Instead of just sorting the ip's of the functions per ftrace page,
sort the entire list before adding them to the ftrace pages.
This will allow the bsearch algorithm to be sped up as it can
also sort by pages, not just records within a page.

According to Documentation/trace/ftrace.txt:
tracing_cpumask:
This is a mask that lets the user only trace
on specified CPUS. The format is a hex string
representing the CPUS.
The tracing_cpumask currently doesn't affect the tracing state of
per-CPU ring buffers.
This patch enables/disables CPU recording as its corresponding bit in
tracing_cpumask is set/unset.

When the ring buffer does its consistency test on itself, it
removes the head page, runs the tests, and then adds it back
to what the "head_page" pointer was. But because the head_page
pointer may lack behind the real head page (held by the link
list pointer). The reset may be incorrect.
Instead, if the head_page exists (it does not on first allocation)
reset it back to the real head page before running the consistency
tests. Then it will be put back to its original location after
the tests are complete.

There use to be ring buffer integrity checks after updating the
size of the ring buffer. But now that the ring buffer can modify
the size while the system is running, the integrity checks were
removed, as they require the ring buffer to be disabed to perform
the check.
Move the integrity check to the reading of the ring buffer via the
iterator reads (the "trace" file). As reading via an iterator requires
disabling the ring buffer, it is a perfect place to have it.
If the ring buffer happens to be disabled when updating the size,
we still perform the integrity check.

There is no need to save any active fpu state to the task structure
memory if the task is dead. Just drop the state instead.
For example, this saved some 1770 xsave's during the system boot

Code paths like fork(), exit() and signal handling flush the fpu
state explicitly to the structures in memory.
BUG_ON() in __sanitize_i387_state() is checking that the fpu state
is not live any more. But for preempt kernels, task can be scheduled
out and in at any place and the preload_fpu logic during context switch
can make the fpu registers live again.
For example, consider a 64-bit Task which uses fpu frequently and as such
you will find its fpu_counter mostly non-zero. During its time slice, kernel
used fpu by doing kernel_fpu_begin/kernel_fpu_end(). After this, in the same
scheduling slice, task-A got a signal to handle. Then during the signal
setup path we got preempted when we are just before the sanitize_i387_state()
in arch/x86/kernel/xsave.c:save_i387_xstate(). And when we come back we
will have the fpu registers live that can hit the bug_on.
Similarly during core dump, other threads can context-switch in and out
(because of spurious wakeups while waiting for the coredump to finish in
kernel/exit.c:exit_mm()) and the main thread dumping core can run into this
bug when it finds some other thread with its fpu registers live on some other cpu.
So remove the paranoid check for now, even though it caught a bug in the
multi-threaded core dump case (fixed in the previous patch).

Nalluru reported hitting the BUG_ON(__thread_has_fpu(tsk)) in
arch/x86/kernel/xsave.c:__sanitize_i387_state() during the coredump
of a multi-threaded application.
A look at the exit seqeuence shows that other threads can still be on the
runqueue potentially at the below shown exit_mm() code snippet:
if (atomic_dec_and_test(&core_state->nr_threads))
complete(&core_state->startup);
===> other threads can still be active here, but we notify the thread
===> dumping core to wakeup from the coredump_wait() after the last thread
===> joins this point. Core dumping thread will continue dumping
===> all the threads state to the core file.
for (;;) {
set_task_state(tsk, TASK_UNINTERRUPTIBLE);
if (!self.task) /* see coredump_finish() */
break;
schedule();
}
As some of those threads are on the runqueue and didn't call schedule() yet,
their fpu state is still active in the live registers and the thread
proceeding with the coredump will hit the above mentioned BUG_ON while
trying to dump other threads fpustate to the coredump file.
BUG_ON() in arch/x86/kernel/xsave.c:__sanitize_i387_state() is
in the code paths for processors supporting xsaveopt. With or without
xsaveopt, multi-threaded coredump is broken and maynot contain
the correct fpustate at the time of exit.
In coredump_wait(), wait for all the threads to be come inactive, so
that we are sure all the extended register state is flushed to
the memory, so that it can be reliably copied to the core file.

Currently IA64 has a assembler implementation of sigrtprocmask.
Having a single architecture implement this in assembler language
is a serious maintenance problem that inhibits further evolution of the
signal subsystem. Everyone who wants to do deep changes to signals
would need to learn that assembler language.
Whatever performance improvements IA64 gets from this it cannot be worth
the price in maintainability.
We have some locking problems in signal that need to be fixed,
but this roadblock needs to be removed first.
So just disable the special assembler IA64 implementation and fall back to a
normal syscall there.

