The routine ext2_readdir() will, when reading a directory page
returns an error, try the next page, without reporting the
error to user space. That is bad, and the patch below changes that.

In my case the filesystem was damaged, and ext2_readdir wanted
to read 60000+ pages and wrote as many error messages to syslog
("attempt to access beyond end"), not what one wants.

[no doubt a similar patch is appropriate for ext3]

This preserves 2.4.x behavior.

bits_wanted is expanded to bytes using the wrong shift value
(when iovp_shift != PAGE_SHIFT), resulting in an explosion of
used iommu resources.

This potentially results in mistakenly running out of DMA mapping
resources when the system is under *heavy* i/o load.

Patch from Matthew Wilcox:
  Since some ia64 platforms have non-identity-mapped PCI busses, we need
  to implement pcibios_resource_to_bus and pcibios_bus_to_resource.
  Also clean up some >80 column comments and delete an unnecessary parameter
  to pcibios_fixup_device_resources().

No, this breaks the normal return path.

This patch allows tcpdiag to support ipv6 work as a module when itself
is also a module.

I was planning for a more extensible method but now I think the effort
would be better directed at a new generic socket netlink interface than
the TCP-specific tcpdiag.

XFree (and X.org) has both always been broken in their conversion of the DPMS
blanking mode when passing to the kernel ioctl FBIOBLANK (in fbdev mode).

This patch makes sure that at least the value passed by userland stays in the
legal range, which has the side effect that an X DPMS POWERDOWN request will
result as an fbdev VESA_POWERDOWN request at the fbdev level now, instead of
an out-of-range value.

Superio cleanup

The default interruption handler "handle_interruption" does not properly
check to see if the faulting space is the same as the users space.
The problem lies in the fact that if a fault happens on the gateway we
will not deliver signals to the process, the process will not die, and we
may continue handling the same fault in a loop forever.  Any malicious
user code can crash the kernel by jumping into the gateway page at an
inopportune address.

The solution is to check if the user has the right privilege and if the
spaces match, both faulting and currently active. The best action is to
force the process back to it's own space of execution at address zero, and
let it take a SIGSEGV. The process can never recover from this because it
happens immediately after the return from the interrupt via rfi or rfir.
