mrg d914a3c1b9 remove clause 3 from all my licenses that aren't conflicting with 
another copyright claim line.  again.  (i did this in 2008 and then
did not update all of my personal templates.)

mrg f405a45af6 remove KERNHIST_INIT_STATIC(). it stradles the line between usable 
early in boot and broken early in boot by requiring a partly static
structure with another structure that must be present by the time
any uses are performed.  theoretically platform code could allocate
a chunk while seting up memory and assign it here, giving a dynamic
sizing for the entry list, but the reality is that all users have
a statically allocated entry list as well.

the existing KERNHIST_LINK_STATIC() is used in conjunction with
KERNHIST_INITIALIZER() instead.

this stops a NULL pointer deref when the _LOG() macro is called
before the storage is linked in, which happens with GCC 10 on OCTEON
with UVMHIST enabled, crashing in very early kernel init.

matt 1a23213bde Use UVMHIST_INITIALIZER (KERNHIST_INITIALIZER) to statically initialize 
maphist.  This allows maphist to used very very early in boot well before
uvm has been initialized.

matt fd2366536d -fno-common broke kernhist since it used commons. 
Add a KERNHIST_DEFINE which is define the kernel history.
Change UVM to deal with the new usage.

mrg 8169e46991 move and rename the uvm history code out of uvm_stat to "kernhist". 
rename "UVMHIST" option to enable the uvm histories.

TODO:
- make UVMHIST properly depend upon KERNHIST
- enable dynamic registration of histories.  this is mostly just
  allocating something in a bitmap, and is only for viewing multiple
  histories in a merged form.


tested on amd64 and sparc64.

perry fbae48b901 Change "inline" back to "__inline" in .h files -- C99 is still too 
new, and some apps compile things in C89 mode. C89 keywords stay.

dbj 5b4c9f2016 rearrange struct uvm_history to put the struct simplelock at the end. 
This avoids problems with the kernel grovelling vmstat -u/-U when
using LOCKDEBUG, which changes the size of struct simplelock.
Replaced the original location of the simplelock with "int unused"
so that binary compatibility will be retained with old vmstat.

mrg f63fe467c9 Add new history grovelling function uvm_hist() that takes a bitmask of 
histories to merge in cronological order.  currently, MAPHIST and
PDHIST are defined as 1 and 2 respectively.  passing a bitmask of 0
to uvm_hist() will dump all maps.

thorpej 872181c2f2 A few changes to make it possible to read UVM histories from userland: 
- Protect option headers from inclusion if ! _KERNEL or if _LKM.
- Make sure struct uvm_history is always the same size (not dependent
  on NCPU).
- Add fmtlen and fnlen members to struct uvm_history_ent, which specify
  the lengths fo the fmt and fn strings.
- Add name, namelen, and a list entry to struct uvm_history.
- When a history is initialized, place it on the global list of all histories.

thorpej 90aee42d35 Provide a patchable knob (uvmhist_print_enabled) so that UVM history 
buffer printing can be switched on and off at run-time.  Only exists
