who have machines that hit swap a lot. decided after survey of developers,
we found that most turned this on. ok various

other archs for now, beck theo ok
|

everybody please update your trees and test this, we need to find out
wether there is bad side-effects from the doubling. If this does not get
enough testing by our user community we will play safe and revert this for
the 3.7 release, so please test.

on all other architectures. remove last architecture dependent #ifdef from
uvm code.

|
|
|
Remove inline from a few functions, shrink the kernel by a few kB and
make things faster. A simple compilation on amd64 spends around 5%
less time in kernel.
Yes, it's faster without inlines, now go buy a book about modern cpu
architectures and find a chapter about the new and revolutionary thing
called "cache".

things such that code that only need a second-resolution uptime or wall
time, and used to get that from time.tv_secs or mono_time.tv_secs now get
this from separate time_t globals time_second and time_uptime.

change both the nointr and default pool allocators to using uvm_km_getpage.
change pools to default to a maxpages value of 8, so they hoard less memory.
change mbuf pools to use default pool allocator.
pools are now more efficient, use less of kmem_map, and a bit faster.

an interrupt safe thread.
use this as the new backend for mbpool and mclpool, eliminating the mb_map.
introduce a sysctl kern.maxclusters which controls the limit of clusters
allocated.
testing by many people, works everywhere but m68k. ok deraadt@
this essentially deprecates the NMBCLUSTERS option, don't use it.
this should reduce pressure on the kmem_map and the uvm reserve of static
map entries.

all architectures but arm, where it is needed.

- rijndael_set_key_enc_only() sets up context for encryption only
- rijndael_set_key() always sets up full context
- rijndaelKeySetupDec() gets back original protoype
- uvm: use _enc_only() interface

to prevent fragmentation.
this has the effect of randomizing unhinted mmap()s, sysV mem, and
position of ld.so.
tested on many archs by many developers for quite some time.
use of MIN to allow m68k to play from miod@.
vax is not included.

scattering ld.so and libraries around, although all mmaps will also
have some jitter too. better version after some discussion with drahn

argument. old cred only calls user suser_ucred. this will allow future
work to more flexibly implement the idea of a root process. looks like
something i saw in freebsd, but a little different.
use of suser_ucred vs suser in file system code should be looked at again,
for the moment semantics remain unchanged.

undefined flags are now rejected instead of silently ignored. makes
"unintentional" mprotect calls a touch harder.
