On the syscall tracing path, we call out to secure_computing() to allow
seccomp to check the syscall number being attempted. As part of this, a
SIGTRAP may be sent to the tracer and the syscall could be re-written by
a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall
is ignored by the current code unless TIF_SYSCALL_TRACE is also set on
the current thread.
This patch slightly reworks the enter path of the syscall tracing code
so that we always reload the syscall number from
current_thread_info()->syscall after the potential ptrace traps.

nommu targets never actually set a limit on memblock though which
means memblock_get_current_limit will just return the default

When a PL310 cache is used on a system that provides hardware
coherency, the outer cache sync operation is useless, and can be
skipped. Moreover, on some systems, it is harmful as it causes
deadlocks between the Marvell coherency mechanism, the Marvell PCIe
controller and the Cortex-A9.
To avoid this, this commit introduces a new Device Tree property
'arm,io-coherent' for the L2 cache controller node, valid only for the
PL310 cache. It identifies the usage of the PL310 cache in an I/O
coherent configuration. Internally, it makes the driver disable the
outer cache sync operation.
Note that technically speaking, a fully coherent system wouldn't
require any of the other .outer_cache operations. However, in
practice, when booting secondary CPUs, these are not yet coherent, and
therefore a set of cache maintenance operations are necessary at this
point. This explains why we keep the other .outer_cache operations and
only ->sync is disabled.
While in theory any write to a PL310 register could cause the
deadlock, in practice, disabling ->sync is sufficient to workaround
the deadlock, since the other cache maintenance operations are only
used in very specific situations.
Contrary to previous versions of this patch, this new version does not
simply NULL-ify the ->sync member, because the l2c_init_data
structures are now 'const' and therefore cannot be modified, which is
a good thing. Therefore, this patch introduces a separate
l2c_init_data instance, called of_l2c310_coherent_data.

On uniprocessor preemptible kernel, target core deadlocks on unload. The
following events happen:
* iscsit_del_np is called
* it calls send_sig(SIGINT, np->np_thread, 1);
* the scheduler switches to the np_thread
* the np_thread is woken up, it sees that kthread_should_stop() returns
false, so it doesn't terminate
* the np_thread clears signals with flush_signals(current); and goes back
to sleep in iscsit_accept_np
* the scheduler switches back to iscsit_del_np
* iscsit_del_np calls kthread_stop(np->np_thread);
* the np_thread is waiting in iscsit_accept_np and it doesn't respond to
kthread_stop
The deadlock could be resolved if the administrator sends SIGINT signal to
the np_thread with killall -INT iscsi_np
The reproducible deadlock was introduced in commit
db6077fd0b, but the thread-stopping code was
racy even before.
This patch fixes the problem. Using kthread_should_stop to stop the
np_thread is unreliable, so we test np_thread_state instead. If
np_thread_state equals ISCSI_NP_THREAD_SHUTDOWN, the thread exits.

Pull x86 fixes from Peter Anvin:
"A pile of fixes related to the VDSO, EFI and 32-bit badsys handling.
It turns out that removing the section headers from the VDSO breaks
gdb, so this puts back most of them. A very simple typo broke
rt_sigreturn on some versions of glibc, with obviously disastrous
results. The rest is pretty much fixes for the corresponding fallout.
The EFI fixes fixes an arithmetic overflow on 32-bit systems and
quiets some build warnings.
Finally, when invoking an invalid system call number on x86-32, we
bypass a bunch of handling, which can make the audit code oops"

Here includes a few patchset for fixing mostly HD-audio issues in
addition to a patch assuring the compress API bytes alignment and a
fix for the die-hard existing race condition at USB-audio
disconnection. The volume looks big in Realtek HD-audio code, but
it's just a translation of the fixup tables, and the actual changes
are rather trivial.

This patch changes iscsit_check_dataout_hdr() to dump the incoming
Data-Out payload when the received ITT is not associated with a
WRITE, instead of calling iscsit_reject_cmd() for the non WRITE
ITT descriptor.
This addresses a bug where an initiator sending an Data-Out for
an ITT associated with a READ would end up generating a reject
for the READ, eventually resulting in list corruption.
