Now that we have pud/pmd mask interfaces, which handle pfn & flags
mask properly for the large PAT bit.
Fix pud/pmd pfn & flags interfaces by replacing PTE_PFN_MASK and
PTE_FLAGS_MASK with the pud/pmd mask interfaces.

Looks like this commit is causing this splat for 32-bit kernels. I am
attaching my config file, just in case.
Thanks for the report! I'd like to reproduce the issue since I am not sure how
this change caused it...
I tried to build a kernel with the attached config file, and got the following
error. Not sure what I am missing.
----
$ make -j24 ARCH=i386
:
LD drivers/built-in.o
LINK vmlinux
./.config: line 44: $'\r': command not found
I wonder whether my email client added ^Ms to the file that I send. It
shouldn't have.
Makefile:929: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 127

Do you have steps to reproduce the issue? Or do you see it during boot-time?
This always happens just after system has booted, it may still be going
over init scripts. I am booting with ramdisk, don't know whether it has
anything to do with this problem.
FWIW, it looks like pmd_pfn_mask() inline is causing this. Reverting it
alone makes this crash go away.