This patch adds the capability to remove pages from a ring buffer
without destroying any existing data in it.
This is done by removing the pages after the tail page. This makes sure
that first all the empty pages in the ring buffer are removed. If the
head page is one in the list of pages to be removed, then the page after
the removed ones is made the head page. This removes the oldest data
from the ring buffer and keeps the latest data around to be read.
To do this in a non-racey manner, tracing is stopped for a very short
time while the pages to be removed are identified and unlinked from the
ring buffer. The pages are freed after the tracing is restarted to
minimize the time needed to stop tracing.
The context in which the pages from the per-cpu ring buffer are removed
runs on the respective CPU. This minimizes the events not traced to only
NMI trace contexts.

On gcc 4.5 the function tracing_mark_write() would give a warning
of page2 being uninitialized. This is due to a bug in gcc because
the logic prevents page2 from being used uninitialized, and
gcc 4.6+ does not complain (correctly).
Instead of adding a "unitialized" around page2, which could show
a bug later on, I combined page1 and page2 into an array map_pages[].
This binds the two and the two are modified according to nr_pages
(what gcc 4.5 seems to ignore). This no longer gives a warning with
gcc 4.5 nor with gcc 4.6.

Pull networking tree from David Miller:
1) ptp_pch driver build broke during this merge window due to missing
slab.h header, fix from Geery Uytterhoeven.
2) If ipset passes in a bogus hash table size we crash because the size
is not validated properly. Compounding this, gcc-4.7 can miscompile
ipset such that even when the user specifies legitimate parameters
the tool passes in an out-of-range size to the kernel.
Fix from Jozsef Kadlecsik.
3) Users have reported that the netdev watchdog can trigger with pch_gbe
devices, and it turns out this is happening because of races in the
TX path of the driver leading to the transmitter hanging. Fix from
Eric Dumazet, reported and tested by Andy Cress.
4) Novatel USB551L devices match the generic class entries for the cdc
ethernet USB driver, but they don't work because they have generic
descriptors and thus need FLAG_WWAN to function properly.
Add the necessary ID table entry to fix this, from Dan Williams.
5) A recursive locking fix in the USBNET driver added a new problem, in
that packet list traversal is now racy and we can thus access
unlinked SKBs and crash.
Avoid this situation by adding some extra state tracking, from Ming
Lei.
6) The rtlwifi conversion to asynchronous firmware loading is racy, fix

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187
7) Fix regressions with bluetooth keyboards by notifying userland
properly when the security level changes, from Gustavo Padovan.
8) Bluetooth needs to make sure device connected events are emitted
before other kinds of events, otherwise userspace will think there is
no baseband link yet and therefore abort the sockets associated with
that connection.

This passes siginfo and mcontext to tilegx32 signal handlers that
don't have SA_SIGINFO set just as we have been doing for tilegx64.

First, we were at risk of handling thread-info flags, in particular
do_signal(), when returning from kernel space. This could happen
after a failed kernel_execve(), or when forking a kernel thread.
The fix is to test in do_work_pending() for user_mode() and return
immediately if so; we already had this test for one of the flags,
so I just hoisted it to the top of the function.
Second, if a ptraced process updated the callee-saved registers
in the ptregs struct and then processed another thread-info flag, we
would overwrite the modifications with the original callee-saved
registers. To fix this, we add a register to note if we've already
saved the registers once, and skip doing it on additional passes
through the loop. To avoid a performance hit from the couple of
extra instructions involved, I modified the GET_THREAD_INFO() macro
to be guaranteed to be one instruction, then bundled it with adjacent
instructions, yielding an overall net savings.

This patch unifies speed setting for both supported tablets. Functionality
of "wacom_poke" (used only by Graphire) is now in "wacom_set_features".
Reporting speed for both tablets can be changed by somethinkg like:
echo 1 > /sys/class/bluetooth/hci0/hci0:1/{device No}/speed
Accepted values:
0 - low speed,
1 - high speed.
The way of changing reporting speed is the same for Graphire and Intuos4 WL.

Add option to change reporting speed for Intuos4 WL. The option is only
internal to the module, but it will be extended to allow control over sysfs,
as it is already implemented for Graphire.

That check is valid only for Wacom Graphire, as the device raports always
start with 0x03. Intuos4 WL high-speed raports begin with 0x04, so
the check would be filtering out valid reports.

The hash size must fit both into u32 (jhash) and the max value of
size_t. The missing checking could lead to kernel crash, bug reported
by Seblu.

The qeth layer3 driver is notified about IP address changes.
Changes concerning qeth driven network interfaces have to be
forwarded to the OSA-card. This includes IP addresses of VLAN
interfaces with a qeth device as base device. Function
qeth_l3_verify_vlan_dev() determines if the net_device of the
IP event belongs to a vlan device belonging to a qeth device
as real device. This function is broken starting with commit
7ff0bcf676f7ed224ce21b58c7858c8e527068b2 , which means IP
addresses of VLAN devices are no longer set at the base qeth
device. The patch repairs function qeth_l3_verify_vlan_dev().

Commit 1abd2296b4a1ee7b6a883541c3ede52042a09521 starts removing
token ring from qeth_l3. This patch removes the rest of token
ring related code from the driver.
