Slow clocksources can have a way longer sleep time than 5 seconds and
even fast ones can easily cope with 600 seconds and still maintain
proper accuracy.

Group the hot path members of struct clocksource together so we have a
better cache line footprint. Make it cacheline aligned.

The original Makefile uses "uname -m" to determine ARCH.
This causes problem on x86 when compile perf tool on 32 bit
userspace with a 64 bit kernel.
bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages:
bench/../../../arch/x86/lib/memcpy_64.S:28: Error: bad register name `%rdi'
This is because "uname -m" returns x86_64 and memcpy_64.S is
included in 32 bit build.

ptrace_set_debugreg()
We make use of ptrace_get_breakpoints() / ptrace_put_breakpoints() to
protect ptrace_set_debugreg() even if CONFIG_HAVE_HW_BREAKPOINT if off.
However in this case, these APIs are not implemented.
To fix this, push the protection down inside the relevant ifdef.
Best would be to export the code inside
CONFIG_HAVE_HW_BREAKPOINT into a standalone function to cleanup
the ifdefury there and call the breakpoint ref API inside. But
as it is more invasive, this should be rather made in an -rc1.
Fixes this build error:
arch/powerpc/kernel/ptrace.c:1594: error: implicit declaration of function 'ptrace_get_breakpoints' make[2]: ***

While the tracer accesses ptrace breakpoints, the child task may
concurrently exit due to a SIGKILL and thus release its breakpoints
at the same time. We can then dereference some freed pointers.
To fix this, hold a reference on the child breakpoints before
manipulating them.

When a task is traced and is in a stopped state, the tracer
may execute a ptrace request to examine the tracee state and
get its task struct. Right after, the tracee can be killed
and thus its breakpoints released.
This can happen concurrently when the tracer is in the middle
of reading or modifying these breakpoints, leading to dereferencing
a freed pointer.
Hence, to prepare the fix, create a generic breakpoint reference
holding API. When a reference on the breakpoints of a task is
held, the breakpoints won't be released until the last reference
is dropped. After that, no more ptrace request on the task's
breakpoints can be serviced for the tracer.

errors, but the caller doesn't handle that situation properly. Fix the
thread to treat such a case as it would a malformed packet. Mark the
mid as being malformed and issue the callback.

There are a couple of places in this code where these values can wrap or
go negative, and that could potentially end up overflowing the buffer.
Ensure that that doesn't happen. Do all of the length calculation and
checks first, and only perform the memcpy after they pass.
Also, increase some stack variables to 32 bits to ensure that they don't
wrap without being detected.
Finally, change the error codes to be a bit more descriptive of any
problems detected. -EINVAL isn't very accurate.

It's possible that when we go to decode the string area in the
SESSION_SETUP response, that bytes_remaining will be 0. Decrementing it at
that point will mean that it can go "negative" and wrap. Check for a
bytes_remaining value of 0, and don't try to decode the string area if
that's the case.

The buffer length checks in this function depend on this value being a
signed data type, but 690c522fa converted it to an unsigned type.
Also, eliminate a problem with the null termination check in the same
function. cifs_strndup_from_ucs handles that situation correctly
already, and the existing check could potentially lead to a buffer
overrun since it increments bleft without checking to see whether it
falls off the end of the buffer.

This partially reverts commit e6e1e2593592a8f6f6380496655d8c6f67431266.
That commit changed the structure layout of the trace structure, which
in turn broke PowerTOP (1.9x generation) quite badly.
I appreciate not wanting to expose the variable in question, and
PowerTOP was not using it, so I've replaced the variable with just a
padding field - that way if in the future a new field is needed it can
just use this padding field.

[SCSI] put stricter guards on queue dead checks
is causing a potential NULL deref in scsi_run_queue() because the
q->queuedata may already be NULL by the time this function is called.
Since we shouldn't be running a queue that is being torn down, simply
add a NULL check in scsi_run_queue() to forestall this.

commit
ee621dd (net: atmel_macb Kconfig: remove long dependency line)
replaced a list of several explicit machines in the dependencies of MACB by
a single symbol that is selected by the respective machines. ee621dd missed
to let ARCH_AT91CAP9 select HAVE_NET_MACB though which is fixed here.

The logic in __get_user_pages() used to skip the stack guard page lookup
whenever the caller wasn't interested in seeing what the actual page
was. But Michel Lespinasse points out that there are cases where we
don't care about the physical page itself (so 'pages' may be NULL), but
do want to make sure a page is mapped into the virtual address space.
So using the existence of the "pages" array as an indication of whether
to look up the guard page or not isn't actually so great, and we really
should just use the FOLL_MLOCK bit. But because that bit was only set
for the VM_LOCKED case (and not all vma's necessarily have it, even for
mlock()), we couldn't do that originally.
Fix that by moving the VM_LOCKED check deeper into the call-chain, which
actually simplifies many things. Now mlock() gets simpler, and we can
also check for FOLL_MLOCK in __get_user_pages() and the code ends up
much more straightforward.

Hi us,
When i was compiling kernel, a warning happened to me.
The warning said like following.
drivers/staging/wlan-ng/cfg80211.c:709: warning: initialization from
incompatible pointer type.
See http://s1202.photobucket.com/albums/bb364/harrywei/?action=view¤t=patched2.png
for more details.
So i patch like following.

vhci_rx/vhci_tx threads are created once but stopped each
time the vdev is shut down. On subsequent attach wake_up_process()
oopses trying to access the stopped threads.
This patch does as before the kthread conversion which is to
create the threads each time a device is attached and stop the
threads when the device is shut down.

ft1000-pcmcia uses EXPORT_SYMBOL unnecessarily for sharing symbols
inside the same module. For some reason, this is causing section
conflicts on ia64 as well, even though neither are static.

This patch clears PORT_PLC if xhci_bus_resume() resumes a previous suspended
port, because if a port transition from U3 to U0 state, it will report a
port link state change, and software should clear the corresponding PLC bit.
It also uses hcd->speed to check if a port is a USB2 protocol port.
The patch fixes the issue that USB keyboard can not wakeup system from
hibernation.

This patch (as1460) fixes a regression in the usbip driver caused by
the new check for Transaction Translators in USB-2 hubs. The root hub
registered by vhci_hcd needs to have the has_tt flag set, because it
can connect to low- and full-speed devices as well as high-speed
devices.

In the case of missing platform_data we do not hold a spin_lock,
thus we should not call spin_unlock_irqrestore in the error path.
Also simplify the error handling by separating the successful path
from error path. I think this change improves readability.
