Asm tidy. * i386/i386/fpe_linkage.c (disable_fpe): Gather dependent asm statements, add `ax' clobber. (fpe_exception_fixup): Drop bogus cast from input parameter of lcall asm statement. * i386/i386/pio.h (inw, outw): Drop 0x66 prefix an just use the w instruction variant. * i386/i386/proc_reg.h: (get_eflags, get_tr, get_ldt): Drop useless "volatile" from asm statement. (get_esp): Use direct asm register specification. * i386/include/mach/i386/cthreads.h (cthread_sp): Likewise. * i386/intel/pmap.c (pmap_unmap_page_zero): Fix asm clobber into `eax'. De4x5 probe fixup. * linux/src/drivers/net/de4x5.c (pci_probe): Make probe loop stop on any error, not only device not found.
