f197609d93 Add some DIAGNOSTIC checks for inconsistent use of pmap_enter/pmap_kremove. 1999-05-25 20:33:33 +00:00

f311a1c308 Make a slight modification of pmap_growkernel() -- it now returns the 
end of the mappable kernel virtual address space.  Previously, it would
get called more often than necessary, because the caller only new what
was requested.

Also, export uvm_maxkaddr so that uvm_pageboot_alloc() can grow the
kernel pmap if necessary, as well.  Note that pmap_growkernel() must
now be able to handle being called before pmap_init().

e4a87aa1a9 * convert to using MI allocsys(). most ports were using an MD allocsys(), 
although a couple still used the old pre-4.4-lite (?) mechanism.
* use format_bytes() to format the various printf()s that print out memory sizes

c10a926030 Allow the caller to specify a stack for the child process. If NULL, 
the child inherits the stack pointer from the parent (traditional
behavior).  Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.

This is required for clone(2).

5f3034757f Move the user-set LDT out of the PCB and into the pmap. Applications 
which set the LDT and share VM space (e.g. new versions of WINE) expect
the LDT to be logically coupled to the address space.  Use the new pmap_fork()
interface to copy non-shared user-set LDTs when the address space is forked.

9c6b797796 Changes for modified pmap_enter() API: 
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
  because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
  avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot.  Also, DO NOT use
  pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
  access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
  access_type = 0.  This should probably be revisited.
