Need to use long long, not long when RMWing a MSR. I think it's harmless right now, but still should be better fixed if AMD adds any bits in the upper 32bit of HWCR. Bug was introduced with the TLB flush filter fix for i386 Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

To set up SMP
Configure the kernel and answer Y to CONFIG_SMP.
If you are using LILO, it is handy to have both SMP and non-SMP
kernel images on hand. Edit /etc/lilo.conf to create an entry
for another kernel image called "linux-smp" or something.
The next time you compile the kernel, when running a SMP kernel,
edit linux/Makefile and change "MAKE=make" to "MAKE=make -jN"
(where N = number of CPU + 1, or if you have tons of memory/swap
you can just use "-j" without a number). Feel free to experiment
with this one.
Of course you should time how long each build takes :-)
Example:
make config
time -v sh -c 'make clean install modules modules_install'
If you are using some Compaq MP compliant machines you will need to set
the operating system in the BIOS settings to "Unixware" - don't ask me
why Compaqs don't work otherwise.
