nisimura 7a50b38cbd - Adjust descriptive comment of cpu_fork() which returns nothing and 
returns once.
- Minor fixes in mips/vm_machdep.c.

thorpej 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).

scw 52b5bc5eb8 Duh. My last change broke mvme147 support. 1999-04-27 18:12:44 +00:00
thorpej b8073b401b Garbage-collect the VM_MBUF_SIZE constant. Instead, use the size 
(nmbclusters * mclbytes), so that the right amount of KVA space is
allocated if those variables are patched.

chs 05b971dd5f in pmap_pageable(), rather than marking a PT page as not modified 
to trick the pagedaemon into freeing it later, just unmap the page
and free it immediately.  fixes PR 7337.

allocations to use pages from the reserve.
use the new flag for allocations in pmap modules.

mycroft 93768384ee Fix a bug in pmap_collect_pv(), even though nobody currently uses it: 
When we put a page on the collection list, we must subtract NPVPPG from the
total free count: one for each pv_entry that's free in that page, and one for
each free pv_entry in other pages that we're going to eat by moving the ones
in the page being collected.

mycroft 12d512bbb7 Oops; vm_offset_t -> vaddr_t. 1999-03-27 00:30:06 +00:00
mycroft 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.

thorpej 587eda7c3f Use ETHER_*_LEN constants from <net/if_ether.h> instead of defining them 
ourselves.

mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

chs ab7269f62a if uvm_fault() fails with KERN_RESOURCE_SHORTAGE, send a SIGKILL 
and print a message about it.  this will be used to recover from
out-of-swap conditions.

disabled sync negotiation in the 147's SBIC driver. (I could never make
it work). Also, don't enable bus-snooping with a 68060 based board.

Make the initializer for BAUDLO depend on PCLK directly; it was incorrect on
some ports where PCLK is not 4.9152MHz.
XXX Is the default value actually used?
