5ff6197f82 Blackfin: strncpy: fix handling of zero lengths
The jump to 4f will cause the NUL padding loop to run at least one time,
so if string length is zero just jump to the end.  Otherwise we wrongly
write one NUL byte when size==0.

c320afe965 Blackfin: debug-mmrs: include RSI_PID[4567] MMRs
The documentation is a little iffy as to whether these are actual MMRs,
but reading them on the hardware works, and the previous version of this
logic (the SDH) had PID[4567].  So add it for RSI too.

fcb243918f Blackfin: bf51x: fix up RSI_PID# MMR defines
Looks like the copying of MMR defines from the SDH block missed updating

61aa818f7b Blackfin: bf52x/bf54x: fix up usb MMR defines
The bf52x/bf54x have the incorrect addresses for USB_EP_NI7_RXINTERVAL
and USB_EP_NI7_TXCOUNT, so adjust those.

Further, the bf54x header puts the USB defines in the wrong place, so
shuffle them back to the right grouping.

d09fb60203 Blackfin: debug-mmrs: fix typos with gptimers/mdma/ppi
This code was mostly developed against a BF54x, so some BF537-specific
issues were missed.

The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse
of the EPPI block).

The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG.  Seems the
sim does not catch misreads here so that'll need to get fixed.

The gptimer block is mostly 32bit regs, not 16bit.  Use the gptimer struct
to figure that out rather than hardcoding it locally.

* setns:
  ns: Wire up the setns system call

addition of sendmmsg system call

7b21fddd08 ns: Wire up the setns system call
32bit and 64bit on x86 are tested and working.  The rest I have looked
at closely and I can't find any problems.

setns is an easy system call to wire up.  It just takes two ints so I
don't expect any weird architecture porting problems.

While doing this I have noticed that we have some architectures that are
very slow to get new system calls.  cris seems to be the slowest where
the last system calls wired up were preadv and pwritev.  avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h.  frv is
behind with perf_event_open being the last syscall wired up.  On h8300
the last system call wired up was epoll_wait.  On m32r the last system
call wired up was fallocate.  mn10300 has recvmmsg as the last system
call wired up.  The rest seem to at least have syncfs wired up which was
new in the 2.6.39.

v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
v7: ported to Linus's latest post 2.6.39 tree.

5ca43f6c3b lib: consolidate DEBUG_STACK_USAGE option
Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way.  Move it
to lib/Kconfig.debug so each arch doesn't have to define it.  This
obviously makes the option generic, but that's fine because the config is
already used in generic code.

It's not obvious to me that sysrq-P actually does anything caution by
keeping the most inclusive wording.

Multiple Simultaneous Urgent DMA Requests May Cause DMA System Instability

the DMA block to group accesses together rather than allow arbitration for
each piece of data placed on the internal DMA bus.

c977819d01 Blackfin: delete duplicated user single step prototypes
These are in linux/ptrace.h, so no need for us to duplicate them.

c505217ca0 Blackfin: kgdb: cache flushing is not safe in SMP mode
Make sure we mark cache flushing as unsafe to kgdb in SMP mode so that
kgdb doesn't flush things incorrectly on us.

2951acba85 Blackfin: SMP: drop unused blackfin_cpudata.idle pointer
Not sure when we stopped using this field, but nothing in the tree uses
this now, so punt it.

44491fbc5a Blackfin: SMP: fix cpudata cache setup
After some cache setup reordering changesets, the blackfin_cpudata init
was left behind.  While cpu0's data was correct, cpu1's data was not.
Not that big of a deal as these are only used in the cpuinfo output, but
should still be fixed.  So move the setup of these fields to the common
cache setup function to avoid this happening again in the future.

8d011f70b0 Blackfin: clean up /proc/cpuinfo output
The smp flush lines are too long and have too many newlines, so scale
them back to match the other lines.

The %p modifier shows "(null)" for 0, so use %08x instead.

Build the sound pieces that the board actually has into the kernel, and
punt older devices that we discourage.
