Some MIPS ISA processor varients can do hweight operations
efficiently.
Split arch_hweight.h into a seperate file, and implement the
operations with __builtin_popcount{,ll} if supported.

Shamelessly stealing wisdom from pasemi_mac.c, I found char2hex() could
be replaced with a single call to sscanf(), looks cleaner to me at
least. The result is 100 bytes trimmed off the size of a compiled
cpmac_get_mac() and as an extra bonus it grumbles and gracefully fails
over to using random_ether_addr() when an attempt to parse an invalid
MAC address is made.

Additional changes to Youichi Yuasa's command line simplication code
The PowerTV platform uses a non-standard way to get the kernel command
line--we insert a built-in command line into arcs_cmdline and to
get additional command line information from the bootloader via a
pointer in the a1 register. It is necessary to insert a space between
to the two strings or the last argument from arcs_cmdline and the first
argument from the bootloader may be inadvertantly combined.
It is also necessary to set CONFIG_CMDLINE_BOOL to "y" and to set the
default command line to an empty string to get the simplified code to
work properly in the PowerTV environment.

When a secondary CPU is being brought up, it is not uncommon for
printk() to be invoked when cpu_online(smp_processor_id()) == 0. The
case that I witnessed personally was on MIPS:
http://lkml.org/lkml/2010/5/30/4
If (can_use_console() == 0), printk() will spool its output to log_buf
and it will be visible in "dmesg", but that output will NOT be echoed to
the console until somebody calls release_console_sem() from a CPU that
is online. Therefore, the boot time messages from the new CPU can get
stuck in "limbo" for a long time, and might suddenly appear on the
screen when a completely unrelated event (e.g. "eth0: link is down")
occurs.
This patch modifies the console code so that any pending messages are
automatically flushed out to the console whenever a CPU hotplug
operation completes successfully or aborts.
The issue was seen on 2.6.34.
Original patch by Kevin Cernekee with cleanups by akpm and additional fixes
by Santosh Shilimkar. This patch superseeds

- use hostprogs-y for the elf2ecoff
- list all *.o file in targets
- renamed obj-y to vmlinuzobjs-y (it was confusing to re-use a kbuild variable)
- fix all uses of if_changed/cmd
- use kbuild rules to beautify output
- update clean-file to clean vmlinuz.* in top-level directory
- simplied logic in arch/mips/Makefile for compressed targets
The net result is a more kbuild conformant Makefile but
readability did not increase.

It was sharing the nxp directory but no code with pnx833x and will fit
better into the new platform makefile scheme, if moved. Also after the
pnx833x code has been moved up, the pnx8550 Code was the last users of
the nxp dir.

Move platform specific definitions to the platfrom directories.
Each platform shall do the following:
1) include an entry in arch/mips/Kbuild.platforms
2) add relevant definitions to arch/mips/<platform>/Platform
This commits changes ar7 to the new scheme as an example.
Introducing a platform speecific Platfrom file has following advantages:
1) decentralization of platfrom definitions
2) simplification af arch/mips/Makefile
3) force all platfrom to build with -Werror (done in arch/mips/Kbuild)

Adding subdirs-ccflags-y := -Werror to arch/mips/Kbuild
let us in one go cover all files with -Werror.
In addition this allows us to remove the
individual -Werror definition in various Makefile.
Adding the definition to Kbuild as a recursive
option help us not to forget to do so.
With this change we now compile arch/mips/kernel/cpufreq with -Werror
One drawback:
When specifying a subdirectory covered by the Kbuild file like this:
make arch/mips/kernel/
then kbuild fails to pick up the -Werror definition.
