If you compile for an 486 or better the kernel assumes WP works right --
no check is performed other than the following one (this is taken from
include/asm-i386/bugs.h):
if (boot_cpu_data.x86 == 3)
panic("Kernel requires i486+ for 'invlpg' and other features");
You may actually check for "boot_cpu_data.x86_vendor == X86_VENDOR_NEXGEN"
here; hopefully the remaining code does not depend on the family directly.
