Note that the emulation root is linux32 when running i386 linux programs
on an amd64 system.
Note that paths that start /../ are only looked up in the real root.
Modify the bug/note about symlinks not being looked up in the emulation root.
Some of this stuff ought to be in a generic 'emulation' man page.
I think it existed to cache the numbers in kernel memory of a zombie when
proc->p_stats was part of the 'u' area - so got freed earlier and wouldn't
(easily) be accessible from a separate process. However since both the
p_ru and p_stats fields are freed at the same time it is no longer needed.
Ride the recent 4.99.19 version change.
disk framework. This stops ld(4) from returning an error for various
ioctl() requests which actually *did* work. As a result fdisk(8) and
therefore also sysinst(8) work with ld(4) devices once again.
Based on a patch supplied by Todd Kover in PR kern/36244, successfully
tested with ld(4)@icp(4).
Seems to be quite stable. Some work still left to do.
Please note, that syscalls are not yet MP-safe, because
of the file and vnode subsystems.

- NetBSD's "newfs" doesn't accept a second (non-option) argument.
Patch provided by Jeff Ito in PR bin/36241.
- Use "sd0" instead of "rp0" because NetBSD's doesnt have a disk driver
called "rp".
- Use "/dev/rst0" instead of "/dev/rst8". With NetBSD's device numbering
scheme a system would have to have 9 tape drives to get "/dev/rst8".

Saves replicating a lot of code in the compat functions (esp. for
getvfsstat) at a cast of an extra function call in the non-emulated case -
which is unlikely to be measurable given the other costs of the actions
involved (even on vax).
Remove dofhstat() and dofhstatvfs() (and the last caller).
Remove some redundant stackgap_init() calls.
