thorpej e727e3f180 Split elf32 vs. elf64 handling in loadfile(), including support for
each separately and explicitly.  BOOT_ELF is now BOOT_ELF32 and
BOOT_ELF64, and ELFSIZE should no longer be defined in loadfile_machdep.h.

chris 0e7661f023 Update pmap_update to now take the updated pmap as an argument.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

kleink 99d1259e7f Don't let [gs]etcontext() and friends clash with userland. 2001-04-30 19:35:13 +00:00
thorpej 2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

lukem 20ba07f2fe - add dev_noimpl(xxx,yyy) macro to replace "(dev_type_xxx((*))) yyy",
and use appropriately

- create more helper macros:
   . cdev__xyz_init(c,n), such as cdev__ocri_init() for
     /* open, close, read, ioctl */, etc.
   . cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
     method `R' and the comments now read /* xxx (read) yyy */ instead
   . cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
     as well

- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
  always DTRT WRT returning a valid result.  (a few devices previously
  incorrectly returned ENODEV)

- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
  == 0, because it doesn't matter if dev_type_stop isn't implemented in that
  case, and it allows the use of the cdev__xyz_init macros. certain ports
  (sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
  drivers, whereas everything else uses enodev

- ensure that the comments are accurate WRT the behaviour of a given entry
