This commit was manufactured by cvs2svn to create tag

'RELENG_2_2_5_RELEASE'.

This commit was manufactured to restore the state of the 2.2.5-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

1. Fix the vm_page_zero_count accounting. This should improve the

1997-03-25T04:54:38+00:00

    performance of the pre-zero loop.
2.  Fix madvise.  It had a myriad of bugs, including the potential
    for system crashes.
3.  Improve vm_map handling.  This is a result of work done by both
     (Alan Cox) and me.  Earlier versions of the
    map handling code was very unintelligent about map coalescing.
4.  Support a working and closer to POSIX mlock.
5.  A couple of performance enhancements that came along for the ride,
    including changing certain bitfields to flags in vm_map.
6.  Bring procfs up to date with respect to the changes.

This code has been carefully extracted from -current.

Fix the /proc/???/map file so that it is possible to read an arbitrarily

large process map.  Another commit will follow to fix a problem just found
during this one... Sorry!!! :-(.

Modify slightly the output from the map file in /proc. Now the

1996-07-27T19:47:04+00:00

executable bit is shown.

Under certain circumstances, reading the /proc/*/map file can

1996-07-27T18:28:10+00:00

crash the system.  Nonexistant objects were not handled correctly.

Clean-up the new VM map procfs code, and also add support for executable

1996-06-18T05:16:00+00:00

format file "etype".  It contains a description of the binary type for
a process.

This file is the "meat" of the process address space capability. If you

1996-06-17T22:53:27+00:00

would like other things added, just ask!!!  It might be pretty easy to add.
