I did not find examples about how it works. I tried the following
syntaxes without any effect:
cpuid=PAT
cpuid=pat
cpuid_mask_edx=0xfffeffff
cpuid_mask_edx=4294901759 

However, patching pat_init() in NetBSD kernel to not wrmsr (I overwrote
the end of the function with nops using gdb) made it to multiuser.
