We are taking a wrong regs snapshot when a trace event triggers.
Either we use get_irq_regs(), which gives us the interrupted
registers if we are in an interrupt, or we use task_pt_regs()
which gives us the state before we entered the kernel, assuming
we are lucky enough to be no kernel thread, in which case
task_pt_regs() returns the initial set of regs when the kernel
thread was started.What we want is different. We need a hot snapshot of the regs,
so that we can get the instruction pointer to record in the
sample, the frame pointer for the callchain, and some other
things.Let's use the new perf_fetch_caller_regs() for that.
Comparison with perf record -e lock: -R -a -f -g

| | | smp_apic_timer_interrupt
| | | apic_timer_interruptThe old case was producing unreliable callchains. Now having
right frame and instruction pointers, we have the trace we
want.Also syscalls and kprobe events already have the right regs,
let's use them instead of wasting a retrieval.v2: Follow the rename perf_save_regs() -> perf_fetch_caller_regs()

GCC 4.5 introduces behavior that forces the alignment of structures to
use the largest possible value. The default value is 32 bytes, so if
some structures are defined with a 4-byte alignment and others aren't
declared with an alignment constraint at all - it will align at 32-bytes.For things like the ftrace events, this results in a non-standard array.
When initializing the ftrace subsystem, we traverse the _ftrace_events
section and call the initialization callback for each event. When the
structures are misaligned, we could be treating another part of the
structure (or the zeroed out space between them) as a function pointer.This patch forces the alignment for all the ftrace_event_call structures
to 4 bytes.Without this patch, the kernel fails to boot very early when built with
gcc 4.5.It's trivial to check the alignment of the members of the array, so it
might be worthwhile to add something to the build system to do that
automatically. Unfortunately, that only covers this case. I've asked one
of the gcc developers about adding a warning when this condition is seen.Cc: stable@kernel.org

The functions used to implement the TRACE_EVENT macro show up in
function tracing. This is considered a distraction, and these should
not be displayed. For example:-0 [000] 57.202149: task_of -0 [000] 57.202149: ftrace_raw_event_sched_stat_wait -0 [000] 57.202150: ftrace_raw_event_id_sched_stat_template -0 [000] 57.202150: sched_stat_wait: comm=sshd pid=2735 delay=19207 [ns]
The "ftrace_raw_event_*" traces are just the utility functions used
by TRACE_EVENT tracepoints.Cc: Thomas Gleixner

Introduce ftrace_perf_buf_prepare() and ftrace_perf_buf_submit() to
gather the common code that operates on raw events sampling buffer.
This cleans up redundant code between regular trace events, syscall
events and kprobe events.Changelog v1->v2:
- Rename function name as per Masami and Frederic's suggestion
- Add __kprobes for ftrace_perf_buf_prepare() and make
ftrace_perf_buf_submit() inline as per Masami's suggestion
- Export ftrace_perf_buf_prepare since modules will use itSigned-off-by: Xiao Guangrong

This is part of a patch set that removes the show_format method
in the ftrace event macros.The print_fmt field is added to hold the string that shows

this field to enable us to remove the show_format field

Move the printk from each ftrace_raw_reg_event_foo() to

regfunc trace event callbacks to handle a same error report
that can be carried from the caller.See how much space this saves:

format '%lu' expects type 'long unsigned int', but argument 4 has type 'cputime_t'
....cputime_t on power is u64, which triggers the above warning.
Cast the cputime_t to unsigned long long and fix the print format
