Patch from Alexander Schulz

This patch adds the define for PCIMEM_BASE so that the shark kernel
compiles again.

Patch from Dave Jiang

The fix allows IOP321 based platforms to boot all the way instead of
blank screen after "starting kernel...".  Inherited from Deepak's
earlier patch. 

This fixes initrd with devfs.  With that combination the late-boot code
does temporary mount of devfs over rootfs /dev, which made /dev/initrd
inaccessible.  For setups without devfs that didn't happen. 

The fix is trivial - put the file in question outside of /dev; IOW,
we simply replace "/dev/initrd" with "/initrd.image" in init/*.

... as if "nohide" is in used, it will be the wrong filehandle, and
returning a filehandle is optional anyway.

When raid0 needs to split a request, it uses 'block' (1K) addresses
rather than sector (512b) addresses, which causes problems if the sector
address is odd.  This patch fixes the problem.

As found by Herbert Xu: the last v4l update broke bttv.  videobuf_iolock
was passed a vb that has just been filled with zeros. 

Fixed like this.

The Silicon Image driver is not building properly when CONFIG_PROC_FS is unset.
This patch corrects that problem.  It appears as though several utility
functions at the top of drivers/ide/pci/siimage.c that the driver always needs
accidentally fell within an #ifdef CONFIG_PROC_FS.  I also removed an excess
include while I noticed it.

- converts hdr_cur_pos into hdr_cur_offs to avoid leaking kernel
  addresses to userland. As a consequence hdr_last_pos is gone.

- correct buffer saturation mode bug by which the hdr_count would
  be reset, leading to no visible samples collected.

Newer versions of strace manipulate the syscall arguments and to make this
work for ia32 processes, we need to reload the syscall args after
doing the syscall-trace callback.

	enable_irq() sequences).

Tony pointed out (thanks Tony) that in -test8 kobject_set_name() will
try to free a kobject's k_name field if it's non-NULL, so we need to
zero it out in case kmalloc() gave us recycled memory or we'll try to
kfree a bogus area.

This fixes a problem in EFI memory map trimming. For example,
here's part of the memory map on my i2000:

    mem00: type=4, attr=0x9, range=[0x0000000000000000-0x0000000000001000) (0MB)
    mem01: type=7, attr=0x9, range=[0x0000000000001000-0x0000000000088000) (0MB)
    mem02: type=4, attr=0x9, range=[0x0000000000088000-0x00000000000a0000) (0MB)
    mem03: type=5, attr=0x8000000000000009, range=[0x00000000000c0000-0x0000000000100000) (0MB)
    mem04: type=7, attr=0x9, range=[0x0000000000100000-0x0000000004000000) (63MB)
    mem05: type=2, attr=0x9, range=[0x0000000004000000-0x00000000049ba000) (9MB)
    mem06: type=7, attr=0x9, range=[0x00000000049ba000-0x000000007ec0b000) (1954MB)
    ...

There's a hole at 0xa0000-0xc0000, so we should ignore all the WB memory
in that granule.  With 16MB granules, the existing code trims like this
(note the 4K page at 0x0 should have been ignored, but wasn't).

Populate topology directories correctly now that NUMA kernels work.

They were added by Torben to workaround ServerWorks driver problems
(fixed by previous patch), but depending on BIOS can be dangerous on
other chipsets and it is always better to fix specific driver.

Removal of these options was acked by Torben.

If PIO mode should be auto-tuned xferspeed argument for svwks_tune_chipset()
is equal to 255 (0xFF).  It is then passed to ide_rate_filter() which matches
desired mode with chipset capabilities.  Since 255 is greater than any of the
values used for transfer modes, ide_rate_filter() will always return the
highest mode supported by both device/chipset (which sometimes should not be
used ie. when host is a simplex one) and the wrong mode will be set.

Thanks to Torben Mathiasen and Tomas Szepe for testing it.

The original change turned out to be too restrictive, it catches devices
that don't need the work around.

This fixes that, thanks to Bart for informing me of the screwup.
