Actually, it would be best to remove that line altogether and just add it to where it is used. And Christoph even mentioned that it can be further compacted to just a single line: __this_cpu_and(current_context, __this_cpu_read(current_context) - 1); Link: http://lkml.kernel.org/alpine.DEB.2.11.1503271423580.23114@gentwo.orgSuggested-by: Christoph Lameter <cl@linux.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

The commit that added a check for this to checkpatch says: "Using weak declarations can have unintended link defects. The __weak on the declaration causes non-weak definitions to become weak." In this case, when a PowerPC kernel is built with CONFIG_KPROBE_EVENT but not CONFIG_UPROBE_EVENT, it generates the following warning: WARNING: 1 bad relocations c0000000014f2190 R_PPC64_ADDR64 uprobes_fetch_type_table This is fixed by passing the fetch_table arrays to traceprobe_parse_probe_arg() which also means that they can never be NULL.

TRACE_EVENT_FL_USE_CALL_FILTER flag in ftrace:functon event can be removed. This flag was first introduced in commit f306cc82 ("tracing: Update event filters for multibuffer"). Now, the only place uses this flag is ftrace:function, but the filter of ftrace:function has a different code path with events/syscalls and events/tracepoints. It uses ftrace_filter_write() and perf's ftrace_profile_set_filter() to set the filter, the functionality of file 'tracing/events/ftrace/function/filter' is bypassed in function init_pred(), in which case, neither call->filter nor file->filter is used. So we can safely remove TRACE_EVENT_FL_USE_CALL_FILTER flag from ftrace:function events.

It has come to my attention that this_cpu_read/write are horrible on architectures other than x86. Worse yet, they actually disable preemption or interrupts! This caused some unexpected tracing results on ARM. 101.356868: preempt_count_add <-ring_buffer_lock_reserve 101.356870: preempt_count_sub <-ring_buffer_lock_reserve The ring_buffer_lock_reserve has recursion protection that requires accessing a per cpu variable. But since preempt_disable() is traced, it too got traced while accessing the variable that is suppose to prevent recursion like this. The generic version of this_cpu_read() and write() are: #define this_cpu_generic_read(pcp) \ ({ typeof(pcp) ret__; \ preempt_disable(); \ ret__ = *this_cpu_ptr(&(pcp)); \ preempt_enable(); \ ret__; \ }) #define this_cpu_generic_to_op(pcp, val, op) \ do { \ unsigned long flags; \ raw_local_irq_save(flags); \ *__this_cpu_ptr(&(pcp)) op val; \ raw_local_irq_restore(flags); \ } while (0) Which is unacceptable for locations that know they are within preempt disabled or interrupt disabled locations. Paul McKenney stated that __this_cpu_() versions produce much better code on other architectures than this_cpu_() does, if we know that the call is done in a preempt disabled location. I also changed the recursive_unlock() to use two local variables instead of accessing the per_cpu variable twice.

Pull clock framework fixes from Michael Turquette: "The clk fixes for 4.0-rc4 comprise three themes. First are the usual driver fixes for new regressions since v3.19. Second are fixes to the common clock divider type caused by recent changes to how we round clock rates. This affects many clock drivers that use this common code. Finally there are fixes for drivers that improperly compared struct clk pointers (drivers must not deref these pointers). While some of these drivers have done this for a long time, this did not cause a problem until we started generating unique struct clk pointers for every consumer. A new function, clk_is_match was introduced to get these drivers working again and they are fixed up to no longer deref the pointers themselves" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: ASoC: kirkwood: fix struct clk pointer comparing ASoC: fsl_spdif: fix struct clk pointer comparing ARM: imx: fix struct clk pointer comparing clk: introduce clk_is_match clk: don't export static symbol clk: divider: fix calculation of initial best divider when rounding to closest clk: divider: fix selection of divider when rounding to closest clk: divider: fix calculation of maximal parent rate for a given divider clk: divider: return real rate instead of divider value clk: qcom: fix platform_no_drv_owner.cocci warnings clk: qcom: fix platform_no_drv_owner.cocci warnings clk: qcom: Add PLL4 vote clock clk: qcom: lcc-msm8960: Fix PLL rate detection clk: qcom: Fix slimbus n and m val offsets clk: ti: Fix FAPLL parent enable bit handling

Catalin Marinas authored
The ARM architecture allows the caching of intermediate page table levels and page table freeing requires a sequence like: pmd_clear() TLB invalidation pte page freeing With commit 5e5f6dc1 (arm64: mm: enable HAVE_RCU_TABLE_FREE logic), the page table freeing batching was moved from tlb_remove_page() to tlb_remove_table(). The former takes care of TLB invalidation as this is also shared with pte clearing and page cache page freeing. The latter, however, does not invalidate the TLBs for intermediate page table levels as it probably relies on the architecture code to do it if required. When the mm->mm_users < 2, tlb_remove_table() does not do any batching and page table pages are freed before tlb_finish_mmu() which performs the actual TLB invalidation. This patch introduces __tlb_flush_pgtable() for arm64 and calls it from the {pte,pmd,pud}_free_tlb() directly without relying on deferred page table freeing.

sparc:allmodconfig fails to build with: drivers/built-in.o: In function `platform_bus_init': (.init.text+0x3684): undefined reference to `of_platform_register_reconfig_notifier' of_platform_register_reconfig_notifier is only declared if both OF_ADDRESS and OF_DYNAMIC are configured. Yet, the include file only declares a dummy function if OF_DYNAMIC is not configured. The sparc architecture does not configure OF_ADDRESS, but does configure OF_DYNAMIC, causing above error.

The current HDA generic parser initializes / modifies the amp values always in stereo, but this seems causing the problem on ALC3229 codec that has a few mono channel widgets: namely, these mono widgets react to actions for both channels equally. In the driver code, we do care the mono channel and create a control only for the left channel (as defined in HD-audio spec) for such a node. When the control is updated, only the left channel value is changed. However, in the resume, the right channel value is also restored from the initial value we took as stereo, and this overwrites the left channel value. This ends up being the silent output as the right channel has been never touched and remains muted. This patch covers the places where unconditional stereo amp accesses are done and converts to the conditional accesses.
