It was __devinit, but it is also within a CONFIG_HOTPLUG guarded section
of code, so the __devinit does nothing but cause the following warning:
WARNING: vmlinux.o(.text+0x107a8): Section mismatch in reference from the function pcibios_finish_adding_to_bus() to the function .devinit.text:pcibios_claim_one_bus()
The function pcibios_finish_adding_to_bus() references
the function __devinit pcibios_claim_one_bus().
This is often because pcibios_finish_adding_to_bus lacks a __devinit
annotation or the annotation of pcibios_claim_one_bus is wrong.
It is also only (externally) used in arch/powerpc/kernel/of_platform.c
which cannot be built as a module so don't export it.

This patch updates the output from /proc/ppc64/lparcfg to display the

RTAS event scan has to run across all cpus. Right now we use a kernel
thread and set_cpus_allowed but in doing so we wake up the previous cpu
unnecessarily.
Some ftrace output shows this:
previous cpu (2):
[002] 7.022331: sched_switch: task swapper:0 [140] ==> rtasd:194 [120]
[002] 7.022338: sched_switch: task rtasd:194 [120] ==> migration/2:9 [0]
[002] 7.022344: sched_switch: task migration/2:9 [0] ==> swapper:0 [140]
next cpu (3):
[003] 7.022345: sched_switch: task swapper:0 [140] ==> rtasd:194 [120]
[003] 7.022371: sched_switch: task rtasd:194 [120] ==> swapper:0 [140]
We can use schedule_delayed_work_on and avoid the unnecessary wakeup.

Fix the fact that the IOAPIC version number in the x86_64 code path always
gets assigned to 0, instead of the correct value.
Before the patch: (from "dmesg" output):
ACPI: IOAPIC (id[0x08] address[0xfec00000] gsi_base[0])
IOAPIC[0]: apic_id 8, version 0, address 0xfec00000, GSI 0-23 <---
After the patch:
ACPI: IOAPIC (id[0x08] address[0xfec00000] gsi_base[0])
IOAPIC[0]: apic_id 8, version 32, address 0xfec00000, GSI 0-23 <---
History:
io_apic_get_version() was compiled out of the x86_64 code path in the commit
f2c2cca3acef8b253a36381d9b469ad4fb08563a:
Author: Andi Kleen <ak@suse.de>
Date: Tue Sep 26 10:52:37 2006 +0200
[PATCH] Remove APIC version/cpu capability mpparse checking/printing
ACPI went to great trouble to get the APIC version and CPU capabilities
of different CPUs before passing them to the mpparser. But all
that data was used was to print it out. Actually it even faked some data
based on the boot cpu, not on the actual CPU being booted.
Remove all this code because it's not needed.
Cc: len.brown@intel.com
At the time, the IOAPIC version number was deliberately not printed
in the x86_64 code path. However, after the x86 and x86_64 files were
merged, the net result is that the IOAPIC version is printed incorrectly
in the x86_64 code path.
The patch below provides a fix. I have tested it with acpi, and with
acpi=off, and did not see any problems.

Currently the output of trace_stat/workqueues is totally reversed:
# cat /debug/tracing/trace_stat/workqueues
...
1 17 17 210 37 `-blk_unplug_work+0x0/0x57
1 3779 3779 181 11 |-cfq_kick_queue+0x0/0x2f
1 3796 3796 kblockd/1:120
...
The correct output should be:
1 3796 3796 kblockd/1:120
1 3779 3779 181 11 |-cfq_kick_queue+0x0/0x2f
1 17 17 210 37 `-blk_unplug_work+0x0/0x57
It's caused by "tracing/stat: replace linked list by an rbtree for
sorting"
(53059c9b67a62a3dc8c80204d3da42b9267ea5a0).
dummpy_cmp() should return -1, so rb_node will always be inserted as
right-most node in the rbtree, thus we sort the output in ascending
order.

When the stat tracing framework prepares the entries from a tracer
to output them to the user, it starts by computing a linear sort
through a linked list to give the entries ordered by relevance
to the user.
This is quite ugly and causes a small latency when we begin to
read the file.
This patch changes that by turning the linked list into a red-black
tree. Athough the whole iteration using the start and next tracer
callbacks while opening the file remain the same, it is now much
more fast and scalable.
The rbtree guarantees O(log(n)) insertions whereas a linked
list with linear sorting brought us a O(n) despair. Now the
(visible) latency has disapeared.

The "trace" prefix in struct trace_stat_session type is annoying while

The blankline between each cpu's workqueue stat is not necessary, because
the cpu number is enough to part them by eye.
Old style also caused a blankline below headline, and made code complex

v3: zhaolei@cn.fujitsu.com: Change TRACE_EVENT definition to new format
introduced by Steven Rostedt: consolidate trace and trace_event headers
v2: kosaki@jp.fujitsu.com: print the function names instead of addr, and zap
the work addr
v1: zhaolei@cn.fujitsu.com: Make workqueue tracepoints use TRACE_EVENT macro
TRACE_EVENT is a more generic way to define tracepoints.
Doing so adds these new capabilities to the tracepoints:
- zero-copy and per-cpu splice() tracing
- binary tracing without printf overhead
- structured logging records exposed under /debug/tracing/events
- trace events embedded in function tracer output and other plugins
- user-defined, per tracepoint filter expressions
Then, this patch converts DEFINE_TRACE to TRACE_EVENT in workqueue related
tracepoints.

This tidies up the boot_cpu_data.flags probing on SH-4A. All of them have
a few things in common, which we can blindly set, rather than having each
subtype have to set the same flags. We can also make assumptions about
cache ways and the validity of PTEA, so this also kills off CPU_HAS_PTEA
