* setns:
  ns: Wire up the setns system call

Done as a merge to make it easier to fix up conflicts in arm due to

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.

63ab25ebbc kgdbts: unify/generalize gdb breakpoint adjustment
The Blackfin arch, like the x86 arch, needs to adjust the PC manually
after a breakpoint is hit as normally this is handled by the remote gdb.
However, rather than starting another arch ifdef mess, create a common
GDB_ADJUSTS_BREAK_OFFSET define for any arch to opt-in via their kgdb.h.

943aee0c68 Blackfin: SMP: make all barriers handle cache issues
When suspending/resuming, the common task freezing code will run in
parallel and freeze processes on each core.  This is because the code
uses the non-smp version of memory barriers (as well it should).

The Blackfin smp barrier logic at the moment contains the cache sync
logic, but the non-smp barriers do not.  This is incorrect as Rafel
summarized:
> ...
> The existing memory barriers are SMP barriers too, but they are more
> than _just_ SMP barriers.  At least that's how it is _supposed_ to be
> (eg. rmb() is supposed to be stronger than smp_rmb()).
> ...
> However, looking at the blackfin's definitions of SMP barriers I see
> that it uses extra stuff that should _also_ be used in the definitions
> of the mandatory barriers.

61f2e7b0f4 bitops: remove minix bitops from asm/bitops.h
minix bit operations are only used by minix filesystem and useless by
other modules.  Because byte order of inode and block bitmaps is different
on each architecture like below:

m68k:
	big-endian 16bit indexed bitmaps

h8300, microblaze, s390, sparc, m68knommu:
	big-endian 32 or 64bit indexed bitmaps

m32r, mips, sh, xtensa:
	big-endian 32 or 64bit indexed bitmaps for big-endian mode
	little-endian bitmaps for little-endian mode

Others:
	little-endian bitmaps

In order to move minix bit operations from asm/bitops.h to architecture
independent code in minix filesystem, this provides two config options.

CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k.
CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use
native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu,
m32r, mips, sh, xtensa).  The architectures which always use little-endian
bitmaps do not select these options.

Finally, we can remove minix bit operations from asm/bitops.h for all
architectures.

c6345ab1a3 Blackfin: SMP: work around anomaly 05000491
In order to safely work around anomaly 05000491, we have to execute IFLUSH
from L1 instruction sram.  The trouble with multi-core systems is that all
L1 sram is visible only to the active core.  So we can't just place the
functions into L1 and call it directly.  We need to setup a jump table and
place the entry point in external memory.  This will call the right func
based on the active core.

In the process, convert from the manual relocation of a small bit of code
into Core B's L1 to the more general framework we already have in place
for loading arbitrary pieces of code into L1.

0f66e50af5 serial: bfin_5xx: split uart RX lock from uart port lock to avoid deadlock
The RX lock is used to protect the RX buffer from concurrent access in DMA
mode between the timer and RX interrupt routines.  It is independent from
the uart lock which is used to protect the TX buffer.  It is possible for
a uart TX transfer to be started up from the RX interrupt handler if low
latency is enabled.  So we need to split the locks to avoid deadlocking in
this situation.

In PIO mode, the RX lock is not necessary because the handle_simple_irq
and handle_level_irq functions ensure driver interrupt handlers are called
once on one core.

And now that the RX path has its own lock, the TX interrupt has nothing to
do with the RX path, so disabling it at the same time.

57afb39935 serial: bfin_5xx: move resources into board files
Rather than maintain Kconfig entries where people have to enter raw
numbers and hardcode lists of addresses/pins in the driver itself,
push it all to platform resources.  This lets us simplify the driver,
the Kconfig, and gives board porters greater flexibility.

In the process, we need to also start supporting the early platform
interface.  Not a big deal, but it causes the patch to be bigger than
a simple resource relocation.

All the Blackfin boards already have their resources updated and in

b1524e29e3 Blackfin: bfin_serial.h: unify heavily duplicated serial code
Each Blackfin port has been duplicating UART structures and defines when
there really is no need for it.  So start a new bfin_serial.h header to
unify all these pieces and give ourselves a fresh start.

c925cf0b80 m68k{nommu}/blackfin : remove old assembler-only flags bit definitions
Long ago, PT_TRACESYS_OFF and friends were introduced as hard defines to
avoid straight constants in assembler parts of linux m68k.  They are not
used anymore, and were not updated to follow changes in linux kernel.
Remove them.  When similar constants are needed, they are now generated
using asm-offsets.c.
