Impact: reduce scope of debug check - avoid warnings
The logic to find whether identity map exists or not using
high_memory or max_low_pfn_mapped/max_pfn_mapped are not complete
as the memory withing the range may not be mapped if there is a
unusable hole in e820.
Specifically, on my test system I started seeing these warnings with
tools like hwinfo, acpidump trying to map ACPI region.

We can add logic to check for this. But, there can also be other holes in
identity map when we have 1GB of aligned reserved space in e820.
This patch handles it by removing the WARN_ON and returning a specific
error value (EFAULT) to indicate that the address does not have any
identity mapping.
The code that tries to keep identity map in sync can ignore
this error, with other callers of cpa still getting error here.

Impact: avoid warning message, potentially solve 3D performance regression
Change x86 PAT code to return compatible memtype if the exact memtype that
was requested in remap_pfn_rage and friends is not available due to some
conflict.
This is done by returning the compatible type in pgprot parameter of
track_pfn_vma_new(), and the caller uses that memtype for page table.
Note that track_pfn_vma_copy() which is basically called during fork gets the
prot from existing page table and should not have any conflict. Hence we use
strict memtype check there and do not allow compatible memtypes.
This patch fixes the bug reported here:
http://marc.info/?l=linux-kernel&m=123108883716357&w=2
Specifically the error message:
X:5010 map pfn expected mapping type write-back for d0000000-d0101000,
got write-combining
Should go away.

Impact: cleanup

Impact: fix (harmless) double-free of memtype entries and avoid warning
On track_pfn_vma_new() failure, reset the vm_flags so that there will be
no second cleanup happening when upper level routines call unmap_vmas().

Specifically the error message:

Because the ipoib_workqueue is not flushed when ipoib interface is
brought down, ipoib_mcast_join() may trigger a join to the broadcast
group after priv->broadcast was set to NULL (during cleanup). This
will cause the system to be a member of the broadcast group when
interface is down. As a side effect, this breaks the optimization of
setting the Q_key only when joining the broadcast group.

There has been some light flamewar on lkml about decoding oopses
in modules (as part of the crashdump flamewar).
Now this isn't rocket science, just the markup_oops.pl script
cheaped out and didn't handle modules. But really; a flamewar
all about that?? What happened to C++ in the kernel or reading
files from inside the kernel?
This patch adds module support to markup_oops.pl; it's not the
most pretty perl but it works for my testcases...

Support for the FPGA based watchdog timer on GE Fanuc's SBC610.
This patch enables one of the watchdog timers found on the SBC610. There are
two identical watchdog timers at different offsets in the above mentioned
boards, however the current driver is only capable of supporting one of them.
The watchdog timers are also capable of generating interrupts at a
user-configurable threshold, though support for this operation is currently
not supported by the driver.
