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]

The new atyfb has the return value for the Power Management routine
wrong. This prevents sleep from working on PowerBooks with mach64
video chips. This fixes it.

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
Committed-by: Grant Grundler <grundler@parisc-linux.org>

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.

 - Fix Astro/Elroy LMMIO space reporting in /proc/iomem.
 - Output in /proc/iomem include PCI bus number and "Extra LMMIO" range.
 - LBA now reports proper addresses routed down from SBA.
 - add mercury_cfg_ops. This fixes the tg3 init delay problem.
   PDC took ~20ms per PCI cfg write. tg3 performs ~1600 writes (~30 seconds
   per NIC) during init. Alternative is the relocate PDC to host ram.
   But that would burn ~4MB of RAM. This is cheaper.

Fixes mis-labelled timer variables, and incldes the

Patch from George G. Davis

The Lubbock PCMCIA socket driver, drivers/pcmcia/pxa2xx_lubbock.c,
lacks a MODULE_LICENSE declaration. This patch merely adds the missing
MODULE_LICENSE declaration to eliminate tainted kernel warnings when
this driver is built as a module. I have intentionally not used the
Dual MPL/GPL license in this case because 1) current linux-2.6.10-rc1
PXA PCMCIA drivers use only the GPL license, 2) the original source
files on which the PXA PCMCIA drivers are based, i.e. the SA11xx PCMCIA
drivers, state: "If you wish to allow the use of your version of this
file only under the terms of the GPL and not to allow others to use your
version of this file under the MPL, indicate your decision by deleting
the provisions above and replace them with the notice and other
provisions required by the GPL."

Here's the patch that supercedes the one I asked you to drop.  It changes
the fan speed logic so that the fans will go incrementally fast instead of
using just two steps.  Also, it starts and stops both fans instead of just
one on Powerbooks 15" and 17" (functionality asked by most of the Albooks
users on Debian's ML, and justified by the fact that fan 1 and fan 2 do not
correspond to CPU and GPU, as we previously thought).
