A workaround for flash memory I/O errors when the PS3 internal
hard disk has not been formatted for OtherOS use.

This error condition mainly effects 'Live CD' users who have not
formatted the PS3's internal hard disk for OtherOS.

Fixes errors similar to these when using the ps3-flash-util
or ps3-boot-game-os programs:

  ps3flash read failed 0x2050000
  os_area_header_read: read error: os_area_header: Input/output error
  main:627: os_area_read_hp error.
  ERROR: can't change boot flag

probe functions should be __devinit
initialization functions should be __init

Change the ps3av_auto_videomode() mode id argument type from unsigned to
signed so a negative id can be detected and reported as an -EINVAL failure.

We just fix up the reference parameters as the others are dealt with by
arithmetic promotion rules and don't cause warnings.

This removes warnings like this:

arch/powerpc/platforms/ps3/interrupt.c:327: warning: passing argument 1 of 'lv1_construct_event_receive_port' from incompatible pointer type

Also, these:

drivers/ps3/ps3-vuart.c:462: warning: passing argument 4 of 'ps3_vuart_raw_read' from incompatible pointer type
drivers/ps3/ps3-vuart.c:592: warning: passing argument 4 of 'ps3_vuart_raw_read' from incompatible pointer type

Introduce ps3_gpu_mutex to synchronizes GPU-related operations, like:
  - invoking the L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT command using the
    lv1_gpu_context_attribute() hypervisor call,
  - handling the PS3AV_CID_AVB_PARAM packet in the PS3 A/V Settings driver.

Compiling with CONFIG_SMP = n and CONFIG_PS3_LPM != n gives this error:

drivers/ps3/ps3-lpm.c:838: error: implicit declaration of function 'get_hard_smp_processor_id'

This fixes it.  We have to include <asm/smp.h> rather than
<linux/smp.h> because the UP definition of get_hard_smp_processor_id()
is in <asm/smp.h>, and <linux/smp.h> only includes <asm/smp.h> if
CONFIG_SMP = y.

Add support for the channel status bit setting so that non-PCM
