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. Sam
