As TLB shootdown requests to other CPU cores are now using function call
interrupts, TLB shootdowns entry in /proc/interrupts is always shown as 0.
This behavior change was introduced by commit 52aec3308db8 ("x86/tlb:
replace INVALIDATE_TLB_VECTOR by CALL_FUNCTION_VECTOR").
This patch reverts TLB shootdowns entry in /proc/interrupts to count TLB

Here are two USB bugfixes for your 3.6-rc7 tree.
The OHCI fix has been reported a number of times and is a regression
from 3.5, and the patch that causes the regression was on the way to the
-stable trees before I was reminded (again) that this fix needed to get
to your tree soon.
The host controller bugfix was reported in older kernels as being pretty
easy to trigger, and has been tested by Red Hat and their customers.
Both have been in the usb-next branch in the -next tree for a while now,
I just cherry-picked them out to get to you in time for the 3.6 release.

The userspace part of UML uses the asm-offsets.h generator mechanism to
create definitions for UM_KERN_<LEVEL> that match the in-kernel
KERN_<LEVEL> constant definitions.
As of commit 04d2c8c83d0e3ac5f78aeede51babb3236200112 ("printk: convert
the format for KERN_<LEVEL> to a 2 byte pattern"), KERN_<LEVEL> is no
longer expanded to the literal '"<LEVEL>"', but to '"\001" "LEVEL"', i.e.
it contains two parts.
However, the combo of DEFINE_STR() in
arch/x86/um/shared/sysdep/kernel-offsets.h and sed-y in Kbuild doesn't
support string literals consisting of multiple parts. Hence for all
UM_KERN_<LEVEL> definitions, only the SOH character is retained in the actual
definition, while the remainder ends up in the comment. E.g. in
include/generated/asm-offsets.h we get
#define UM_KERN_INFO "\001" /* "6" KERN_INFO */
instead of
#define UM_KERN_INFO "\001" "6" /* KERN_INFO */
This causes spurious '^A' output in some kernel messages:
Calibrating delay loop... 4640.76 BogoMIPS (lpj=23203840)
pid_max: default: 32768 minimum: 301

^AChecking that host ptys support SIGIO on close...No, enabling workaround
^AUsing 2.6 host AIO
NET: Registered protocol family 16
bio: create slab <bio-0> at 0
Switching to clocksource itimer
To fix this:
- Move the mapping from UM_KERN_<LEVEL> to KERN_<LEVEL> from
arch/um/include/shared/common-offsets.h to
arch/um/include/shared/user.h, which is preincluded for all userspace
parts,
- Preinclude include/linux/kern_levels.h for all userspace parts, to
obtain the in-kernel KERN_<LEVEL> constant definitions. This doesn't
violate the kernel/userspace separation, as include/linux/kern_levels.h
is self-contained and doesn't expose any other kernel internals.
- Remove the now unused STR() and DEFINE_STR() macros.

There is no fundamental reason why we should switch SMEP and SMAP on
during early cpu initialization just to switch them off again. Now
with %eflags and %cr4 forced to be initialized to a clean state, we
only need the one-way enable. Also, make the functions inline to make
them (somewhat) harder to abuse.
This does mean that SMEP and SMAP do not get initialized anywhere near
as early. Even using early_param() instead of __setup() doesn't give
us control early enough to do this during the early cpu initialization
phase. This seems reasonable to me, because SMEP and SMAP should not
matter until we have userspace to protect ourselves from, but it does
potentially make it possible for a bug involving a "leak of
permissions to userspace" to get uncaught.

This patch (as1607) fixes a race that can occur if a USB host
controller is removed while a process is reading the
/sys/kernel/debug/usb/devices file.
The usb_device_read() routine uses the bus->root_hub pointer to
determine whether or not the root hub is registered. The is not a
valid test, because the pointer is set before the root hub gets
registered and remains set even after the root hub is unregistered and
deallocated. As a result, usb_device_read() or usb_device_dump() can
access freed memory, causing an oops.
The patch changes the test to use the hcd->rh_registered flag, which
does get set and cleared at the appropriate times. It also makes sure
to hold the usb_bus_list_lock mutex while setting the flag, so that
usb_device_read() will become aware of new root hubs as soon as they
are registered.

we only use that to tell copy_thread() done by syscall from that
done by kernel_thread(). However, it's easier to do simply by
checking PF_KTHREAD in thread flags.
Merge sys_clone() guts for 32bit and 64bit, while we are at it...

The newly added trace command requires an external audit library.
However it can cause a build error because it's not checked whether the
libaudit is installed on system:
CC builtin-trace.o
builtin-trace.c:7:22: fatal error: libaudit.h: No such file or directory
compilation terminated.
make: *** [builtin-trace.o] Error 1

Pull the RCU adaptive-idle feature from Paul E. McKenney:
"This series adds RCU APIs that allow non-idle tasks to
enter RCU idle mode and provides x86 code to make use of them, allowing
RCU to treat user-mode execution as an extended quiescent state when the
new RCU_USER_QS kernel configuration parameter is specified. Work is
in progress to port this to a few other architectures, but is not part
of this series."

The 'enough' function is written to work with 'near' arrays only
in that is implicitly assumes that the offset from one 'group' of
devices to the next is the same as the number of copies.
In reality it is the number of 'near' copies.
So change it to make this number explicit.
This bug makes it possible to run arrays without enough drives
present, which is dangerous.
It is appropriate for an -stable kernel, but will almost certainly
need to be modified for some of them.

Initially should look loosely like the venerable 'strace' tool, but
using the infrastructure in the perf tools to allow tracing extra
targets:
[acme@sandy linux]$ perf trace --hell
Error: unknown option `hell'
usage: perf trace <PID>
-p, --pid <pid> trace events on existing process id
--tid <tid> trace events on existing thread id
--all-cpus system-wide collection from all CPUs
--cpu <cpu> list of cpus to monitor
--no-inherit child tasks do not inherit counters
--mmap-pages <n> number of mmap data pages
--uid <user> user to profile
[acme@sandy linux]$
Those should have the same semantics as when using with 'perf record'.
It gets stuck sometimes, but hey, it works sometimes too!
In time it should support perf.data based workloads, i.e. it should have
a:
-o filename
Command line option that will produce a perf.data file that can then be
used with 'perf trace' or any of the other perf tools (script, report,
etc).
It will also eventually have the set of functionalities described in the
previous 'trace' prototype by Thomas Gleixner:
"Announcing a new utility: 'trace'"
http://lwn.net/Articles/415728/
Also planned is to have some of the features suggested in the comments
of that LWN article.
