And I just noticed...

These are never used - and only defined a few places:
#define inb_p(addr)     inb(addr)
#define inw_p(addr)     inw(addr)
#define inl_p(addr)     inl(addr)
#define outb_p(x, addr) outb((x), (addr))
#define outw_p(x, addr) outw((x), (addr))
#define outl_p(x, addr) outl((x), (addr))

Likewise for these:
#define insb_p(port,to,len)     insb(port,to,len)
#define insw_p(port,to,len)     insw(port,to,len)
#define insl_p(port,to,len)     insl(port,to,len)

#define outsb_p(port,from,len)  outsb(port,from,len)
#define outsw_p(port,from,len)  outsw(port,from,len)
#define outsl_p(port,from,len)  outsl(port,from,len)



This set:
#define inb_p(addr)     inb(addr)
#define inw_p(addr)     inw(addr)
#define inl_p(addr)     inl(addr)
#define outb_p(x, addr) outb((x), (addr))
#define outw_p(x, addr) outw((x), (addr))
#define outl_p(x, addr) outl((x), (addr))

Should have a comment that say they are deprecated.
Especially the "b" variants still have many users.
