hmm, for some reason linux-mm keeps on rejecting this email. Maybe

The crash is caused by the below changeset. I was using my own .config so
the defconfig update is not the cause. I guess either the pageattr.c
changes or the instruction replacements. The lesson here is to split dem
patches up a bit!
Anyway. Over to you, Andi.

# [PATCH] x86-64 updates
#
# Various accumulated x86-64 patches and bug fixes.
#
# It fixes one nasty bug that has been there since NX is used by
# default in the kernel. With heavy AGP memory allocation it would
# set NX on parts of the kernel mapping in some corner cases, which gave
# endless crash loops. Thanks goes to some wizards in AMD debug labs
# for getting a trace out of this.
#
# Also various other fixes. This patches only changes x86-64 specific
# files, i have some changes outside too that I am sending separately.
#
# - Fix help test for CONFIG_NUMA
# - Don't enable SMT nice on CMP
# - Move HT and MWAIT checks up to generic code
# - Update defconfig
# - Remove duplicated includes (Arthur Othieno)
# - Set up GSI entry for ACPI SCI correctly (from i386)
# - Fix some comments
# - Fix threadinfo printing in oopses
# - Set task alignment to 16 bytes
# - Handle NX bit for code pages correctly in change_page_attr()
# - Use generic nops for non amd specific kernel
# - Add __KERNEL__ checks in unistd.h (David Lee)
