0726b418be Maps don't change that frequently between reads, so don't give up and 
do what linux does (support reading from an offset).

61e8303e9d Remove the "struct lwp *" argument from all VFS and VOP interfaces. 
The general trend is to remove it from all kernel interfaces and
this is a start.  In case the calling lwp is desired, curlwp should
be used.

a7761fd2c5 Instead of reading and writing little by little, allocate memory and 
write the whole map in one shot so that we don't have to deal with the
map changing under us. Fixes the linux emulated jdk-1.6 where it was
losing the last map entry and could not find the stack on startup.

42a7dff463 procfs_map(): 
- Drop the target's vm_map lock before calling uiomove(). We could
  deadlock if inspecting /proc/curproc/map.
- If the vm_map might have changed, restart the operation, but give
  up after 250 retries if the map keeps changing.  XXX This is not
  ideal.

934634a18c Change the process/lwp flags seen by userland via sysctl back to the 
P_*/L_* naming convention, and rename the in-kernel flags to avoid
conflict. (P_ -> PK_, L_ -> LW_ ). Add back the (now unused) LSDEAD
constant.

Restores source compatibility with pre-newlock2 tools like ps or top.

d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.

a06b275edc Undo part of the ktrace/lwp changes. In particular: 
* Remove the "lwp *" argument that was added to vget().  Turns out
  that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
  and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
  above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
  just to appease the above.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
