MIPS: Make the debugging of compressed kernel configurable

This patch adds a new DEBUG_ZBOOT option to allow the users to enable it
to debug the compressed kernel support for a new board and this optoin
should be disabled to reduce the kernel image size and speed up the
kernel booting procedure when the compressed kernel support is stable.

The userspace runtime linker uses the elf_platform to find the libraries

GLIBC already does the right thing.  The kernel just needs to supply good

MIPS: Loongson: Cleanup the halt and poweroff action

In the old source code, I have let halt and poweroff do the same action,
but in reality, they have different meanings.

As the manpage of shutdown shows:

-r     Reboot after shutdown.
-H     Halt action is to halt or drop into boot monitor on systems that support it.
-P     Halt action is to turn off the power.

and in the real world, some machines(e.g. NAS) did not provide a power
button and the shutdown works as reset, so, we need to provide a
mechanism to let the users turn off the power safely without breaking
the system, such a mechanism is "halt", which only put the system into a
dead loop or a power-save mode and print some information to the screen
to tell the users to turn off the power safely.

$ shutdown -hH now /* loongson_halt, not turn off the power */
$ shutdown -hP now /* loongson_poweroff, work as poweroff */

MIPS: Octeon: Use optimized memory barrier primitives.

In order to achieve correct synchronization semantics, the Octeon port
had defined CONFIG_WEAK_REORDERING_BEYOND_LLSC.  This resulted in code
that looks like:

   sync
   ll ...
   .
   .
   .
   sc ...
   .
   .
   sync

The second SYNC was redundant, but harmless.

Octeon has a SYNCW instruction that acts as a write-memory-barrier
(due to an erratum in some parts two SYNCW are used).  It is much
faster than SYNC because it imposes ordering on the writes, but
doesn't otherwise stall the execution pipeline.  On Octeon, SYNC
stalls execution until all preceeding writes are committed to the
coherent memory system.

Using:

    syncw;syncw
    ll
    .
    .
    .
    sc
    .
    .

Has identical semantics to the first sequence, but is much faster.
The SYNCW orders the writes, and the SC will not complete successfully
until the write is committed to the coherent memory system.  So at the
end all preceeding writes have been committed.  Since Octeon does not
do speculative reads, this functions as a full barrier.

The patch removes CONFIG_WEAK_REORDERING_BEYOND_LLSC, and substitutes
SYNCW for SYNC in write-memory-barriers.

The default implementation of smp_mb__before_llsc() is just smp_llsc_mb(),
so there are no changes in semantics.

Also simplify definition of smp_mb(), smp_rmb(), and smp_wmb() to be just
barrier() in the non-SMP case.

SERIAL 8250: Fixes for Alchemy UARTs.

Limit the amount of address space claimed for Alchemy serial ports to
0x1000. On the Au1300, ports are only 0x1000 apart, and the registers
only extend to 0x110 at most on all supported alchemy models.

On the Au1300 the autodetect logic no longer works and this makes it
necessary to specify the port type through platform data. Because of
this the MSR quirk needs to be moved outside the autoconfig() function
which will no longer be called when UPF_FIXED_TYPE is specified.

MIPS: Alchemy: prom_putchar is board dependent

This patch replaces the general alchemy prom_putchar() implementation
in favor of board-specific versions: The UART where the output of

implementation hardcodes this on a per-SoC basis which is just wrong.

So a generic uart tx function is provided in the alchemy headers,
and the boards can provide their own prom_putchar with custom
destination uart, and all in-kernel alchemy boards support
early printk.

This patch also renames the GPIO irq number constants. It's really
an interrupt line, NOT a GPIO number!

Code which relied on certain irq numbers to have the same name
across all supported cpu subtypes is changed to determine current
cpu subtype at runtime; in some places this isn't possible so
a "compat" symbol is used.

Remove EXPERIMENTAL from NFS_FSCACHE

There's currently an open Ubuntu bug[0], with the intent to compile NFS_FSCACHE
(and possibly AFS_FSCACHE, 9P_FSCACHE) into the standard Ubuntu kernel.
However, since *_FSCACHE still depends on EXPERIMENTAL, this won't happen.

As Arjan van de Ven pointed out[1], the EXPERIMENTAL flag doesn't mean that
much any more, I propose the following patch to fs/nfs/Kconfig. I'd do the
same for fs/9p/Kconfig and fs/afs/Kconfig, but as I did not test 9p or AFS, I
feel it would not be appropriate for me to remove the flag.

dvb-core: Fix DoS bug in ULE decapsulation code that can be triggered by an invalid Payload Pointer

ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation
has a bug that causes endless loop when Payload Pointer of MPEG2-TS
frame is 182 or 183. Anyone who sends malicious MPEG2-TS frame will
cause the receiver of ULE SNDU to go into endless loop.

This patch was generated and tested against linux-2.6.32.9 and should
apply cleanly to linux-2.6.33 as well because there was only one typo
fix to dvb_net.c since v2.6.32.

This bug was brought to you by modern day Santa Claus who decided to
shower the satellite dish at Keio University with heavy snow causing
huge burst of errors. We, receiver end, received Santa Claus's gift in
the form of kernel bug.

Care has been taken not to introduce more bug by fixing this bug, but
please scrutinize the code for I always produces buggy code.
