[LinuxBIOS] [PATCH] fix getpir with bit userspace

[Rudolf Marek]

Hello,

attached patch fixes SIGSEGV with 64-bit userspace. The memmem is implicit with 
int but it get signed extended when cast to rt. Cannot include correct headers
because of the kernel one. I also fixed the print output (it should not hurt).
