[gentoo-hardened] PaX and the availability of the NX bit on a CPU

[Pedro Venda]

Hi people,

I'm sorry if this is a well known issue, feel free to redirect me to a Fine 
Manual.

I'm installing a new server with the hardened profile, a PaX enabled kernel 
(PAGEEXEC) and a little of grsecurity. The cpu is a recent intel celeron with 
NX bit and 64bit extensions (whatever that means).

I was wondering if the PAGEEXEC feature of PaX is able to detect and 
transparently use the NX bit or if it's enabled for some particular 
architectures only...

I've compiled the kernel for pentium3 and built the system 
with -march=pentium3.

Best regards,
Pedro Venda.
